And, for exhibitors, the good news is that the convention center really is finished. "We kept saying it was fmished, and it kept getting more and more fin- ished," said Stow. Inauguration of the new center is to take place 20 April. "We know we have some weakness, but we also know where our trumps are—particularly the politically neu- tral setting of Montreux where the pros and cons of technology can be exposed," said Feria. As for a "competing" annual IBC. Ferla said he was "nicely informed" by IBC Chairman John Wilson that "at this stage, the IBC has no inten- tion of doing an annual show."

The sessions will begin Thursday, 10 June and run through Tuesday. 15 June. The Technical Exhibition will be open from 10 am. to 6 p.m. from Friday, 11 June through Tuesday, 15 June.

Our synchronizer of choice has been the DPS-265 "Universal" synchronizer from Digital Processing Systems. Over the past two years we have purchased six of them, and they have performed flawlessly. One thing we have discovered is that you can never have enough frame syncs. Many sports arenas and stadiums are at Tv REPEATER least partially pre-wired for video, and Tv MODULATOR sometimes we need to get a camera shot, such as the scoreboard clock, from a location that is only served by a single ...... f ...... , ...... # # _ ••• coax cable. This makes it impossible to use triax or to run a genlock feed. Often, we also use wireless RF cameras or take feeds from microwave and satellite receivers. The frame synchronizer makes it a snap to handle any of these situations. And even though we have a traditional still store system in each of our trucks, we sometimes need to temporarily capture and display an additional still frame or two. When freezing moving video, the DPS lets us choose from any of five successive fields. For still images, such as character generator text, we use the four-field freeze mode for maximum transparency. The DPS synchronizers are extremely transparent, displaying no evidence of ringing or other picture distortions, but they are also quite rugged. Iii k11 AMPLIFIER We own nine 2 GHz microwave sys- 100 W tems, which we frequently rent. If one of AMV our customers needs a synchronizer, we just stick a DPS in the box with the TX microwave gear and ship it out.

I could not under- 200 W stand how a video synchronizer fitting on AMV a single PC card could be any good. However, I decided to take a closer look last fall when our uplink truck was hired to provide the primary Ku pool feed for the presidential debate from East Lans- ing, Michigan, and all of our DPS-265s were already committed.

Surprisingly, the new DPS MicroSYNC performance is on par with the DPS-265.
