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 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.

Re 3COM... Is this what they bring to the set top? cabledatacomnews.com 3Com Starts Shipping Two-Way DOCSIS Solution TCI Planning Buy-Only Launches with 3Com to Answer Key Cable Modem Retail Questions 3Com Corp. announced it has started shipping its two-way DOCSIS cable modem system to Tele-Communications Inc. (TCI) and other operators. TCI has started a field test of the products, which include the 3Com Total Control cable modem termination system (CMTS) and U.S. Robotics Cable Modem CMX, in Spokane, Wash. 3Com is working hard to push its DOCSIS cable modems into retail stores and the company has found a friend in TCI, which cannot wait to eliminate cable modem capital expenditures. However, due to high initial cable modem costs, limited service availability and delays in DOCSIS certification, both parties agree it will take time and effort to make retail a reality for MSOs. 3Com built its CMTS using its flagship Total Control remote access concentrator platform, which is widely used by dial-up ISPs and enterprise customers. 3Com's two-way external U.S. Robotics Cable Modem CMX carries a suggested retail price of $319. 3Com is also offering the U.S Robotics Cable Modem CMI, an internal PCI card with a suggested retail price below $300. DOCSIS certification will start in Dec. and it looks like 3com is ready. cabledatacomnews.com DOCSIS vs DVB in Europe.... In this territory DIVI and 3 COM seem to be in opposite camps.. but in the US I don't know. The Market will Decide DVB vs. DOCSIS Debate Dueling cable modem standards coalitions took the stage at the European Cable Communications show in October to promote their positions. Nine cable vendors joined the DVB/DAVIC Interoperability Consortium to advance digital cable modems and set-tops based on the technology. The participants include: Alcatel, COCOM, DiviCom, Hughes Network Systems, Nokia, Sagem, Simac, Thomson Broadcast Systems and Thomson Multimedia. This fall, EuroCableLabs issued a RFP for DVB-based cable modem equipment. Not to be outdone, a dozen other vendors formed the European Cable Modem Coalition to advocate the use of products that meet the ITU-TJ.112 cable modem standard, which combines DOCSIS technology with a DVB downstream physical layer. These DOCSIS-driven vendors include 3Com, Broadcom, Cisco Systems, Dassault IT, Deltakabel, Elsa, FUBA-General Instrument, Motorola, Pace, Samsung, Teldat, and Tonna. Trying to get to the bottom of this debate? Forget the rhetoric and follow the purchase orders. The early winner in the DOCSIS vs. DVB cable modem spat will be apparent by next spring as European cable operators start placing high-volume cable modem orders. We're placing our bets on the DOCSIS crowd for initial customer wins, but expect there to be meaningful technical convergence between the camps over the next three years to prevent significant market fragmentation.
