摘要： In a cable broadcasting system of the invention capable of setting output or stop of broadcasting-signals from tap output terminals of a tap device in response to a command signal transmitted by a center equipment, when demand for output setting for many tap devices occurs, output setting of the corresponding tap devices can be surely carried out without increasing the load on each power supply device for supplying the tap devices in each district with electricity. When demand for setting tap output of plural tap device occurs, a head-end controller reads output setting data for all the tap devices which are the objects of tap output setting and transmits command signals in order to tap devices at a rate of one tap device per each district covered by a power supply device. The interval of transmission of command signals to one district is controlled to be longer than or equal to the time Δtn necessary for the tap device to which a command signal was previously transmitted to finish tap output setting operation.

摘要： A distributed network data management system implementing centralized management control over the transfer of data files from data servers to remote client computer systems, where the data file transfers are performed in response to requests issued by the remote client computer systems. The distributed network data management system includes a control server system having a control file store coupleable through a communications network to a client computer system. The control server system can provide a predetermined control file to the client computer system in response to a request provided by the client computer system autonomously determined by the client computer system based on a prior provided control file. The control file includes an identification of data files and a set of data servers from which the data files can be requested for transfer to the client computer system. The identification of the data files can also specify a temporal distribution of the requests for the transfer of the data files among the set of data servers.

摘要： Aspects of the subject disclosure may include, for example, a method for providing redundancy in a video data stream. For every data frame of a plurality of data frames of video content, the method includes dividing the data frame into a plurality of data segments and copying a plurality of each of the plurality of data segments to the plurality of data frames in a data stream to provide redundancy for the data frame within the plurality of data frames in the data stream. The plurality of each of the plurality of data segments is distributed across the plurality of data frames to provide generate a plurality of redundancy-enhanced data frames that provide the redundancy over a protection interval associated with a network path. The method includes transmitting a data stream comprising the plurality of redundancy-enhanced data frames to a receiver via the network path. Other embodiments are disclosed.

摘要： A coupling device for use in a hybrid fiber coaxial (HFC) network may be configured to detect a control message and determine from the message a period for which a cable modem downstream is to be transmitting a desired transmission, disable an upstream path through it when there is only noise incident on the upstream path, and enable the upstream path during the period when a desired transmission from a cable modem downstream of the coupling device is incident on the upstream path. The coupling device may be a trunk amplifier, a distribution amplifier, or a splitter. The coupling device may comprise a single upstream interface coupled to a plurality of downstream interfaces. The enabling and/or disabling may be in response to a signal strength indicated by the SSI being below a threshold.

摘要： A system and method for providing non-guaranteed channels in a switched digital video network using multicast adaptive bitrate (ABR) streaming. In one implementation, upon receiving a request for a non-guaranteed channel is received from a subscriber station (e.g., a set-top box or STB), a bandwidth pipe modeling process is operative to model a bandwidth pipe corresponding to each edge QAM device configured to support non-guaranteed channels for selecting a particular edge QAM device that can best accommodate the requested non-guaranteed channel. Bitrates of MABR streams of existing channels of the selected edge QAM device may be adjusted in order to accommodate a particular MABR stream at chosen bitrate of the requested non-guaranteed channel. IGMP Join operations may be effectuated, as needed, to join MABR streams of the existing channels and the requested non-guaranteed channel to correct IGMP group(s). A channel change response message including one or more channel frequencies, if the change request is accommodated, may be transmitted to the requesting subscriber station.

摘要： The present disclosure describes a legacy converter for an audio distribution system that uses a local area network where the legacy converter converts a digital audio signal to and from an analog audio signal and provides an external bridge connection between the audio system and one or more legacy sources and one or more legacy control networks. The legacy converter includes a network controller where the network controller further includes an embedded controller with memory and which is programmed to function as a web server. In addition, the legacy converter includes a network interface, an audio format converter that includes one or more audio encoders to provide multiple conversions of different legacy audio inputs simultaneously, an analog to digital converter, a legacy controller, a legacy audio network interface that bridges the legacy sources, and, a legacy control network interface.
