Parallel Implementation of Multi-View Video Decoder for Reduction in Power Consumption

Free registration required

Executive Summary

Mobile platform based multi view video applications have gained significant attention due to increase in processing power of mobile processors. Significant performance improvements have been reported by using H.264/AVC based video encoding-decoding procedures. Multi-View Coding (MVC) is an extension of H.264/AVC scheme employed for high performance compression of multi view videos. The increase in spatial/temporal information has increased the difficulties in real-time decoding. In existing implementations, multi-processor based architectures have been employed to achieve real-time processing in H.264/AVC. In this paper, a parallel MVC decoding scheme is presented. The implementation is based on pipelined architecture of Cortex-A8 processor and Graphics Processing Unit (GPU). The decoding procedure is divided into block based and pixel based operations.
