The OnRamp QAM 16 Tuners/IP™ is a professional QAM to IP Gateway that inputs a mixture of streams from up to 16 cable channels and outputs them to an IP network. Resulting streams can be viewed with standard transport stream compatible servers or devices. The OnRamp QAM 16 Tuners/IP receives transport streams, demultiplexes the requested channels and forwards these channels using UDP or RTP via IP networks as either IP multicast or IP unicast streams. The OnRamp QAM 16 Tuners/IP can simultaneously receive transport streams from one to sixteen digital or analog clear QAM inputs. The system supports MPEG-2 input and output or H.264 input and output. Forwarding of PIDs via IP is transparent and does not alter the content of each individual stream. Depending on the configuration, it forwards selected programs via IP datacasting; PAT, PMT, video PID, audio PID(s) and PCR information are transmitted. The OnRamp QAM 16 Tuners/IP selects all required PIDs for a broadcast channel and sends them to an individual IP address.
