Abstract
Abstract A video signal receiver receives a plurality of video channels simultaneously carrying, offset by a transmission interval, a single video program, selects one channel from which to obtain the program for display to a user, and achieves a pause function in the display of the transmitted video program by temporarily storing a segment of the video program equal to the length of the transmission interval and obtaining the remainder of the program at a later time from the same or another channel.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
295 words
A video signal receiver for receiving a plurality of video channels simultaneously carrying a single video program comprised of video signals, each transmission of said video program on one of said channels being offset by a time interval with respect to the transmission of said video program on another one of said channels, comprising: memory means for receiving video signals for storage and reproducing stored video signals; preview storage means for storing video signals representing previews of a plurality of video programs and for storing a first segment of each of said plurality of video programs; channel selecting means, coupled to said memory means, for selecting one of said video channels and for supplying the video signals carried on the one channel to said memory means; user input means for providing commands from a user; and control means, coupled to said memory means, said channel selecting means and said user input means, for controlling said preview storage means, in response to a preview command received from said user input means, to reproduce said video signals representing previews of a plurality of video programs, for controlling said preview storage means, in response to a select command received from said user input means, to reproduce the first segment of a selected video program which includes a segment end video signal, for determining a next channel that is next to carry said segment end video signal, for controlling said channel selecting means to supply the video signals carried on said next channel to said memory means, for controlling said memory means to store the video signals carried on said next channel as a stored segment, and for controlling said memory means to reproduce said stored segment after said preview storage means has reproduced said segment end video signal.
Claim 2
Dependent Claim

A video signal receiver for receiving a plurality of video channels simultaneously carrying a single video program comprised of video signals, each transmission of said video program on one of said channels being offset by a time interval with respect to the transmission of said video program on another one of said channels, comprising: memory means for receiving video signals for storage and reproducing stored video signals; preview storage means for storing video signals representing previews of a plurality of video programs and for storing a first segment of each of said plurality of video programs; channel selecting means, coupled to said memory means, for selecting one of said video channels and for supplying the video signals carried on the one channel to said memory means; user input means for providing commands from a user; and control means, coupled to said memory means, said channel selecting means and said user input means, for controlling said preview storage means, in response to a preview command received from said user input means, to reproduce said video signals representing previews of a plurality of video programs, for controlling said preview storage means, in response to a select command received from said user input means, to reproduce the first segment of a selected video program which includes a segment end video signal, for determining a next channel that is next to carry said segment end video signal, for controlling said channel selecting means to supply the video signals carried on said next channel to said memory means, for controlling said memory means to store the video signals carried on said next channel as a stored segment, and for controlling said memory means to reproduce said stored segment after said preview storage means has reproduced said segment end video signal.
Claim 3
Dependent Claim
33 words
Receiver according to claim 1, wherein said memory means simultaneously stores the video signals carried on said next channel and reproduces the stored video signals that had been carried on said next channel.
