Streaming methods
The IN SMD 100 input card supports the following streaming methods provided by the
Extron SME 100, Extron SMP 351, and 3rd party encoders:
•
UDP-TS
(Push) — Single program MPEG-2 Transport stream (SPTS), multicast only.
•
RTP
(Push) — Native (elementary video streams), multicast only. Single program
MPEG-2 Transport stream (SPTS) (RTP-TS), multicast only.
•
RTP/RTSP unicast or multicast
(Pull) — RTP and RTSP interleaved over a UDP
connection.
•
Unicast RTP over RTSP (RTP and RTSP interleaved over TCP)
(Pull) — Used for
on-demand video in which RTP is interleaved with RTSP over a TCP connection to
navigate fire walls that block UDP.
•
Unicast RTP over RTSP over HTTP (RTP and RTSP interleaved over TCP on
port 80)
(Pull) — Used where RTP is interleaved with RTSP over HTTP, to navigate
fire walls that allow HTTP (ports 80 or 8080 are open).
Streaming container format
The IN SMD 100 card supports the MPEG2 Transport stream (including .ts, .m2ts, and
.m2t file extensions) container format.
File formats
•
MPEG2 TS MPEG-2 part 1 (or ISO/IEC 13818-1 or ITU-T Rec. H.222.0)
•
MP4 (including mp4 and m4v file extensions, not case sensitive)
Video codecs
•
MPEG4 part 2 SP (<10 Mbps)
•
MPEG4 part 2 ASP (<10 Mbps)
•
MPEG4 part 10 (AVC) H.264 BP, MP, HiP up to level 4.2 (<62.5 Mbps, 1 sec)
•
JPEG over RTP
Protocols
The IN SMD 100 supports the following network protocols, depending on the source and
network properties.
Application layer protocols:
•
HTTP and HTTPS
(Hypertext Transfer Protocol and Hypertext Transfer Protocol
Secure – RFC 2068) — Used for serving internal web pages to clients and for server
control.
•
RTP
(Real-time Transport Protocol – RFC 3550) — Adds the ability to obey
embedded timestamps to maintain synchronization among multiple streams.
•
RTP/AVP
(Real-time Protocol/Audio Video Profile – RFC 2250, 2435, 6184) —
Describes the payload type being transmitted via RTP.
•
RTCP
(RTP Control Protocol – RFC 3550) — Required for RTP and useful or
necessary for determining network status, performance, and troubleshooting.
•
RTSP
(Real-time Streaming Protocol – RFC 2326) — Over TCP and UDP as defined
in
RFC 2326, April, 1988
