Multi Bearer Channel Resource Allocation for Optimised Transmission of Video Objects
This paper presents a novel channel optimisation scheme that enhances the quality of object based video, transmitted over a fixed bandwidth channel. The optimisation methodology is based on an accurate modelling of video packet distortion at the encoder. Video packets are ranked according to their expected distortion and are then mapped to one of a number of different priority radio bearers. In the proposed scheme the video compression technique uses motion compensated prediction and video frames are split into a number of video packets. The algorithm performance is demonstrated for object based MPEG-4 video transmission over a UMTS/FDD system. The results demonstrate that the performance gain achieved with the proposed scheme can reach 2 dB, compared with the equal error protection scheme for video transmission over a fixed bandwidth channel.
