“…In this paper, video buffer verifier (VBV) requirements are not taken into account, because the probability that a bitstream concatenated with segments does not meet the VBV requirements can be decreased by overlapped segment transcoding. In order to strictly guarantee the requirements, efficient methods for compressed domain video editing as proposed in [12] should be applied .…”

This paper describes a distributed video transcoding system that can simultaneously transcode an MPEG-2 video file into various video coding formats with different rates. The transcoder divides the MPEG-2 file into small segments along the time axis and transcodes them in parallel. Efficient video segment handling methods are proposed that minimize the inter-processor communication overhead and eliminate temporal discontinuities from the re-encoded video. We investigate how segment transcoding should be distributed to obtain the shortest total transcoding time. Experimental results show that implementing distributed transcoding on 10 PCs can decrease the total transcoding time by a factor of about 7 for single transcoding and by a factor of 9.5 for simultaneous three kinds of transcoding rates.

“…Another editing approach is compressed domain editing technique. For example, [1] proposes a method to concatenate MPEG segments while maintaining VBV condition. Picture-type conversion method in compressed domain for MPEG content trimming at arbitrary frame is explained in [2].…”

H.264/MPEG-4 AVC has become widely used in various applications and services because of its high coding efficiency. With the spread of H.264/MPEG-4 AVC contents, it has been strongly required to edit the H.264/MPEG-4 AVC coded contents with less computational complexity since the compression of H.264/MPEG-4 AVC requires far more processing power than other existing formats such as MPEG-4, MPEG-2. In this paper, we propose a fast frame-accurate editing method for H.264/MPEG-4 AVC contents. In the proposed method, we employed "Adaptive bit allocation and GOP-length modification" and "Re-quantization scheme with drift noise management" The proposed editing method can realize frame-accurate cut and splice editing regardless of picture coding types I, P, and B. In the experiment, we could also confirm the effectiveness of the proposed method in terms of processing power and the picture quality of the edited contents when compared with conventional editing.
