TV as we've known it has barely a year left to live. On Feb. 17, 2009, the analog broadcasts that have taken the networks into American homes for decades will end, replaced by a stream of digital bits that carry video and audio more efficiently and with higher quality.

WARNING! Don't go rushing out to buy a new bargain-priced analog TV set. You will not be able to receive over-the-air television programming on it after February 2009. Analog TVs will then be technically obsolete. Only new digital sets will be able to pull signals from the airways.

As you may recall from my last entry, I exchanged my cable box from a Scientific Atlanta 8000HD to a Scientific Atlanta 8300HD.  The latter, new box continues to output a signal from the cable connection even if I have it in HDTV mode.  It probably also continues to output AVI and S-Video.  This finally opened up a way for me to use my cable box with a MythTV box.   Thanks to a serious (and mysterious) spinal injury (I say mysterious because I haven't figured out how I did the damage), I can only work on the project for a half hour at a time, at most.  I have discovered some interesting things in those short segments.

Ladies and gentlemen, boys and girls... It's with much anticipation that I say this. I have a new product that may be familiar to those of you who used Radio 8, and in other ways may be completely new.  The idea is simple.  There's a convergence between big screen high-definition televisions, and photography as an Internet based activity. The purpose of this product is to smooth that convergence, to make it easy to set up a connection between the Internet and your television. To allow photography to come into your living room in new, powerful and easy ways. Think of it as the networked living room and you'll understand the vision. Some of the work I've done is technical, some is user interface, and some is working with media organizations to try to create a comfort level, or at least a spirit of Let's Give This A Try. In the latter case, it's much like working with the NY Times to get their news headlines and summaries to flow through Radio's RSS aggregator in 2002. Only this time we're working with photographs, and we think, the best news photographers in the world. And the pictures are beautifully high-def, they look really great when displayed on LCD and plasma screens. I use it with my 52-inch Samsung and 46-inch Sony. Of course what looks great on a wall, also looks great on a 15-inch Macbook or 24-inch iMac.   And while we connect those pros with your TV, it's equally important that we connect your friends and families too. One of the early testers found the pictures that Doc Searls uploads to Flickr a great revelation. Me too. That's because Doc is not only a great photographer, he's also a great story-teller. I find that I can follow the lives of far more friends visually than I can through text messages (which I love to do too!). Viewing great photos on bigscreen TVs, desktops and laptops -- that's one focus, but not the only one.  I wanted to provide a complete two-way tool for people who love Flickr, as I do.  Why Flickr? Well, they've got this great thing called an API. It makes it possible for people like me to make software that runs on a desktop computer that does things like automatically backing up your new photos every night, and providing a drop-folder on your desktop for quick uploads. (It understands tags too, it's incredibly simple.) We also made it easy to post pictures you like to Twitter. Why Twitter? It's that API thing again. They made it easy for us to love them. I wish more network service developers understood how powerful this outstretched hand is.  But that's not all! Not by a long shot. The reason all this will be so familiar to Radio 8 users is that it builds on the same engine, the one that was released as open source in 2004. So I've been working on other tools to drop into this base platform and once we have a good-sized base of people using it for "really simple photos" on the desktop, there will be other tools. And because it's an open platform, other developers can do the same. Not saying they will, but they can.  Anyway, I'm in the last stages, preparing the download site, and a FAQ, and tweaking the installer. One caveat, the first beta release is Mac only. That's because I'm doing all my work on the Mac, and this is a one-man show. Later we will work it out for Windows too, and with a bit more work and a bit more luck, for Linux.  It should be ready before the sun goes down today.

Digital, high-definition television can be a complex enough business in its own right. But the shift from analog to digital now also means a shift from fat to flat. -The Washington Post

Christopher Breen  takes us on a tour of Apple TV that begins with downloading the software update and ends with the big questionââHowâs it look?â To which Breen responds, âDarned good.â After renting Live Free or Die Hard. Breen reports that â the picture is great on my 42-inch Panasonic plasma display. With a digital audio cable connected to my AV receiver the movie caused the receiverâs 5.1 Dolby Digital Audio light to glow and the resulting sound was bigger than anything Iâve heard come out of the box previously.â

I have good news, bad news, and worse news.  The good news is that I managed to get MythTV working well enough that it now plays standard definition channels better than the cable box alone, even though it's getting its signal from the cable output of the cable box.  I get this benefit because MythTV allows me to tweak various parameters that you can't change on the cable box.   The bad news is that high definition channels still look worse through MythTV than they do if I watch then directly from the cable box.  I don't expect to solve this problem. The cable box may be able to handle HDTV itself, but it outputs a digital signal in 480p, which is basically standard definition. The fact that I have two HDTV-capable tuner cards does me little good.  Here's the worse news. I had to learn way too much to get this far.
