Disc record with skipped standard video increments and continuous audio increments and a method and apparatus for reproduction

Claim 2

An extended play video disc record comprising: a disc member having a substantially planar disc surface with variable characteristics portions representing a standard increment of video information recorded thereon, and including more than one standard increment of audio information recorded simultaneously therewith, said variable characteristics portions being discontinuities out of the plane of the surface corresponding to information, said discontinuities being generally disposed in a substantially circular path, each discontinuity having a constant dimension in the radial direction and a constant maximum dimension in the direction perpendicular to said surface, the length of each discontinuity in the circumferential direction and the distance between adjacent discontinuities in the circumferential direction representing the stored information and collectively forming a plurality of mutually spaCed information tracks extending circumferentially around the disc, representing an ordered, segmented video program, whereby each standard increment of video information is adapted to be read more than once, each time with a different audio information standard increment to provide a continuous program presentation.

Claim 3

The video disc of claim 1, above, wherein each video program standard increment is a frame and each information track has recorded thereon the video information of only alternate frames of a transmission and recorded simultaneously therewith the audio information of the recorded frame and the audio information of an adjacent, omitted frame.

Claim 4

The video disc of claim 1, above, wherein the information track is arranged in a plurality of concentric circles, each containing a complete video information standard increment.

Claim 5

The video disc record of claim 1 wherein each 360* of information track has recorded thereon a sequential video program information increment and at least two audio information increments, whereby a sequential plurality of said tracks has a video program segment recorded thereon, including only alternate video increments together with audio increments corresponding to omitted video increments of the program segment.

Claim 6

The video disc of claim 1, above, wherein the information tracks are arranged in a continuous spiral, each turn containing a complete video information standard increment.

Claim 7

The video disc record of claim 1 wherein a first 360* of track has one of X successive video signal information standard increments and the X successive audio information standard increments associated therewith recorded thereon, the next successive sequential track having one of the next X video signal information standard increments and the X successive audio information standard increments associated therewith recorded thereon, whereby only one of every X successive video signal information standard increments with all of the audio standard increments is recorded where X is an integer greater than 1.

Claim 8

The video disc of claim 6, above, wherein each video signal information standard increment has recorded simultaneously therewith the audio information standard increments associated with X video signal standard increments.

Claim 11

The method of claim 8, above, wherein the extended play video disc has the audio increments from an omitted video increment combined with the video and audio of a selected increment, further including the steps of g. reading the next recorded video program increment; and h. repeating steps (b) through (f).

Claim 12

Apparatus for playing back an extended play video disc record having a substaNtially planar surface and having discontinuities out of the plane of the surface corresponding to information, said discontinuities being arranged in mutually spaced information tracks in a substantially circular path, each discontinuity having a constant dimension in the radial direction and a constant maximum dimension in the direction perpendicular to said planar surface, the length of each discontinuity in the circumferential direction representing stored information the stored information comprising selected standard video increments recorded threon each combined with more than one accompanying audio increment, said apparatus comprising the combination of: a. first means for reading a recorded standard video increment; b. second means coupled to said first means for selectively extracting a first audio increment from said recorded standard video increment; c. third means coupled to said first and second means for combining said standard video increment with said first audio increment for application to a utilization device; and d. fourth means coupled to said first means for repeating said recorded standard video increment on said repeat playback, whereby a second audio increment is extracted from said recorded video increment and combined with the repeated video increment for application to the utilization device.

Claim 13

Apparatus for playing back an extended play video disc record having a substaNtially planar surface and having discontinuities out of the plane of the surface corresponding to information, said discontinuities being arranged in mutually spaced information tracks in a substantially circular path, each discontinuity having a constant dimension in the radial direction and a constant maximum dimension in the direction perpendicular to said planar surface, the length of each discontinuity in the circumferential direction representing stored information the stored information comprising selected standard video increments recorded threon each combined with more than one accompanying audio increment, said apparatus comprising the combination of: a. first means for reading a recorded standard video increment; b. second means coupled to said first means for selectively extracting a first audio increment from said recorded standard video increment; c. third means coupled to said first and second means for combining said standard video increment with said first audio increment for application to a utilization device; and d. fourth means coupled to said first means for repeating said recorded standard video increment on said repeat playback, whereby a second audio increment is extracted from said recorded video increment and combined with the repeated video increment for application to the utilization device.

Claim 14

Apparatus of claim 10, above, wherein said fourth means include means responsive to synchronization signals in said video increment for generating gating signals; said second means being operable in response to applied gating signals for selectively extracting first and audio increments.
