SAN FRANCISCO LSI Corp. has unveiled what the company calls the first high-definition (HD), real-time encoder to support "full HD," 1080p60, the highest resolution format for HD content, the company said Wednesday (April 11).
The encoder, designated DX-1810, is the first member of LSI's Domino[X] Pro product family, an extension of the Domino[X] architecture for media processors that the company rolled out last October. The DX-1810 is a scalable platform that supports H.264, MPEG-2 and VC-1 compression formats, according to LSI (Milpitas, Calif.). The company said the device's high output quality makes it ideal for TV program content delivery as well as for Blu-ray Disc and HD DVD real-time authoring systems.
According to Bob Saffari, senior director of marketing for LSI's advanced video products, the DX-1810 platform achieves the performance required for high quality 1080p60 encoding at the lowest possible bit-rate. Using interconnected media processors with high-speed interfaces, the DX-1810 platform can be scaled to perform at 3,500 billion operations per second (BOPS) or 3.5 tera operations per second for audio-video processing and 12 BOPS for high-level image analysis, statistical multiplexing and system level operations. The scalability of the LSI solution allows additional media processors to be added for HD level pre-processing such as motion compensated temporal filtering to improve video quality or to create dual- or triple-pass HD encoders for bandwidth constrained multi-channel broadcast applications, according to the Saffari.
"Satellite TV, cable TV and IPTV service providers want high-quality encoding solutions that can be upgraded as compression algorithms improve and as new compression formats are introduced," said Michelle Abraham, senior analyst at market research firm In-Stat, in a statement released by LSI. "The scalability and programmability of solutions such as the LSI DX-1810 encoding platform give the performance, quality and flexibility required by this class of sophisticated customers."
The DX-1810 features a programmable architecture with common APIs, making it easy to upgrade the encoding quality and reduce the output bit-rate as improvements are made to the H.264, MPEG-2 and VC-1 encoding algorithms or to support new compression formats as they become available, Saffari said. The DX-1810 is backwards compatible with other LSI encoding solutions, he added.
LSI plans to demonstrate the DX-1810 along with other solutions at the National Association of Broadcasters (NAB) show next week in Las Vegas. The company is offering a podcast series on trends in the professional video and broadcast infrastructure market on its Web site.
