Equipment for transmitting and receiving MPEG data using radio LAN

Abstract

An apparatus for transmitting and receiving MPEG data using a wireless LAN, comprising: a first satellite broadcast receiver for decoding a satellite broadcast signal received from a satellite broadcast antenna and reproducing moving images and sound; a first data controller for receiving the satellite broadcast signal decoded in the first satellite broadcast receiver; the first radio data transceiver for selectively encoding the satellite broadcast signal input from the first data controller, and encoding the input satellite broadcast signal or The coded satellite broadcast signal is converted into a radio frequency signal and sent wirelessly; the second radio data transceiver is used to receive the satellite broadcast signal of the radio frequency signal received from the first radio data transceiver; the second data controller judges the first Whether the satellite broadcast signal received by the radio data transceiver has been coded and controls the transmission channel of the satellite broadcast signal according to the judgment result; the second satellite broadcast receiver decodes the coded satellite broadcast signal received from the second data controller or performing data processing on the satellite broadcasting signal input from the second data controller so as to reproduce moving images or sounds, wherein the first and second satellite broadcasting receivers perform data communication according to the DVB communication standard, and the first and second radio The data transceiver performs data communication according to the IEE802 communication standard.

Description

technical field [0001] The present invention relates to an apparatus for transmitting and receiving MPEG data using a wireless LAN, and more particularly, to an apparatus for transmitting and receiving MPEG data using a wireless LAN by effectively combining an apparatus having a different communication protocol such as a satellite broadcast receiver or a cable TV with a radio The transceiver is combined to be able to send and receive sound and image data wirelessly. Background technique [0002] Generally, satellite broadcasting is directly sent to the home. For this reason, the equatorial height of the communication satellite is as high as 36,000km, and different electronic equipment, relay equipment and solar panels are installed to act as a relay station. [0003] A satellite receiver that receives satellite broadcasts from a communication satellite includes a satellite dish that receives satellite signals, a set-top box that processes and outputs satellite signals receiv...

AI Technical Summary

Problems solved by technology

[0005] However, as described above, when satellite broadcasting is received from a set-top box connected to a satellite dish through a cable, there arises an inconvenience that a long cable is required to connect the satellite dish installed outdoors with the set-top box located indoors.
