Rich Chernock, Director of Technology at Triveni Digital is presenting a session on ATSC Bitstream Monitoring at the NAB2006 Broadcast Engineering Conference. The session is scheduled for Wednesday, April 26, 2006 from 10:00 AM – 10:30 AM in room S221 at the Las Vegas Convention Center. Chernock’s presentation is a subset within the overall “Managing Your Multicast” session taking place from 9:00 AM – 12:00 PM.
The “correctness” of an ATSC DTV broadcast is critical to ensure that all viewers will be able to watch the broadcast content. An Ad Hoc group within ATSC (TSG-1, Bitstream Verification) was created to describe the elements of the appropriate standards (A/53 and A/65) that must be verified in a transport stream for it to be considered a proper emission.
Chernock will summarize the findings of that activity, including enumerating the possible error conditions within an emission transport and establishing what’s important vs. what’s somewhat wrong (but may not have much impact). While all violations of the standards in an emission are incorrect, some might call for immediate response. Examples of the types of problems to be discussed include missing elements (which might result in inability to tune, missing programs or missing components of programs), table conflicts (which may confuse receivers and interrupt decoding) and timing problems (results ranging from inability to tune to slow tuning or updates of information).
Dr. Chernock is the Director of Technology at Triveni Digital. In that position, he is developing strategic directions for metadata management, content distribution and monitoring in emerging digital television systems and infrastructures. Previously, he was a Research Staff Member at IBM Research, investigating digital broadcast technologies. Dr. Chernock is active in a number of the ATSC standards committees, particularly in the area of metadata and data broadcast. He chairs a number of adhoc committees within ATSC whose work relates to metadata and transport issues. He is vice-chair of the Technology Group on Distribution (TSG). In another life, he used transmission electron microscopy to study materials characteristics for advanced ceramics packaging and semiconductor technology at IBM. His ScD was from MIT in the field of nuclear materials engineering.
