Abstract:
A centralized interactive TV recording and reproduction system linking several “Quality of Service” (QoS) reproduction and control units (such as television and audio reproduction receivers), as well as high bandwidth non-QoS legacy devices such as PCs, via a Home Area Network (HAN) to a centralized media server, has novel traffic control to prevent non-QoS devices from establishing and maintaining high-bandwidth network connections during the real-time transmission of media (video and/or audio) information from the media server to the QoS devices. In the preferred embodiment, the media server also contains a gateway device for connecting the HAN to a Wide Area Network, Metropolitan Area Network, and/or the Internet, and the media server also receives video and audio signals from sources such as cable, satellite, terrestrial broadcast, etc. The media server also contains a network router. All traffic from non-QoS devices is routed through the media server, and the media server limits the delivery of packets sent from source non-QoS devices to destination non-QoS devices. As a further refinement to prevent interruptions in real-time transmissions of video and audio information to QoS devices, the information can be buffered at the QoS device level.
Abstract:
A Medium Access Control protocol software architecture which comprises a microcode component providing the protocol implementation level functions and an engine component providing hardware level functions. The Medium Access Control protocol and method for use in a network system allows for centralized management of all MAC-level services by a master device. The Medium Access Control protocol provides an improved protocol message throughput via the sequence retransmission request protocol scheme. The Medium Access Control protocol provides a reduced data transmission latency and provides dynamic allocation of data slots within a Time Division Multiple Access frame definition. The Medium Access Control protocol also provides a set of failure management functions and power control support.
Abstract:
A set top terminal includes a tuner for receiving SDV programs over a content delivery system, an SDV module for coordinating SDV sessions in cooperation with an SDV manager associated with the content delivery system, and a DVR module for coordinating storage and playback of SDV programs received over the content delivery system. The SDV module is configured to transmit a message over the content delivery system substantially in advance of a time at which an upcoming SDV program is scheduled to be recorded by the DVR module. The message specifies when the upcoming SDV program has been scheduled for recording. A processor operationally associated with the tuner, the SDV module and the DVR module.
Abstract:
A device is operable to determine location of a packet-switched device, and the location is used to provide location-based services for the packet-switched device. The device includes an interface receiving a message. The message includes a tag inserted by an access point between the packet-switched device and the device. A database stores a plurality of tags and a location for each tag. The device parses the received message to identify the tag, and performs a lookup on the database using the tag to determine a corresponding location for the tag. This location is an estimation of a location of the packet-switched device, and the location is operable to be used to provide a location-based service for the packet-switched device.
Abstract:
A system and a method for alerting a Digital Video Recorder (DVR) viewer as to content that meets a predefined criteria of the viewer embedded within a real-time internet web feed and allowing the viewer to elect to view and/or record detected content that meets such criteria while viewing other content.
Abstract:
A content-carrying device, such as, for example, a sheet of photographic paper having a photographic image content printed on it, has a key device secured to it that is programmed with information that associates the content-carrying device with content that is related to the content printed on the content-carrying device. A recipient of the content-carrying device may use a key reader to read the information programmed into the key device to access this other related content, which may be stored in electronic form on a storage device at a location designated by the key information.
Abstract:
A reliable Medium Access Control layer protocol and method employing centralized management of communication in a Time Division Multiple Access network architecture. The Medium Access Control layer protocol implements Quality of Service guaranties to the layers of the Open Systems Interconnection reference model above the Medium Access Control layer by providing guaranteed bandwidth links within the bandwidth range specified by those layers. The Medium Access Control layer protocol further provides variable data slot requisition, variable data slot allocation, dynamic data slot reallocation, and data slot deallocation.
Abstract:
A method and apparatus for generating a baseband signal from a data pulse to approximate a filter transfer function is disclosed. The method comprises generating the data pulse, generating a plurality of delayed short pulses from the data pulse, and generating an output baseband signal from the of delayed pulses. The apparatus for generating a baseband signal from a data pulse to approximate a filter transfer function, comprises an input node coupled to the data pulse, an output node, a pull-up circuit coupled to said output node which generates positive going excursions of the baseband signal, and a pull-down circuit coupled to said output node which generates negative going excursions of the baseband signal.
Abstract:
A system [100] includes an audio reception device [105] to receive audio from a person speaking and convert the audio to a text format. An intelligent agent [110] receives the text format and detects at least one key term in the text format based on predetermined criteria. A logic engine [115] compares the at least one key term with a listener knowledge base [125] corresponding to a listener to determine context information corresponding to the at least one key term. A search device [135] searches for multimedia content corresponding to the context information. A communication device [150] communicates display content comprising at least one of: the multimedia content, and a link to the multimedia content to an electronic display device [155] adapted to display the display content.
Abstract:
A method of collaborative transcoding includes discovering capabilities of devices within a network; exchanging information about content stored within the network; anticipating a request for a content item in a target format; identifying a location of the content item by referencing the information about content stored within the network; and, if the content item is not in the target format, selecting a the device within the network to transcode the content into the target format. A system for collaborative transcoding includes a network, the network comprising a first networked device and at least one other networked device, the first networked device receiving a request for a content item in a target format; a shared content history; the shared content history comprising a list of content available on the network, the first networked device searching the shared content history to determine if another networked device can provide the content item; a capability list comprising a native format and transcoding capabilities of the networked devices, the first networked device searching the capability list to determine if any the networked device is configured to transcode the content item from a source format to a target format.
