Method and system for multiview distributed video coding with adaptive syndrome bit rate control

A system, comprising:

• multiple digital cameras, wherein each digital camera outputting associated captured video frames;
• a transmitter coupled to the multiple digital cameras, wherein the transmitter includes a multiview distributed video coding (MDVC) encoder and a syndrome bit rate control module, wherein the MDVC encoder includes predictive video encoders and WZ encoders for video frames coming from digital cameras in each group;
• and
• one or more receivers coupled to the transmitter, wherein the transmitter forms multiple groups, including multiple captured video frames coming from associated multiple digital cameras, based on a predetermined criteria, wherein the transmitter declares video frames coming from a predetermined number of the multiple digital cameras in each group as key video frames, wherein the transmitter declares video frames coming from remaining multiple digital cameras in each group as non-key video frames, wherein the transmitter encodes the key video frames in each group to obtain associated encoded bits using predictive video encoder, wherein the transmitter encodes the non-key video frames in each group to obtain associated syndrome bits using WZ encoder, wherein the syndrome bit rate control module decodes the encoded key video frames in each group using associated predictive video decoders, to obtain associated decoded bits and decodes the encoded non-key video frames in each group using associated WZ decoders and the decoded key video frames with iteratively increasing number of syndrome bits, to obtain associated decoded bits and CRC bits, wherein the syndrome bit rate control module determines an optimal number of syndrome bits of video frames in each non-key video frame in each group to be sent to the one or more receivers based on a successful WZ decoding, and wherein the transmitter sends encoded bits of key video frames and the determined optimal number of syndrome bits of each non-key video frame in each group to the one or more receivers.

A non-transitory computer-readable storage medium for multiview distributed video coding based on adaptive syndrome bit rate control, when executed by a computing device, cause the computing device to:

• form multiple groups, including multiple captured video frames coming from associated multiple digital cameras, based on a predetermined criteria by a transmitter;
• declare video frames coming from a predetermined number of the multiple digital cameras in each group as key video frames by the transmitter;
• declare video frames coming from remaining multiple digital cameras in each group as non-key video frames by the transmitter;
• encode the key video frames in each group to obtain associated encoded bits using predictive video encoding by the transmitter;
• encode the non-key video frames in each group to obtain associated syndrome bits using Wyner-Ziv (WZ) encoding by the transmitter, wherein the syndrome bits include parity bits and cyclic redundancy check (CRC) bits;
• decode the encoded key video frames in each group using predictive video decoding, to obtain associated decoded bits and decode the encoded non-key video frames in each group using WZ decoding and the decoded key video frames with iteratively increasing number of syndrome bits, to obtain associated decoded bits and the CRC bits by the transmitter;
• determine an optimal number of syndrome bits of video frames in each non-key video frame in each group to be sent to receivers based on a successful WZ decoding by the transmitter;
• and
• send encoded bits of key video frames and determined optimal number of syndrome bits of each non-key video frame in each group by the transmitter to multiple receivers.
