Abstract

An on-line multiple media viewer system provides a responsive interactive presentation at a client viewing station of multiple media content retrieved over a remote connection from a server at which the content resides using a set of client-initiated and server-driven remote services for anticipatory caching of media content. In response to an initial request for an item of media content from the server, the remote services predict additional items of media content likely to be requested and transmit these items in advance of their request. Transmitted items are cached by services at the client viewing station in a cache storage. The client checks the cache storage before making additional requests for transfer over the remote connection. The items are transmitted in multi-channel asynchronous operations over the remote connection.

Claims

1. In a distributed computer network comprising a remote multiple media content server and a client viewing station in communication via a wide-area connection, a method of viewing at the client viewing station a multiple media title stored at said server and containing a plurality of topics associated with multiple media items, the method comprising the steps of:

receiving at said server a first request by the client viewing station for data relating to a selected one of the topics contained in the multiple media title;

determining from multiple media items associated with the selected topic and responsive to the first request which of the multiple media items of the topic are likely to be requested next by the client viewing station;

transferring from said server to the client viewing station of said multiple media items determined as likely to be requested next; and

caching said transferred multiple media items in a cache storage at the client viewing station whereby said multiple media items are available without requesting from said server when rendering a presentation of at least a portion of the topic at the client viewing station.

2. The method of claim 1 comprising:

checking by the client viewing station for the presence in the cache storage of multiple media items needed for rendering the presentation at the client viewing station without the client viewing station having previously requested the multiple media items; and

retrieving from the cache storage by the client viewing station any said multiple media items needed for rendering the presentation and present in the cache storage.

3. The method of claim 1 wherein said step of determining is performed at said server in response to the client viewing station requesting an address datum relating to the topic.

4. The method of claim 1 wherein the wide-area connection is capable of multiple channel communication and said transferred multiple media items comprise a bitmap image element having associated dimension data, and the method comprises:

transferring the bitmap image element and the dimension data from said server to the client viewing station in separate channels.

5. The method of claim 4 wherein said transferred multiple media items further comprise a textual element, and the method comprises:

transferring the bitmap image element and the textual element from said server to the client viewing station in separate channels.

6. The method of claim 1 wherein the wide-area connection is capable of multiple channel communication, and further comprising the steps of:
