B-frame Transcoding in H.264 to MPEG-2 Transcoders
نویسندگان
چکیده
In this paper we review fast transcoding techniques for H.264/MPEG-2 B pictures. B pictures are a bidirectional prediction mode used by the H.264/AVC and MPEG-2 video compression standards. B pictures allow motion estimation (ME) to be performed using both backward and forward reference frames. This type of inter-prediction is highly effective but also highly complex making reduced complexity methods highly desirable for the transcoding process. Results show an application of reduced complexity techniques may reduce overall transcoding time by up to 70%.

FIMDA: A Fast Intra-frame Mode Decision Algorithm for MPEG-2/H.264 Transcoding
The H.264 video compression standard provides tools for coding improvements of at least 2 dB, in terms of PSNR, and at least 50% in bit rate savings as compared with MPEG-2 video compression standard. It is expected that the H.264/MPEG-4 AVC will take over the digital video market, replacing the use of MPEG-2 in most digital video applications. The complete migration to the new video-coding alg...
متن کاملDirect Transcoding of AVC/H.264 Bitstreams for Bitrate Reduction with Minimized Video Quality Losses
The paper deals with transcoding of AVC/H.264 bitstreams where some bitrate reduction is required. For single-layer bitstreams, often Cascaded Pixel Domain Transcoders (CPDT) are used unaware of the fact that such transcoders are complex and very inefficient when used for bitrate reduction not exceeding 30% of the primary bitrate. In order to avoid these disadvantages, the authors propose struc...
متن کاملHeterogeneous Transcoding: MPEG-2 to H.264/AVC
The wide deployment of MPEG-2 video and the extra benefits of the features introduced by the H.264/AVC standard, create a strong need for video transcoding between these standards. In this paper the typical problems for video transcoding between MPEG-2 and H.264/AVC are discussed. One of the most basic problems is the difference between the 8x8 Discrete Cosine Transform as used by MPEG-2, and t...
متن کاملH.264/AVC to MPEG-2 Video Transcoding Architecture
Video transcoding is assuming an important role in modern video communication systems in order to allow interoperability between different equipment and standards. So far most effort has been spent in transcoding from older standards to the most recent ones. However, as new standards reach higher levels of compression efficiency, the diversity of bitstream formats also increases. In this paper ...
متن کاملComplexity Reduction Tools for MPEG-2 to H.264 Video Transcoding
The wide deployment of MPEG-2 video for digital video applications today and the expected use of the recently standardized H.264 video create a strong need for video transcoding between these formats. One of the key problems in video transcoding is complexity reduction. In this paper we present tools to enable low complexity transcoding of MPEG-2 video to the H.264 format. The proposed transcod...
