1. A method for receiving an Hyper Text Transport Protocol (HTTP) adaptive streaming video from a server, said method comprising at a client, operatively connected to said server:
upon receiving a chunk of said video, determining a current rate of transmission for transmissions from said server to said client; obtaining statistical information pertaining to an expected future rate of transmission, in function of at least said current rate of transmission; deriving a target rate of transmission from said statistical information; and requesting a subsequent chunk of said video in accordance with said target rate of transmissions; the method further comprising updating said statistical information with said determined current rate of transmission, wherein said statistical information is obtained from and updated at a network node that is separate from said client, said network node being configured to store statistical information from a plurality of clients; wherein said statistical information comprises a histogram, and wherein said deriving comprises calculating a predetermined quantile from said histogram; wherein said quantile is one of a 5-percentile, a 1-percentile, and a 0.1-percentile; and wherein said rate of transmission information is stored at said network node in association with auxiliary information, such as an associated network type, a time of day, or a day of week.
