LOW POWER SOFTWARE HEVC DECODER DEMO FOR MOBILE DEVICES

Abstract : Video on mobile devices is a must-have feature with the prominence of new services and applications using video like streaming or conferencing. By improving the compression performance by a factor of two with a similar quality, the new video standard High Efficiency Video Coding (HEVC) is an appealing technology for service providers. Besides, with the recent progress of Systems-on-Chip (SoC) for mobile devices, software video decoders is now a reality. On top of providing a high flexibility of implementation, it offers a mean to a fast HEVC deployment on the existing devices without waiting for hardware compatible solutions. Finally, the challenge is also to provide power efficient design to fit with the compelling demand for long battery life on mobile devices. We present here a practical setup demonstrating that the new HEVC standard can be implemented on on-the-market devices where hardwired decoding is not possible. We also show a subjective evaluation of the low power HEVC de-coder within the scope of MPEG Green Metadata. It shows that power savings close to 7% can be achieved on a typical smartphone including the rendering on the screen.
