My first appointment of the day was with Tamihiko Ogawa and Hisashi Kasahara from NTT Electronics (SU10220). The company's big introduction this year are the AVC/H.264 HDTV/SDTV HVE9100 encoder and HVD9100 decoder. One of key features the men emphasized was that they feature 4:2:2 chroma for high-quality professional broadcast. The units are compact, lightweight and supports a wide range of applications, including MPEG-2.
In their booth you can see a series of displays showing the encoders and decoders. The first screen shows the original video footage. The second shows the video at 45Mb/s, 4:2:2 and 1920 x 1080. The third is at 18Mb/s, 4:2:2 and 1920 x 1080. And the fourth is at 8Mb/s, 4:2:0 and 1440 x 1080.
The HVT9100, an MPEG-2 to AVC/H.264 HDTV/SDTV real-time transcoder is another relatively new addition to the NTT lineup. It transcodes, while maintaining picture quality with minimal dealy in real time.
Update: NTT's HVE9100/HVD9100 H.264 encoders won a Pick Hit award!
