Implements a Real Time Transport Protocol (RTP) hardware stack that encapsulates H.264/NAL streams to RTP packets that are compliant with RFC 3894 and RFC 6184.
The H2642RTP can be directly connected to the output of an H.264 encoder to output RTP packets, which can subsequently be forwarded for UDP/IP or TCP/IP encapsulation. The hardware stack produces complete RTP packets, without the need for any host-processor assistance. Along with CAST’s UDP/IP hardware stack, the H2642RTP core is ideal for offloading the demanding task of RTP/UDP/IP encapsulation from a host processor, and enables H.264 video streaming even in processor-less SoC designs.
The core is easy to integrate in systems with or without a host processor. H.264 stream and RTP packet data are input/output via dedicated streaming-capable interfaces, enabling direct connection to hardware video encoders and hardware stacks for UDP or TCP. Status and control registers are accessible by an AXI4-Lite interface.
The H2642RTP core is available in RTL source or as a targeted FPGA netlist. Platforms integrating the core along with an H.264 encoder, UDP/IP, and eMAC cores, are also available from CAST, and can enable rapid development of video over IP systems.
