20130227623 | identifying a signal route for delivery of video-on-demand to a subscriber terminal - “A set top box includes an interface to a video on demand system, the interface adapted to receive communications from one or more modulators of a modulator group of the video on demand system. The set top further includes a decoder configured to extract a modulator group identifier periodically inserted into communications directed the set top box from the one or more modulators, the modulator group identifier unique to a physical transmission path from a headend of the video on demand system to the one or more modulators. The set top includes a video-on-demand request interface to the video on demand system, the video on demand request interface configured to output a request for video on demand data including the modulator group identifier.” | 08-29-2013 |
20090297153 | Four quadrant linearizer - A system includes a laser generator, and a signal distortion generator circuit inline with the laser generator modulation signal and configured to generate distortion vectors in any of four distortion vector quadrants. | 12-03-2009 |
20090288124 | SMART CAROUSEL - A data carousel exists as an out-of-band carousel (OOBC), and accessed as a hidden background service from the channel map, and that discriminates against metadata that is never (or is rarely) accessed, and that is acquired in the background, filling a cache even when the subscriber is not accessing Video on Demand. | 11-19-2009 |
20090265468 | Fair Bandwidth redistribution algorithm - A process of managing bandwidth in a computer network having normal users and users that consume a disproportionate amount of bandwidth includes creating bandwidth gates for m users causing disproportionate traffic on the network, each bandwidth gate providing a bandwidth of y, and setting m to a minimum and y to a maximum for the set m. | 10-22-2009 |
20090202255 | ABSTRACT OPTICAL RECEIVER WITH AUTOMATIC DISTORTION CANCELLATION - An optical receiver includes closed-loop composite second order (CSO) distortion correction logic. An optical communication system includes a transmitter comprising open-loop composite second order (CSO) distortion correction logic, and a receiver comprising closed-loop composite second order (CSO) distortion correction logic. | 08-13-2009 |
20090193137 | DYNAMIC QUALITY ADJUSTMENT BASED ON CHANGING STREAMING CONSTRAINTS - A method and apparatus for dynamic quality adjustment of digital media based on changing streaming constraints is provided. A digital media server sends a digital media stream according to a set of streaming constraints to a requesting client. Audio and visual information may be sent to a requesting client together in a single stream, or separately in multiple streams. A client sends a request over a control network to the digital media server indicating information of a particular type is no longer desired. In response to receiving the signal, the video server ceases transmission of that particular type of information to the signaling client, thus relaxing streaming constraints. As a result of the techniques described herein, an improved quality digital presentation is available for the client and, consequently, when a viewer signals that a particular type of information is not desired, that particular type of information is not transmitted to the client, which thereby reduces the streaming constraints on a video streaming service, and improved quality digital media information may be sent to any client using the freed-up portion of the bandwidth previously allocated to the signaling client. | 07-30-2009 |
20090190611 | FLOW CONTROL IN A NETWORK DEVICE - A network device includes output rate control logic having variable bandwidth and a response time constant that increases according to an amount of time that an input rate of data to the network device is evaluated by the control logic. | 07-30-2009 |
20090138601 | SWITCHED STREAM SERVER ARCHITECTURE - A method for allocating content requests to a server pool includes directing a stream requesting a novel title to one of a least-busy server in a server pool and a least-miss-traffic server in the server pool; setting the server to which the novel title was directed to the requested title's preferred server; directing a stream requesting a familiar title to the title's preferred server; and directing a stream requesting a crowded title to one of a least-busy server and the least-miss-traffic server. | 05-28-2009 |
20090070836 | SYSTEM TO PROVIDE INDEX AND METADATA FOR CONTENT ON DEMAND - A content on demand system includes logic to compose information about multiple audio and/or video streams into an audio and/or video stream format, and logic to communicate the information about multiple audio and/or video streams to a plurality of set top boxes. | 03-12-2009 |
20090067444 | Virtual networks in a communication system architecture - A method may include assigning to one or more I/O channels masks of message types that may pass through the channels, and when a message is sent or received, assigning to the message a channel having a mask that matches a type of the message. | 03-12-2009 |
20090052910 | Automatic dual receiver in a multi-wavelength fiber optic system - An optical-to-electrical converter may include and/or involve a splitter to separate one or more narrowcast signals from a broadcast signal, at least one broadcast signal receiver to receive the broadcast signal separated from one or more narrowcast signals, at least one narrowcast signal receiver to receive the narrowcast signal separated from the broadcast signal, the narrowcast receiver including an attenuator and a filter, and a controller including logic to dynamically monitor and adjust the attenuator to maintain separation between the broadcast and narrowcast signals. | 02-26-2009 |
20090043967 | Caching of information according to popularity - A system includes logic to cache at least one block in at least one cache if the block has a popularity that compares favorably to the popularity of other blocks in the cache, where the popularity of the block is determined by reads of the block from persistent storage and reads of the block from the cache. | 02-12-2009 |
20080205882 | Extended range for CWDM optical transport - A optical transmission system includes light sources generating light of at least two wavelengths, where any two adjacent wavelengths are separated by less than 10 nm. The wavelengths fall within the zero dispersion zone of an optical fiber, and may be shifted by 1 nm or less to reduce crosstalk effects. | 08-28-2008 |
