[irig106-announce] Brief summary of Chapter 10 changes

[<Bob...@gt...>]

I just got back from the spring RCC meeting.  There was a big push to
finish up and publish the latest IRIG 106 Chapter 9 and Chapter 10
guides.  There *was* going to be a -06 (i.e. 2006) release but now it's
been decided that the release will be called IRIG106-07.  Expect it out
by summer.

There haven't been any major shifts in the spec.  Some new data types
have been added, some wording has been cleaned up, and a couple of new
sections have been added to the end.  Here are the highlights (as I can
remember them)...
=20
New data types
=20
MIL-STD-1553 Format 2 (0x1A) - This format is used with the rather
esoteric F-16 16PP194 bus.  Trust me, that's probably all you care to
know.
=20
Video Data Format 2 (0x42) - ISO 14496 MPEG-4 Part 10 AVC/H.264
=20
Image Data Format 1 (0x49) - Still imagery
=20
IEEE-1394 Format 1 (0x59) - IEEE-1394 physical layer
=20
Ethernet Data Format 0 (0x68) - Ahhh... Ethernet data. What else can I
say...
=20
New Sections
=20
10.3.11 Recorder Data Streaming - Ethernet is an optional interface but
if it's available there are prescribed ways of using it.  Data streaming
is a new defined feature for Ethernet.  Data streaming defines the UDP
packet structure for recorders to stream their live data out of the
recorder over UDP for external real time use.
=20
10.10 Ground Based Recorders - This is an attempt to define features and
operations for a ground based recorder that operates more or less like
an airborne recorder.  Defining this section has been a lot harder than
you would think.  It's still a work in progress.
=20
10.11 Data Interoperability - This section levies some requirements on
processes data files.  For example, if you trim a data file by time or
filter out channels, there is now a requirement to rewrite some TMATS
fields in the new data file to document this. There is also a lot of
stuff in here about file naming.
=20
Chapter 9
=20
There are now a lot of TMATS fields required for Chapter 10 recorders.
Chapter 9 now has annotations indicating required fields.
=20
Enjoy!
