    • The present invention provides methods and apparatus for supporting geographical-based services in a communications system. In an embodiment of the invention, a terminal node (e.g., a wireless terminal) inserts geographical information into a header portion of an IPv6 datagram. The serving network utilizes the geographical information to support a geographical-based service. In another embodiment, a terminal node, which is located in a geographical area, receives service configuration information regarding service regions from a serving network and determines what services are supported in the geographical area. In an embodiment, header formats for the inserted geographical information in a propagated signal between a terminal node and a serving network are provided.
    • 本发明提供了一种在通信系统中支持地理服务的方法和装置。 在本发明的实施例中,终端节点(例如,无线终端)将地理信息插入到IPv6数据报的报头部分中。 服务网络利用地理信息来支持地理服务。 在另一个实施例中,位于地理区域中的终端节点从服务网络接收关于服务区域的服务配置信息,并确定在地理区域中支持什么服务。 在一个实施例中,提供了在终端节点和服务网络之间的传播信号中插入的地理信息的报头格式。

    • The invention relates to the insetting of a moving picture in a moving main picture when the picture signals are in an encoded digital format. The main idea is that the picture signals are combined prior to decoding. The frames of the picture to be inset are scaled down by reducing the number of macro blocks in them in such a manner that the picture whole is retained. The macro blocks of a certain area of the main picture are replaced by the macro blocks of the reduced picture and the combined video signal is decoded. The video signals (ES1, ES2) to be combined may be picked up from different sources or extracted from a transport stream where they are in packets. The system according to the invention requires only a single decoder (210), which considerably reduces the amount of computation required by the combination of the pictures. The advantage is emphasized if there are several pictures to be combined.
    • 本发明涉及当图像信号处于编码数字格式时在移动主图像中的运动图像的插值。 主要思想是在解码之前组合图像信号。 通过以保持图像整体的方式减少其中的宏块的数量来缩小要插入的图像的帧。 主图像的特定区域的宏块被缩小图像的宏块代替,并且组合的视频信号被解码。 要组合的视频信号(ES1,ES2)可以从不同的源拾取或者从它们处于分组的传输流中提取。 根据本发明的系统仅需要单个解码器(210),这显着地减少了图像组合所需的计算量。 如果有几张图片要组合,则会强调优点。
