The QVidium® SDI MPEG2+4 IP Codec provides a compact and reliable solution for transporting live standard-definition SDI video with embedded audio, NTSC and PAL streams across an IP network. QVidium’s SDI MPEG2+4 IP Codec implements QVidium’s patent-pending ARQ error correction as well as the latest version of the Pro-MPEG Forum’s standard, Code of Practice (COP) 3 release 2 with Forward Error Correction (FEC) for reliable and interoperable video transport.

The QVidium® SDI MPEG2+4 IP Codec can be quickly configured through its intuitive web interface as either an encoder or decoder, or both. As an encoder digitizes SDI digital or composite analog video signals, along with stereo audio, compresses them using MPEG-2 (MP@ML) or MPEG-4 (SP@L1, L2 & L3, Full D1 & interlacing) 4:2:0 and MPEG-1 Layer-II audio compressions, multiplexes the video and audio streams and produces a DVB-compliant MPEG-2 Transport Stream. It can accommodate both PAL and NTSC video formats. As a decoder, it accepts any ProMPEG, RTP/IP, or UDP/IP encapsulated MPEG-2 Transport Stream, and decodes MPEG2 or MPEG4-SP video through its digital SDI and composite video outputs.

It encapsulates the video transport stream into IP packets using the UDP or Real Time Protocol (RTP) for complete interoperability with Set-Top Boxes (STB) and other UDP and RTP compliant gateways. The encoder is fully compliant with the Pro-MPEG COP #3 Standard for complete interoperability with QVidium’s and third-party networked video devices that also comply with the Pro-MPEG standard.

The QVidium® SDI MPEG2+4 IP Codec includes two forms of error correction: ProMPEG FEC and QVidium’s patent-pending ARQ. Full video transport quality can be maintained even in the face of packet loss, packet duplication and packet re-ordering from the IP network when used in conjunction with a Pro-MPEG FEC or QVidium ARQ compatible receiver.

The QVidium® SDI MPEG2+4 IP Codec is simple to set up and maintain. An intuitive web interface control allows configuration and monitoring from any location on the network using a standard web browser from any networked computer. The system also supports Telnet access.

Application Example:

• Advanced error correction, selectable between Pro-MPEG COP 3 Release 2 FEC and QVidium’s patented ARQ, maintains video transport quality despite packet loss, reordering, and duplication.
• QVidium’s advanced packet pacing & configurable jitter buffer eliminates and handles large packet bursts.
• Compliance with DVB standards insures interoperability. Interoperable with Set-Top Boxes (STB).
• MPEG Encoding up to 9 Mbps and very low cost per channel provides a very cost-effective solution.
• Send & receive audio & video simultaneously. Two Codecs provide a complete video/IP end-to-end solution.
• Silent fan-less design with built-in power supply and removable rack-mount bracket.
• Includes SDI, composite video, and analog audio inputs and outputs. Handles SDI embedded AES audio.
• Composite and SDI video signal front-panel indicator lights for inputs and outputs.
• Transport of serial RS-232 data over IP for remote camera control.
