Abstract: Systems, devices and methods are provided to support multiple audio tracks in an adaptive media stream. Segments of the adaptive stream are encoded so that the player is able to locate and request a specific one of the available audio tracks using byte range requests or the like. Audio content can be removed from video segments, or at least moved to the end of the segments so that a byte range request obtains just the video content when the default audio is not desired. The audio content can be obtained from a separate audio segment. Indeed, multiple audio tracks can be packaged into a common audio segment so that byte range requests can obtain just the particular audio track desired.

Abstract: A content reproduction apparatus that adopts a content processing method includes a video processor, a video analyzer, and an audio processor for processing audio data and video data input thereto. The video analyzer analyzes video characteristics of video data such as resolutions, compressive distortions, and real frame rates. The video processor processes video data in accordance with video processing, which is determined based on analyzed video characteristics of video data. The audio processor processes audio data in accordance with audio processing, such as dynamic range compression and/or frequency component extension/enhancement, which is determined based on analyzed video characteristics of video data. Thus, it is possible to reproduce sound in an articulate manner depending on the video quality, which is either professional-level video shooting or nonprofessional-level video shooting.

Abstract: When multi-frame rate contents including many high frame-rate portions are played back in a video player, a playback can be easily selected by showing to a user a playback time in respective playback modes of a normal playback and a slow playback. The video player includes a rate analysis unit for calculating playback time in the respective playback modes by analyzing a frame rate of multi-frame rate contents, and thumbnail images of multi-frame rate contents and playback time in the respective playback modes are listed and displayed as display units in a pair with respect to a plurality of contents.

Abstract: One of a plurality of video channels is selected for viewing. A specific one of a plurality of video channels is bookmarked. An object representing said bookmarked channel is displayed. A displayed object is selected to select the bookmarked channel.

Abstract: Systems and methods to modify playout/playback include responding to a trick mode request (e.g., fast forward, rewind). First, a transmission is received at a receiving device. The transmission includes primary content and a secondary information identifier and is stored on a storage device. Next, primary content is rendered to an output device at the receiving device at a normal speed for the primary content. Next, a request is received to render the primary content to an output device at the receiving device at an accelerated speed of the primary content. Next, the primary content is associated to secondary derivative content based on the secondary information identifier. Finally, the secondary derivative content is rendered instead of the primary content, to the output device at the receiving device at a normal speed for the secondary derivative content.

Abstract: A storage medium for storing text-based subtitle data including style information, a reproducing apparatus and methods are provided for reproducing text-based subtitle data including style information separately recorded on the storage medium. The storage medium includes: multimedia image data; and text-based subtitle data for displaying subtitles on an image based on the multimedia image data, wherein the text-based subtitle data includes dialog information indicating subtitle contents to be displayed on the image, style information indicating an output style of the dialog information, and partial style information indicating an output style applied to a portion of the dialog information. Accordingly, subtitles can be provided in a plurality of languages without limited to the number of units of subtitle data. In addition, subtitle data can be easily produced and edited. Likewise, an output style of the subtitle data can be changed in a variety of ways.

Abstract: A recording apparatus includes first identification means for identifying, in accordance with information read from a disk medium and related to a format of data recorded on the disk medium, the format defined from a purpose of the recorded data and a version of the format; storage means for storing data in which the version and information on whether processing that can be executed is executable are associated; determination means for determining, in accordance with the version and by referring to the data stored in the storage means, whether processing that can be executed is limited; generation means for generating first image data for displaying a first image representing that the processing that can be executed is limited when the determination means determines that the processing that can be executed is limited; and display control means for controlling display of the first image in accordance with the first image data.
