SYSTEMS AND METHODS FOR PROCESSING TIMED TEXT IN VIDEO PROGRAMMING

摘要

Systems, devices and methods are described to process timed text that is associated with media or other video programming. Pre-set data that describes the particular format of the timed text that is associated with a program is initially received and stored at the media receiver prior to receiving the program with encoded timed text. The timed text that is associated with the received program is interpreted according to the pre-set data previously stored at the media receiver, and the program with the interpreted timed text is output to a display for presentation to the viewer.

主权项

1. A method executable by a media playback device to process timed text that is associated with media programming, the method comprising:
receiving, at the media receiver, a broadcast signal comprising pre-set data associated with a particular program, wherein the pre-set data provides a priori knowledge about the particular format of the timed text that is part of the particular media program, wherein the pre-set data is received at the media receiver separately from the particular media program; storing the pre-set data at the media receiver prior to receiving the particular media program at the media receiver; after storing the pre-set data, the media receiver receiving the particular media program and its associated timed text; formatting the received timed text associated with the received program according to the previously-received pre-set data describing the particular format of the timed text that was previously stored at the media receiver to thereby combine the interpreted timed text with the received program; and outputting the particular media program and its associated interpreted timed text to a display for presentation by the media playback device.
