SIVAC 3000 MVE Encoder (SDTV MPEG-2) SIVAC 3000 MVE is SAPEC’s MPEG-2 SDTV (ISO/IEC 13181) family of video and audio encoders with transmission over DVB-ASI, IP (RTP/UDP with COP3 FEC SMPTE 2022) and PDH (E3/DS3), that can work even simultaneously. SIVAC 3000 MVE supports analog (PAL/NTSC) and digital (SDI) video inputs and it is capable of encoding up to 8 channels (4 stereo pairs) of embedded audio, AES/EBU or analog audio. Analog inputs can be equalized and adjusted. SIVAC 3000 MVE allows video and audio to be encoded from different inputs, what gives great flexibility and avoids the need for external converters or embedders. SIVAC 3000 MVE processes the vertical blanking interval inserting teletext, test signals (VITS) and aspect ratio (AFD, WSS). Teletext source may be different from video input, providing maximum flexibility and no need for external embedders. SIVAC 3000 MVE has been designed with an internal multiplexer that can create one PMT with video, audio and VBI data, and up to other three PMT’s for audio channels (radio broadcasting). SIVAC 3000 MVE supports MP@ML (MVE 30x0) as well as 422P@ML (MVE 32x0) profiles, enabling the user to select GOP size and structure, encoding resolutions (NTSC: 352x480 to 720x480; PAL: 352x576 to 720x480) and bitrates for audio (64 kbps to 384 kbps per stereo channel) and video (MP@ML: 1 to 15 Mbps; 422P@ML: 2 to 50 Mbps) in order to meet different needs. SIVAC 3000 MVE uses the latest breakthroughs in MPEG-2 compression technology to deliver the best image quality with minimum encoding-decoding delay (less than 180 ms over ASI and PDH in combination with SIVAC 3000 MVD) and due to the patented technology FastIPSync®, it is able to reduce jitter in IP networks, as it uses an exclusive algorithm that adapts dynamically itself to IP network conditions. It is possible, nevertheless, to add an extra-delay in order to be interoperable with mid-range and low end decoders (usually consumer set-up boxes). SIVAC 3000 MVE supports configuration via web browser and front panel, and also provides an SNMP agent for external monitoring. The equipment can also be managed centrally and simultaneously with SIVAC-NMS management system. SIVAC 3000 MVE offers a build-in 1+1 autonomous redundancy system that provides a reliable audio and video signal transport. SIVAC 3000 MVE power supply is AC + DC, and it has a DC output, what allows to feed another unit with only one power supply. SIVAC 3000 MVE has low power consumption (less than 20 W), making electrical installations easier. |
