In an embodiment, a server may support notifications using an underlying channel-based messaging scheme. A client may register for one or more notifications from a server, or may poll the server for notifications, using messages on the channel. The notification events may be transmitted on another to the client. The flexibility of the notification system may permit distributed systems to effectively manage their notification events, in some embodiments.

Notifications

In some examples, a service receives releases including machine-readable instructions from different vendors, the releases for respective controller units of a vehicle. The service communicates the releases wirelessly to the vehicle to update machine-readable instructions executing on the respective controller units of the vehicle.

A system comprises a movie clip environment in which a movie clip object is defined, and a native application that is external to the movie clip environment. The native application renders an image to an off-screen surface of the system. A composition manager is responsive to communications from the movie clip object to control where the off-screen surface is to be rendered on a display screen. The composition manager may be responsive to communications from the movie clip object to direct the native application to control one or more properties of the image of the off-screen surface.

A system aids composited graphics rendering. A script and corresponding virtual machine engine code may be stored in memory. An off-screen buffer is generated in the memory by the script. The off-screen buffer includes an extended stage having first a buffer portion. The buffer portion may include pre-rendered graphical object. An on-screen buffer may include a composition of the pre-rendered graphical objects of the extended stage. The script renders a graphical change to the on-screen buffer using independent block copying, from the extended stage to corresponding target areas in the on-screen buffer, of one or more of the pre-rendered graphics of the extended stage area affected by the graphical changes.

A system for monitoring broadcast channels, includes a device for receiving a plurality of broadcast channels, a central search engine operable to search the received channels for a match with a pre-stored profile, a central memory connected to the search engine for storing the profile, and a plurality of user terminals connected to the search engine over a network. The search engine is responsive to commands from the user terminals to store the profiles to be searched in the memory in association with the identity of the user terminal from which the command was received. A device sends an alert signal over the network when a match is found with a pre-stored profile to the user terminal associated with the pre-stored profile. The alert signal identifies the broadcast channel matching the pre-stored profile.

A method of detecting video sequences involves creating on-the-fly candidate digital signatures uniquely characteristic of successive groups of frames in accordance with a predetermined algorithm. The candidate digital signatures are compared with at least one signature of a stored sequence created in accordance with the predetermined algorithm. A candidate is identified as corresponding to the stored sequence in the event of a positive match.

Method and apparatus for recognizing video sequences

A method of processing a video stream, involves contemporaneously selecting first and second pairs of frames in the video stream with a predetermined period. The second pairs of frames have a longer period than the first pair. For each of the first and second pairs of frames, there is determined a difference value representing the number of pixels whose value has changed between the first and second frames of the pair. A particular logic level is generated depending on whether this difference value exceeds a predetermined threshold. The generated logic levels are then compared with a decision map to identify cuts in the video stream

Method of processing a video stream

A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary records associated with each document. Each structured summary record has at least one descriptor field representative of a characteristic of the document. Predefined field entries identify a characteristic of the document. Predefined keyword criteria associated with the field entries are stored. Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field entry for the document. For example, one descriptor field might related to topic, which could have the field entries of &ldquo;financial&rdquo; or &ldquo;sports&rdquo;. The preponderance of certain keyword criteria, such as &ldquo;money&rdquo; or &ldquo;shares&rdquo; would identify the document with the financial topic.
