Abstract

PURPOSE: A system for providing a download type multimedia service in a wireless communication network, and a method thereof are provided to realize various user interfaces by freely downloading user interfaces and codecs according to selection of a user. CONSTITUTION: A subscriber of a wireless terminal selects a wanted UI(User Interface) by using a platform player included in the wireless terminal(S201). The selected UI is downloaded to the wireless terminal from a UI providing unit(S202). The wireless terminal executes the corresponding UI and selects wanted multimedia contents for downloading the multimedia contents(S203,S204). The wireless terminal confirms a codec necessary for playing the downloaded multimedia contents, and judges whether the codec is to be downloaded(S205,S206). If so, the wireless terminal searches for the necessary codec and requests the codec to download the codec(S207,S208). The wireless terminal plays the corresponding multimedia contents(S209).

Description

System and method for providing downloadable multimedia service in wireless communication network {System and method of download form multimedia service in mobile communication network}

The present invention relates to a method for providing multimedia content through a wireless terminal in a wireless communication network. In particular, when using a multimedia service, a download-type multimedia service providing system in a wireless communication network enables a service by using an integrated user interface. And to a method.

Currently, in order to perform a multimedia service in a terminal such as a wireless terminal or a PDA (Personal Digital Assistant) in a wireless communication network, a separate codec and player suitable for the corresponding content should be mounted.

To this end, a method of downloading and driving a user interface and a new codec suitable for a specific service when using a multimedia service using a wireless terminal is used.

In this conventional method, a different user interface is set in a terminal according to each service provider, and the codec also stores only a few kinds of codecs necessary for multimedia contents that can be provided by a service provider during terminal manufacturing.

Therefore, it is difficult for subscribers to certain service companies to use the multimedia contents provided by other service companies, and even if the subscribers access the service companies to which they subscribe, the multimedia contents are provided in various formats due to the limitation of the number of codecs stored in the wireless terminal. There is no use of multimedia content.

In addition, even when using a wireless terminal having an integrated interface, the number of codecs is limited, so the format of the provided multimedia content is inevitably limited.

In order to solve the above problems, the present invention enables the download of the player provided by the service company that wants to access the multimedia content from various service companies, and download the codec according to each multimedia content as needed An object of the present invention is to provide a downloadable multimedia service providing system and method in a wireless communication network capable of supporting multimedia services of various formats.
