Subscriber Response System; El Segundo Interim Test Report.
Callais, Richard T.
A new cable television system, called the Subscriber Response System (SRS), is being tested prior to a trial installation in El Segundo, California. The components include two bidirectional cables, a computer for processing subscribers' requests, and subscriber terminals to be located in homes or offices. The home terminal includes a three-digit keyboard or a full numeric keyboard with a strip printer. The first phase of testing has showed the full SRS system transmits data with high reliability in the presence of typical or even excessive thermal noise. Tests of the computer and software showed the system can deal with heavy service traffic with an average interrogation response time from 2.4 to 13.3 seconds for 50,000 subscribers. Initial consumer use of the system will be for meter-reading, shopping from the home, reservation services and emergency services. Other services to be tried may include pay TV, interactive education in the home, audience participation programs and off-track betting. (MG)
