Abstract
Abstract An improved recording format for a video disc is disclosed in which only one of the video frames of a consecutive plurality of frames is recorded. The sound corresponding to the recorded video frame and the omitted video frames is multiplexed and written with the recorded frame. On playback, the recorded frame is repeated a sufficient number of times to substitute for the omitted frames and each repeat is accompanied by the sound corresponding to the omitted frames in proper sequential order. A method of achieving this format in a circular or spiral track configuration is disclosed.

Claim 1
Independent Claim
107 words
The method of making an extended play video disc record comprising the steps of: a. receiving at least two complete sequential video program standard increments; b. extracting the audio portion from said received video program standard increments; c. storing at least one of the extracted audio portions; d. combining a first audio portion with subsequent audio portions; and e. continuously recording the video portion of only one of said received video program standard increments together in simultaneity with the combined audio portions of all of the received video program standard increments, without altering said video program standard increments or the sync or blanking intervals normally associated therewith.
Claim 2
Independent Claim
107 words
The method of making an extended play video disc record comprising the steps of: a. receiving at least two complete sequential video program standard increments; b. extracting the audio portion from said received video program standard increments; c. storing at least one of the extracted audio portions; d. combining a first audio portion with subsequent audio portions; and e. continuously recording the video portion of only one of said received video program standard increments together in simultaneity with the combined audio portions of all of the received video program standard increments, without altering said video program standard increments or the sync or blanking intervals normally associated therewith.
Claim 3
Independent Claim
147 words
The method of making an extended play video disc record comprising the steps of: a. receiving X complete video program standard increments; b. extracting the audio information portion from said X video program standard increments; c. storing the extracted audio information portions; d. receiving a next, sequential video program standard increment; e. extracting the audio information portions from said next sequential video program standard increment; f. combining the stored audio information portion from said X video program standard increments with the audio information portion from said next video program standard increment; and g. continuously recording said next sequential video program standard increment simultaneously with the combined audio information portions from said X video program standard increments and said next video program standard increment, without altering or modifying said next video program standard increment or the sync or blanking intervals normally associated therewith, where X is an integer.
