The Technical Performance of Typical Home Color Television Receivers

Technical performance data for typical home television receivers is not generally available although knowledge of receiver characteristics is important to the broadcast engineer. The Canadian Broadcasting Corp. has undertaken to meet this need by measuring the performance of 11 color TV receivers of 11 different manufacturers. Measurements were made of the video, audio, RF, and acoustical performance. The study discovered very large spreads of performance within the sample of receivers for any given parameter. Broadcasters can draw on these test results to establish the performance profile of a “standard” TV receiver for use in setting their broadcast system standards. The level of performance of this “standard” receiver should be based on the performance of the better receivers. Major deteriorating parameters were: resolution limitations, ringing and edging effects, audio bandwidth limitations, audio channel periodic noise, scanning nonlinearity, and black level shift with average-picture-level changes.
