Patent ID: 7729391

Claim:
A transmitting device comprising: a first buffer configured to temporarily store a first media data to be transmitted; a second buffer configured to temporarily store a second media data to be transmitted; a multiplexing means for multiplexing the first media data coming from said first buffer and the second media data coming from said second buffer to output a multiplexed data onto a single signal channel; a transmission buffer monitoring means for monitoring an amount of a first buffer data stored in said first buffer and, when the amount of the first buffer data exceeds a first threshold, instructing said second buffer to discard the second media data, such that only the first buffer data is received by the multiplexing means; and a transmission rate measuring means configured to measure a transmission channel rate when the amount of the first buffer data has exceeded the first threshold and when the amount of the first buffer data is less than or equal to a second threshold for a predetermined time, wherein said transmission buffer monitoring means instructs said second buffer to stop discarding the second media data when the transmission channel rate reaches a value higher than or equal to a predetermined transmission rate, such that data from the first buffer and the second buffer is received by the multiplexing means.
