Streaming - Sony Ericsson D750i White Paper

Streaming

Streaming media is a method of making audio,
video clips and other multimedia available in real-
time.
The term streaming refers to the technique it is
based on. Previously an entire file had to be down-
loaded before it could be played, whereas the use
of streaming means the end user can almost imme-
diately begin to watch or listen to the content of a
requested file. The data in the file is broken down
into small packets that are sent in a continuous
flow, a stream, to the end user. It is then possible to
begin viewing the file while the rest of the packets
are transferred.
Applications
The applications which can be built on top of the
streaming services can be classified into on
demand, and live information delivery applications.
Examples of the first category are music and video
clips, news on demand as well as on demand
instruction material. Live delivery of radio and tele-
vision are examples of live information delivery. The
following video and music codec is supported:
• MPEG-4 Simple Visual Profile Level 0
• H.263 Profile 0 Level 10
• AAC
• AMR
• MP4
• 3GP
Examples of usage
