H.264 Video Over IP – HD Encoder Subsystem

This Video Over IP Subsystem integrates H.264 compression, Transport Stream and RTP/UDP/IP encapsulation to enable the rapid development of complete video streaming products. Hardware reference designs and customization services complete the solution. 

The subsystem can be configured to use one of the H.264 Low Power or Ultra-Fast encoder cores and the MTS-E, RTP and UDPIP, hardware stacks available from CAST. Flexible interfaces allow easy integration of video, memory, and network controllers, and AXI4-Lite slave interfaces allow a host processor to access all control and status registers. An optional custom logic module allows standalone, processor-free operation and provides access to control and status registers via UDP packets. Video and stream data are transferred among the subsystem’s modules using AXI-Stream, making removing or adding modules straightforward.   

The produced stream can be decoded using H.264-compatible software viewers (e.g. VLC), or CAST’s Low-Latency H.264 Decoder subsystem.
