Client computer(s) retrieve and display synchronized annotated multimedia streams from servers dispersed over a diverse computer network which includes local area networks (LANs) and/or wide area networks (WANs) such as the internet. Multimedia streams provided to the client computer(s) can include a compressed video stream for display in a video window and an accompanying compressed audio stream. Annotations, i.e., displayable events, include textual/graphical data in the form of HTML pages with Java applets to be displayed in one or more event windows. The video/audio and annotation streams are produced and then stored in stream server(s). Annotation streams include annotation frames which provide either pointer(s) to the event(s) of interest or include displayable data embedded within the annotation stream. Accordingly, each annotation frame includes either an event locator or an event data. In addition, each annotation frame includes an event time marker which corresponds to the time stamp(s) of associated video frame(s) within the video stream. Examples of embedded displayable data include ticker tape data embedded within the annotation stream. Examples of event locators to displayable events include URL addresses pointing to HTML web pages. Video/audio streams and annotation streams are provided by the stream server(s) to the client computer(s) in a coordinated manner, so that the client computer(s) is able to synchronously display the video frames and displayable event(s) in a video window and event window(s), respectively.
In a client computer having a processor, memory and a display device, said client computer coupled to a stream server and at least one web server via a network, a method for synchronizing the display of video frames of a video stream with the display of displayable events, said method comprising the steps of:
In a stream server having a processor and memory, said stream server coupled to a client computer and at least one web server via a network, said client computer having a processor, memory and a display device, a method for streaming video and annotation streams to synchronize the display of video frames of a video stream with the display of displayable events, said method comprising the steps of:
In a client computer having a processor, memory and a display device, said client computer coupled to a stream server via a network, a method for synchronizing the display of video frames of a video stream and the display of a plurality of displayable events, wherein said video stream and said plurality of displayable events are to be displayed concurrently in a video window and an event window, respectively, of said display device, said method comprising the steps of:
In a stream server having a processor and memory, said stream server coupled to a client computer via a network, said client computer having a processor, memory and a display device, a method for streaming video and annotation streams to synchronize the display of video frames of said video stream with the display of a plurality of displayable events, wherein said video stream and said plurality of displayable events are to be displayed concurrently in a video window and a first event window, respectively, of said display device, said method comprising the steps of:
