| Product Profile MB86H52 MPEG-2 HL to H.264 HD Transcoder Introduction The Fujitsu MB86H52 can compress full HD (1920dot x 1080line) MPEG-2 video data to H.264 data. The new chip, the MB86H52, is a transcoder that can compress MPEG-2 video to less than half the data size. The transcoder functionality is based on the video processing technology of the presently shipping full HD H.264 CODEC (Encode / Decode) LSI product, MB86H51. Utilizing proprietary high quality video technology developed by Fujitsu Laboratories, the quality of the inputted MPEG-2 video data is maintained when transcoding to H.264 format video data. When used in recording equipment like hard disk recorders etc., for the same hard disk storage capacity, the recording time can be lengthened by more than 2.5 times. The transcoded data size is reduced in the H.264 format so it also allows transmission of full HD video over narrow bandwidth networks in the home etc. H.264 HD Transcoder Stream in MPEG-2/H.264 HD/SD 3DES Dec TS Demux MPEG-2 HD Decoder / H.264 HD Codec TS Mux 3DES Enc Stream out H.264 HD/SD Internal Bus Audio Enc/Dec & Audio Time-stamp Video in Audio in Video/ Audio Input Memory Controller Host I/F Down Scaler HD>SD Video/ Audio Output Video out Audio out DDR2 Host I/F 512Mbitx2 Copyright 2007 FUJITSU LIMITED Disclaimer: The contents of this document are subject to change without notice.

MB86H52 MPEG-2 HL to H.264 HD Transcoder Features Transcoding MPEG-2 format HD video data to the H.264 format H.264 delivers the same quality as MPEG-2 at a half the data size. Proprietary technologies for compression and high quality video This LSI utilizes a proprietary algorithm developed by Fujitsu Laboratories that automatically applies less compression to areas in the image where compression artifacts are most noticeable to human vision, such as human faces or slow-moving objects, and greater compression to other areas. Thus high image quality for the critical zones is maximized. Due to that, the same video quality is maintained when transcoding from MPEG-2 to H.264. Includes Full HD H.264 CODEC The LSI includes a full HD H.264 CODEC for video encoding and decoding, so uncompressed video data can be compressed to the H.264 format. Also, this product can decompress video data from compressed or transcoded H.264.
