This compendium of papers, prepared by staff of a Canadian public cable company, examines cablevision marketing in Canada, multiple replay community programming, the first QCTV film production, QCTV special programming, television coverage of the House of Commons, establishment of a data processing system, use of that system for customer service, and increasing performance capabilities of the expanding system. Results of a survey of 20 cable television companies in urban centers across Canada indicate the effectiveness of marketing practices in the cable television industry. Another survey of QCTV subscribers examines whether multiple replays of community programs result in drawing larger audiences, thereby cost-justifying programming expenditures. The production of and public reaction to QCTV's first film, a documentary, and to a special programming series for the deaf and hard-of-hearing are also presented, as well as the results of a subscriber poll which indicated favorable reactions to television transmission of House of Commons proceedings. The transition from a batch-processing method of subscriber account processing to an online system and the benefits of subscriber-oriented programs in an online computer system are examined. The final paper describes the introduction of hub-headends and conversion to FM transmission, which have resulted in lower maintenance costs, and increased system reliability. (CWM)
