Actually it will not be long before we begin to see some of the advances in digital video processing showing up in consumer electronics. For example, here is a text on the technology to "fill in" detail:
Temporal resolution enhancement in compressed video sequences
The link requires Acrobat Reader as it is a pdf, but it is a very interesting look at things to come.
In a session with a projector company the other day we were discussing the current level of video processing for consumers compared to what is being developed. In addition to the temporal resolution (quantity of frames/sec) enhancement which will truly allow 24 fps to be converted to 30fps with 6 "developed" frames, or 60 fps they think ultimately, they also are working on simular processing to improve the spatical resolution (quantity of pixels per frame) as well. As soon as these formulas can be placed on chips, the new products can start to emerge. None of this was practicable with analog processing!
Tommorow looks like it could be a great day.
