Embodiment Construction

[0030] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0031] According to the present invention, a TV broadcast signal is spread with a predetermined spreading code (or Walsh code) and transmitted using a separately prepared broadcasting frequency. Then, an MS receives the TV broadcast signal without call establishment. Here, the extension code is a Walsh code, which is used for the SCH of 153.6Kbps in IMT-2000. Channels that provide TV broadcasts are referred to as Broadcast Channels ("BCH").

[0032] figure 2 is a functional block diagram of the entire mobile communication system for providing broadcast services according to the present invention. refer to figure 2 , the TV broadcasting system 201 transmits video and audio signals to user terminal...

Abstract

An apparatus and method for providing broadcasting service in a mobile communication system. A format converter transcodes video data received from video resources to a format suitable for the mobile communication system. A base station spreads the transcoded video data with a predetermined dedicated spreading code and broadcasts the spread video signal. A mobile station receives and despreads the broadcasting signal from the base station with the spreading code.

Description

[0001] This application claims priority to Application Serial No. 2001-47416, filed on August 7, 2001 at the Korean Intellectual Property Office, entitled "Apparatus and Method for Providing Television Broadcasting Services in a Mobile Communication System," the contents of which Incorporated here for reference. technical field [0002] The present invention generally relates to an apparatus and method for providing broadcast services in a mobile communication system, and more particularly, to an apparatus and method for providing television ("TV") broadcast services in a mobile communication system. Background technique [0003] Communication technology is developing so rapidly that it is expected that in the future there will be no distinction between wired and wireless communications worldwide. In particular, future communication systems such as IMT-2000 are planned to provide users with various information including audio and video information in real time and on a large...
