Freeview HD TVs: Best Buys

Nigel Whitfield.

We didn't say ...

.. that this was a comprehensive roundup of Freeview TVs. It's more of a snapshot, showing some of what's available.

And, to a large extent, we are reliant upon what manufacturers are able to send us, within the timescale for any given article. As has been remarked before, with some kit the answer from manufacturers has been "Go and look in John Lewis," which is hardly a suitable basis for a review.

I'm sorry we didn't include the sets that you personally are looking at, but that doesn't mean that other readers won't be interested in some of these, or indeed that we won't look at other models in future.

Buyer's Guide: Freeview HD TVs

Nigel Whitfield.

In fact

What I said in the piece was not that it's "tightly specced", but that it is more so than the standard def service. It's still not as tight as, say, Freesat, where the EPG layout and genre screens are controlled, but there are more restrictions than in the past.

The surround issue is something we've been following for a while - see last week's report here, and the stuff I've been publishing on my own blog for the last month. We'll have an update regarding that fairly soon, too, just as soon as some other people get back to us. It certainly far from ideal, to put it mildly.

However, I simply don't recognise the description of the Freeview picture quality as 'overly compressed crap' - have you watched it? And which bits of the H.264 video standard aren't being used properly?

A far more common reason for not being able to play recorded material from a PVR on other equipment is that that other equipment, while supporting the H.264 codec, does not necessarily understand how to get H.264 from an MPEG Transport Stream, which is what has to be broadcast - just as some kit also doesn't understand an MPEG2 video Transport Stream, and needs it turned into a Programme Stream before it can play back. A case, as Morecambe and Wise might say, of having all the right packets, but not necessarily in the right order.

Sky TV gets even more demanding

Look on the bright side

You may not get LLU, but you also don't get car alarms at 3am, loud music from parties in the flat next door, cleaner air, less light pollution, and plenty of other benefits.

You can vote wherever you live in the UK; but there will always be differences between living in a city and living in the country side. Wouldn't it be dull if life were exactly the same everywhere in the country?

Freeview HD sacrifices surround sound for World Cup scramble

Nigel Whitfield.

For many people ...

... it means precisely that.

Even where Freeview is broadcasting 5.1 audio, it's not in a format that most set top boxes or TVs are capable of passing on to home AV gear.

You might be able to create a psuedo-surround mix in your AV amp, but it would surely be better if the surround mix that's broadcast on Freeview HD from time to time could actually be fed into that amp, and delivered to the speakers.

With a very few exceptions, it cannot. The necessary bits to allow that to happen won't be mandatory until next year.

BBC One HD to launch this autumn

Nigel Whitfield.

HD is statmuxed

HD is stat-muxed at the moment, on the HD mux.

But I would imagine there are tremendous difficulties in stat-muxing together an HD service and an SD one, not least that both will be using different compression systems. If everything were in H.264 it might be straightforward, but on a mixed mux, it wouldn't be.

It's probably far easier to stat-mux SD services, and HD services, and then combine all into the transport stream to the transmitters - but that would then result in further inefficiencies, compared to having a separate T2 mux for HD only.

Nigel Whitfield.

What inefficiency?

Unfortunately, if you didn't have a separate mux, then you wouldn't be able to use the DVB-T2 modulations, which gives an additional 40% capacity. And, during some of HD tests over recent years, there were concerns that some existing receivers wouldn't be happy with mixed MPEG2 and H.264 on the same mux anyway.

On top of that, you'd probably end up having to use Dolby Digital for the surround sound, rather than any of the more efficient new codecs. And that in turn would mean that for Audio Description, you would either have to forgo it on the HD service, or broadcast an AD broadcaster mix, which wouldn't be terribly efficient.

Given that the HD service manages to provide audio (albeit with the current reservations regarding surround) with 320kbits of bandwidth, plus another 64 for AD, and the gain by using the HD mux is 40% extra capacity, I'd say that the use of a separate mux is far from inefficient.

