Abstract

Abstract System for distributing video programs includes a transmission system having a plurality of channels, includes a stored database representing a predetermined schedule including timing instructions. A computer is programmed to provide real time outputs in response to the database time instructions. A bus has an input coupled to the computer and providing control signals in response to the real time outputs. A recorded media contains programs in television format. A plurality of video players are used for playing the recorded media, each video player having a control port coupled to the bus and responsive to the control signals. Each video player has an output providing television signals for coupling to a separate corresponding channel, and at least two of the video players loaded with duplicate recorded media and controlled to play at staggered overlapping time intervals. A character generator is coupled to the computer for providing to a channel a menu in television format representing a programming schedule. Scrambling means are interposed between the output of a video player and the corresponding channel for scrambling the television signal. Access means provides downstream access to a channel and unscrambles a television signal on an accessed channel. The access means provides access to the first and second channels thereby allowing return to the same point of a program after a pause equal to the staggered time interval.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 181 words
A system for distributing video programs over a plurality of channels comprising: a transmission system having a plurality of channels; a stored database storing a predetermined schedule including timing instructions; a computer programmed to provide real time outputs in response to said database time instructions; a bus having an input coupled to said computer and conveying control signals in response to said real time outputs; recorded media containing programs in television format; a plurality of video players for playing said recorded media, each video player having a control port coupled to said bus and responsive to said control signals, each video player having an output providing television signals coupled to a separate corresponding channel, at least two of said video players loaded with duplicate recorded media and controlled to play at staggered overlapping time intervals on first and second channels; and access means for providing downstream access to a channel, wherein said access means provides access to said first and second channels thereby allowing return to the same point of a program after a pause equal to said staggered time interval.
Claim 2
Independent Claim 181 words
A system for distributing video programs over a plurality of channels comprising: a transmission system having a plurality of channels; a stored database storing a predetermined schedule including timing instructions; a computer programmed to provide real time outputs in response to said database time instructions; a bus having an input coupled to said computer and conveying control signals in response to said real time outputs; recorded media containing programs in television format; a plurality of video players for playing said recorded media, each video player having a control port coupled to said bus and responsive to said control signals, each video player having an output providing television signals coupled to a separate corresponding channel, at least two of said video players loaded with duplicate recorded media and controlled to play at staggered overlapping time intervals on first and second channels; and access means for providing downstream access to a channel, wherein said access means provides access to said first and second channels thereby allowing return to the same point of a program after a pause equal to said staggered time interval.
Claim 3
Dependent Claim 33 words
The system of claim 1 further comprising a character generator coupled to said computer and having an output coupled to a channel for providing a menu in television format representing a programming schedule.
Claim 4
Dependent Claim 29 words
The system of claim 2 further comprising at least one promotional video player for playing promotional programming, said promotional video player having an output coupled to a promotional channel.
Claim 5
Dependent Claim 71 words
The system of claim 3 further comprising a character generator coupled to said computer and having an output coupled to a channel for providing a menu in television format representing a programming schedule and coupled into the input of the promotional video player, arranged so that if said one or more promotional video players are in a non-play condition, then the character generator output is automatically connected into the promotional channel.
Claim 6
Dependent Claim 45 words
The system of claim 1 further comprising scrambling means interposed between an output of a video player and said corresponding channel for scrambling said television signal, and wherein said access means unscrambles a television signal on an accessed channel in accordance with an enabling signal.
