Design of a cooperative video/image multi-decoding system on a DSP

The convergence of telecommunication, information technology, and broadcasting, entails high-performance computing systems, and this has required TV manufacturers to move forward by employing DSPs. In this paper, we propose a cooperative video/image multi-decoding system that can make the most of the cost-effectiveness of a DSP by maximizing the DSP´s utilization rate. Since a multitasking algorithm is implemented without any hardware-specific assistance, the multi-decoding system can be executed on the majority of DSP platforms. The characteristics of the video and image decoders are reflected in the multi-decoding system in order to simultaneously decode video and image data as well as to guarantee the real-time processing of video. We verify the feasibility of the cooperative video/image multi-decoding system, and prove its efficiency in practical use.
