To resolve the problems of EAGB and in some way also for Wgnr, the Mpeg4/h.264 codec, and media format and set-top box solution comes easy after a few months of pondering about the ultimate solution.

First, there is no silver bullet by technology, to use new codecs for universal applications. Mpeg2 cameras should use mpeg2 set-top boxes; and analog large screens TVs do its own zoom and increase pixels from the base ntsc or pal pixels. this will immediately remove any mpeg2 to Mpeg4 conversion blue screens. And it is not much of a problem; since HD format actually uses less pixels than ntsc resolution because the wide screen uses less vertical pixels.

Movies of wide screen and technical colors, uses less vertical pixels on ntsc TV also. No conversion from Mpeg1 to Mpeg4 is necessary. Mpeg1 in set-top box should be available. Large analog TV screen has to zoom to have more pixels, anyway.

Broadcasting stations has to have Mpeg4/h.264 cameras to broadcast to Mpeg4/h.264 set-top box to display on analog TV anyway? Fox is converting Mpeg4/h.264 codes from their cameras and broadcasting in ntsc analog signals without faults.

So, this will be satisfactory for set-top boxes to go forward. then motion jpeg type of Mpeg4/h.264 can be tested for conversion integrity and performance to do Mpeg2 to Mpeg4 conversion on the fly. But my sense is that they will not make the grade at the end of this year.

We have to make a go with Mpeg1 and Mpeg2 on analog TV with existing set-top boxes, and use Mpeg4 cameras at the broadcsting stations for Mpeg4 set-top boxes. Remember, the display is still analog TV not digital monitors? eventually codec conversion will be done pixel by pixel to be accurate. motion jpeg super imposed on static jpeg background may be the fall back Mpeg4/h.264 codec technology to avoid blue screens of digital faults.
