[0049] In the first embodiment of the present invention, a method for providing a structured rich media UI is firstly described using a basic rich media UI format. Table 2 shows the rich media UI format.
[0050] Table 2
[0051]
[0052] Referring to Table 2, the rich media UI format consists of header and scene data. The UI node, which is the highest node, may include the ID of the rich media UI, version information, and horizontal and vertical lengths. The UI node is structured as . The header may include additional information as shown in Table 3.
[0053] table 3
[0054]
[0055] In Table 3, the header of the rich media UI includes initial information, configuration information, and layout information. Initial information and configuration information can be combined into a single configuration information element. The configuration information may be formed as data separate from the rich media interface format and referenced in the original i...

[0083] In the second embodiment of the present invention, a scene presentation method in rich media UI format is described, wherein LASeR is a rich media scene presentation technology.
[0084] figure 2 It is a flowchart illustrating a rich media UI processing method of a receiving terminal according to the second embodiment of the present invention.
[0085] refer to figure 2 , the receiving terminal receives service content in step 200 and decodes the received service content in step 210 . After decoding the service content, the receiving terminal checks the header of the decoded UI information to acquire basic information for rendering the UI at step 220 . The receiving terminal then checks the UI command at step 230 . The step of checking UI commands can be skipped depending on the format of the data. The receiving terminal checks the rich media data of the UI and provides the rich media data to the rich media engine. The rich media engine analyzes the rich m...

[0090] LASeR content can be served in the form of multiple logical media streams multiplexed into one physical stream. Simple Aggregation Format (SAF) is a format for multiplexing and synchronizing LASeR Elementary Streams (ES). Each stream can be processed in an access unit (AU). An AU is a basic unit of data processed at one time when serving LASeR content (or stream) in a multiplexed format. The structured rich media UI format created at the transmitting terminal can be transmitted in the form of SAF stream. Such as image 3 The receiving terminal shown processes the SAF stream.
[0091] image 3 It is a flowchart illustrating a rich media UI processing method of a receiving terminal according to the third embodiment of the present invention.
[0092] refer to image 3 , the receiving terminal receives the service data stream at step 310 and decodes the received service data stream at step 320 . The receiving terminal identifies the decoded SAF stream at ste...