The T2 mux gives, roughly, another 10Mbps of bandwidth. That far outweighs the potential saving of a few shared soundtracks, even if you could ensure that none of the installed base of boxes falls over when presented with a stream containing both types of video.

Buyer's Guide: Freeview HD Set-top Boxes

Nigel Whitfield.

We weren't testing recorders

In case you didn't notice, in your desire to plug them, this was a test of set top boxes, not of PVRs.

It would have been a little peculiar to put a single recorder in there when all the others are just standard zappers, wouldn't it?

We hope to be looking at PVRs later, but they're even harder to get hold of than the set top boxes, right now.

Freeview HD Set-top Boxes: Best Buys

Nigel Whitfield.

Transcoding

Transcoding needn't necessarily add much to the cost of a box; there's a Dolby design, for example, intended for specifically this application, which can do the whole lot at - so Dolby says - a lower licensing cost than the individual components.

And it appears that some of the boxes have that design, or something similar; since the test was published, for example, Humax has confirmed to me that a firmware update for their box will add transcoding from HE-AAC. I would hope that quite a few of the boxes out there will be able to do this too, though we shall have to wait and see the response of the manufacturers.

If you have an AV system that supports multi-channel audio via HDMI, then again you should be able to get surround out of these units.

If every single programme on the HD channels actually used surround sound, and I felt that the majority of people would be connecting to a surround system, I'd have attached more weighting to the issue, and that would have altered the scores somewhat.

But as things stand, a lot of what's being broadcast right now is still only in stereo - I had to wait until appropriate programmes appeared on BBC HD to check the functionality of each box. And many people will be looking at some of those other features too, just as much as sound.

It's certainly an important issue - I'd have glossed over it if I didn't think so - but at the moment, may not affect a huge number of people. The awards are calculated based on scores, and those boxes that scored highest did so because of their other functionality, or ease of use.

Nigel Whitfield.

Yep...

As I mentioned in another comment, there really isn't any significant different in the picture quality that I was able to see, even when switching between the boxes fairly quickly.

All are capable of outputting at 1080p, if you really want, and all appear to give just as good a rendition of the FreeviewHD signal, in my view. You'll see more variation due to the quality of the different programmes than you will between the way the different boxes handle HD.

Bush DVB680

Nigel Whitfield.

Not much in it, frankly

When it comes to picture quality, I think you'd be hard pushed to spot any significant difference between these boxes, frankly. I worked through all seven of them in quick succession when I was testing the surround functionality, as well as longer periods individually, and I honestly don't think any one stood out as better or worse than the others.

In terms of picture quality, you will generally be much more at the mercy of what's being broadcast then of the performance of your box, and so when it comes to choosing between them then it will fall far more to those other points on which I concentrated.

L'Orange and T'Mobile: Together at last

Nigel Whitfield.

really?

"Nothing, anywhere" would be a more accurate summation of my recent experiences, especially with Orange mobile data, in such out of the way backwoods as Canary Wharf and Winchester.

Samsung NaviBot robot cleaner

Nigel Whitfield.

I did point out ...

... that the results are quite acceptable in areas with normal levels of dirt, and it'll indeed do a fine job, even with cat hair and some of the other usual domestic detritus.

But had I not selflessly moved furniture and revealed the monstrous amounts of fluff lurking there, to see how well it coped with that, I'm sure someone would have been along to complain we didn't really put it through its paces.

Nigel Whitfield.

PBX

It's a junction box for the phone wiring, which lost its cover somewhere along the way. Probably came from somewhere like Maplin or maybe even Tandy, it was so long ago.

I used to have (until it died earlier this year) an ISDN pbx with internal analogue extensions. Now the skirting boards are cluttered with a mix of analogue phone lines, thin ethernet, ISDN and even a serial link from the old Wyse 50 that used to live in the kitchen and be used with WordPerfect for Unix.

