TV high-def for free

We got a new TV but no set-top box. It's fun to explain it to people.

"We watch high-definition TV programs."

"No, we don't pay for cable or a satellite"

"We use a technology where we get digital TV for free"

"No, there's no box, just a metal gizmo on the roof"

"We own the metal thing, there's no monthly fee"

"The technical term for the metal gizmo is 'rabbit ears'"

I've gone for 10 minutes before people realize what I'm talking about:

On a recent TV, you can watch high-definition digital TV signals sent over the air by existing TV stations for free.

I wonder how many people have a recent TV and just assume they have to pay someone to watch TV. Must be nice for cable and satellite companies! In February 2009 the regular analog TV stations will disappear, leaving only the digital signals, but despite all the public service announcements people don't understand broadcast TV will continue to be free.

Each TV station has one to five digital TV channels. The first tends to be their regular analog broadcast in better quality. The others are all over the place. Fox's Channel 2-2 shows LATV, which is cheesy Latin music videos along with a scroll of incoherent text messages. The CBS and NBC affiliates rebroadcast their nightly news over and over. PBS has a world channel, an all-British TV channel, and a kids channel. So it's almost like having basic cable with 57 channels (and nothin' on – Bruce Springsteen).

Each station must be transmitting a coded representation of the day's schedule, because you can find out more info about what's on each digital channel and see what's on later in the day. But before you can scroll through the day's programming for all channels, you have to tune in to each channel to receive this. So it's sort of like a cable box's interactive program guide.

Almost, sort-of. But it beats paying a company money every month for the rest of your life.

electronics: LCD TV

I wrote way back in April

Meanwhile, I've only 10 days to buy a TV, a surround system, a PS3, and umpteen cables, to play GTA IV.

Indeed, on the day of the Grand Theft Auto IV midnight launch I finally got an LCD TV and disconnected the Sony Trinitron.I had held off for years watching the never-ending procession of must-have features that has kept the price of a high-end TV above $3000: 720p, 1080i, 1080p, CCFL backlight, LED backlight, low millisecond response, DVI input, HDMI input, 120 Hz refresh, OLED...

Actually buying one was straightforward: Best Buy offered a reasonable Samsung LN40A550 TV with a PS3 and installation for $1599, so I bought the package without bothering to go through the heck of comparing TVs. You don't need 1080 resolution at the distance we sit from the TV, but they didn't have a similar deal on a 720p TV. Best Buy agreed to swap the free installation for free TV calibration, but it took two salesmen 30 minutes of wrestling with their sales computer to print the receipt. I think that wore Chris and Glenn out: I was prepared to fight the hard sell of a service contract and overpriced cables, but it never happened.

Set up was easy, just plug in and go. The TV works fine, no bad pixels. I don't even know which of those fancy features it has (I'm a audiophile, not videophile). The picture looked fine from the start and looks slightly better (softer and warmer) after the Geek Squad finally scheduled a guy to calibrate the TV.

I briefly considered the surround sound part. Best Buy had two stacks of surround-sound receivers, each with a hundred connectors on the back but obviously lightweight construction, and none hooked up to speakers. If and when I ever get surround sound I'll get Magnepan surrounds and center speaker, probably with a semi-audiophile receiver from Integra, NAD, or Rotel.

Plugging in a laptop VGA cable gives you a fantastic 1080x1920 desktop with only the slightest ghosting. So I should be copyright infringing TV shows and movies and surfing YouTube on the laptop while hooked up to the TV. But even though the TV is a computer (Samsung offers Linux source code for it) and a set-top box is another computer, watching TV in the living room doesn't fit with a PC.

web: life of a Beijing pirate is hard, yarrrr

Even with an outside high-def antenna from AntennaPros, I can't tune in to over-the-air NBC ever since the station moved to San Jose. Curse you, hilly geography!

So no Olympics (or Heroes, or Tonight Show) for me. Yet the opening ceremonies are meant to be the greatest ever!

Ahh, but I hear there be “pirates” a-sailing the IntarWub tubes who make TV booty available to landlubbers. (Though what, exactly, is the piracy in taking something freely broadcast over the air to anyone who can receive it and making it available to others?)

I knew from my experience trying to grab early Joanna Newsom albums how difficult this would be.

