Patent

CA 2280662

A method and system for managing scalable compression of multicast media over an Internet protocol, between a media server and a client. The method includes the steps of determining the client access bandwidth statistics, determining a data buffer status of the client, generating a quantization mask in response to the buffer status, applying the quantization mask to an array of transformed frame data for each frame in a sequence, or group of frames in three-dimensional case, to produce quantized data, performing arithmetic coding on the quantized data to produce a bit stream; and transmitting the bitstream to the client.
