Method for semantics based trick mode play in video system

摘要

Trick mode play for controlling video content playback can be realized using a semantic based criterion in order to achieve a more uniform playback experience for the viewer, when that viewer wishes to observe the video content presented according to a selected semantic. In one embodiment of the method, semantics associated with shorter time intervals in the video content are replayed in trick mode play proportionally slower than semantics associated with longer time intervals, wherein the proportionally is determined, at least in part, to the time interval associated with each semantic. In various embodiments, semantics can include scenes, audio, metadata, tags, and the like. The semantics based trick mode play approach allows for a more uniform viewing experience, on a time duration basis, from one semantic to the next.

1. A method for controlling replay for video content in a trick mode of operation, the method comprising:
receiving a trick mode command; determining a trick mode frame rate as a function of a time interval between consecutive semantics in the video content, a time duration of the video content, a number of occurrences for the semantics in the video content and a frame rate in a normal play mode of the video content; and wherein the video content related to the time interval in the trick mode defined by the received trick mode command is displayed at the trick mode frame rate, said trick mode frame rate, Vi, is determined as Vi=[Ti/T]×(N×L×M), where Ti is a time interval between an ith and an (i+1)th consecutive semantics in the video content, T is a time duration of the video content, N is a number of occurrences for the semantics in the video content, and M is a frame rate in a normal play mode.
