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.

US Classification:

341 55, 341 87, 725 39, 725 53, 707101

Abstract:

Data destined for a client is compressed at a server in a manner that produces a compressed data string that can be searched in its compressed state. The server constructs a code table that assigns codes from a standard code set (e. g. , ASCII code set) that are normally unused to selected character pairs in the data string (e. g. , the most frequently occurring character pairs). During compression, the selected character pairs are replaced with the corresponding codes. Identifiers are inserted into the compressed data string to separate substrings. To search the compressed data string at the client, a search query is compressed and compared to the compressed substrings. The substring identifiers are used to quickly locate each successive compressed substring. When a match is found, the matching substring is decompressed by replacing the code in the compressed substring with the corresponding character pair in the code table.

Abstract:

Replaying a compressed digital video stream in fast-forward and reverse modes at varied playback rates. An index of interceded frames, those frames not dependant on other frames for generation, is stored. The index includes the size of intercoded frames and their storage location. When a specified playback rate is requested, the intercoded frames are retrieved using the index. The interceded frames then have one or more intracoded frames, frames that reference other frames for generation, placed between them to generate a frame sequence. The intracoded frames are “blank,” meaning they contain only information from their associated interceded frame. By inserting “blank” frames specified playback rates and bit rates are generated. The index of interceded frames may also be accessed to generate playback in reverse mode, which conserves memory resources of associated systems by generating the reverse playback stream in an iterative manner.

US Classification:

709204, 725 32, 715758

Abstract:

Reducing the amount of input required by a user to enter an electronic message. When an electronic message is received, one or more language expressions associated with the electronic message are displayed to a user. The user may select one or more of the language expressions and have the full text of all the selected language expressions included in a reply electronic message. Icons, which represent a user's capability to engage in an electronic messaging session, may also be displayed. When a user changes their capability to engage in an electronic messaging session, for instance when they go offline, a command may be sent to other users. This command may take the form of a character sequence not normally occurring in written language, which is interpreted by network devices and changes the display of the icon associated with a the user who went offline.

Abstract:

In a system that includes a processor and a display device on which video programming can be displayed, a method for transitioning to a video advertisement by displaying a related banner advertisement. The method includes generating, on the display device, a display screen on which a video advertisement is to be displayed, the display screen being generated at a time before a time at which the video advertisement is available to be displayed. A banner advertisement is displayed on the display screen at a region that coincides with a region where the video advertisement is to be displayed. The banner advertisement can have a subject matter that is related to that of the video advertisement or alternatively have any subject matter. When the video advertisement becomes available to be displayed, the method can include replacing the banner advertisement with the video advertisement.
