Transcoding Technology

        An important feature developed for the IPTV products is the ability to transcode one media format to another. We have developed the ability to transcode compression formats from MPEG-2 to MPEG-4 and to transrate from MPEG-2 at a high bit rate to MPEG-2 at a lower bit rate. The source can be either a variable bit rate, or VBR, or constant bit rate, or CBR feed. Some of the technology is licensed from a technology vendor and integrated into our products. We have also developed the ability to pass-through specified elements of the audiovisual information without transcoding, such as closed captions and audio streams. In addition to transcoding at the compression layer, we have further enhanced our networking capabilities to perform translation of the network layer between DVB, IP/Ethernet and ATM according to the needs of the service provider. With regard to ATM we have developed the capability of transmitting audiovisual content over native ATM and over IP over ATM.

Transcoding technology

        An important feature developed for the IPTV products is the ability to transcode one media format to another. We have developed the ability to transcode compression formats from MPEG-2 to MPEG-4 (compliant with part 2 or part 10, the latter also referred to as AVC or H.264), from MPEG-2 to Windows Media compliant format and to transrate from MPEG-2 at a high bit rate to MPEG-2 at a lower bit rate. The source can be either a variable bit rate, or VBR, or constant bit rate, or CBR, compression format. Some of the technology is licensed from a technology vendor and integrated into our products. We have also developed the ability to pass-through specified elements of the audiovisual information without transcoding, such as closed captions and audio streams.
