Abstract: The present invention provides methods and apparatus for improving video quality in statistical multiplexing. For each encoding channel in a statistical multiplexer, a respective bit rate need parameter is calculated for encoding of a current frame in that encoding channel. A video buffering verifier level (VBV_Fullness) available to each encoding channel is also calculated. It is then determined whether the VBV_Fullness available to each encoding channel is sufficient for encoding the current frame of that encoding channel based on an initial complexity estimate for that current frame. In the event that the VBV_Fullness is determined to be sufficient, the current frame is encoded using the need parameter. In the event that the VBV_Fullness is determined to be insufficient, the need parameter is scaled by an adaptive panic multiplier and the current frame is encoded using the scaled need parameter.

Abstract: Methods and apparatus for statistical multiplexing in a dual pass encoding scheme are provided. A first pass encoder encodes alternate slices of anchor frames as I-slices and P-slices respectively in order to generate statistics for both I and P frame encoding for the same anchor frame. A second pass encoder determines the encoding complexity estimates for a plurality of frames in a look-ahead pipeline and sums the encoding complexity estimates of selective frames in the look-ahead pipeline to determine the initial need parameter for a current frame to be encoded. The second pass encoder computes a need parameter for encoding the current frame based on the initial need parameter. The need parameter is used by a statmux processor to determine the encoding bit rate for second pass encoding of the current frame.

Abstract: Methods, systems, and computer program products for establishing transcoding free connections between UMA and UMTS call legs are disclosed. According to one method, a media gateway determines whether codec configurations used by UMA and UMTS legs of a call are compatible. In response to determining that the configurations are compatible, media gateway determines whether rate control is necessary to establish a transcoding free connection. In response to determining that rate control is necessary, the media gateway issues rate control requests on the UMA and UMTS legs as appropriate. The media gateway determines whether the rate control requests are successful. In response to determining that the requests are successful, the media gateway establishes a transcoding free connection between the UMA and the UMTS legs of the call.

Abstract: Methods and systems for providing lawful intercept of a media stream in a media gateway include establishing a call context between a first termination and a second termination and establishing a tap context with at least one tap termination, which refer to the first termination. The call context defines a call media stream between the first and second terminations associated with a call between first and second end users. The tap context defines at least one tap media stream from the first termination to the at least one tap termination. The tap media stream is a one-way media stream that carries either the mouth portion of the call media stream, the ear portion of the media stream, or a combination of the mouth and ear portions of the media stream from the first termination to the at least one tap termination. Multiple tap contexts can be created to support the lawful intercept of the call by multiple law enforcement agencies.

Abstract: The present invention discloses a system and method for adaptive adjustment of bit budget that favors the allocation of bits to intra coding frames (I frames). Namely, an encoder is able to dynamically adjust the bit budget for each picture type in an image sequence, thereby effecting proper usage of the available transmission bandwidth and improving the picture quality. In one embodiment, the present invention will allocate more encoding bandwidth to a current Intra coding frame when the average quantization level of inter coding frames (e.g., P and B frames) of a previous group of pictures is relatively high.

Abstract: Methods and systems for controlling media stream handover in a media gateway includes establishing a call context between a first termination and a second termination in a media gateway. The first and second terminations are capable of bi-directional media stream communications associated with a call between first and second end users. In response to a handover event affecting the first termination, a third termination is added to the context. The third termination is initially capable of receive-only communications. The context is then modified such that the third termination becomes capable of bi-directional media stream communications and the first termination becomes capable of receive-only communications. The first termination is then removed from the context. The media stream handover may be performed using extensions to a media gateway control protocol and without using a conference bridge.
