Multiple channel CATV system utilizing row grabber interface as CATV input

摘要

An improved multichannel CATV type television system includes a real time frame grabbing system for substantially instantaneously providing a selectable continuous video displayable frame of video information to a video interface, such as a row grabbing terminal, for providing a preselected continuous video displayable frame of the information to at least one of the channels as the video information content thereof from continuously transmittable information. The row grabbing terminal receives this information in the form of a plurality of pseudo video scan lines and processes the composite pseudo video scan lines for providing a video displayable row from each of the pseudo video scan line signals pertaining to the preselected frame for providing a selected continuous video displayable frame of dedicated information to a given channel. Normal CATV television signals may be provided to one or more of the other channels wherein the CATV subscriber may receive dedicated common channels of preselected frame grabbable information on normal television signal CATV channels over the CATV television signal distribution network while also receiving conventional CATV television programs. Local video editing of the frame grabbable information may be accomplished and interleaved with a remote pseudo video scan line signal source for providing composite combined interleaved pseudo video scan line signals comprising the preselected grabbed frame.
