Spatial resolution reduction of compressed video is highly desirable in video transcoding. Many studies have addressed this problem, but they either cause drift error or have high computation complexity. A new spatial downsampling algorithm for DCT-Domain video transcoder is proposed in this paper, in which L??M sub-blocks of N??N are combined into a L??N rows and M??N columns blocks in DCT-Domain...
Motivated by the wide adoption of H.264 and the demand of universal multimedia data access over wireless network , this paper studies H.264 homogeneous video transcoding with spatial resolution conversion. Firstly , we propose a fast video transcoder ,working entirely in the DCT-domain,to convert high quality H.264 bitstream into low bit rate stream with low spatial resolution for wireless video access...
