Snell & Wilcox’s MEMPHIS broadcast mastering encoder has been integrated with the Omneon SPECTRUM video server.
The integration provides high-quality MPEG-2 encoding along with control over media assets during ingest. The SD- and HD-compatible solution has undergone extensive testing to ensure robust plug-and-play performance.
Based on two technologies from Snell & Wilcox -- Ph.C phase correlation motion estimation and Prefix compression pre-processing -- the MEMPHIS encoder accepts both SD and HD 1080i and 720p formats as well as uncompressed PCM, MP1L2, Dolby E, and AC-3 audio. It can encode at any MPEG-2 profile including 4:2:0 and 4:2:2, CBR/VBR, and I-Frame/Long GOP up to 175Mb/s. Using the SMPTE 302M standard for audio encoding, both compressed and non-compressed audio streams can be embedded by MEMPHIS into the MPEG-2 output and then captured, stored, and automatically routed at playout by the Omneon SPECTRUM. Additional MEMPHIS features include support for EIA-608 and EIA-708 closed caption extraction as per SMPTE 334M and for the SMPTE 328M GOP timecode standard.
