摘要： A time synchronization method includes: after sending a synchronization message to the opposite end, sending a following message where an ending time for sending the synchronization message is recorded; receiving a delay request message sent by the opposite end, and sending a delay response message where the initial time for receiving the delay request message is recorded; receiving the synchronization message and the following message, and recording the initial time for receiving the synchronization message and the ending time recorded in the following message for sending the synchronization message; sending a delay request message, and recording an ending time for sending the delay request message; receiving a delay response message, and recording an initial time recorded in the delay response message for the opposite end to receive the delay request message; calculating the time offset value between the two ends, and completing time synchronization.

摘要： Embodiments provide an area, cost, and power efficient multi-service transceiver architecture. The multi-service transceiver architecture simplifies receiver/transmitter front ends needed for a multi-service architecture, by replacing significant portions of multiple receiver and/or transmitter front ends with a single ADC and/or DAC, respectively. In embodiments, a plurality of received service contents are combined into one composite analog/RF signal and applied to an ADC. The ADC converts the composite signal into a composite multi-service digital signal. Digital techniques are then used to separate the plurality of service contents into a plurality of respective digital streams that each can be independently demodulated. Similarly, in the transmit direction, a plurality of digital streams, including a plurality of service contents, are combined into one composite digital signal. The composite digital signal is applied to a DAC to generate a composite multi-service analog/RF signal for subsequent transmission over a coaxial cable or wirelessly via an antenna.

摘要： Apparatus and methods relating to synchronization of communication equipment are disclosed. Synchronization information received from a bonded communication link can be used to synchronize local and/or remote communication equipment, such as femtocell sites coupled to nodes in a ring network. This may involve isolating a frequency reference signal from a DSL (Digital Subscriber Line) communication link which is a constituent link of a bonded communication link, for example. In a ring network, received synchronization information could be used in synchronizing a locally connected installation of communication equipment, and passed for transmission in the ring network for synchronizing other communication equipment. Such dropping and passing of an analog frequency reference signal could be applied in networks having other topologies as well. At least some embodiments of the invention are applicable to optical links. One or more dedicated wavelengths of an optical link could be used to transfer a frequency reference signal, for example. Other functions, such as quality monitoring, quality reporting, and/or predictive traffic forwarding may be provided in some embodiments.

摘要： Fast channel changing in digital-television-based entertainment networks can be implemented, for example, by electing to tune to channels at opportune tuning times. In an exemplary implementation, a method includes: receiving a channel change request that indicates a requested new channel from a client device; preparing a broadcast video data stream of the requested new channel that is offset in time behind a current broadcast time for broadcast video data of the requested new channel; and streaming the broadcast video data stream responsive to the channel change request. In another exemplary implementation, a system includes: a storage device that retains broadcast video data for multiple channels; a video data extractor that accesses the retained broadcast video data and retrieves an intra frame of broadcast video data that is in the past for a requested channel; and a video data distributor that transmits the retrieved intra frame of broadcast video data.

摘要： A method of selecting a suitable service for the delivery of a communication across an integrated network is disclosed. Before now, users had to select the service that best suited their needs at the time of each delivery. By providing a computer programmed to act as a purchasing agent with data indicating the desirability of stability in the network service (that data representing the price the user is prepared to pay for stability) an automatic selection of the service to be provided to the communication is enabled. An embodiment is described in which different degrees of stability are given to different content file deliveries in dependence on the importance attached to the recipient by a content provider. The invention could equally be used to provide an appropriate services for many different types of network traffic.

摘要： A method for transmitting policy information between network equipment, extending protocol types of messages in layer-2, layer-3 or a higher application layer between an IP-uplink broadband user access equipment and a BRAS so as to construct a PITP to bear policy information; a PITP message includes a policy information transmission type field, an operation type field and a policy information content field, and different types of policy information are distinguished by the policy information transmission type field; transmission of the policy information is implemented through a point-to-point means or a broadcast means in layer-2, a unicast or a multicast in layer-3 or a higher application layer. The present invention implements policy information transmission, prevents account intrusions and hacker attacks, makes it convenient for the broadband user access equipment to implement dynamic QoS policy adjustment in terms of different users and makes it easy for integrated managing the online equipment.
