Private Tour: How Mobile TV Gets Made : Transcoding Each Channel
|

Digital media uses less bandwidth than analog to encode the same information, but that's not the only reason that MediaFLO can fit 20 video channels and 10 audio channels into a single UHF channel. MediaFLO dynamically allocates bandwidth to each channel on the fly as it’s transcoded so that video only gets the bandwidth it needs. The audio channels like EPSN Radio get static bandwidth, but the video channels have variable bandwidth depending on how much detail is in the image and how fast it’s changing. “A sports show, like a basketball game with a lot of action on screen gets more bits than a newscaster that's basically a talking head,” Wallace said. This chart shows the real-time bit rate allocated to the video and audio bandwidth for each channel: FOX, MTV, Fox News, and one of the preview channels are getting most of the bandwidth at this time, followed by the PIX movie channel.

What happened to the "anti-tv" crowd that was doing so well not too long ago? The last thing I need is another way to watch more stupid programs and dumb commercials!!
