IPTV BROADCAST SYSTEM AND CHANNEL SETTING METHOD USING MULTI-CHANNEL STREAMING SERVER

摘要

Provided are an IPTV broadcast system and a channel setting method using a multi-channel streaming server. The system includes a set-top box (STB), a program guide database (DB), a transmission block storing unit, a customer management server, and the multi-channel streaming server. The STB performs a connection setting procedure for generating predetermined transmission control protocol (TCP) connection with the multi-channel streaming server when a user selects a channel and initially accesses an IPTV broadcast server system, and then requesting contents corresponding to information of the selected channel to reproduce received streaming data while buffering the same in a storage. The program guide DB stores transmission block information to be transmitted according to a time for each channel. The transmission block storing unit stores a transmission block of respective contents. The customer management server stores customer information and authentication information and processes authentication when authentication is requested. The multi-channel streaming server communicates with the customer management server to authenticate a user according to a predetermined authentication procedure when connection setting is requested by the STB, sets connection when the authentication is successful, searches for the program guide database according to the channel information to find out information regarding a transmission block corresponding to a channel number and a time band requested by the STB, fetches the transmission block from the transmission block storing unit, and transmits the transmission block to the STB.
