11. WRAPPERS: FROM MPEG-TS TO…
 AAF: Advanced Authoring Format by AMWA
(Advanced Media Workflow Association)
SMPTE 360 General Exchange Format (GXF)
MJ Drouin© - May 19th, 2010 - VSF

 SMPTE 377M Television . Material Exchange Format
(MXF) File Format Specification
 ASF: Advance System Format from Microsoft
 BXF: Broadcast Exchange Format for Metadata:
SMPTE 2021
 3GP for Mobile transmission: 3GPP (3rd Generation
Partnership Project) for GSM, 3GPP2 for CDMA,
etc…
 SMPTE 268M ANSI/SMPTE 268M-1994 SMPTE 11
STANDARD for File Format for Digital Moving-
Picture Exchange (DPX), Version 2.0

12. AMWA
 AAF wrapper for post production and video
editing workflows
MJ Drouin© - May 19th, 2010 - VSF
 MS06 Integration of MXF with BXF
 Mapping and addition of MXF metadata to BXF
(SMPTE S2021-2008). Provides compatibility
between BXF messages and MXF files.

14. QA OF FILES OR VIDEO CONTENT?
 Tests at ingest
 Exponential complexity with multiple providers
Internal set-ups stability
MJ Drouin© - May 19th, 2010 - VSF

 Sample test and use automatic metadata to your
advantage
 Test before the ‘ready for broadcast’

WHERE DO WE
START?

19. VIDEO OVER IP
 SMPTE 2022
 RTP, 1 to 7 MPEG-TS per packet
 Transmission (2022-2)
MJ Drouin© - May 19th, 2010 - VSF
 FEC (2022-1)
 IETF RTP
 Multicast UDP
 IETF FTP
19
 TCP

20. SO… WHAT’S NEW?
Ready to stretch a little bit?

21. UDP-BASED DATA TRANSFER (UDT)
 Created in 2001
 Current version #4 released in 2007
 IETF Candidate draft-gg-udt-03 (April 12th 2010)
MJ Drouin© - May 19th, 2010 - VSF
 Very high speed network (above DS3) – WAN
 File transfer of very large files (above 1TB) over long distances
 Unicast, duplex, connection-based
 Client-server or Rendezvous (P2P)
 Muxing
 Periodic ACK, relative to time and not traffic
 Congestion control (configurable, default = AIMD)
 Reliability mechanisms
 @ 155mbps, 50msec, 2x better than TCP
21
 @ 1Gbps, 25msec delay, 4x better than TCP


 Admission control – scheduling
 Precise synchronization
 Low delay
 2 msec through 7 ethernet bridges
 less than 1µsec between devices

24. AUDIO VIDEO BRIDGING (AVB)
The IEEE 802.1 Audio/Video Bridging
(AVB) draft standards:
 IEEE 802.1 AS
MJ Drouin© - May 19th, 2010 - VSF
 Timing and Synchronization for Time-
Sensitive Applications in Bridged Local
Area Networks (LANs); a precision time
synchronization protocol.
 IEEE 802.1 Qat
 Stream Reservation Protocol (SRP); an
end-to-end bandwidth reservation protocol
within a bridged LAN.
 IEEE 802.1 Qav – Accepted Dec 09
 Forwarding and Queuing for Time-
Sensitive Streams; A/V traffic scheduling
enhancements for a mainstream Ethernet
and other network switches.)
