摘要： Techniques are provided for managing long-term reference frames (LTRFs) for two or more video sources. A first video source is selected from a plurality of video sources. The first video source is encoded to produce an encoded video stream, where a reference frame message identifies a recent video frame as long-term reference frame (LTRF) associated with the first video stream. The process is repeated for other video streams. The LTRF associated with the first video stream is used as a reference for temporal predictive coding upon receiving a signal that the first video source has been re-selected.
摘要翻译：提供了用于管理两个或多个视频源的长期参考帧（LTRF）的技术。从多个视频源中选择第一视频源。第一视频源被编码以产生编码视频流，其中参考帧消息将最近的视频帧标识为与第一视频流相关联的长期参考帧（LTRF）。对其他视频流重复该过程。与第一视频流相关联的LTRF在接收到已经重新选择第一视频源的信号时用作时间预测编码的参考。

摘要： An apparatus, a method, and a computer-readable medium having instructions encoded thereon that when executed cause a method to be carried out. The method includes dividing at least a portion of a picture of a video stream into parts of blocks, and processing the parts in parallel by a plurality of interconnected processors. The processing of a respective part by its respective processor includes determining block- features, e.g., block level temporal features and/or block level edge features. Each processor also performs coding functions on its respective part of the picture. The method also includes block-level processing using the block-level features to determine which blocks in the picture are likely to be that of a face, the block-level processing being at the granularity of at least a block.
摘要翻译：具有在其上编码的指令的装置，方法和计算机可读介质，所述指令在被执行时导致执行方法。该方法包括将视频流的图片的至少一部分划分成块的部分，并且通过多个互连的处理器并行处理这些部分。各个处理器对各部分的处理包括确定块特征，例如块级时间特征和/或块级边特征。每个处理器还在其相应的图片部分上执行编码功能。该方法还包括使用块级特征来确定图片中哪些块可能是面部块的处理的块级处理，块级处理处于至少一个块的粒度。