Nigel Whitfield.

I prefer ...

... to think of it as "straight acting." My mother once remarked that no one would know I'm gay from the state of my flat.

As for the barber's chair, I got it from another filthy pervert. But I did see a rather fetching black Belmont one for sale in a second hand place on the Bethnal Green road a few weeks ago.

Nigel Whitfield.

The fridge is fine, thanks!

There's nothing untoward in the fridge. Everything in there has a sell by date from this century.

Nigel Whitfield.

It did try to escape!

The red cable in one of the photos is an ethernet link that it attempted to ingest in the living room, presumably in an attempt to upload to freedom.

Cambridge Audio Azur 650BD

Nigel Whitfield.

It's not major ...

... but some of us don't have a receiver with HDMI; I have a rather older Yamaha DSP E-800, which can handle the six channel audio input for SACD, and then pass that on to my amp, or decode the optical data. And since I use a Harmony remote, it's not much of an inconvenience to have the BD player connected directly to the TV via HDMI.

The reason I think I - and some others - might like the stereo output is for when you are listening to stereo material (like CD), and want to cut one extra bit out of the chain, sending stereo direct to the pre-amp, rather than passing in through the six channel inputs of the AV processor. Admittedly that's a small thing, but since they've gone to the trouble of having the 'audio mode' that shuts down a lot of the video circuitry, it seems a shame not to go the whole hog and have a separate stereo output.

The DVD player I normally use for CD and SACD, a Samsung DVD-HD950, does manage both the six channel and stereo outputs. Perhaps if I'd never had them, I wouldn't miss them.

I'm fairly sure that, while the type of setup I have may not be that common, there will be a fair few other people who have a system that's primarily designed for stereo high, with something like the Yamaha on the front; sadly I don't think there's a modern equivalent, but it provides amplification for the rear and centre speakers, together with decoding.

Sure, a modern AV receiver with HDMI all the way would be good, but I suspect I'd have to spend an awful lot of money for something as good as my Naim stereo amp, and stereo is what I'm listening to most of the time.

Nigel Whitfield.

Yes....

You can get the 5.1 audio from SACD via HDMI, or via the multichannel analogue outputs (which is how I have it hooked up)

ICQ chatted up by Russian billionaires

Nigel Whitfield.

Just ICQ

It's just ICQ numbers, because experience over the years of running the forum has shown that real users don't tend to enter an ICQ number when they register, whereas spammers often do.

And now, we have a note on the registration form that says "NB If you enter a website or ICQ no during registration, your account may be deleted as a suspected spammer"

The scripts that spammers use to automate forum signups, or the stupid people who do it for them, always miss that bit. Since the forum's for a product that's only usable in some countries, we also patched phpBB to require admin approval for people whose IP addresses don't appear to be in EU countries, OZ or NZ.

That got me a lovely ranting email from someone sulking because he had to be approved, telling me it was like "killing all babies, in case some of them turn out to be criminals."

Nigel Whitfield.

ICQ is useful ...

... I know that if I see someone put an ICQ number in the box when they register on a forum I run, they're a spammer.

Google Street View logs WiFi networks, Mac addresses

Nigel Whitfield.

MACs could be useful ...

If they really are gathering the details of all the MAC addresses in use, as opposed to just those of the access points, there are potential (though very likely pretty small) worries:

How securely will Google keep the data they collect? If you're using MAC filtering on your network, you might not appreciate someone gathering a list of all the MACs that you have, and then putting it in a big data centre somewhere.

While the MAC address wouldn't normally get outside the home network, if you're connecting to someone else's network, whether an office or a coffee shop, they're going to know your MAC address too.

That comes back to the first point; what are they doing with this information? If there's any way that someone else (including law enforcement) can determine that the laptop used a hotspot X on a certain date may be kept at address Y, that's more information than many people may feel happy giving out.

