Sapec will present the low-delay 4:2:2 profile in its family of HD Altum encoders at CABSAT 2012

From February 28 to March 1 at booth S1-H22 at CABSAT 2012, Sapec will present its new family of HD Altum encoders, as well as an SD headend made with the SIVAC family.

Sapec, a company specialized in solutions for the transmission of video and audio signals, will present at the CABSAT 2012 fair from February 28 to March 1, 2012 at stand S1-H22 the Hi422P@L4 (HD 4:2:2) encoding profile in H.264 with low delay in its family of Altum high-definition encoders. Likewise, the latest improvements of SIVAC equipment will be shown.

The Altum family is Sapec's second generation of high definition (HD) multi-format (H.264/MPEG-2) encoders and decoders. Altum equipment is specifically designed for HD and to support 4:2:0 and 4:2:2 encoding profiles in both MPEG-2 and H.264, which makes it suitable for both contribution links and high definition content distribution.

The video and audio interfaces of the Altum family devices are completely digital: one HD-SDI/SDI port for video and 4 or 8 embedded SDI audio and 2 or 4 AES/EBU channels for audio.
Regarding transport interfaces, Altum equipment has one or two IP ports and, optionally, DVB-ASI (in the encoders two output ports and in the decoders one loop input and output port).

At the Sapec stand at the fair, a contribution made with an ALtum encoder/decoder pair configured in H.264 HD with 4:2:2 profile (Hi422P@L4) at 30 Mbps in low delay mode will be shown.

A simple headend will also be exhibited that will consist of a Sivac encoder (MPEG-2 SD equipment) that will encode signal with the MP@ML profile (SD 4:2:0) of MPEG-2 at 4 Mbps and a multiplexer. The resulting signal will be decoded by a Sivac decoder.

Sivac equipment, with a consolidated presence in the market, are MPEG-2 SD encoders and decoders designed and manufactured by Sapec for television signal contribution and distribution applications that come in three formats: SIVAC 1000 (1RU units with front configuration panel), SIVAC 2000 (2RU modular units with capacity for up to 4 encoder/decoder cards) and SIVAC 3000 (1RU units without front configuration panel).

The MTS-1000 and MTS-1400 multiplexers of the Sivac family are devices capable of combining up to 8 ASI Transport Stream inputs (MPTS or SPTS) and provide the necessary tools for the formation and manipulation of the output stream, including the manipulation of each PID independently. They support MPEG, DVD and ATSC standards. The MTS-1400 model also supports switching in the output configuration in case of error or failure at the input.
