    摘要: A system for scrambling a video signal, wherein multiple modes of scrambling are available, including (i) line reversal, (ii) line inversion, (iii) line permutation, and (iv) block permutation. The invention changes the combination of modes used as time progresses. In addition, particular modes can be implemented, or suppressed, in response to such factors as (i) noise in the transmission channel and (ii) amount of motion within the video image.

    摘要: A system for including audio data within a video signal. The number of frames of video data transmitted is reduced, thereby allowing greater time for each individual frame, thereby allowing the breezeway of each line of each frame to be lengthened. The breezeway resides between the horizontal synch pulse for the line, and the color burst signal. Samples of digitized audio are placed into the breezeways.

    摘要: A system wherein audio samples are added to a video signal, but within the time-frame allocated to video information, thereby displacing video data. Two audio samples are preferably placed in each video line: at the beginning, and at the end. When the video lines are "stacked" to form a video image, the audio forms noisy vertical stripes at the sides of the image, each of which is about 6 percent of the width of the image. The invention stretches the video image, to cover the stripes.
