摘要： Some embodiments provide an architecture (100) for establishing multi-particpant video conferences. This architecture (100) has a central distributor (125) that receives video images from two or more participants. From the received images, the central distributor (125) generates composite images that the central distributor (125) transmits back to the participants. Each composite image includes a set of sub-images, where each sub-image belongs to one participant. In some embodiments, the central distributor (125) saves network bandwidth by removing each particular participant's image from the composite image that the central distributor (125) sends to the particular participant. In some embodiments, images received from each participant are arranged in the composite in a non-interleaved manner. For instance, in some embodiments, the composite image includes at most one sub-image for each participant, and no two sub-images are interleaved.
摘要翻译：一些实施例提供了一种用于建立多参与视频会议的架构（100）。该架构（100）具有从两个或更多个参与者接收视频图像的中央分配器（125）。从所接收的图像中，中央分配器（125）生成中央分配器（125）传送回参与者的合成图像。每个合成图像包括一组子图像，其中每个子图像属于一个参与者。在一些实施例中，中央分配器（125）通过从中央分配器（125）向特定参与者发送的合成图像中移除每个特定参与者的图像来节省网络带宽。在一些实施例中，从每个参与者接收的图像以非交错方式排列在复合体中。例如，在一些实施例中，合成图像对于每个参与者至多包括一个子图像，并且没有两个子图像被交织。

摘要： Systems, apparatuses and methods whereby coded bitstreams are delivered to downstream end-user devices having various performance capabilities. A head-end encoder/video store generates a primary coded bitstream and metadata for delivery to an intermediate re-encoding system. The re-encoding system recodes the primary coded bitstream to generate secondary coded bitstreams based on coding parameters in the metadata. Each secondary coded bitstream is matched to a conformance point of a downstream end-user device. Coding parameters for each conformance point can be derived from the head-end encoder encoding original source video to generate the secondary coded bitstreams and extracting information from the coding process/results. The metadata can then can be communicated as part of the primary coded bitstream (e.g., as SEI) or can be communicated separately. As a result, the complexity of the secondary coded bitstream is appropriately scaled to match the capabilities of the downstream end-user device to which it is delivered.

摘要： Some embodiments provide a method for encoding a first set of pixels in a first image by reference to a second image in a video sequence (See Fig. 7, items 700 and 705). In a first search window within a second image, the method searches to identify a first particular portion in the second image that best matches the first set of pixels in the first image (See Fig. 7, item 715). In the first search window within the second image, the method identifies a first location corresponding to the first particular portion (See Fig. 7, item 710). In a second search window within the second image, the method then searches to identify a second particular portion in the second image that best matches the first set of pixels in the first image (See Fig. 7, item 720), where the second search window is defined about the first location (See Fig. 7, item 735).

摘要： Some embodiments of the invention provide a multi-pass encoding method that encodes several images (e.g., several frames of a video sequence). The method iteratively performs an encoding operation that encodes these images (Figure 1, 110). The encoding operation is based on a nominal quantization parameter, which the method uses to compute quantization parameters for the images (132). During several different iterations of the encoding operation, the method uses several different nominal quantization parameters (125). The method stops its iterations (140) when it reaches a terminating criterion (e.g., it identifies an acceptable encoding of the images).

摘要： A video coding/decoding system builds implied reference frames from a plurality of reference frames developed during coding. Coded data of reference pictures are decoded and stored in a reference picture cache. An implied reference frame may be derived from a plurality of reference frames and may be stored in the reference picture cache. Thereafter, coding of new input data may proceed using the implied reference frame as a source of prediction. The method may be used to identify visual elements such as background elements that may persist in video over a longer period that can be captured by the system under conventional reference frames assembly and eviction. Implied reference frames may be built at both an encoder and a decoder to serve as sources of prediction.

摘要： Embodiments of the present invention provide apparatuses and methods of coding video. The apparatuses and methods may further provide coding a source video sequence according to a block-based coding process, estimating processing capabilities of a target decoder, determining if the estimated processing capabilities are sufficient to perform deblocking filtering. If not sufficient, the apparatuses and methods may provide computing deblocking filter strengths for pixel blocks of the source video sequence to be used at decoding, and transmitting the deblocking filter strengths in a coded video data signal with the coded video data. Moreover, if not sufficient, the apparatuses and methods may provide changing coding parameters including, but not limited to, block sizes, transform sizes, and Qmatrix.
