摘要:
A media server comprises a plurality of nodes each comprising a gateway, each gateway providing memory and communication of data between mass storage and I/O ports of a node, and/or providing communication of data between the node and other nodes. Each node utilizes one or more central processors. The media server comprises logic to enable the processors to manage the streaming of data from the mass storage to the I/O ports via the gateways without communicating the data between the processors and any of the mass storage, I/O ports, or gateways.

Methods and apparatuses for controlling a bias point voltage for an external optical modulator are provided. A control loop is used to adjust a bias signal applied to an external modulator by determining unwanted signals at a predetermined frequency received by an optical receiver of the control loop and accounting for these unwanted signals when determining the bias point voltage.

A method includes reading selected portions of video content from a digital versatile disk (“DVD”), said selected portions of video content separated by periods of time to provide a fast forward or rewind mode; generating a transport stream of transport stream packets containing said selected portions of video content; and in response to detecting said fast forward or rewind mode, causing a transport stream decoder to decode said transport stream packets without synchronization.

Using an identifier generation algorithm, a device coupled to a communication network generates an SSID and associated encryption key for a mobile device using its unique identifier. The encryption key and SSID are stored to a configuration database server coupled to the network. A wireless-capable device that provides access to the network receives the SSID and encryption key from the configuration database and sends a broadcast message that includes the SSID and unencrypted original information. The mobile user device receives the broadcast message when it enters the presence of the wireless access device. Using the identifier generation algorithm the mobile device generates an SSID and key from its unique identifier and encrypts the original information and sends a return message including the SSID and the encrypted original information. The mobile device is granted access if unencrypted original information from the return message matches that sent in the broadcast message.

A name that means something to a human can be used to provision multiple channels, multiple times after a one-time association of an binary integer mask bit pattern with the name, or mnemonic. Typically, the one performing the one-time association of the mask pattern with the mnemonic will choose a name that reflects the channel attributes represented by the mask pattern. Thus, rather than remembering a bit pattern for a single attribute, or even the more difficult task of remembering the pattern for multiple attributes, and having to make sure a ‘1’ is placed in a correct bit position among many ‘0’s when entering bit patterns, the one provisioning only enters a mnemonic that textually refers to the attribute, or attributes, to be provisioned for a given channel.

A method of upgrading the software load of a device includes receiving a configuration file and checking if a device software load matches load information (EE) of the configuration file. If the device software load does not match the EE of the configuration file, a check is made to determine if the device software load matches new load information (NE) of the configuration file.

Methods for providing adaptive equalization in the presence of a burst error are provided. If an equalization algorithm has converged and burst errors are present during a symbol interval, the equalizer coefficients remain unchanged during the symbol interval. If the burst error is no longer present during the next symbol interval, the equalizer coefficients are updated based on the previously converged coefficients.

In DOCSIS 3.0 a greater level of configuration is possible for cable modems than was available in earlier versions. The CMTS potentially receives many possible configurations from a new CM. The standard does not indicate how the CMTS should configure a CM that can support more than one possible configuration. A CMTS' operator specifies preferences for certain channel configurations. The CMTS evaluates the configuration profiles received from a booting CM and determines the best profile to attempt to accommodate based on the specified preferences. The CMTS determines how to instruct the CM to configure itself based on the available channel resources than can accommodate the selected configuration profile.

An in-context interactive television ticker is provided. The ticker is rendered on a display screen that also shows a television program, and presents ticker content that is in-context with subject matter of the television program. The ticker remains rendered and context-sensitive to the subject matter of the currently shown television program, whenever there is a change in the television program, such as when the subject matter of the current television program changes, when a commercial interruption occurs during the television program, or when the television channel is changed. The ticker is interactive in that the viewer can perform various interactive operations with the ticker, including interacting with the ticker to obtain additional information related to an in-context item presented by the ticker.
摘要:
A system and method for generating a mosaic image stream, the method includes: retrieving, at a retrieval rate responsive to an encoding rate of a primary stream, mosaic frame information that comprises a primary frame and multiple secondary frames; generating a mosaic frame from the mosaic frame information; and repeating the retrieving and generating to provide a group of mosaic frames; wherein if a reception rate of a certain secondary stream is slower than the retrieval rate then the retrieving comprises re-fetching a secondary frame of the certain secondary stream; and wherein if a reception rate of a certain secondary stream is slower than the retrieval rate then the retrieving comprises ignoring a group of secondary frames of the certain secondary stream.
