 Snell & Wilcox’s MEMPHIS encoder can embed both compressed and uncompressed audio streams into the MPEG-2 output. |
Turner Entertainment Networks has standardized on the Snell & Wilcox MEMPHIS as the mastering encoder for all content played out on its HD networks. Turner has purchased 22 MEMPHIS systems, which are being used in its Atlanta facility to provide MPEG-2 encoding of HD content prior to playout and archiving.
Turner uses MEMPHIS to ingest HD content in a format compatible with its Pinnacle MediaStream servers and online storage infrastructure. By using the MEMPHIS variable bit rate option, Turner is able to maintain robust and clean video pictures while optimizing the bit rate for its distribution and transmission requirements. The MEMPHIS systems installed at Turner also process CIE-708 closed captions and carry Dolby-E audio.
MEMPHIS accepts inputs in both SD and HD (1080/720) formats, 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, MEMPHIS can embed both compressed and uncompressed audio streams into the MPEG-2 output. These streams then can be captured, stored and automatically routed at playout by the playout server.
Additional features include support for EIA-608 and EIA-708 closed caption extraction as per SMPTE 334M and for the SMPTE 328M GOP timecode standard.
