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.

Embodiments of the present invention disclose a method and system for protecting the security of encrypted software. Specifically, the present invention pertains to a method of decrypting only those steps or portions of the software that are written to a processor's internal instruction cache. While in storage in non-volatile memory and in RAM, encrypted software remains in an encrypted state. The invention includes a decryption unit that may be located internal to the processor and performs decryption of the software as it enters the instruction cache. By use of this method, encrypted software is resistant to copying from RAM in a decrypted state for subsequent reverse engineering. Software that is protected by this method could be any intellectual property meant to processed by computer that is delivered to the user by internet, cable, direct satellite, packaged media, or any other means.

A method and apparatus for optimizing picture quality of a video signal. The method includes displaying a user menu having a plurality of choices of video labels; receiving a choice of video label from the plurality via an input from a user; translating the video label into a label code; receiving at least a first video processing parameter from a look-up table corresponding to the label code; and configuring a video processor according to the first video processing parameter. The apparatus includes a microprocessor; a memory associated with the microprocessor, the memory for storing video parameters associated with video processing; a video input selector coupled to a plurality of video inputs, the video input selector also coupled to the microprocessor to receive a choice of video inputs therefrom; and a video processor connected to the microprocessor for receiving video parameters therefrom, the video processor also coupled to the video input selector to receive a video signal therefrom and to condition the video signal using the video parameters. The invention may be implemented in software, hardware, firmware, microcode, and other such media.
摘要:
A method for processing audio from varying audio sources includes providing a variable audio response, including audio gain, balance and tonal quality setting on a per channel (or per source or both) basis that a user can adjust when setting up the receiver. For example, a user can establish a relative gain setting from null4 dB to null4 db in 2 dB increments, increment rear volume while increasing base response for the audio so that the audio is compensated in accordance with this setting before sending the audio to the speakers. This enables a user to account for those channels or sources that are out of the normal for the user in terms of loudness and tone, i.e., either the channels are too loud or too soft relative to most of the other channels or sources. Each channel or source would be preset to 0 dB, thereby providing no compensation. According to this method, the user first sets his volume control to a place where the user finds satisfactory. Then, when the user tunes to a given channel or source and notices that this channel typically requires the user to adjust the volume (either up or down), the user can adjust the automatic audio gain setting for this channel to account for this deviation. Other possible gain settings could be from null10 dB to null10 db in 1 dB or 2 dB increments, just to name one possible example. The user can also adjust the balance, tonal quality and other aspect of the audio signal as desired.
摘要:
Methods for enhancing the performance of quantization operations by converting division operations to a combination of multiplication and shift operations, which are preferably performed on a processor supporting single-instruction multiple-data (SIMD) instructions. A table of mantissa and exponent values is created for a sufficient range of values for 1/a. During quantization, the mantissa and exponent values are found in the table 1/a for associated with a given quantization division operation given by b/a which is found according to the formula b/anull(bnullA)>>n. Aspects are described for application to processors that do not support non-uniform shift operations, and for reducing the necessary bit-width of the operations to increase efficiency. The quantization method may be applied to protocols such as MPEG-2 and other similar formats.
