摘要： The invention teaches a method of positioning a first image (10) having a first image format into a second image (30) comprising multiple image blocks (40) and having a second image format. A straight boundary (46) of at least one image block (40) in the second image (30) is identified. The first image (10) is positioned into the second image (30) by aligning an edge (16) of the first image with the identified straight boundary (46). Alternatively, a block row (22) or column (24) of the first image (10) can be aligned with the straight boundary (46) but then in such a way that an edge (16) of the first image parallel to the block row (22) or column (24) is aligned with a boundary of a row (42) or column (44) of image blocks (40) in the second image (30). This image positioning reduces any bleeding artifacts and the number of bits required for representing the image (30) during encoding.

摘要： Today's computer programs that convert raster images into vector-based images do not optimize/compress the vector representation of the vector-based images. Instead, they simply keep all of the complex edges for the vector objects within the vector-based images. The present invention described herein functions to create a compressed vector-based image by simplifying the shapes of common complex edges which are shared by adjacent vector objects. The compression (lossless compression) of the vector objects is done without affecting the perceived quality of the vector-based image.
摘要翻译：今天将光栅图像转换为矢量图像的计算机程序不会优化/压缩基于矢量图像的矢量表示。相反，它们只是将基于矢量的图像中的矢量对象的所有复杂边缘保留下来。本文描述的本发明通过简化由相邻矢量对象共享的公共复合边缘的形状来创建基于压缩矢量的图像。完成矢量对象的压缩（无损压缩），而不影响基于矢量的图像的感知质量。

摘要： A multimedia provider (100) multicasts a main multimedia stream (10) comprising a mixture of intra (12) and inter frames (14, 16, 18) and multicasts an associated auxiliary stream (20) comprising intra frames (22, 24). At least a portion of the intra frames (24) in the auxiliary stream (20) are generated based on same multimedia data as at least a portion of the inter frames (14) of the main stream (10). The provider (100) also transmits a stream information channel (30) comprising information (32, 34) descriptive of time instances of intra frames (12; 22, 24) in the main (10) and auxiliary (20) streams. This information (32, 34) allows a set top box (200) to selectively connect, in connection with session set-up and channel switch, to the main (10) or auxiliary (20) stream to receive an intra frame (12; 22, 24) with as a low delay as possible.
摘要翻译：多媒体提供商（100）多播包括帧内（12）和帧间（14,16,18）的混合的主多媒体流（10），并且多播包括帧内（22,24）的相关辅助流（20）。基于与主流（10）的帧间（14）的至少一部分相同的多媒体数据来生成辅助流（20）中的帧内（24）的至少一部分。提供者（100）还发送包括在主（10）和辅助（20）流中描述帧内（12; 22,24）的时间实例的信息（32,34）的流信息信道（30）。该信息（32,34）允许机顶盒（200）与会话建立和信道切换有选择地连接到主（10）或辅助（20）流以接收帧内（12; 22,24）尽可能低的延迟。
