Applying a presentation timestamp to an element of a sequence of sub-titles. A minimum presentation timestamp T.sub.MIN of an element of a sequence of sub-titles N is initialized. The presentation timestamp T(N) of the new element of a sub-title sequence N is compared with the minimum presentation timestamp for sub-titles T.sub.MIN. The minimum presentation timestamp for sub-titles T.sub.MIN is applied to the element of a sequence of sub-titles N if the presentation timestamp T(N) of the new sub-titles element is prior to the minimum presentation timestamp for sub-titles T.sub.MIN. The minimum presentation timestamp for sub-titles T.sub.MIN for an element of a sequence of sub-titles N+1 is calculated as a timestamp posterior to the presentation timestamp T(N) of the new sub-titles element.

An interactive video/multimedia application (IVM application) may specify one or more media assets for playback. The IVM application may define the rendering, composition, and interactivity of one or more the assets, such as video. Video multimedia application data (IVMA data may) be used to define the behavior of the IVM application. The IVMA data may be embodied as a standalone file in a text or binary, compressed format. Alternatively, the IVMA data may be embedded within other media content. A video asset used in the IVM application may include embedded, content-aware metadata that is tightly coupled to the asset. The IVM application may reference the content-aware metadata embedded within the asset to define the rendering and composition of application display elements and user-interactivity features. The interactive video/multimedia application (defined by the video and multimedia application data) may be presented to a viewer in a player application.

A system and method for insertion of one or more advertisement assets into a source dynamic video. The method includes: determining a media format of each of the one or more advertisement assets; converting each of the media formats for each of the one or more advertisement assets for compatibility with a dynamic media format of the source dynamic media; selecting a portion of a timeline of the source dynamic media for each of the advertisement assets; blending the one or more advertisement assets into the source dynamic media during the respective determined portion of the timeline; encoding the source media and the blended one or more advertisement assets as a combined dynamic media; and outputting the combined dynamic media.

Apparatus for generation of playable media from structured data, comprises a structured data reading unit for reading in of content of a first structure, a transformation unit for transforming said content into a second structure, said transformation comprising incorporating media play instructions, and a rendering unit for rendering content from the second structure using said media play instructions to generate playable media from the content.

A content management system (CMS) for graphically authoring and deploying a television app and pages for access and display by end user devices. The CMS displays a canvas in a GUI and receives input graphically specifying page appearance using a component on the canvas. The component is compatible for rendering in a webpage format and in a television app page format. The webpage format of the component is used for rendering the component on the canvas. The CMS deploys the page so it can be rendered in either the television app page format or the webpage format depending upon which type of page is requested. The CMS can also enable authoring and deploying configuration information and application logic that is accessed by a shell app on the end user devices.
