Abstract
In practical multimedia systems, the content of coded video streams often needs to be re-edited at the nodes of transmitting networks. For example, logo insertion is always required for copyright protection at different local transmitting nodes. This kind of video stream editing is denoted as video content editing transcoding (VCET) in this paper. Though some techniques have been suggested for VCET, these methods cannot meet the requirement of dynamic transmitting bandwidth in practical applications. In this paper, we proposed an interface macroblock-based transcoding scheme for VCET, which can reuse the variable length codes of the original video streams as much as possible to achieve the best VCET quality. In order to ensure that the edited video streams can be transmitted by the original bandwidth, we also proposed a rate control algorithm for VCET, which can accurately control the bitrate of edited video streams according to the frame level coding bits of the original video streams. Experimental results showed that the proposed scheme achieved substantially better results in bitrate accuracy, computational complexities, and video quality than many other existing schemes.
