Unequal decoding power allocation for efficient video transmission

Abstract

We present an unequal decoding power allocation (UDPA) approach for minimization of the receiver power consumption subject to a given quality of service (QoS), by exploiting data partitioning and turbo decoding. We assign unequal decoding power of forward error correction (FEC) to data partitions with different priority by jointly considering the source coding, channel coding and receiver power consumption. The proposed scheme is applied to H.264 video over additive white Gaussion noise (AWGN) channel, and achieves excellent tradeoff between video delivery quality and power consumption, and yields significant power saving compared with the conventional equal decoding power allocation (EDPA) approach in wireless video transmission.
