DUCATI SYSTEM ANALYSER FOR OPTIMIZING PEER TO PEER VIDEO CHAT IN OMAP ENABLED HIGH END MULTIMEDIA MOBILE PHONES

Abstract

OMAP developed by Texas Instruments is a category of proprietary system on chips (SoCs) for portable and mobile multimedia applications. OMAP4 is the fourth generation SOC that is used in many of today‟s high performance and low power multimedia devices- which include smart phones, tablets, video conferencing solutions and other consumer products. OMAP4 enables true High Definition multimedia (1080p), very high performance graphics and yet offers a low power advantage over other SoCs. To name a few use cases - today's devices are capable of playing 1080p content, allow streaming of high definition content, capture images with high resolution cameras greater than 8MPixel, and also support high definition video chat in peer to peer networks up to resolutions of 720p. The advent of all these multimedia services has given rise to serious challenges in terms of battery usage (Power) and performance. The most complex of the above all use cases is the video chat, in which device is involved in performing a video decode of the stream coming in from the remote, and simultaneously the camera is operational on the near end and it is performing a video encode to send the compressed bit stream to the remote end. To build an optimized solution, we need to analyse several parameters in the system and continuously work vii Ducati System Analyser towards understanding the intricacies. With a thorough study of the current design of the Video Chat application, I developed and designed the Ducati System Analyser which will help developers to actually see trade-offs between all these parameters so they can configure chat application and find out more optimal configurations.