Get ready for the revolution: internet TVs

Nigel Whitfield.

Ease of use

Many RegHardware readers will probably find the features in these sets far too restricted for them, but some people might find a niche. For example, if the other half doesn't want the bedroom cluttered up with gadgets, a DLNA-compatible set means you could still have easy access to the porn collection. Pressing a button and selecting 'media server' to view the photos your clever partner's popped on the NAS is pretty simple to get to grips with.

Just as some people prefer a built in Freeview or Freesat tuner to what they feel as unnecessary wrestling with AV inputs and multiple remotes, even when that makes recording simple, so some will find even a limited built in set of functions simpler to get to grips with.

I would imagine that's a scenario familiar to any RegHardware reader who's tried to explain over the telephone to a less technically aware relative how to get the picture from their digibox to appear. Of course these aren't perfect, but there may well be some people for whom they'll do the job.

Analogue receivers are dirt cheap; it's probably easier to leave them in pan-european models, and some people out there will still be using devices connected via RF.

Nigel Whitfield.

New models

We do plan to look at newer models - I think it says that in the intro - and will look at all of those together, rather than comparing one brands latest model with the older ones from another.

Goodmans-Grundig intros identical Freeview HD set-tops

Nigel Whitfield.

Technology

It's the technology...

A standard def box for Freeview uses MPEG2 chips which have been around for years, and for which the development costs have probably been recouped many times over by now.

An HD box uses two new technologies - MPEG4 decoders, which have been around for a little while, but nowhere near as long as MPEG2, and DVB-T2 which is brand new, and only just available. It also mandates other things that aren't on SD boxes, like ethernet and HDMI, and some of these extra things require licence fees.

It's a bit like building a PC - if you insist on using the latest generation of Intel CPUs, it's going to cost you a lot more to put together a system, with all the support chips and so on, than if you create one around a processor that's getting a bit long in the tooth.

Brits blasé about 3D TV 'fad'

Nigel Whitfield.

Over your specs

All the glasses that I've seen at the various technology demos are big enough to fit over ordinary specs.

Of course, that's also why they end up looking like something that an early 70s futurist might have come up with.

Nigel Whitfield.

Extra specs

Even more annoying than the cost of the sets is that you'll typically only get two pairs of specs in the box, and noises from the various manufacturers suggest around £100 per pair.

That's a lot to expect your mates to fork out if they want to come round and watch the match in 3d.

Humax HD-Fox T2 Freeview HD receiver

Nigel Whitfield.

Ummm, no...

This particular box can't timeshift.

But the HD spec does specifically allow for recorders, and there have been quite a few announced over recent weeks (and a few on display at this morning's launch down at C4).

There are specific requirements, and more testing for recorders to get the FreeviewHD+ certification (and testing seems more rigorous in general for HD, perhaps because of experiences with poorly performing ultra-cheap kit in the past).

There will be recorders, including one from Humax, and they will be able to record HD. What's at issue so far is whether or not there will be the content protection included in the EPG data, which will allow broadcasters to prevent copying to other high definition media, such as Blu-ray; it's not a blanket ban on copying, but pretty much the same system that's already in place on Freesat.

Nigel Whitfield.

'Future services'

Ethernet is mandatory on all FreeviewHD boxes, and there have been suggestions that it could be used for iPlayer and similar in future, though the main marketing push at least initially is about other things.

It would be a big surprise if iPlayer doesn't arrive, but some of the manufacturers will also very likely use the ethernet port for their own services - and that may include pay services delivered by IPTV as well. At least one of the boxes on display at the launch today had a card slot, for instance, and comes from a company that's pretty well experienced in the IPTV and pay arenas.

At the technical launch (there's a link somewhere around here to my report of that), SeeSaw was also one of the things mentioned as being potentially able to take advantage of the ethernet connection in future.

Freeview HD launches, gets Channel 4

Nigel Whitfield.

