The invention proposes a method for transmitting a data file containing a
content of known duration encoded at an encoding rate that is higher than
the channel transmission rate. The proposed method comprises the steps
of: downloading the data by using a transport protocol with rate control
(like TCP) during a first period of time, and streaming the data by using
a transport protocol without rate control (like UDP) during a second
period of time. The second period of time (streaming) is proportional to
the known duration of the content. Advantageously, the proportionality
factor is equal to one. Application transmission of audio/video via
Internet.
