Problems solved by technology

Therefore, existing analog TVs that cannot receive and process digital TV signals experience difficulties when used in a digital TV broadcast environment
[0003] Alternatively, an existing analog TV can continue to be used with the help of an additional digitizer that converts the digital TV signal into an analog TV signal, which can result in an expense for the digitizer

Embodiment Construction

[0027] Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings so as to be more easily understood by those of ordinary skill in the art.

[0028] figure 1 A broadcast transmitting / receiving device according to an exemplary embodiment of the inventive concept is shown. Such as figure 1 As shown, the broadcast transmitting / receiving apparatus 1 may be implemented as a digital TV or a digital TV set-top box capable of receiving and processing digital TV signals. The broadcast transmitting / receiving apparatus 1 receives digital TV signals, and then converts the received digital TV signals into analog TV signals. The broadcast transmitting / receiving device 1 transmits an analog TV signal in the form of radio waves. The analog TV 2 receives and processes analog TV signals in the form of radio waves. The analog TV 2 receives and processes an analog TV signal transmitted from the broadcast transmission / reception apparatus 1 and ou...

Abstract

A broadcasting transmitting / receiving apparatus and a control method thereof are disclosed. The broadcasting transmitting / receiving apparatus includes: a signal receiving unit which receives a digital TV signal; a first signal processing unit which acquires video and / or audio from the received digital TV signal; a second signal processing unit which generates an analog TV signal which includes the acquired video and / or audio; an antenna unit which transmits the generated analog TV signal; and a controller which controls the first and second signal processing units to transmit the analog TV signal which corresponds to the digital TV signal selected from among a plurality of channels. With this configuration, it is possible for a user to view a digital TV broadcasting on an existing analog TV at minimal additional cost.

Description

technical field [0001] Methods and devices consistent with the exemplary embodiments relate to a broadcast transmission / reception device that receives a broadcast signal (eg, TV (television) signal) and outputs video / audio. Background technique [0002] With the recent activation of digital broadcasting, the current trend is to shift from existing analog TV broadcasting to digital TV broadcasting. Accordingly, existing analog TVs that cannot receive and process digital TV signals experience difficulties when used in a digital TV broadcasting environment. [0003] Alternatively, an existing analog TV can be continued with the aid of an additional digitizer that converts the digital TV signal into an analog TV signal, which can incur costs for the digitizer. Contents of the invention [0004] Accordingly, one or more exemplary embodiments provide a broadcast transmission / reception apparatus that allows a user to watch a digital TV broadcast using an existing analog TV at a ...
