Abstract: Determining and hiding a replaceable period of a MP (Media Presentation). A method for determining includes receiving a first MPD (Media Presentation Description) that identifies a predetermined period and at least one media segment of the MP to be presented during the predetermined period. A determination is made as to whether the first MPD includes additional data to be resolved by an application. The additional data is provided to the application when the first MPD is determined to include the additional data. Additional period information is received from the application. A second MPD is generated based on the received additional period information. The MP is output for display to a user based on the second MPD. Each of a subset of the at least one media segment for a replaceable sub-period of the MP is replaceable with an alternate media segment.

Abstract: A method of decoding closed caption disparity data, involves a TV receiver receiving closed caption disparity data for a 3D display encoded as a sequence of frame interval/slope change pairs, with the frame interval representing a designated number of frames over which each linear function representing disparity is to be applied paired with a value indicating a change in slope from the slope of a preceding segment. A first segment in the sequence presumes a predetermined slope as a reference. A sequence of caption data packets specifies a closed caption display window containing closed caption text. The disparity value is used in each frame to determine a horizontal offset of left and right eye views of the CC display that establishes the closed caption display window's perceived z-axis position. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
