Television program multi-mode film examination method achieving one-key control

Abstract

The invention discloses a TV program multi-mode screening method realizing one-button control. Existing film review technology requires the cooperation of professional technicians to complete the review of the entire program step by step according to the review requirements one by one. The present invention includes the following steps: Step (1). Definition of the review mode; Step (2). Physical connection of the review device; Step (3). One-key touch switching; first touch and click the review mode to read the review mode slice mode configuration information; secondly according to the type of screen signal source, the number and type of video signal source, the number and type of audio signal source in the configuration information to realize switching after judging; step (4). signal source name tracking; step (5). Check the subjective and objective review results. The invention realizes equipment diversity control; can achieve "one-key trigger" type simple operation; has rich interfaces of film review equipment, and simultaneously realizes accurate cascading operation of multiple video recorders.
