There have been many learned papers describing the detailed technical aspects of teletext transmission; most in language only understood by others with an intimate knowledge of the subject. This paper defines the requirements for the practical implementation of home teletext reception in the cable television environment.
Since data integrity is the measure of technical success, the items which effect data integrity are deliniated. Included are the satellite path, receive earth station, satellite receiver, cable modulators, AML link, and the cable plant itself. Results of various measurements and observations describing the effect of each subsystem have been made and the results will be described. Practical suggestions for achieving desired results in the most critical areas are presented.
