1 is a block diagram illustrating an embodiment of a configuration of a signal transmission / reception system, and the signal transmission / reception system may include a transmission device 100 and a reception device 200.

Referring to FIG. 1, the transmission apparatus 100 receives a media signal including an image from an airwave, a cable, or an external device, and converts the received media signal into data in a wireless transmission format for wireless transmission. do.

The receiving device 200 receives and processes data wirelessly transmitted from the transmitting device 100, and for this purpose, at least one wireless communication standard for wirelessly transmitting and receiving data between the transmitting device 100 and the receiving device 200 is provided. It may be set in advance.

Meanwhile, the transmitting apparatus 100 may include an HDMI or a high-definition multimedia interface (HDMI) terminal, a universal serial bus (USB) terminal, a component terminal, an external input terminal, an RGB terminal, and an antenna to which an external device is connected. Various input terminals such as a cable terminal may be provided to receive a media signal using the input terminal.

The transmitting device 100 may be a set-top box (STB) that receives a media signal using a wired or wireless network, converts the received media signal and wirelessly transmits the received media signal to the receiving device 200.

However, the transmitting apparatus 100 according to the present invention is not limited to the set top box STB, and may include any kind of apparatus capable of receiving a media signal transmitted from the outside and wirelessly transmitting it to the receiving apparatus 200. .

For example, the transmitting device 100 according to the present invention may be provided in a portable terminal such as a computer or a mobile phone.

In addition, the reception apparatus 200 may receive and process data transmitted wirelessly from the transmission apparatus 100 and then transmit the data to an external device that outputs an image or audio included in a media signal.

For example, the reception apparatus 200 may convert an image signal wirelessly transmitted from the transmission apparatus 100 into a form that can be displayed on a display apparatus (not shown) and then output the converted image signal. More specifically, when the video signal wirelessly transmitted from the transmitting device 100 is encoded by a coding scheme such as MPEG, the receiving device 200 decodes the received video signal. And output to a display device (not shown).

According to an embodiment of the present invention, the transmitting device 100 and the receiving device 200 may be connected to various wireless communication standards, for example, wireless HD (WiHD), wireless home digital interface (WHDi), or wireless LAN (WiFi).

In addition, the WiFi may transmit and receive data at a transmission rate of about 54 Mbp using a frequency band of 2.4 GHz. Since the WiFi uses a low frequency band of 2.4 GHz, the transmission and reception distance is about 50 to 200 m, and the transmission and reception quality may be almost unaffected by peripheral obstacles in the installation space. On the other hand, according to a low transmission rate of about 54Mbp, if you want to transmit 1080p (1920 × 1080) HD video data using the WiFi, the transmitting device 100 must compress and transmit the HD video data, accordingly An image quality deterioration may occur in an image signal received by the reception apparatus 200.
