A video system for processing compressed video data into composite video data, the composite video data corresponding to a standard composite video signal type selected from a plurality of standard types, the plurality of standard types including at least one of an NTSC composite video signal type and a video signal type, includes a processor, a standard video decompressor and a video interface. The standard video decompressor processes the compressed video data into decompressed video data and user data, the user data having VBI data encoded therein. The processor culls the VBI data from the user data. The video interface processes the decompressed video data and the VBI data into the composite video data with the VBI data encoded therein. The video interface includes a VBI data generator to process the VBI data into VBI signal data, a mixer coupled to the video decompressor to receive the decompressed video data, the mixer being coupled to the VBI data generator to receive the VBI signal data the mixer providing output Y, U and V data during an active portion of a scan line, and circuitry to process the Y, U and V data into the composite video data.

System and method for transmitting a plurality of digital services

A cable television interdiction apparatus comprises a microprocessor actuation and control means for actuating and controlling one or more frequency agile voltage controlled oscillators. The voltage controlled oscillators selectively jam only unauthorized premium programming transmitted from a headend to a particular subscriber. The method of interdiction comprises the steps of generating and storing voltage control words for operating the oscillators consistent with a headend selected jamming factor for a particular channel to be jammed and addressably transmitted and stored premium programming authorization data.

Interdiction method and apparatus with variable dwell time

An apparatus for providing close captioning in a digital program services delivery system comprises: a rate converter circuit for receiving video codes and outputting video data; a video decoder circuit for receiving the video data and outputting digital Y, U, V data; a digital to analog converter/analog encoder circuit for converting the Y, U, V data into an analog video signal in a prescribed format; a line 21 former circuit for receiving close captioning digital data and forming a line 21 analog signal; and a multiplexor for inserting the line 21 analog signal into the analog video signal.

Apparatus and methods for providing close captioning in a digital

Digital image data compression apparatus includes a controller circuit for receiving digital image data and for processing the image data into blocks. The controller circuit supplies processed image data to a plurality of transform circuits and to a feeder circuit. The transform circuits receive data from the controller circuit and the feeder circuit, and provide parallel processing to compare blocks of image data and generate fractal transform values representing the image data in a compressed form.
