Baird is the word: Netflix's grandaddy gets bronze London landmark

Mage

Steam Punk

Marconi wagon mounted Wireless sets were sent to British forces for Boer War. They could in theory have sent radio fax (wired fax dates from 1851!) or 22 line Nipkow disk (like Baird TV) TV from South Africa to London. It would have needed some repeating stations, receiving on to recordable 78s (which may have existed) or Edison cylinders and retransmitted.

Some home recordings of Baird TV exist on 78s intended for home recording of Radio. The Baird tests started with AM radio after hours. Some of the USA AM stations had radio fax transmission in early 1930s after hours as well as the USA version of Baird TV.

Nothing unique or innovative about early Baird systems. The later ones overlapped superior RCA & EMI electronic TV.

Re: Lines

Visible and system lines are different.

405 approx 378

525 is 480 (hence VGA is progressive version of NTSC)

625 is 576

1125 can result as 1080. My Analogue CRT actually is 1125 lines to do 1920 x 1080 HD via VGA connector.

I think I mentioned 220, when actually last Baird was 240, but I don't know how many visible lines.

Re: Dead end: Philo Farnsworth

Philo Farnsworth's camera was electronic and also a dead end. Nor was it anything like an original concept or the first.

It's just the USA sees him in same light as UK sees Baird, a plucky underdog fighting the big corporation. Actually EMI was originally HMV, the UK branch of the Victor Talking Machine Co., bought by RCA, that had once had Marconi as a founder.

So EMI / RCA camera co-operation and also Marconi transmitters in UK is no surprise.

Double the resolution of a Farnsworth camera and the sensitivity is half. It was at the start 100s of times less sensitive than the Iconscope (Early RCA & EMI camera). The RCA/EMI system sensitivity was only much affected by frame rate as it stores the charge on the image between scans.

Philo Farnsworth's camera was doomed to never be usable at feasible lighting levels and even 220 lines (which Baird tried it at).

Re: His mechanical system, even enhanced, couldn't compete

Cathode Ray tube was Victorian, yet Dutch, not Baird was first to use it for display of Baird mechanically scanned TV.

The real problem, as Philo Farnsworth found, was the camera tube. Farnsworth's was very poor sensitivity because it didn't store charge. Baird bought some, but the film camera was better. The RCA / EMI system developed by Vladimir Zworykin.

1933 RCA Electronic camera (HD if on 9" display!)

http://www.tvcameramuseum.org/rca/1933cam/1933-p1.html

It was based on his design started at Westinghouse Electric in 1923

Baird was rubbish, chasing a dead end.

"In 1907, Russian scientist Boris Rosing used a CRT in the receiving end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen, which marked the first time that CRT technology was used for what is now known as television.[20] In 1897, J. J. Thomson, an English physicist, in his three famous experiments was able to deflect cathode rays, a fundamental function of the modern Cathode Ray Tube (CRT). The earliest version of the CRT was invented by the German physicist Karl Ferdinand Braun in 1897 and is also known as the Braun tube"

"In 1926, Hungarian engineer Kálmán Tihanyi designed a television system utilizing fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube"

Baird

He didn't invent modern TV. He started with a 22 line mechanical system, based on Victorian tech. The last version (using CRT display and film based cameras) was 220 lines.

RCA & EMI developed modern TV based on a 1905 idea. USA was 440 (later 525) and UK was 405. Operational from 1935.

On a 9" screen (typical) it was indeed HD compared to 1920 x 1080 on a 42" screen today.

WWII saw higher resolution used for Nazi rocket range CCTV.

1948 saw 625 line in Europe.

Baird was a showman and not even a real engineer. Eventually the Baird company paid him to sit at home. The film based near real time camera with built in processing and scanning was clever and used in early satellites as electronic cameras were too poor. The film processed on the satellite could be high resolution and the scanning of it could be sent back slower than real time per frame, as it was really still photography.

Did I read somewhere that Boeing was really developing a supersonic passenger aircraft (early concept had mad swing wings which make sense on a smaller plane), but abandoned it and transferred as much development as possible into the 747 development?

It's certainly been a successful design. What it needs is an upgrade to use a General Dynamics fusion engine.

AV is rubbish:

It regularly trashes OSes.

It slows machines

It has wrong default settings

Never up to date.

Gives false confidence, so users don't bother learning about basics.

