ABSTRACT:
Audio-visual data is provided to a network-connected terminal. First audio-visual data containing first information encoded at a first data rate and second audio-visual data containing first information encoded at a second data rate that is more than the first data rate are received. The first audio-visual data is provided to the network-connected terminal. A condition is identified to the effect that the amount of data being sent to the terminal is less than the available bandwidth. The difference between the data rates of the first and second audio-visual data is calculated, additional data packets are sent to the terminal to determine whether the available bandwidth is large enough to provide the first audio-visual data to the terminal; and if it is determined that the available bandwidth is large enough, provision of the first audio-visual data to the terminal is stopped and the second audio-visual data is provided instead.
