—From the Video Services
Forum: VSF announced today the
publication of Technical Recommendation TR-03 “Transport of Uncompressed
Media over IP,” produced by the VSF Studio Video over IP Activity Group.
VSF SVIP Activity Group was tasked with developing a standard for video-over-IP
encapsulation with a specific concentration on live production. The group
requirements within the broadcast plant including video, audio, ancillary data,
timing, sequencing, identities, and latency. It then researched current and
and developed a gap analysis between the requirements and existing solutions.
TR is based on the Real Time Protocol (RTP) architecture developed by the IETF.
RFC 4175 to carry uncompressed video, AES67 for uncompressed audio, IETF
for ancillary data, and IEEE 1588 Precision Time Protocol for timing and
of the SVIP Activity Group, Michael Bany, senior engineer at DVBLink, Inc.,
said, “We are
proud that over 60 representatives from 30 companies in the broadcast industry
meetings that lead to TR-03. I feel that this TR represents a true consensus of
transport of uncompressed media over IP for production purposes.”
expect the use of live video-over-IP to enhance the flexibility and agility of
plant,” said Thomas Edwards, vice president of Engineering & Development at
and Operations, who participated in the SVIP Activity Group, “and we
TR-03 plays a significant role in making that vision a reality.”
draft TR is “TR-03 - Transport of Uncompressed Elementary Stream Media over IP
” (Published as a draft.)

SDI vs. IP: Packet to Packet
If one looks at the delay through an IP switch, it is due to the necessity to
buffer the packets as they arrive, are processed and then sent out. Depending
on the switch design, the traffic load, and the packet size, the performance
required in terms of packet loss dictates the buffer sizes.

If major industries, including manufacturing, transportation,
telecommunications, commerce and banking, have adopted IP, why not real-time
