Here is some background for Dec. talk. Go DIVI!
Dealing with System Information
Matthew Goldman, DiviCom
Matthew Goldman is Director of Engineering, DiviCom, Inc. Mr. Goldman
joined DiviCom in 1996 as a systems architect. In his current role as director
of engineering for advanced systems, Mr. Goldman is responsible for
systems engineering, strategic planning and product definition, as well as
driving support for open industry standards.
Prior to joining DiviCom, Mr. Goldman was a consulting engineer at Digital
Equipment Corporation, where as one of the principal architects for the
video server product line, he defined end-to-end systems models, network
interfaces, control signaling, and MPEG video storage and delivery
mechanisms. Over his more than 10 years at Digital, he was involved in
several projects where he designed hardware modules and integrated
circuits.
Mr. Goldman holds both bachelor and master of science degrees in
electrical engineering from Worcester Polytechnic Institute. He holds six
patents for real-time video transport and digital video stream control. Mr.
Goldman has been influential in several digital video related standards setting
organizations, including the International Standards Organization Moving
Picture Experts Group (MPEG), the Advanced Television Systems
Committee (ATSC), the ATM Forum Technical Committee, the Digital

Television Engineers (SMPTE).
Abstract
System information, also referred to as program or service information, is the
collection of ancillary information which describes the contents (video, audio
and data) of the digital television bit stream. The information is related to
"tuning" (bit stream identification and selection), program guide support,
content advisory, closed captions, conditional access, and data stream
relationships. It is typically formatted as a set of tables containing
descriptors. This paper will give an overview of the MPEG transport stream
program specific information, the ATSC's program and system information
protocol standard (A/65), and related standards. How system information is
carried into and out of the studio will be described, and unresolved station
issues will be discussed.
If high level set tops take over DIVI has the capital to deliver the goods. |
