Individual Video Menus to Check Into Hotel TV : Technology: A new transmission system promises guests freedom of choice and high-clarity images in a joint venture by two Texas companies.

Hotel guests will soon be able to click on the television and pick a film from a library of video titles, developers of a new transmission system said Wednesday.

The new high-tech operation, which promises to deliver high-clarity images, will be the product of a joint venture announced by two Texas-based companies: Spectradyne in Richardson and EDS in Dallas.

Spectradyne, a leading provider of in-room, pay-per-view television, already claims links to 700,000 rooms in 2,500 hotels in the United States, Canada and Mexico. EDS, a unit of General Motors Corp., is a leader in information technology.

The two companies said they will deliver the movies using Compressed Digital Video, a communications system that can also provide a video-conferencing link.

The CDV system is the creation of Compression Labs, based in San Jose.

Officials of Spectradyne, a subsidiary of SPI Holding Inc., said the $20-million system will be installed in two phases, with the first to be completed in about nine months.

Phase Two would permit hotel guests to select from a menu of 20 to 50 films and play their selections at will, a change from the current system in which guests must wait until a new movie cycle begins.

Spectradyne recently announced that it is testing a system with U.S. West at three San Francisco hotels that permits hotel visitors to use a special channel, City Key, which offers items such as a descriptive listing of 4,000 restaurants.

Al Jerome, president and chief executive of Spectradyne, and Harry Budow, marketing vice president, said the new system with EDS will also permit delivery of specialized radio programs similar to those offered by airlines.

The signals for the new system will be delivered to hotels by Ku-band antenna, microwave or fiber optics.

Spectradyne said that by using the system, hotels will make more money by offering major event telecasts such as championship boxing and rock concerts.

Jerome said the radio offerings will be used to deliver national advertising for which the hotels will receive a share of the revenue.
