Abstract: A data sharing methodology and structure for communication between users of digital Internet-accessible devices, such as set-top boxes, is described. Users of Internet-accessible devices can establish connections between trusted users of other Internet-accessible devices and transfer personal information using either the Internet or the public switched telephone network (PSTN). Some examples of the type of information that may be transferred include IP addresses, e-mail, multimedia objects, and voice data. Once personal identification information has been exchanged, future communications may be easily re-established and maintained.

Abstract: On-screen-display graphics data is transmitted from a source device to a display device over an IEEE 1394-1995 serial bus network utilizing an isochronous data format. The on-screen-display graphics data is generated by the source device and transmitted to a display device, as a stream of isochronous data, separate from video data. Each packet of isochronous data within the stream of on-screen-display graphics data includes an address value corresponding to a memory address within the display device forming a buffer. When received by the display device the on-screen-display graphics data is loaded into the appropriate memory locations within the buffer corresponding to the address values. At the display device, an embedded stream processor is utilized to strip the header information from each packet and determine the appropriate memory location that the data is to be stored. A trigger packet is sent at the end of the data stream for a screen of on-screen-display graphics.

Abstract: An encryption arrangement for television programs or other digital programming consistent with certain embodiments sends content completely in-the-clear and also encrypts only a portion of the content required for full presentation of a television program. The arrangement allows interoperability between new TVs that can handle encryption and older TVs that cannot. Regulations prevent new TVs from receiving only the clear content. New TVs are made to descramble the encrypted portions of the content. Older legacy TVs can receive all the content in the clear. The encrypted portions are chosen so that dramatically less bandwidth is required as compared to full dual carriage of the content. Licensing provisions relating to the encryption technology can be used to control unauthorized use of content. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Abstract: Embodiments of the present invention include a method and apparatus for using, operating, and controlling audio/video equipment in a wired or wireless home network using a remote control unit. One embodiment of the invention allows legacy audio/video devices to be included in the home network. An adapter converts analog video and analog audio to digital from one device, multiplexes the digital signals, and converts the multiplexed signal to a format compatible with the home network transmission medium. The adapter also de-multiplexes and converts digital signals back into analog video and analog audio. The adapter also conveys optical pulses from a legacy device's remote control unit across the network.

Abstract: Embodiments of the present invention include a method and apparatus for communication of infrared pulse sequences, typically emitted by remote control units associated with audio/video equipment, across a wired or wireless home network.

Abstract: A combined IEEE 1394-2000 and ethernet network allows devices on the network to operate according to both the IEEE 1394-2000 protocol and the ethernet protocol. The devices within the network are able to send IEEE 1394-2000 ischronous data, IEEE 1394-2000 asynchrounous data and ethernet data. Both IEEE 1394-2000 and ethernet devices within the network are coupled to modified hubs (MHUBS) to form a local cluster. The MHUBS are coupled to an ethernet switch which controls communications between devices in different local clusters. The ethernet switch and the MHUBS obey an ischronous interval in which all isochronous data transfers and asynchronous data transfers from ethernet devices with an allocation of reserved bandwidth will be allowed. Preferably, on a regular and reoccurring period, the ethernet switch sends an isotick signal to begin the ischronous interval.

Abstract: A television set-top box used as a point of sale terminal at a retail establishment such as a department store or kiosk. The television set-top box may include a swipe card reader and is coupled to a television display, an input device and a printer. The customer accesses a catalog database of merchandise and inventory using a user interface to point of sale software. The customer may also enter an order using order entry software forming a part of the point of sale software. The catalog database is situated on a disc drive within the set-top box and can be updated from a catalog server as required to maintain accurate inventory and merchandise information in one embodiment. In another embodiment, the set-top box operates in a client mode to access information from the catalog server.

Abstract: An adaptive user interface and method thereof for simplifying the use of new electronic devices, such as set top boxes, by adapting the user interface on the basis of usage history. The adaptive user interface monitors input commands to the user interface and tracks usage statistics for use in determining whether to add or remove features from the interface. A ramp-up embodiment of the invention automatically adds user interface features as the user becomes more proficient with a device. A ramp-down embodiment of the invention automatically removes seldom used interface features. By tracking users' actions, the user interface can more accurately be modified to fit actual use habits of each user, rather than relying on user perception of what functionality is used.

Abstract: An apparatus for partitioning, scaling and displaying video and/or graphics across several display devices includes a video source, a master device and multiple display devices arranged into a multiple display configuration. Preferably, the master device partitions the video stream into image sections and assigns each display device a corresponding image section based on its position within the multiple display configuration. Each display device then preferably receives the video stream and separates the data representing the corresponding image section. Preferably, once the data for the corresponding image section is separated, the display devices then scale their respective image sections to a full screen size image and display the scaled image simultaneously with the display of the entire frame on all display devices within the multiple display configuration.
