Gavin, Snooping around the messages and found one which struck a chord. I have been tinkering as a more than interested user with both full motion video and audiographics t/c for about 18 months and in answer to you queries, preference would be for: 1. Resolution to say VGA standards, min 32K colour or better, min 25 frames/sec refresh rate all compressed to nothing, multiplexed with data and audio carriers and pushed down the most economic single channel ISDN codecs possible. 2. However in the real world, experience suggests that lip sync seems to be more important than absolute hi-definition in most circumstances. Hence more frames per sec refresh rate would be preferred to gains in image definition . 3. Colour again seems to give better recogonition qualities than B/W images given the same levels of signal delivery – even though the absolute definition and image quality of B/W would be higher. Is your R&D in this area for your own products or for one of the known 20 or so suppliers? Kind regards.