Narrow beam

Narrow beam capacity is one issue for Channel 4 on Freesat, and indeed delayed the full ITV channel for a while, too.

The other, of course, is the persistent rumour that they receive some funding from a well known satellite broadcaster towards their HD service, and that that funding has strings attached. But in the absence of hard facts, it's just a rumour.

Nigel Whitfield.

Filters

Communal aerial systems aren't necessarily going to cause problems for HD, but in London and other areas where there's an infill transmitter, they may need adjustments.

Some of these systems have filters that only allow specific channels to pass, and will usually have been set up for the existing six muxes. Add a seventh, like the HD infills, and it's not going to reach the flats unless someone stumps up the cash for the engineers to tweak the filter setup.

In areas that have gone through DSO, that shouldn't be a problem, as the HD mux will be one of the six that should be passing through the communal system.

If you're having issues with other channels, then it might be caused by HD, but only if you're in an area where the HD signal from one transmitter is overlapping with the signal you're trying to pick up from elsewhere; but there aren't many places where that will happen, especially with a properly set up system.

It might be time to get your management co to look at how the distribution system is set up, and whether or not it needs some maintenance.

Nigel Whitfield.

HD Ready is not the same as HD

The TV you bought will be HD Ready, at best. And all HD Ready has ever meant is that the set can display a picture when connected to something else that outputs one.

The Freeview HD spec was only finalised last year - and for some time before then, it's been known that we'd be using a brand new technology in the UK (DVB-T2) for HD.

No one told you that a set you bought would be able to receive channels using a yet-to-be deployed technology; it still gets all the Freeview channels, broadcast using the specs that were available when you bought it.

As for Spain: some countries are broadcasting HD using DVB-T (the system we use for SD) together with MPEG4/H.264 encoding, and sets that understand that have been around for a couple of years.

However, even some countries where that technology has been deployed are thinking of moving to DVB-T2 in future, for the extra capacity it brings. People in that situation will have to buy twice for HD.

By launching HD with DVB-T2, the hope is that in the UK, people won't have to buy sets with one HD standard, only to change for a second a few years down the line.

BBC might pay for Tory broadband promises

Nigel Whitfield.

Gagging to invest

I can't see many companies rushing to provide incredibly fast broadband at affordable speeds in rural areas; looks a little unlikely. They'll just have to fob off the country folk with a resumption of fox hunting instead.

Even in the cities, a lot of firms will probably prefer to try and get a free (or wholesale price) ride on the back of BT, rather than actually go to the considerable cost of digging up streets, especially given other noises from political types, including tories, about ending the free-for-all that sees the same street dug up over and over by different companies. That laudable aim - to those of us who like our tarmac not to be serially molested - is at odd with ensuring there's little regulation to stop all these generous capitalists building out wonderful network. So, not much joined up thinking there.

Arguably, of course, you could blame Thatcher if you wanted, at least to a degree. All the buggering about with BT for the last 30 or so years stopped them rolling out faster networks when they wanted to, and now that the government wants them too do it for the national good, they find they'd also have to let other people reap the benefits of their investment, because apparently that's the right soft of interference in the market.

On the face of it, this seems like a pie in the sky policy that more or less amounts to "We'll promise something that sounds 50x better than labour, with less tax, and we'll take a bit of money from the nasty old BBC." Someone probably thought that was a nice triple whammy of tory goodness.

Eurocrats mandate maximum charge for data roaming

Nigel Whitfield.

Orange

Orange has just introduced various bundles - see a story here recently. The best value is the business roaming data bundle, at £7 per day (plus VAT) for up to 50Mb in most Europe. In theory, once it's added to your account, then that's all you'll pay for any day when you use data, up to the 50Mb, when the usual price applies. So if you use the whole amount, it's 14p/Mb, and as long as you use more than about 3Mb, you should be better off than usual.

