For the first time, the cable Industry will take on an organized critical evaluation of the subjective effects of typical impairments to a television picture generated in a CATV system. In the past, this information was gathered from independent sources without verification or firm documentation. This upcoming study is sponsored by cable Labs under the direction of Tom Elliot, Vice President of Science and Technology. It will be conducted at the Jerrold Communications Applied Media Laboratory in Hatboro, PA. Bronwen Lindsay Jones, an Audio-Video expert in the field of psychophysical testing, has been contracted by cable Labs to establish this criterion for the subjective measurements and to record all data. The detailed results of this study will be published by cable Labs.
