Abstract: PROBLEM TO BE SOLVED: To reproduce and display an animation graphic including video or audio by providing a step or the like for displaying the audio, video and graphic unit in a tandem system inside a hall together with multimedia presentation. SOLUTION: It is discriminated whether control information including a 'hall' position arrives together with the presentation or not (S81). When that information arrives, a demultiplexer reference is setup so as to receive it (S82). Then, it is discriminated whether control data arrives by the demultiplexer reference or not (S83) and when that information arrives with that reference, it is analyzed for confirming an HTML tag (S84). Then, the HTML tag is collated with the 'hall' information (S85). When there is coincidence, the hall information is extracted and the audio, video and graphic unit are displayed by the tandem system inside the hall of multimedia presentation together with the multimedia presentation (S86).

Abstract: A method for displaying an enhanced multimedia presentation including personalized supplementary audio, video, and graphic content selectable by a user and rendered by a receiving device, comprises the steps of: communicating a multimedia presentation file to the receiving device, the multimedia presentation file comprising base multimedia presentation content and, frame-synchronized information including starting frame timing identifier, ending frame timing identifier, starting frame spatial coordinates, ending frame spatial coordinates, and motion vector specifications for describing frame-accurate location, motion and timing of the personalized supplementary audio, video, and graphic content, the frame-synchronized information indicating one or more free areas of the multimedia presentation absent significant base multimedia content; extracting the frame-synchronized information from the multimedia presentation file; retrieving the personalized supplementary content from the receiving device; decoding the personalized supplementary content at a time sufficiently in advance of the starting frame timing identifier; and the receiving device selecting an indicated free area and initiating display of one or more items of the personalized supplementary content at frame-accurate times between the starting frame timing identifier and ending frame timing identifier at the frame coordinates in accordance with the frame-synchronized information.
