Method for controlling moving picture encoding using channel information of wireless networks

A method for encoding and transmitting moving picture data by a data transmitting/receiving apparatus connected to a wireless communication network, the method comprising the steps of:

• analyzing a channel environment by identifying a wireless channel state;
• generating control information containing information regarding a quantization parameter, a skip or non-skip of frame indication, a frame type, and use or non-use of an ERT indication, in consideration of an analyzation result of the wireless channel environment;
• encoding moving picture data in reflection of the control information;
• and
• transferring the encoded moving picture data through the wireless channel.

A data transmitting/receiving system comprising:

• a wireless communication network;
• a data transmitting apparatus connected to the wireless communication network, wherein the data transmitting apparatus includes:
• a channel state analyzing unit for analyzing a wireless channel environment of a transmitting side,
• an encoding controller for generating control information containing information about at least one of quantization parameters, skip or non-skip of frames indications, frame type indications, and use or non-use of an ERT indication, in consideration of results of the analysis of the wireless channel environment received from the channel state analyzing unit;
• a moving picture encoding unit for encoding incoming moving picture data based on the control information received from the encoding controller, and
• a communication module of the transmitting side for transferring the encoded moving picture data to an exterior through a wireless channel;
• a data receiving apparatus connected to the wireless communication network, wherein the data receiving apparatus includes:
• a communication module of a receiving side for receiving data transferred from the wireless communication network, and
• a decoding unit for decoding the moving picture data received through the communication module of the receiving side.
