    • The present invention provides a system and method for providing enhanced features for streaming video-on-demand systems. The system comprises a media server and a client player, wherein a user can select a desired video for transmission from the media server to the client player for subsequent display for the user via the client player. The system comprises a mechanism that enables a user to interactively select a desired new starting point for the display of the selected video signal. The mechanism is provided by a first and second series of searchable index frames, wherein the first series is generated by the media server during transmission of the selected video signal and the second series is generated by the client player during receipt of the selected video signal. Upon receipt by the client player of the desired new starting point, the first or second series are accessed in order to identify a required searchable index frame that best represents the desired new starting point. Display of the video by the client player subsequently commences from the required searchable index frame.
    • 本发明提供了一种用于提供用于流式视频点播系统的增强特征的系统和方法。 该系统包括媒体服务器和客户端播放器,其中用户可以选择所需的视频以从媒体服务器传送到客户端播放器,以便随后通过客户端播放器显示用户。 该系统包括使得用户能够交互地选择所需新的起始点以显示所选择的视频信号的机制。 该机制由第一和第二系列可搜索的索引帧提供,其中第一系列由媒体服务器在所选择的视频信号的传输期间产生,并且第二系列由客户端播放器在接收所选择的视频信号期间产生。 当客户播放器收到所需的新起始点时,访问第一或第二系列以便识别最能代表期望的新起始点的所需可搜索的索引帧。 客户端播放器随后从所需的可搜索的索引帧开始显示视频。
