JOINT SOURCE/CHANNEL CODING FOR MULTIPLE VIDEO SEQUENCES WITH JPEG2000

With the rapid advances in channel spectrum utilization and data compression techniques, many communication channels are now capable of delivering several compressed images and video se-quences concurrently. There has been a lot of research in joint source/channel coding (JSCC) di-rected towards allocating resources between source and channel coders to improve overall perfor-mance. However, most existing JSCC schemes in the literature only consider the coding of one image or video sequence. Meanwhile, the problem of multiplexing multiple video sequences has also been studied. However, these schemes fail to take channel coding into account. Motion JPEG2000 (MJP2) is an extension of JPEG2000 for intra-frame based video coding. It can provide competitive performance to motion compensation based video coding standards in applications requiring high quality or high resolution. In addition, it can provide highly scalable bitstreams, which is desirable for applications such as HDTV digital broadcast [1]. In [2], joint source/channel coding was considered for transmission of multiple images sharing a common channel. Given a transmission channel and a total bit rate, rate-distortion diversity of different images was exploited to give multiplexing gains (in terms of MSE), in addition to the conventional unequal error protection (UEP) gains. In this work, we extend the methods of [2
