摘要： Methods and apparatus for efficient encoding multimedia data, such as live video streams are disclosed. The multimedia data is pre-encoded into multiple layers and characteristics of the pre-encoded data are determined. Based at least in part on the determined characteristics, the multimedia data is encoded into multiple layers.

摘要： The invention is directed to a method and apparatus for providing temporal scaling frames for use in digital multimedia. The method involves using a removable unidirectional predicted temporal scaling frame communication along with intra-coded frames and/or inter-coded frames. The method involves the ability to selectively remove the temporal scaling frame(s) from being transmitted or decoded in order to satisfy, for example, power limits, data rate limits, computational limits or channel conditions. Examples presented include encoders, transcoders and decoders where the decision to drop the removable temporal scaling frames could be made.
摘要翻译：本发明涉及用于提供用于数字多媒体的时间缩放帧的方法和装置。该方法涉及使用可移动单向预测的时间缩放帧通信以及帧内编码帧和/或帧间编码帧。该方法涉及到能够选择性地去除时间缩放帧以被传送或解码以满足例如功率限制，数据速率限制，计算限制或信道条件。提出的示例包括编码器，代码转换器和解码器，其中可以进行放弃可移动时间缩放框架的决定。

摘要： A method, system, computer program product, and computer system for processing video frames. Frames A and B of a pair of successive video frames each comprise blocks of pixels. Frame A is earlier in time than frame B. A connection state of each pixel in frame B relative to the pixels of frame A is determined. The connection state is a connected state or an unconnected state. Each block in frame B is classified as either unconnected or uni-connected. Uni-connected blocks in frame B satisfying a reclassification criteria are reclassified as being unconnected. Each unconnected block in frame B is categorized as being a P-block or an I-block. Values for the pixels of each I-block in frame B are calculated by spatial Interpolation based on values of nearest available neighbor pixels relative to each I-block. A residual error block for each I-block in frame B is generated.
摘要翻译：一种用于处理视频帧的方法，系统，计算机程序产品和计算机系统。一对连续视频帧的帧A和B各自包括像素块。帧A在时间上比帧B早。确定帧B中每个像素相对于帧A的像素的连接状态。连接状态是连接状态或未连接状态。帧B中的每个块被分类为未连接或单连接。满足重新分级标准的框架B中的单连接块被重新分类为未连接。帧B中的每个未连接的块被分类为P块或I块。基于相对于每个I块的最近可用相邻像素的值，通过空间插值来计算帧B中每个I块的像素的值。生成帧B中每个I块的残差错误块。
