Abstract
This paper presents a method for transcoding from H.264 to MPEG-2. This process is divided into two parts: Intra frame transcoding and inter frame transcoding. For intra frame transcoding the brute force method of encoding and decoding in H.264 and re encoding in MPEG-2 is applied. In inter frame transcoding the motion vector information from the H.264 decoding stage is reused in the MPEG-2 encoding stage leading to significant savings in the transcoding time with very less degradation in terms of PSNR when compared to an MPEG-2 encoded decoded sequence.
