Methods and devices for encoding high-definition signals by computing selection algorithms and recording in an off-line manner
First Claim
1. An improved process for modifying a first motion picture sequence utilizing a digital processing unit of a particular computational capacity, wherein the improvement comprises applying the following steps to each image of a multiplicity of images of said first motion picture sequence to create a multiplicity of images comprising a second motion picture sequence:
- a. inputting into said digital processing unit an image of said first motion picture sequence as a first array of digital data; and
,b. processing said first array of digital data by said digital processing unit to create a second array of digital data of reduced information content, wherein said processing is accomplished by an algorithm operating as software on said digital processing unit, and wherein the operation of said algorithm requires more computational capacity than available from said digital processing unit in order to accomplish said operation in the time allotted to an image of said second motion picture sequence during standard display at standard temporal resolution and, thus, said processing is accomplished in a time longer than said time allotted.

Abstract
Off-line computation and recording is applied (via an under-powered processor) to the encoding, for bandwidth compression, of a high-resolution video signal. This technique permits more compute cycles to be applied to each frame than if the process were attempted to be accomplished in real time. Better compression ratios and/or better visual quality are, thus, achieved than if the process were attempted to be performed by the same processor in a real-time manner.
