Method and apparatus for transmitting and receiving in the wireless network controlling encoding and transmitting mechanism using video data s importance and network circumstance

摘要

A method and a system for transmitting and receiving data are provided to improve transmission efficiency by controlling a transmission mode and an encoding mode according to the transmission state of a wireless network and importance of video information. State information of a wireless network is received(S701). Data to be transmitted are classified based on the state information(S702). Transmission data to which information for recovering an error is added when the error is generated in the classified data are encoded. A decision factor for transmitting the transmission data to the wireless network is set according to the state information. The encoded transmission data is transmitted to the wireless network according to the set result(S730).