Disable uPNP on router and PC, always use EXTERNAL firewall, turn off SSSD and all other stupid default services on Windows. No remote content in email. Use NoScript and whitelist and blacklist on each site you use (once per visit is usually enough). Don't install stupid toolbars. Always use custom install and untick extras. Don't download "free" versions of pay only software. Only use sensible sources for SW and codecs.

Disable Autorun on all devices.

All far more use than ANY AV.

Bookish hacker finds holes in Amazon, Apple, Google epub services

Mage
Silver badge

anyone can print and sell your books

This has always been true.

The Lord of the Rings was ripped off by a USA company.

Actually "anyone" can print and sell your books only in the sense that ANYONE can re-publish anyone's content of any kind, and DRM does not stop it. HD Video example: HDCP on HDMI and BD copy protection are extra costs to the consumer and HDCP creates problems. A pretty good pirate copy can be made by pointing HD camera at 42" HDTV in a dark room.

1) It's mostly a problem if you are already famous, then you have the resources to enforce your rights.

2) DRM is NOT the solution to copyright violation.

3) It's an overstated problem in terms of claimed lost revenue.

If you have a good story or great educational material, then publish, but NOT exclusive to Amazon. Also use Smashwords (who distribute to Apple iBook, Barnes&Nobel, FlipCart, Kobo etc). Read Mark Coker's free ebooks on the subject (Smashwords). There is also now Google's playstore.

Alert

I use MY kindle serial number on a Calibre plugin that removes DRM on books I BOUGHT, so I can read them on MY own KOBO.

So I don't want DRM enabled on the books I write and get published. Yes, "piracy" is wrong, but the amount of "lost sales" are grossly misrepresented.

I totally support copyright. I totally oppose abusive technology controls on how we consume content.

I'm still not any clearer though, on what the actual "flaws" found in this research actually do, or what they affect.

Clarification

Is this about DRM? DRM is unethical and should be illegal.

People or publishers can publish on Amazon or Smashwords, DRM free. I write and publish. I'm opposed to DRM and have never used it. I will though pursue anyone selling without giving me my royalty, or giving away copies, or plagiarising.

DRM doesn't even work anyway. It's contrary to the Berne Convention as it is still there when the copyright expires. Frequently blocks all fair use, or seriously limits it.

I also believe copyright should revert to author after 5 years and never be assigned to publisher for life of copyright, also 10 years after death is generous. The 70 years is a corporate land grab.

I remove DRM from anything I buy, but I don't even make copies for friends, only to other devices (like read Kindle on a Kobo) and/or backups.

Can we have clarification as to what these vulnerabilities enable?

Mine coat has a paperback and a Kobo. A commercial "pirate" can cut off binding, auto scan a book quickly, OCR, and even proof.

The problem is never ordinary individuals or downloaders but people uploading to "file sharing" sites and mostly commercial piracy.

When stuff is easily available, and reasonably priced (you listening Big 6 on eBooks or all CDs vs DVDs) then most people don't bother with piracy.

Apple eats itself as iPhone fatigue spreads

Innovation?

You can NOT "innovate" a particular product category for ever. It reaches maturity.

What about longer battery life, longer product life, more robust, and five SEPARATE connectors for charge, HDMI, data master, data slave and analogue audio/ear/mic. Then it could be used as a pocket sized dockable computer or a phone.

My ancient Sony Z1 nearly achieves this. My tablet is a FAIL. No way to power except on USB, previous model had a power jack. Can't connect USB slave devices and charge on USB, only USB host + charge. Only "casting" via wireless, which needs special TV HW and doesn't work with most apps. Previous tablet and old Z1 phone has a real HDMI port.

I hear there is an Apple Watch too, which is useless without an iPhone.

Apple sacrifice functionality nowadays for "marketing" appearance / "show room" cool, c.f. Waste bucket styled Mac, iPhone 7, Mac book pro touch, the x10 overpriced BT earbuds etc.

US Congress asks FCC to snuff out Google's TV landgrab

Mage

The arguement is irrelevant.

PCMCIA vs USB dongle misses the point.

1) It's possible to do cable or VOIP with no set box or dongle. My TV has DVB-C, 2 x DVBS-2, Wifi, Ethernet, DVB-T2 (USA models would be ISDB or whatever) and the PCMCIA style slot that can take a CAM for cable or satellite and a viewing card. It has dedicated USB HDD port (encrypts drive sadly even for FTA content. I have very small setbox. for HD TV DVB (which is more demanding than cable TV HW & SW), cost $50. I have an even cheaper HD Sat box, a little bigger. Ten years ago Motorola had a PVR setbox with HD, Cable, Ethernet VOIP(via external or using internal cable modem) and no need for a card. It could use DOCSIS to validate. It had the PCMCIA CAM slot too.

