Patent ID: 7697553

Claim:
A method of adjusting a flow rate of data transmitted from a first packet switched H.323 or SIP configured video conference terminal and received in a H.323/H.320 video conference gateway, the method comprising: storing the received data temporarily in one or more buffers in the H.323/H.320 video conference gateway before being captured for further processing; after each data capturing from said one or more buffers, comparing, at the H.323/H.320 video conference gateway, a fill level of the one or more buffers with a predefined level, wherein said predefined level is equal to a maximum amount of data in a H.320 frame, into which data captured from the one or more buffers is inserted, if said fill level is lower than said predefined level, then resetting a counter, if said fill level is greater than said predefined level, then incrementing, at the H.323/H.320 video conference gateway, said counter, and comparing, at the H.323/H.320 video conference gateway, said counter with a predefined counter limit, if said counter is greater than said predefined counter limit, then resetting, at the H.323/H.320 video conference gateway, said counter, and decreasing the flow rate of the transmitted data by transmitting, at the H.323/H.320 video conference gateway, a flow control message to the first packet switched terminal instructing the first packet switched terminal to decrease the flow rate according to a flow rate value included in said flow control message.
