MPEG-2 HL to H.264 HD Transcoder LSI
Transcoder LSI (MB86H52)
Fujitsu's transcoder chip can compress full HD (1,920 dots x 1,080 lines) MPEG-2 video data to H.264 data. The chip, MB86H52, is a transcoder that can compress MPEG-2 video to less than half the data size.
This transcoder product compresses the video data size while maintaining high video quality so it can be used in recording equipment like hard disk recorders, where the recording time can be lengthened by more than 2.5 times. With the expected increase of home network appliances, this product allows transmission of full HD video over narrow bandwidths. Also there are many opportunities to embed this LSI in equipment where the video data size needs to be reduced.
Digital terrestrial broadcasts and digital satellite broadcasts are compressed into the MPEG-2 format and then broadcast. The MPEG-2 format provides high-resolution video. However, f you want to record the video as it is to storage media like a hard disk, the data size is very large, so the recording time is limited.
Focusing on such issues, Fujitsu developed this MB86H52 transcoder LSI that converts MPEG-2 format video data to the H.264
format, which has higher compression. 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 new transcoder LSI maintains the quality of the inputted MPEG-2 video data when transcoding to
H.264 format video data.
