Abstract:
1. A method for adaptive syndrome bit rate control in multiview distributed video coding (MDVC), comprising: forming multiple groups, including multiple captured video frames coming from associated multiple digital cameras, based on predetermined criteria by a transmitter; declaring video frames coming from a predetermined number of the multiple digital cameras in each group as key video frames by the transmitter; declaring video frames coming from remaining multiple digital cameras in each group as non-key video frames by the transmitter; encoding the key video frames in each group to obtain associated encoded bits using predictive video encoding by the transmitter; encoding 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; decoding the encoded key video frames in each group using predictive video decoding, to obtain associated decoded bits and decoding 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; determining 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 sending 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.
