Matsushita Electric Industrial Co. Ltd. will release six types of recorders that have a 45nm-process LSI for the first time as consumer products. The release date is set for Nov. 1, 2007.

Each of the three Blu-ray Disc recorders and three DVD recorders can recompress digital broadcast signals into MPEG-4 AVC/H.264 High Profile format in real time.

By using an H.264 encoder mounted on a "UniPhier LSI," which was developed in 45nm process for digital audio-video equipments, the recorders compress video data of up to 1920 × 1080i size by about 75% without changing the number of pixels.

When recording on a one-sided two-layer Blu-ray disk (50GB), the new products can record 18 hours of digital broadcasting with the coding rate of 5.7Mbps.

The recompressed H.264 videos can be recorded on a Blu-ray disc, HDD and DVD. When a video is recorded on a DVD, "AVCREC," a new format developed by the Blu-ray Disc Association, is used.

In the AVCREC format, videos are recorded on CPRM-compatible DVDs in the BDAV format (comparable to DVD-VR for DVD). As a copyright protection format, AACS is adopted. AVCHD videos recorded by camcorders on SD memory cards can be copied to DVDs in the AVCREC format.

The Blu-ray Disc recorders to be released are "DMR-BW900" with a 1TB HDD, "DMR-BW800" with a 500GB HDD and "DMR-BW700" with a 250GB HDD. The maximum recording speed on a BD-R is 4x. Their expected shop prices are about 300,000 yen (USD 2,593), 230,000 yen and 180,000 yen, respectively.

The DVD recorders are "DMR-XW300" with a 500GB HDD, "DMR-XW100" with a 250GB HDD and "DMR-XW200V," which is equipped with a VHS recorder in addition to a 250GB HDD. The expected shop prices are about 130,000 yen, 100,000 yen and 130,000 yen, respectively.

The surface area of the substrate and the number of parts were reduced by 27% and 36%, respectively, by adopting a 45nm-process UniPhier.
