Delivering HD spot - audio metadata and ATSC flag?
by Deadhead on May 19, 2006 at 6:47:37 pm
I am attempting to deliver a spot on HD (D5), and checking CBS's specs, it seems they require audio metadata and a brodcast flag or ATSC descriptor.
The question is how can I get that encoded so it can be output from my Kona 3 to a D5 deck.
Anyone have experience with this?
Here is the info from CBS's specs.
10. Metadata - The audio metadata should include the complete set of Professional Metadata (generated by a Dolby DP-570 multi-channel audio tool or equivalent equipment).
metadata shall be inserted into VANC space on line 9, luminance channel, in accordance with SMPTE 334M. This signal can be inserted into the SMPTE 292M serial digital signal with a Norpak TES-7 Encoder or equivalent equipment. A full frame's worth of metadata shall correspond to each video frame (see Table 1 for metadata settings). The SMPTE 334M Data ID (DID) number shall be set to 50h (hex), the Secondary ID (SID) number shall be set to 101h (hex).
The Broadcast Flag or ATSC content redistribution control descriptor shall be encoded on line 9 using the same syntax as used in SMPTE 334 and RP-207. The Data ID (DID) number shall be set to 162h (hex), the Secondary ID (SID) number shall be set to 101h (hex). The payload shall be one byte: AAh. If other metadata
to be supplied such as the ATSC OCAP interactive services, they shall also be encoded on line 9 of the luminance channel in accordance with SMPTE 334M.

What a great question. I hope someone can point you to some answers. Farming this out to a service house is likely the best / most immediate solution- unless you have time and are willing to invest in equipment and education. Below are a few informational links for your reading pleasure. I wish I could offer more help:
