Here it is. DIVI and many of its partners were there. NTELSAT / ISOG Tests Prove DVB Plug and Play Interoperability INTELSAT announced the results of its third round of extensive digital video interoperability testing. This latest round of tests was designed to achieve "plug and play" operation for both NTSC and PAL standards, and at several different parameter sets. It was certainly a watershed for the DVB Project as no less than nine of the systems tested were manufactured by DVB members. The tests, conducted 24 February to 4 March at INTELSAT's Technical Labs in Washington, D.C., focused on single-channel video compression equipment used for SNG, occasional use and low data rate contribution applications, and demonstrated how well different manufacturers' digital video equipment worked together. The test program was undertaken as a response to requests to resolve equipment incompatibility issues that INTELSAT had received from the Inter-Union Satellite Operations Group (ISOG -- which represents large broadcasters and INTELSAT Signatories) as well as from other companies and groups around the world. For this third round of testing, the participating equipment manufacturers included: California Microwave/STS; Divicom; DMV/NDS; Magnitude Compression Systems, Inc./General Instruments; Scientific-Atlanta, Inc.; Tadiran Scopus DVC; Tandberg Television AS; Thomson Broadcast Systems; Tiernan Communications, Inc.; and Wegener Communications . Test equipment for the program was supplied by Adherent Systems (formerly Symbionics) , Hewlett-Packard and Tektronix. All of the manufacturers' equipment was DVB-compliant.. The INTELSAT Test Report documents the results of how well each encoder interoperated with each of the decoders (IRDs) simultaneously, for each of the parameter sets tested. For each configuration, the presence of audio, video, MPEG-PSI and subjective lip sync were noted. Objective lip sync measurements were conducted in several of the test configurations as well. Vince Walisko, Director of Business Development for INTELSAT's Video Services division, noted, "The testing has been extremely successful in moving the industry toward a 'plug and play' environment. The Test Report which has resulted from these efforts should prove a most valuable guide to the broadcast community. Customers can use the Report to review and select which equipment group will work best for each specific application they require." In testing "plug and play," the only equipment adjustments allowed were those which are accessible to the typical user (i.e., front panel control or PC set-ups). While successful "plug and play" varied with the different parameter sets, each manufacturer's equipment was able to interoperate with the equipment of several other manufacturers, as documented in the Test Report. "This has been a remarkable and unique achievement of cooperation in the industry," said Dick Tauber, Vice President of Satellites & Circuits at CNN, and ISOG Chairman. Gary Smith, INTELSAT Vice President of Sales and Marketing, commenting on the interoperability testing, noted, "We think these tests will give our customers the additional comfort they need to move ahead with using digital equipment and digital transmission services at an accelerated pace. This, in turn, helps lead the whole industry forward." Copies of the Test Report are available from INTELSAT's Corporate Communications Department.
