The MTS-E megafunction multiplexes and encapsulates audio, video and metadata streams in a single MPEG Transport Stream (TS), and optionally encapsulates the TS packets in Real-Time Transport Protocol (RTP) packets.Under its default configuration, the MTS-E multiplexing and encapsulation engine supports two input stream channels, e.g., one Audio and one Video. Configurations with more than two input stream channels can be made available upon request. The output transport stream can be forwarded for local storage or transmitted over an Internet Protocol (IP) or other network. Streaming over IP networks often imposes further encapsulation of the transport stream in RTP, UDP, and IP packets. The MTS-E megafunction can be programmed to perform RTP encapsulation, while the companion UDPIP megafunction from CAST supports UDP/IP encapsulation.


  • MPEG Transport Stream Multiplexing & Encapsulation
  • Flexible Encapsulation: Software programmable PES packet size and TS packet group size. Optional Program Info, and l Elementary Stream Info support
  • RTP Encapsulation: Software enabled/disabled encapsulation of the MPEG Transport stream in RTP packets
  • Compliant to ISO/IEC 13818-1. Supports Audio, Video & Metadata stream types
  • Two input stream channels (additional channels upon request)

Device Utilization and Performance

MTS-E reference designs have been evaluated in a variety of technologies. The megafunction configured with one input stream channel, no RTP, no TS packet grouping an no Program ES info support uses 678 ALMs and 65,536 RAM bits in an Arria® V device.
