MPEG encoding is a critical step in Digital Video Broadcasting. Even with standard definition signals the video must be encoded in order for it to be distributed through digital channels. Usually this is through MPEG-2, as most current infrastructure and set top boxes work with this standard. Most cable headends deal with hundreds of channels, and it is easy for racks to quickly overflow with equipment. Our CL-4SD-ENC system is designed to address this issue. Our unit reduces the required rack space for encoding equipment by incorporating 4 standard definition encoders into one unit. The CL-4SD-ENC then multiplexes the output ASI signals into a single transport stream. This unit is actually five pieces of equipment in one, encompassing 4 SD MPEG-2 encoders and an ASI multiplexer; all in a single 1U rackmount enclosure. In addition to the multiplexed ASI output our unit also features IP transport stream output. The encoded channels can easily be transported over IP networks and even over the Internet to remote locations. With the future of DVB moving to IP based transport, the CL-4SD-ENC is a solid investment in the future of digital video broadcast.
