International Classification:

H04N 716

US Classification:

725152, 725 54, 725143

Abstract:

A system for distributing digital data over a video channel to a plurality of remotely located client terminals. The system involves selecting a set of digital data to be distributed and converting it to an intermediate format compatible with video broadcast. The intermediate data is then broadcast over a video channel during a time when no video content is being transmitted so that the intermediate format data takes the place of the video content. The intermediate format data is received at a remotely located client terminal where the set of digital data is recovered.

International Classification:

US Classification:

709203, 709202, 709217, 709219, 709227, 709228, 709229, 707 9, 707 10, 713200

Abstract:

A server system provides a client system with a number of on-line services including a log-in service. Once the server receives a request from the user for initiating access to the server, the log-in service accesses a user database for information including access privileges of the authorized user in relation to the other services available on the server. The server then generates an information packet containing this information, and transmits the information packet to the client. The client than transmits a second request to the server, requesting use of another service offered by the server. The information packet provided by the server in response to the log-in request is transmitted along with the second request to the server. The server then regulates access by the client to this other service by using the information packet transmitted back to the server from the client. Thus, access to the user database is minimized.

Inventors:

Stephen G. Perlman - Palo Alto CA

Assignee:

WebTV Networks, Inc. - Mountain View CA

International Classification:

H04N 1100

US Classification:

348460, 725 19, 358908

Abstract:

A method and system are described for identifying video segments (e. g. , commercials or television programs) without using any identification data that may or may not be provided in the non-displayed overscan portion or the vertical blanking interval of the video signal. Instead, the video segment is identified by recognizing patterns in the viewable portion of the video image data and/or in the video sound data. If the pattern is unique to a specific video segment, that video segment is identified by, for example, looking up the pattern in a table correlating patterns with video segment identifications. Any number of functions may be performed using this identification.

International Classification:

G06F 1516

US Classification:

709217, 709227

Abstract:

A system for targeting information on a computer network. The system involves categorizing a plurality of address pointers according to the content designated by the address pointer. The system further involves reading the address pointer which designates the content received by the user and determining which category or categories, if any, the address pointer is within. Information packets, such as advertisements, are targeted to selected categories. Once the category of an address pointer has been determined, an information packet targeted to that category is selected and transmitted to the user.

International Classification:

US Classification:

709219, 709203, 709217, 709228, 709229, 709246

Abstract:

A method is described of providing a document to a client coupled to a server. The server functions as a proxy on behalf of the client for purposes of accessing a remote server. In the method, a document is retrieved from the remote server in response to a request from the client. The document includes data to be used by the client in generating a display. The proxying server alters (i. e. , transcodes) the data in the document to form a transcoded document. The transcoded document is then transmitted to the client. The proxying server transcodes the data in the document in order to perform at least one of the following functions: (1) matching decompression requirements at the client; (2) converting the document into a format compatible for the client; (3) reducing latency experienced by the client; and (4) altering the document to fit into smaller memory space.

Appl. No.:

Inventors:

Assignee:

Webtv Networks, Inc. - Mountain View CA

International Classification:

H04N 591

US Classification:

386 83, 386 46

Abstract:

A video system receives an instruction to perform a function such as a display or record operation. Computer-executable instructions are for determining the status of a toggle setting (e. g. , ON/OFF or TV/VIDEO status) of a video recorder (e. g. , a VCR), and for ascertaining whether the toggle setting of the video recorder needs to be toggled to perform the function. The instructions are also for transmitting a toggle instruction to the video recorder if needed to perform, for example, the display or record operation. Thus, the setting of the video recorder automatically occurs without requiring complex user interaction.
