A multimedia file and methods of generating, distributing and using the multimedia file are described. Multimedia files in accordance with embodiments of the present invention can contain multiple video tracks, multiple audio tracks, multiple subtitle tracks, a complete index that can be used to locate each data chunk in each of these tracks and an abridged index that can enable the location of a subset of the data chunks in each track, data that can be used to generate a menu interface to access the contents of the file and meta data concerning the contents of the file. Multimedia files in accordance with several embodiments of the present invention also include references to video tracks, audio tracks, subtitle tracks and meta data external to the file. One embodiment of a multimedia file in accordance with the present invention includes a series of encoded video frames, a first index that includes information indicative of the location within the file and characteristics of each encoded video frame and a separate second index that includes information indicative of the location within the file of a subset of the encoded video frames.

Logging events in a media file, including: providing a logger tool to allow a user to view media in multiple ways and to capture and validate key events within the media file; and tracking and logging events in the media file by adding information to the media file including locations of bars and tone, slates, content, logos, commercial blacks, quality control issues, subtitles, and captions.

Preferred placement of programming content is provided by a system and method to organize or sequence the display of a set of programmable content elements of an iTV application to a viewer, using business rules that describe the preferred placement conditions or criteria. Such criteria include brand, content owner, application location, current channel, current channel family, current channel category, time of day, content category, current program, current program genre, current iTV application, current content type, and/or subscriber and set-top box profile and behavior data. In one implementation, the present invention allows for managing the shelf space within and for iTV applications.

A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.

A method, computer program, and reception apparatus, and information providing apparatus. The method includes receiving a trigger parameters table (TPT). The TPT is associated with a triggered declarative object (TDO) and includes at least one parameter associated with a trigger event. The TPT is stored in a first memory of the reception apparatus. The TDO is executed by a processor of the reception apparatus and is stored in a second memory of the reception apparatus. The reception apparatus receives a trigger associated with the trigger event. At least one parameter associated with the trigger event is retrieved from the TPT based on information included in the trigger. Further, a function is performed based on the retrieved at least one parameter.

The present disclosure relates to a content supply device, a content supply method, a program, a terminal device and a content supply system that are configured to be capable of realizing rapid zapping between channels in DASH. The content supply device of the present disclosure supplies a plurality of items of streaming data with differing attributes, which is content with identical detail, to the same channel, and is provided with a supply portion that divides the streaming data into minimum units when the reception of streaming data is switched according to a timing that is made uniform with other channels, and supplies the streaming data to a reception side through a network, and a metafile generation portion that generates metafiles for the reception side to receive the streaming data that is supplied in the minimum units, which show that the streaming data is for zapping. The present disclosure can be applied to a system that performs streaming distribution of content.

An approach for creating a clickable link within a presentation during a live collaborative web meeting is provided. The approach identifies one or more uniform resource locators within the presentation. The approach retrieves metadata for each of the one or more uniform resource locators within the presentation. The approach presents the metadata for each of the one or more uniform resource locators with a corresponding image from the presentation. The approach creates the clickable link for each of the one or more uniform resource locators with the corresponding image.

Multiple different versions of media content are contained in a single package of audio-video media content, using compression algorithms that reduce storage and bandwidth required for storing multiple full-resolution versions of the media. Portions of individual frames are replaced during playback so that only the pixels that differ between versions need to be stored.

A method and system for providing video content on a data network connected device having a display and a device display controller including a player. The method comprises the steps of a data network connected device, accesses a reference file including a plurality of player control parameter values and linking data for one or more content sources. Play control commands are provided to the player based on the play control parameter values. Content data is acquired by the player from one or more content sources via the data network using the linking data, and the content acquired from each source played on the display in accordance with the player control commands. The reference file may be a pre-existing reference file or a reference file created in response to a request to play the video content data. A reference file compiler is provided for generating the reference file.
