Abstract: Data are received at a receiving device from a server, where the data are encoded into one of a plurality of different versions, each version having a different fidelity level. A data stream having a buffer with an initial maximum window size for buffering received data is requested from the server, wherein the data stream initially has a first fidelity level. The maximum window size is managed to prevent the current window size from falling below a threshold that might trigger an adjustment by the server in the fidelity level of the data stream sent by the server, unless and until the accumulation of data in the buffer due to a decrease in the present processing capabilities of the controller of the receiving device falls below a threshold of processing power necessary for processing the data stream at the higher fidelity level for more than a transitory period of time.

Abstract: A method of dynamically buffering content for providing a streaming service is provided. The method includes estimating a maximum amount of decrease in a network speed based on a result of measuring a network, and determining an amount of data to be buffered so that additional buffering, after playback of content is started, does not cause playback interruption, based on a maximum amount of decrease in the network speed, a total size of the content, a speed of playing the content, and a speed of receiving the content.
