摘要:
A voice activity detector (VAD) which determines whether an input signal contains speech by deriving parameters measuring short term time domain characteristics of the input signal, including the average signal level and the absolute value of any change in average signal level, and comparing the derived parameter values with corresponding predetermined threshold values. In order to further minimize clipping and false alarms, the VAD periodically monitors and updates the threshold values to reflect changes in the level of background noise.

The present embodiments provide methods, systems and apparatuses for use in managing content on at least a local network. Some embodiments provide a method for use in managing content that detects there is a change to content on a local network, determines whether the change is additional content on a first client device, determines whether the additional content can be identified, determines whether there is a predictive distribution scheme when the additional content is identified, distributes the additional content over the local network according the predictive distribution scheme when a predictive distribution scheme applies to the additional content, determines whether a new predictive distribution scheme can be defined when a predictive distribution scheme does not apply to the additional content, and saving the new predictive distribution scheme when a new predictive scheme can be defined.

The present embodiments provide methods, systems and apparatuses for use in managing content on at least a local network. Some embodiments provide a method for use in distributing content that receives a request to deliver premium content over a distributed network; identifies a location relative to where the request is made; determines whether there is a first additional content associated with the location; adds the first additional content to the requested premium content when there is the first additional content associated with the location; and distributes the requested premium content and the first additional content according to the request.

A system, method and article of manufacture are provided for remotely controlling content stored on a local computer connected to a network system such as the Internet. The invention allows content such as DVD Video content to be locked so that play can only be accomplished through verification of user identity and also allows augmentation and supplementation of the content provided by the video from a remote server. In addition, upon verification of user client credentials, the present invention allows the locally stored content to be supplemented with additional content delivered over the network system. Furthermore, the present invention allows content stored locally on a client device to be remotely controlled to play synchronously on a plurality of client devices.
摘要:
A content tracking system consists of a multi-level distributor network including a primary level distributor and a second level distributor for distributing content embodied in a storage medium. A server is included for receiving a tracking identifier that is incorporated with the content embodied in the storage medium and for receiving registration information from the primary level distributor and the second level distributor. The content tracking system includes a database for associating the particular content with the primary level distributor and the second level distributor and for associating transactions derived from the content on the storage medium with the primary level distributor and the second level distributor. The content tracking system is capable providing credit to the primary distributor and the second level distributor for transactions derived from the content after being distributed by the second level distributor.

A method for timing correction in a communications receiver includes the steps of (a) setting a timer to a known value; (b) defining a first window by defining a first rollover value; (c) defining a second window by defining a second rollover value; (d) defining a first receive gate transition relative to the first rollover value; (e) defining a second receive gate transition relative to the second rollover value; (f) starting the timer; (g) receiving a first receive burst in the first window; (h) receiving a second receive burst in the second window; (i) if a first receive burst is received after the first receive gate transition, increasing the second rollover value, and decreasing the first rollover value by an equal amount; (j) if the first receive burst is received before the first receive gate transition, decreasing the second rollover value, and increasing the first rollover value by an equal amount; (k) if the second receive burst is received after the second receive gate transition, increasing the first rollover value, and decreasing the second rollover value by an equal amount; (l) if the second receive burst is received before the second receive gate transition, decreasing the first rollover value, and increasing the second rollover value by an equal amount; (m) if the first receive burst is received after the second receive gate transition, and the second receive burst is received after the second receive gate transition by a similar amount, increasing one of the first rollover value and the second rollover value at least one frame and then restoring the one of the first rollover value and the second rollover value; (n) if the first receive burst is received before the first receive gate transition, and the second receive burst is received before the second receive gate transition by a similar amount, decreasing one of the first rollover value and the second rollover value at least one frame and then restoring the one of the first rollover value and the second rollover value; (o) if the first receive burst is received time-shifted relative to the first receive gate transition, and the second receive burst is received time-shifted relative to the second receive gate transition by a different amount, adjusting the second rollover value including: if the second receive burst is received after the second receive gate transition, increasing the first rollover value, and decreasing the first rollover value by an equal amount; and if the second receive burst is received before the second receive gate transition, decreasing the first rollover value, and increasing the second rollover value by an equal amount; and then adjusting the first rollover value including: if a first receive burst is received after the first receive gate transition, increasing the second rollover value, and decreasing the first rollover value by an equal amount; and in the event the first receive burst is received before the first receive gate transition, decreasing the second rollover value, and increasing the first rollover value by an equal amount; and then adjusting the first rollover value to match an error between the second receive burst and the second receive gate transition.
摘要:
A media services interface for use in a readable medium playback device enables synchronization of disparate media playback, network directed playback of media, media playback control via displayed html/javascript file, logging of consumer identifier, media identifier, and playback device identifier in a cookie or log file. The media services comprises a command handler, a properties handler, an event generator, a cookie manager, a navigator state module, an identifier engine, an initialization module, and a bookmark manager. The command handler executes commands received from a connected network, a displayed html/javascript file, etc. The properties handler provides information relating to system states in response to queries including the status of any network connections. The event generator generates events in response to predetermined system occurrences. The cookie manager records information for later reading including the tracking of consumer identifier, playback device identifier, and readable medium identifier triples. The navigator state module maintains information regarding the state of the playback device and the interaction with the readable medium. The identifier engine carries out determination of the identity of the readable medium. The initialization module controls system initialization. The bookmark manager generates bookmarks which preserve positions in the playback of the readable medium for later recall. Network sources can provide media content and issue commands which synchronize the playback of both network and readable medium originated content over multiple playback devices through the use of the synchronization abilities of the media services.
