Embodiment Construction

[0026] A digital broadcasting apparatus according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] figure 2 is a view of a digital broadcast receiving apparatus according to an embodiment of the present invention.

[0028] refer to figure 2 , the set-top box 100 is connected to the head end 200 by a cable, and includes an in-band signal receiving unit 110, an out-of-band signal receiving unit 120, an out-of-band signal transmission unit 130, an analog-to-digital conversion (ADC) unit 141, a digital-to-analog conversion (DAC) unit 142 and the control unit 150.

[0029] The set-top box 100 receives an in-band signal through a cable (for example, a coaxial cable) connected to the headend 200, demodulates the received signal, and transmits the demodulated signal to a display device such as a television. Here, the headend 200 transmits in-band signals such as images and sounds carrying a transport stream (e...

Abstract

Provided are a digital broadcast receiving device and method. The digital broadcast receiving device includes: an out-of-band signal receiving unit configured to receive an out-of-band signal through a cable; an out-of-band signal transmission unit configured to transmit the out-of-band signal through the cable; and a control unit configured to A gain of the out-of-band signal of the out-of-band signal transmission unit is controlled according to a level change of the out-of-band signal received by the out-of-band signal receiving unit.

Description

technical field [0001] The present invention relates to a digital broadcast receiving device and a receiving method thereof. Background technique [0002] As broadcasting media has been digitized, terrestrial and satellite digital multimedia broadcasting services are provided. Recently, as cable broadcasting uses a digital system, digital multimedia broadcasting services are more efficiently provided. [0003] With the wide spread of coded media, the digitization of broadcast signals will accelerate the convergence of communications, computers, and broadcasting, realize the internationalization and multi-channel of a single multi-functional media, and provide multiple data services. [0004] Cable broadcast networks are designed to deliver high-quality television signals received using highly sensitive antennas to every household's television. The service of a cable broadcast network begins with solving the problem of coverage area. In addition, the cable broadcasting net...
