A system and method for augmenting digital material with MPEG-7 content descriptions to enhance searching and selection of the digital material. Pursuant to the collection of content information about the digital material, either through receipt or content characterization, a set of MPEG-7 descriptor schemes and descriptors are created for constituent elements of the content. The MPEG-7 descriptions are structured as META tags, including predetermined opening and closing delimiters, which are inserted within the header field of the digital material. The MPEG-7 content description data may contain multiple content levels describing levels of associated embedded content. By way of example, use of MPEG-7 content descriptions within a web site (or internet transaction session) can improve the speed and accuracy of content selection.

A network architecture for a network of electronic devices includes a device layer having a plurality of electronic devices interconnected using a network backbone, wherein the plurality of electronic devices each operate using a device native communication protocol. The architecture also includes a device abstraction layer (DAL) which communicates with each of the devices using the device native communication protocols and also presents a unified communication interface to a content abstraction program interface. The content abstraction program interface communicates with the device layer through the unified communication interface of the DAL and includes a set of content services for controlling content on the network. In one embodiment the content abstraction program interface includes a content location system (CLS), a content change notification system (CCNS), and a content engagement system (CES).

A method is disclosed for providing an evaluation of a plurality of information sites to a user over a packet-switched network when the user submits a search request through a user interface device in communication with the packet-switched network. The method begins by acquiring a search result, responsive to the search request, which includes network addresses for the plurality of information sites. Next, a plurality of individuals are selected who were previously in communication with at least one of the information sites over the packet-switched network and who meet at least one predefined criterion selected by the user. A plurality of evaluations of at least one of the information sites is retrieved from a database, which are provided by the plurality of individuals. Finally, a rating based on the evaluations is forwarded to the user over the packet-switched network.

A method for displaying a status to a television viewer provides detailed information to a viewer. According to the method, signal strength of a received RF signal is evaluated, and an RF signal strength indicator value is created. The RF signal strength indicator value can be a qualitative indicator, such as strong, good, normal, weak, or absent. The RF signal indicator value can also be a qualitative value. A transport signal is also evaluated and a transport signal validity indicator value is then created. A quantitative value could be obtained based on the bit error rate, for example. Additionally, received parsing information is evaluated and a parsing validity indicator value is created. As with the transport signal, the received parsing information can be evaluated to obtain a qualitative indicator, such as valid or invalid. The RF signal strength indicator value, the transport signal validity indicator value and the parsing validity indicator value are displayed automatically if television programming is not being displayed or detected when programming a channel map or under control of a user. So, if the programming fails to display or be detected, these status values are displayed in place of a blank screen.

A video scaler optimizes the display properties of an image so that as little image is lost as possible while occupying as much of the screen as possible. By so doing, a high definition image can be made larger without losing all of edges of the picture. According to one aspect of the present invention, a method for displaying a 16:9 aspect ratio image on a 4:3 aspect ratio screen provides that the image is proportionally increased so that approximately 13% of the image is lost at the sides while approximately only 13% of the screen is unused at the top and bottom. Similarly, a method for displaying a 4:3 aspect ratio image on a 16:9 aspect ratio screen provides that the image is proportionally increased so that approximately 13% of the image is lost at the top and bottom while approximately only 13% of the screen is unused at the sides. According to yet another aspect of the present invention, the viewer can control the scaling ratio of the image so that the percentage of lost image varies from zero to its maximum, e.g., 25% for a 4:3 aspect ratio image and a 16:9 aspect ratio screen.
摘要:
A method of providing and enabling a dynamic and scaleable system architecture for a computer system is disclosed. The method is executed on a computer system having a processor, a computer readable memory, and an adapter for receiving a module that will add functionality to the computer system. The processor is coupled to the computer readable memory and to the adapter. The method is implemented on the computer system by storing program instructions on memory and executing them via the processor in conjunction with other components of the computer system. The method comprises several steps, starting with a first step of detecting the availability of a new function. Next, an input interface specification and an output interface specification for the new function is received by the computer system. In the next step, it is determined whether a first available function has an output interface specification that is compatible with the input interface specification for the new function, and whether a second available function has an input interface specification that is compatible with the output interface specification for the new function. The new function is then selectively enabled if the interface specifications are compatible.

Methods for realizing advanced graphical user interface (GUI) in panel subunit. The present invention provides, in one embodiment, a button GUI element descriptor that defines a bitmap to be displayed when a button is out of focus and another bitmap to be displayed when the button is in focus. In another embodiment, the present invention provides a table GUI element descriptor that defines a table-like on screen display to be displayed on the contoller device. Another embodiment of the present invention provides a panel GUI element descriptor that includes a focused identifier attribute indicating a pre-determined element of the on-screen display as default focus. In this way, the target device would be able to control the default focus of the controller device when displaying an on-screen display. In yet another embodiment, the present invention provides a text GUI element descriptor that includes a font style attribute that dictates whether the text GUI element should be displayed as bold, underlined and/or reversed. By using these extended elements in panel subunit, more complicated and advanced GUI, such as an electronic programming guide (EPG) can be achieved.
