User request processing method and apparatus using upstream channel in interactive multimedia contents service
First Claim
1. A user request processing method, using an upstream channel, after a three-dimensional scene generated based on a binary format, is transmitted from a server to a terminal, the user request processing method comprising the steps of:
- (a) setting downstream/upstream channels between the server and the terminal as initialization;
(b) the terminal forming an upstream channel message if a user request of predetermined processing of a predetermined object is occurred in a scene transmitted from the server to the terminal through the downstream channel, and transmitting the message to the server through the upstream channel;
(c) the server receiving the upstream channel message, interpreting the message, processing the message as the user request of predetermined processing, and transmitting the result to the terminal; and
(d) the terminal substituting the processing result of step (c) for the predetermined object in the scene transmitted in step (b), and providing it to the user.

Abstract
A user request processing method and apparatus, using an upstream channel, is provided, in which if a user request of predetermined processing for some predetermined nodes in interactive multimedia contents services, preferably, in an MPEG-4 binary format for a scene (BIFS) scene occurs, the user terminal forms an upstream channel message for the BIFS scene and transmits the message to the server through upstream channels, and the server processes and encodes the corresponding BIFS scene nodes and then transmits the nodes to the terminal. According to the methods and apparatuses, by properly handing events of user requests on partial elements in an arbitrary multimedia content provided for the user as interactive multimedia contents services, predetermined elements can be selectively processed. Therefore, information volume to be transmitted for restoration from an error can be minimized, and the terminal can quickly receive restored information.
