Embodiment Construction

[0021] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings. In the following description of the present invention, a detailed description of well-known functions and constructions incorporated herein that may make the subject matter of the present invention unclear will be omitted.

[0022] An Internet Protocol TV (IPTV) system is an example of a system for providing content using the Internet, which can be roughly classified into a server, a network, and a receiver.

[0023] The server of the IPTV system includes several servers responsible for various functions, such as a service discovery & selection (SD&S) server, a streaming server, a broadband content guide (BCG) server, a customer information server, and a payment information server. Among these servers, a streaming server transmits video data encoded in MPEG2 (Moving Picture Experts Group) or MPEG4 format over a network using Real-time Tra...

Abstract

A broadcast transmitting apparatus, method of transmitting broadcast data, broadcast receiver, and method of receiving broadcast data are disclosed. If data of a contents guide is updated, updated information of the contents guide is transmitted to the broadcast receiver. The broadcast receiver receives the updated information and can determine whether the contents guide data has been updated, based on the updated information. Therefore, the updated contents guide data can be requested and received as needed, thus reducing burdens of a network and receiver. Further, the receiver can maintain the latest information about contents, so as to increase reliability of information.

Description

technical field [0001] The present invention relates to a broadcast transmitting device, a method of transmitting broadcast data, a broadcast receiver and a method of receiving broadcast data. Background technique [0002] Existing television (TV) services are provided in a manner of transmitting content generated by a broadcaster through a radio wave transmission medium such as terrestrial wave, cable, or satellite, and viewers are provided by being able to receive content transmitted via various transmission mediums. Content TV receivers to view these transmitted content. However, with the development and commercialization of digital TV technology based on digital broadcasting, different from the existing analog broadcasting, in addition to the existing transmission medium, it is also possible to use the Internet connected to each home to provide viewers with Various contents such as live broadcasts, content on demand (CoD), games and news etc. Internet Protocol TV (IPTV...