That's the theory; however, it's such a new option that when I used it last month, their billing system completely screwed up and charged me for 51Mb of data over 3 days at the full price, instead of just £7 per day - around £110 plus VAT more than it should have done.

If you think you've found a good deal on mobile data, check your bills carefully...

Nigel Whitfield.

The channel

Obviously, it's the English Channel that causes us problems; the networks have to take special measures to make sure the packets don't get soggy on the way back here when we're roaming.

Judging by the price, each packet is lovingly conveyed across the channel by a golden cherub, on a silk cushion. And if it's not, I have no idea what we're paying for.

3D TVs to drop below £1000 in 2012

Nigel Whitfield.

All very nice ...

But in fact, a lot of the material that's going to be shown in HD (football and so on) isn't the best use of the technology. Sure, you can see depth, but it's still not entirely convincing, thanks to the 'playing card' effect.

And, while you may get two pairs of specs with your TV, if the broadcasts are - initially at least - going to be 'events' then mates will want to come round and watch with you. When the specs cost around £100 a pair, that's pretty expensive when half a dozen friends want to come and watch the match with you. The ones with 3D sets of their own can only bring them if they have the same brand.

Some of the figures quoted at Panasonic's recent event suggested 3D-capable sets would be in 40% of homes by 2015. Personally, I think that's pretty optimistic.

"For future use" is the official line; there's nothing I can add to that, I'm afraid.

Nigel Whitfield.

Well, anonymous...

Since you don't grace us with your name, I'm not sure why I bother replying... Someone (perhaps the same Coward) said there weren't HD boxes available; I merely pointed out that's wrong. They are on sale, albeit with limited distribution so far. But that's still not the same as "not on sale."

They're also available from HumaxDirect.co.uk complete with a charming flashing GIF that says "This is NOT a recorder." As far as I know, they went on sale the Monday after sales commenced in John Lewis Oxford St. If you're not pretty enough to hitch to London, I'm sure they'd be happy to deliver.

As for a review of the Humax, when RegHardware has played sufficiently, there'll be a review.

Nigel Whitfield.

Front panel

The front panel's not a thing of beauty, is it? The overall case design is perhaps an acquired taste.

As for the firmware issues: to be clear, it didn't crash, and Freesat recording was flawless, as long as two feeds were connected.

What we did see was one issue we weren't able to repeat, with a recording in non-freesat mode, which could possibly have been user error, though I suspect not. And on the library screen, there were times when the screen wasn't drawn correctly. So not enough to say it's flaky, but enough to raise a warning flag.

Nigel Whitfield.

Humax

The Humax Freeview HD box went on sale in John Lewis Oxford St last Saturday.

The S20 range only have FreeviewHD, no Freesat tuner.

Tories will force BT to open up ducts to rivals

Nigel Whitfield.

They're alright

Quite; rural areas will likely never been popular targets for private investment, so all the Tory talk of competitive pressure will come to naught. They'll score their cheap points by getting BT to do something they would have done anyway. A few people in nice houses will get faster broadband, and everyone in unattractive areas will be stuck in the same situation.

But, hey, at least we'll be saved £6 a year each, eh? If we'd used that to provide services to people in poor or rural areas, they'd probably only have looked at porn or something.

Confirmed: no iPad iBooks for Blighty

Nigel Whitfield.

Different DRM

Equally annoying is that though Apple is indeed using ePub, they're not using the Adobe DRM that almost every other ePub reading device uses for protected content, according to Adobe's blog at http://blogs.adobe.com/digitaleditions/

So, if you've bought books for, say, a Sony Reader, and decide you're tempted by the iPad, you won't be able to copy them over. You'll need to buy them again. And anything you buy from the Apple bookstore won't be usable on other ePub capable devices.

DRM is irksome, of course. But at least the ePub ecosystem was more or less unified. There's a danger that, far from strengthening it by putting ePub on a high profile device, Apple will achieve the opposite, splitting it into two camps - 'works with iPad' and 'works with everything else.'
