    Abstract: The present invention provides a method (900) and device (100) in multimedia communication systems for efficiently segmenting information bitstreams from multiple media sources into variable length packets, and multiplexing and sending the packets to a shared communication link with low delay and low overhead. The packet segmentation and multiplexing are performed dynamically based on fullness of a set of information buffers that contain the information bitstreams to be transmitted, and delay-sensitivity of each information bitstream. The multi-discipline queuing scheme has been developed in this invention to control the dynamic packet segmenting and multiplexing process.

    Abstract: The method (1100) and device (200, 900, 1400) of the present invention provides a mechanism to apply smoothing delay to video packets transmitted through a packet-switched network. Since the method and device using this invention perform a smoothing delay at video frame level, instead of packet level, smoothing delay can be minimized and at the same time the video decoder overflow can still be prevented. The present invention reduces system complexity by eliminating the need to recover the time stamp for each packet. Furthermore, the present invention does not require the prior knowledge of the worst network delay Δ. Thus, the present invention provides for a minimized jitter smoothing delay with concurrent minimized implementation complexity.

    Abstract translation: 本发明的方法(1100)和装置(200,900,1400)提供了一种对通过分组交换网络发送的视频分组进行平滑延迟的机制。 由于使用本发明的方法和装置在视频帧级执行平滑延迟,而不是分组级,可以使平滑延迟最小化,并且同时可以防止视频解码器溢出。 本发明通过消除恢复每个分组的时间戳的需要来降低系统复杂度。 此外,本发明不需要最差网络延迟DELTA的现有知识。 因此,本发明提供了最小的抖动平滑延迟,同时最小化实施复杂度。

    Abstract: A priority assignment method (100) and device (300) are set forth for assigning a priority to a selected speech frame coded by a linear predictor coder based on at least two of: an energy of the speech frame, a log spectral distance between selected consecutive frames, and a pitch predictor coefficient for the selected speech frame. The invention protects against loss of perceptually important and hard-to-reconstruct speech frames.
