Embodiment Construction

[0063] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0064] First, if figure 1 As shown, the wireless communication system of the present invention is composed of an image transmission unit (sending device, communication device) 20 that receives image data and transmits it in SS wireless mode, and a display unit ( A receiving device, a communication device) 30, and a remote control device (selection means, remote control device) (not shown).

[0065] The image transmission unit 20 is preferably a transmission unit that receives CATV signals or television waves, for example, and uses a carrier wave with a frequency band of several GHz or more to transmit a large-capacity image signal to the display unit 30 . For this purpose, a communication method such as a so-called SS (Spread Spectrum) wireless method such as a direct spread (DS) method or a frequency hopping (FH) method is preferable.

[0066] The display unit 30 is ...

Abstract

A worker selects at least one antenna for a video transmission unit (20) and a display unit (30) by means of a remote control (80). A selection signal sent out from the remote control (80) is received by light-receiving means (69, 78) and transmitted to microcomputers (67, 75). The microcomputers (67, 75) allow the selected and specified antennas to function, among the antennas (26, 27) of radio transmitting / receiving means (65) and the antennas (41, 42, 43) of radio transmitting / receiving means (79).

Description

technical field [0001] The present invention relates to a wireless communication system for transmitting and displaying image data by wireless communication such as a wireless LAN, and more particularly to a wireless communication system, a transmitting device, a receiving device, a communication device, a data transmitting method, and a data receiving device capable of checking the communication performance of a plurality of antennas. A method, a program, and a computer-readable recording medium recording the program. Background technique [0002] In recent years, portable mobile wireless communication devices such as liquid crystal televisions and CRT televisions have been proposed, and methods for transmitting and receiving image signals using SS (Spread Spectrum) wireless methods based on IEEE802.11 or IEEE802.11B have been proposed. device. In particular, this wireless communication device has proposed not only the above-mentioned wireless method, but also a next-gener...
