| Lab squeezes HDTV into standard TV channel |

| From the article: "Los Alamos National Laboratory has announced an encoding algorithm that squeezes a high-definition television signal into the existing 6-MHz bands already allocated to TV broadcasters. Existing analog TVs can receive the broadcast as usual, but HDTVs will be able to decode the embedded digital information for rendering on progressively scanned, 1,280- x 720-pixel displays." |
| This could make the eventual transition to HDTV considerably easier. |

| Another HDTV rant by jwales 2:36:31 pm mst / 6 March 2001 / # 2 |
| As for me, I don't want HDTV *period*. I can't think of a more useless thing to do with bandwidth than to cram that much extra information about television programs down the pipe. I don't think consumers care very much, either. Existing picture quality is not a problem.

| Does this really seem like a good idea? Enough confusion already exists in the HDTV space without adding yet another layer of complexity and ‘standards warfare’ to the mix. My favorite quote is: "When you flip back and forth between the original and our encoded HDTV signal, you can barely tell the difference” THEN WHAT’S THE POINT! I want HDTV to be high-def! A solution to a problem that no one asked for! |

| The sooner the content providers can get us all on HDTV, the sooner they can implement the copy protection schemes that will be built into the signal. Forced view advertising, no more recording broadcasts who's signals are marked copy-protected, and eventually some type of credit/pay-per-view scheme are all in our distant future for television viewing, I fear. Do you really think they're all in this to provide us all with higher-quality viewing? Nah, they're anxious for this because they can implement encryption and copy-protection right in the HDTV signal. The wait for the actual HDTV sets to become affordable and for everyone to buy them will be incredibly long. Better for them to just work out a way for existing TV's to receive the signal as well. Remember these days, folks. |
