The present invention relates to converting media bitstreams across different networks in a media gateway without any algorithmic delay, and reduces the computation load within the transmission in the situation where the bandwidth of the outgoing network varies dynamically. A first embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Media Stream Unit Conversion module which is a light weight Simple Pass-Through operation. A second embodiment of the present invention provides an apparatus and a method for a Reduced-Algorithmic-Delay Video Rate Conversion. An alternative embodiment provides an apparatus and a method for a Smart Pass-Through Operation which involves switching between the Simple Pass-Through and the Rate Converter. The methods and apparatuses provided by the first and second embodiment can be used as a stand alone system, or as part of the module of the alternative embodiment.

Method and apparatus for compressed video bitstream conversion with reduced-algorithmic-delay

A method of transmitting media to a client by an infrastructure device in a packet-switched network includes receiving a media stream at the infrastructure device. The method also includes determining an adaptation strategy according to at least one of one or more pieces of network information associated with the packet-switched network, one or more pieces of client information associated with the client, or one or more policies. The method further includes adapting the media stream according to the adaptation strategy to produce an output media stream.

A method of transmitting a coded media frame comprises determining a plurality of media frame sizes including a media frame size, transmitting an element comprising the plurality of media frame sizes, and thereafter receiving an input media frame. The method also includes processing the input media frame according to the media frame size to provide a coded media frame, and transmitting the coded media frame.

A method of removing a motion vector from a group of motion vectors used in an encoding process includes providing a list of motion vectors, selecting an initial motion vector from the list of motion vectors, and providing an intermediate motion vector using a motion vector refinement process. The motion vector refinement process uses, in part, the initial motion vector. The method also includes forming a region defined by one or more parameters associated with the initial motion vector and one or more parameters associated with the intermediate motion vector, selecting an additional motion vector from the list of motion vectors, determining that the additional motion vector points into the region, and modifying a state of the additional motion vector.
