Embodiment Construction

[0036] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.

[0037] figure 1 is a view showing a typical broadcast receiving system.

[0038] see figure 1 , the broadcast receiving system 1 includes a display device 2 and a set-top box 10 . The display device 2 and the set-top box 10 are connected by a cable 3 , and an electric signal of the set-top box (STB) 10 can be sent to the display device 2 .

[0039] Although not shown, set-top box 10 may include some or all of the following: a signal receiver, a signal processor, memory, a controller, and a signal output.

[0040] The signal receiver may receive broadcasting signals of groundwave broadcasting, cable television broadcasting, and satellite broadcasting. Here, the broadcast signal may be received based on at least one of an analog mode and a digital mode.

[0041] A broadcast signal received by the signal receiver for a specific channel may be transmitted to the signal p...

Abstract

A set-top box with a heat dissipation device is provided to improve heat dissipation efficiency. The set-top box includes a main body configured to form an exterior, a circuit board provided inside the main body, and a heat dissipation device provided to cool heat generated from the circuit board. The heat dissipation device includes a heat pipe provided to be in contact with at least one surface of the circuit board.

Description

technical field [0001] Embodiments relate to a set top box having a heat dissipation device to improve heat dissipation efficiency. Background technique [0002] In general, a Set Top Box (STB) is a signal conversion device that receives a broadcast signal transmitted from a terrestrial cable or satellite so that the signal can be displayed by a display device such as a television (TV). The STB receives a broadcast signal using a tuner, converts the received signal into video, audio, text, etc. using a decoder, and transmits the converted result to a TV. When a program that the user wants to watch is selected, data of the selected program is transmitted to the STB through, for example, a cable, and the user can watch the desired program through a display device connected to the STB. [0003] With the advent of digital broadcasting services, the number of broadcast channels sent from terrestrial cable or satellite exploded. In order to receive broadcasts of a large number o...
