Multimedia streaming technologies consist of a portfolio of algorithms and techniques that allow users to share multimedia content seamlessly within a range of different terminals (set-top boxes, PCs, DVD players/recorders, mobile phones, and other on-the-go products), connected through wired and wireless links. The implementation of streaming technologies in consumer devices will allow consumers to seamlessly access preferred movie, music, or other data wherever, whenever they want it without regard to where the content is physically stored or created. / @, Q: o$ C# Z

The techniques allow the enhancement of technologies such as multimedia coding/playback with robust and adaptive delivery/rendering algorithms. These algorithms optimize multimedia transmission and sharing through Internet Protocol and packet-based communication, with the final aim to offer the best experience to the user. * Y0 U# \6 b; f R6 v & o4 U d/ _& Z4 Z( \4 r' SBecause of the complexity of the technologies to be interconnected, multimedia streaming poses a number of technical challenges. Among the complexities are the particular nature of still images, video and audio signals, the best-effort nature of the Internet Protocol, the lossy nature of most wireless links, and the need to connect devices already present in the field. 7 d% C1 v L2 r!
