METHOD FOR CONTROLLING MOVING PICTURE ENCODING USING CHANNEL INFORMATION OF WIRELESS NETWORKS
First Claim
1. An apparatus for transmitting/receiving data through a wireless communication network connected to the apparatus, the apparatus comprising:
- a channel state analyzing unit for analyzing a wireless channel environment;
an encoding controller for generating control information containing information about at least one of a quantization parameter, a skip or non-skip of frames indication, a frame type, and a use or non-use of an Error Resilient Tool (ERT) indication, in consideration of an analyzation result 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 data transmitting/receiving unit for transferring the encoded moving picture data through the wireless channel to an exterior.
