Common description
Noise-resistant video codec (NRVC) with bit-rate up to
9600 bits per second intended for usage in discrete channels with coefficients
of bit errors (BER - bit error rate) 3-4 %. NRVC it built on the basis
of modified algorithm H.263 and the block of channel encoding with usage
of the error correcting codes.
The video codec intended for encoding a moving image.
Input video format is SubQCIF YUV 4:2:0 (picture resolution 128x96 pixels
is applied at 12 bits on each sample) with frame rate 1-3 fps.
To estimate quality of restoration it is possible on
files represented below.
Usage NRVC: Transmission of low-frame-rate digital video
on low-speed communication channels to the subject noises;
NRVC 9600 bps is implemented as C models for PC. Real-time
implementation on the base of TMS320C6000 DSP families will be done in
near future. Please ask for its parameters.

On following videos to files you can estimate quality of restoration
of the image by transfer on the channel with a noise:
The note: preliminary it is necessary to download the player
