Paper Abstract:
|
Modern home networks include devices of different types and brands with software and hardware that enables discovery, control, and content streaming. This is possible because modern devices implement a standard known as DLNA. Unfortunately, the video streaming experiences sometimes fail because of format/profile incompatibilities. Transcoding the video stream to a common format/profile in real time can solve the problem, but it is an expensive operation for the type of mobile computing devices that users have at home (phones, tablets, laptops). This paper discusses a methodology for distributing video transcoding tasks among multiple slow transcoders towards real-time transcoding operations. The proposed task distribution procedure is designed to be compatible with current home network architectures based on DLNA. The paper demonstrates that the proposed procedures can be optimized so that a group of concurrent slow transcoders approximate the performance of a real-time transcoder. |
