摘要： PROBLEM TO BE SOLVED: To provide a multimedia processing system and method thereof.
SOLUTION: The system and method provide for synchronizing a first clock of a multimedia decoder of a first multimedia processing device to a second clock of a multimedia encoder of a second multimedia processing device, synchronizing a first timing reference of the multimedia decoder to a second timing reference of the multimedia encoder, receiving, at a network interface of the first multimedia processing device, an encoded data stream from a network interface of the second multimedia processing device, wherein the encoded data stream is encoded by the multimedia encoder based on the second clock and the second timing reference, and decoding the encoded data stream at the multimedia decoder based on the first clock and the first timing reference.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for dynamically adjusting the data rate of a wireless transport channel. SOLUTION: The method and the apparatus include processing that begins with one of a plurality of client modules, within a wireless multimedia system and monitors channel characteristics of a wireless transport channel. The monitoring operation is carried out, at or below a received packet rate (that is, a rate in receiving a packet) to determine variations in the channel characteristics (for instance, signal intensity, a signal-to-noise ratio, and the like) on a packet basis or on a packet group basis.

摘要： A method and apparatus for dynamic data rate adjustment of a wireless transport channel include processing that begins with one of a plurality of client modules within a wireless multimedia system monitors channel characteristics of a wireless transport channel. The monitoring is done at or below a received packet rate to determine variations in the channel characteristics on a packet-by-packet basis or on a group-of-packets by group-of packets basis. The processing continues when the client module determines whether the variations in the channel characteristics affect the data rate of data contained in the packets received via the wireless transport channel. When the variations in the channel characteristics affect the data rate, the client module provides data rate adjustment feedback to a multimedia server of the wireless multimedia system via the wireless transport channel. The processing continues when the multimedia server adjusts the data rate of the data contained in the packets being transported via the wireless transport channel in accordance with the data rate adjustment feedback.