• Google for Olympics 2008 opening ceremony torrent
• Update to latest BitTorrent program just to be safe.
• Download the small .torrent file, it opens in BitTorrent.
• My download speed is close to zero, so I reconfigure my router's port forwarding for my current IP address
• It starts downloading, dozens of computers world-wide handing me pieces!
• The torrent contains two files
  1. Beijing.Summer.Olympics.2008.Torch.and.Fireworks.BBC-HD.1080p.H.264.AC3.2.0.mkv (1.12 GB)
  2. Olympic Opening Ceremony [2008] (minus athletes entering).avi (598 MB)
  The first file downloads in a few hours, the second file never gets started.
• I watch the first file, in Media Player Classic. It's insanely high resolution but choppy as hell and it's only the five minute climax of the guy running around the scroll!
• Search again, find torrents on The Pirate Bay yarrr, arrrr, together with user reviews. Everyone wants a torrent without commercials and without the irritating commentators, nobody has one. For a bunch of freeloaders we sure are demanding.
• I settle on Beijing.Olympics.2008.Opening.Ceremony.720p.HDTV.x264-ORENJi, not-quite-so high-def
• download the .torrent and BitTorrent starts grabbing pieces of the file.
• It's 5 gigabytes, 53 files 95.3 MB each!
• The next morning it's all downloaded, but my BitTorrent program continues to offer bits of the file to other users. Arrr, they're not just pirates, they be Communist pirates sharing amongst themselves!
• Try to play the first file, orenji-x264-beijing.olympics.2008.opening.ceremony.720p.hdtv.x264-orenji.r00, but no luck: Windows Media Player, Media Player Classic, and VLC Player all can't play it. Media Player Classic knows a few details about it like the encoding rate, but there's no sound or video in any of them.
• Google for x264 "Media Player Classic", figure out it's a variant of H264 video compression, this forum post tells me I need ffdshow plus Haali Matroska Splitter
• I download and install those decoder packs, adding to the half-dozen media-playing bits and pieces on my computer. Both have dozens of setup options for which formats they should own and mostly incomprehensible video settings.
• Again, try to play that first 95MB file, nothing doing.
• I look more closely, there's also a orenji-x264-beijing.olympics.2008.opening.ceremony.720p.hdtv.x264-orenji.rar file, which sounds like a compressed file.
• Try opening this, 7-Zip volunteers to open it.
• Indeed, it's a compressed file, so I extract the original file blahblah.mkv
• 15 minutes later, it's still extracting.
• The original file is 5,157,477 kB!! 5GB! And there are 50 of these! I'll need to dedicate a hard drive just for this one TV program!

And even with these encoders, the sound is staticky and choppy; I guess not only is my disk too small, but my Athlon 64 3000 with 1GB of RAM isn't powerful enough. The insane file sizes and CPU demands demonstrate that high-quality computer video has barely entered the realm of possibility, unlike computer audio where any $40 cellphone or $2 birthday card can play music.

Yet clearly there are many people who have mastered this hassle and happily grab a daily buffet of free TV shows and movies from the pirates' distributed digital treasure chest.

stuff: low-quality Hi-Def at Best Buy

Criticizing Best Buy is like shooting fish in a barrel, but their sales effort is so poor they have to hear it over and over.

I want a new TV. It's in a bright room so I want LCD rather than plasma. I don't want to block the fabulous view so 46" is my limit. According to this fine explanation, at my 10-foot viewing distance I won't be able to discern the finer resolution of a 1080p set (1920x1080), so a 720p set (usually 1366x768) is sufficient.

So I go to Best Buy. The TVs are arranged at random, with plasmas next to LCDs. Most are running concert video footage that's 480p at best. A few are playing DVDs. Some have the sharpness control set so high that hair and fur sparkles. None of the sets I want to compare are next to each other. So picture quality comparisons are simply impossible. They are selling a Samsung true 1080p TV for less than the Samsung 720p TV that the salesman recommends to me, and there's no indication of why the lower resolution TV costs more.

Later I go to Best Buy's web site and try to compare. They have a Sony KDL-46S2000 for $1,979.99 and a Sony KDL-46S2010 for $2,519.99. There is absolutely no difference between them in Best Buy's online comparator, and the individual product page for the cheaper set lists many more features. Each TV in the comparator has several features that no other set has, e.g. for "Brightness" the Samsung has "500 cd/m²" and the Sony has nothing, while for "Remote control type" the Sony has "Standard" and the Samsung is blank. ??!

I could read the Plasma and LCD Flat-Panel Displays AVS Forum to get feedback from some impassioned expert users, but most product threads have 400 replies and some have over 2,500 replies!