2) It's really about perceived control of content (anti-piracy) rather than forcing box rental (that's a means to an end).

3) Who gets to supply and bill the customer for content. That's why sky is going head to head with Global Liberty/Virgin and Netflix in UK by supplying not just by dish, but also by Broadband (even over virgin) via linear and non-liner VOIP streaming.

It's true you shouldn't have to rent the box. Sky actually gives away their boxes, but they are crippled (even the sat one) if you have no sub. The minimum contract with Sky ensures cost of install and box is covered.

For every tech success like ARM (most of which like the successful Sussex based Satellite building company are despite the Government) there are many the Government actively killed or created a a toxic environment for.

Pushing too hard.

Phones are getting too thin and fragile.

If the phone had been 2mm thicker this would never have happened.

1) Needing a bumper case is a design fail on the phone.

2) Not being able to sit with it in jeans pocket without it bending, unless it's designed to bend like an eraser or chew bar is a fail.

A larger phone needs to either be designed to be flexible or be even thicker. So ultimately the problem is Samsung's design. I imagine it will happen with other brands of phones unless they reduce the battery capacity.

IPV6 is a bad design

It takes no account of the real world, privacy is an afterthought kludge and has about zero ability to work with IP4.

I hope the IETF has been working on an IPv8 that interworks properly with IPv4 and that can be easily configured for privacy and security by default on home users "edge routers + firewall + modem + Wifi Airpoint devices.

Essentially we can only turn off IPv4 when EVERYONE is using IPv6, that's not realistic. Nor is the configuration of a home LAN other than for network specialists.

IP6 may be a wet dream for Google and IoT, but it's not fit for purpose for ordinary consumers or to allow seamless transition to IP6 from IP4.

One BEEELLION dollars: Apple sues Qualcomm, one of its chip designers

Mage
Silver badge

Re: Que ?

Very possible with Qualcomm. Without the "exclusive deal" the "mark" gets charged even more royalty (protection money?) often a percentage of entire product as well as surcharge on chip.

Even Intel only charges just for the chip (which no doubt partially explains the high cost), not a percentage on the entire product it's used in.

Qualcomm is to manufacturers what some exploitive software companies are to retail or business end users. I don't think they are liked by any manufacturer.

Business Model

Qualcomm's main business model is NOT selling chips, that's a means to an end. They licence.

Thus they lobby to have their IP in standards (which is why 3G was much less good than it could have been), buy up small companies and shutter them and buy larger ones and kill almost all products that don't have a per handset or per chip (or both) royalty.

They not only charge you for a chip, but want a slice of the product that uses it. They epitomise what's wrong with patents.

Of course they charge too much. Apple though should take care, most of Apple's patents shouldn't have been awarded, nor the excessive awards against those deemed to be breaking their patents, both "inventive" (= supposed real patents) and "design" (=Registered Design, a kind of copyright)

Or are Watson systems like a sale of a Adobe Creative Cloud or Oracle DB*, a trojan to ensure annual income from support, so it's losing money as it's still at the infiltrate stage (like inkjet printers in supermarkets which have to have only partially filled cartridges as they are so cheap).

However for food, basic household items, footwear, many clothes and large heavy things the local retail suppliers are actually cheaper and I'm more likely to get something uncrushed, fresh or fits.

If I'm sick I can even use the sort of service people had from 19th C. to 1960s, instant contact of retailer and home delivery (Tesco via Internet and various fast food via phone or internet).

Sad truth of Android

Many applications that shouldn't be, are communicating no-one knows what to no-one knows who. Eating your data allowance and privacy. Several apps inc. Kindle ereader put up error messages, even when you have not run them since last power on, when data is disabled.

Many versions of Android (even on things still being sold) don't allow any disabling of permissions. Many don't even properly inform you what is happening. Android TV on so called "smart" TVs is particularly bad.

* Only install Apps you REALLY REALLY need.

* Disable all Data when not explicitly wanting Internet

* Creatively use alternate versions of Apps that don't communicate (Calibre on Mac, Windows, Linux etc can take a remove DRM plug-in that uses your own Kindle serial number, then your /phone tablet can use any eReader app, even an ePub one.

Don't use eBooks using Adobe DRM. It contacts Adobe.
