摘要： The disclosed subject matter describes a new pattern description that can be part of an SEI message or a parameter set, and can be used to describe a temporal picture coding structure and associated bitrates and frame rates. The knowledge of the coding structure can benefit transraters, bitstream extractors, and digital video recorders. Decoders can utilize the coding structure information for example, to decode pictures in parallel, using multiple threads/cores.

摘要： Systems and methods for conducting a multi-endpoint video signal conference are provided. Conferencing endpoints are linked by pairs of a reliable and a less reliable communication channel. Conference video signals are scaleable coded in base layer and enhancement layers format. Video signal base layers, which correspond to a minimum picture quality, are communicated over reliable channels. The video signal enhancements layers may be communicated over the less reliable channels. A conference server mediates the switching of video layer information from transmitting endpoints to receiving endpoints without any intermediate coding or re-coding operations. The video conference can be integrated with an audio conference using either scalable coded audio signals or non-scaleable coded audio signals.

摘要： Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

摘要： The present invention provides bit rate control techniques for a hybrid block based motion compensated predictive video encoder (e.g., H.264, as well as other video coding algorithms and standards). The techniques aim to reduce the picture-to-picture bit rate fluctuations within a prediction structure or over a short time interval that can lead to undesirable additional delay on links without over-provisioned capacity. In one embodiment of the present invention, the end to end delay is estimated. The end to end delay is used to determine limits on the modulation of the target coded picture size, with the goal of trading an acceptable amount of additional delay for a better coding efficiency.

摘要： Techniques for transmission and preparation for display of real-time audio-visual content of a plurality of TV programs over electronic communications network channels and display of the audio-visual signals as a part of a TV Electronic Programming Guide (EPG) are disclosed herein. In particular, the use of video coded using a layered codec, and stored in a layered format, allows a properly configured system to present to an end user a live preview of multiple TV channels, along with EPG information (e.g., the channel, time, title and genre of video content, a list of programs scheduled in the future, as well as the ability to, for example, set parental controls, order pay-per-view programs, to search for programs based on theme or category, and to set recordings for the future when combined with a recording system), on his/her TV screen, without taking significantly more resources (e.g., in terms of bandwidth, system complexity) than the traditional digital TV transmission.

摘要： The disclosed subject matter provides techniques for inter-layer prediction using difference mode or pixel mode. In difference mode, inter-layer prediction is used to predict at least one sample of an enhancement layer from at least one (upsampled) sample of a reconstructed base layer picture. In pixel mode, no reconstructed base layer samples are used for reconstruction of the enhancement layer sample, A flag that can be part of a coding unit header in the enhancement layer can be used to distinguish between pixel mode and difference mode.
