Embodiment Construction

[0026] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. In addition, terms used in the present invention are mainly selected from currently available global and generic terms. However, the applicant arbitrarily uses the most appropriate terms to keep up with the emergence of new technologies. And, the meanings of arbitrarily used terms are clearly explained in the corresponding descriptions. Therefore, in the process of understanding the present invention, the present invention will be understood not by simple term names but by the meaning of terms.

[0027] First of all, the terms used in the description of the present invention are preferentially explained as follows. A cable broadcasting station that transmits cable broadcasting is called a headend (eg, SO ...

Abstract

A digital cable broadcast system includes a broadcast transmitter and a digital cable TV receiver. The TV receiver includes a POD module which receives a generic feature control message from the broadcast transmitter. The generic feature control message includes cable band information identifying a cable band selected by the broadcast transmitter. The POD module generates application protocol data including the cable band information. The TV receiver further includes a host device which parses the cable band information from the application protocol data and tunes to a channel based on the cable band identified by the parsed band information in order to receive a cable broadcast signal from the transmitter.

Description

technical field [0001] The present invention relates to a cable broadcasting transmitting / receiving system for transmitting and receiving cable broadcasting, and more particularly to a digital cable broadcasting system, television receiver and method in which a transmitting end transmits cable band information and a receiving end receives the cable band information for processing. Background technique [0002] Typically, each channel frequency of a cable broadcast can be transmitted on a fixed frequency band or one of a plurality of frequency bands. For example, in North American metropolitan cable broadcasting, there are three cable frequency bands, that is, an STD (Standard Frequency) frequency band, an HRC (Harmonic Related Carrier) frequency band, and an IRC (Incremental Related Carrier) frequency band. Each cable broadcast station selects one of the three cable frequency bands to serve one cable broadcast. [0003] The STD band is a frequency allocated by the FCC (Fede...
