New devices and technologies in the home are creating new challenges for converter manufacturers. For example, one of the most popular applications of VCR's is time shifting of programs for later viewing. But subscribers wishing to use their VCRs' programmable features are finding their cable converter an obstacle. Another example: With the introduction of stereo television, NCTA-commissioned research has identified many technical problems associated with carriage of the broadcast stereo method on cable systems. Yet cable needs a practical stereo delivery method to keep its product competitive with broadcasters. An addressable converter system design approach is discussed by which these two consumer phenomena - the VCR and stereo TV - may be eliminated as problem areas for the cable operator.
