- W188561649 abstract "Video transcoding from Distributed Video Coding (DVC) to H.264/AVC provides a suitable framework for Mobile-to-Mobile video communications because both the transmitter and the receptor keep low complexity constraints during video compression and decompression processes. DVC is formed by simpler encoders jointly with a high complex decoder, a scheme counterposed to H.264/AVC. This framework thus moves the high complex processes to the transcoder, which has more resources. For this reason, this work is focused on reducing the complexity of the transcoder. With this aim, on the one hand the first transcoding stage is improved through a multicore processor, which executes the DVC decoding in a parallel way. On the other hand, the second stage uses MVs generated during the DVC decoding to reduce the motion estimation complexity of H.264/AVC encoding. As a result, an efficient paradigm is provided to support mobile-to-mobile video communications which reduces the time spent by up to 77% without significant rate-distortion loss." @default.
