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 Audio-Visual Council (DAVIC), and the Society of Motion Picture and 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. |
