Description

Description TUNER MODULE
Technical Field
[1] Embodiments relate to a tuner module.
Background Art
[2] A tuner module can be applied to a digital broadcasting receiver such as a digital television (DTV) or a set-top box (STB). The tuner module can be classified into a single tuner module selecting only one channel, and a dual tuner module selecting two channels.
[3] A digital broadcasting receiver to which the dual tuner module is applied can perform a function of selecting two channels simultaneously to view one of the channels and store contents provided through the other in a storage medium. Also, a digital broadcasting receiver having a picture-in-picture (PIP) function can display one channel through a main screen and display the other channel through a sub-screen.
[4] Generally, the dual tuner module comprises a main tuner and a sub-tuner to perform a PIP function. At this point, the main tuner and the sub-tuner are disposed inside separate chassis, respectively. The sub-tuner is realized to receive antenna-reception signals from the main tuner through separate cable connection.
[5] However, since signals are distributed and supplied between the main tuner and the sub-tuner using a separate cable, separate connectors required for the cable connection should be provided to the main tuner and the sub-tuner, respectively. Also, an external noise may be introduced through the cable. Disclosure of Invention Technical Problem
