Audio-visual flow and information e.g. sub-titles, delivering method for film/video subtitling field, involves delivering portion of information flow relating to reference flow samples, if instance and reference flow samples are equal

摘要

The method involves obtaining an instance digital flow from delivered audio-visual flow relative to a film (3). The instance digital flow is of same type as a reference digital flow. Samples from recent instance flow are compared with samples of the reference flow. A portion of stored information flow corresponding to samples of the reference flow is delivered in time, when the samples of the instance and reference flows are equal. An independent claim is also included for a system of delivering an audio-visual flow and information.
