Noise-resistant video codec of 9600 bps
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.
Examples of restored images
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 of the coded files.
