Title: Method of power control in an optical communication system
IPC: H04B10/296
Filed: 2000-09-13
Abstract: An optical communication system (10) and a method of operating the system (10) to reduce non-linear phenomena in optical fibre waveguides (60, 70) included within the system (10) are discribed. The communication system (10) comprises a plurality of nodes (20, 40) coupled together by optical fibre waveguides (60, 70) for guiding communication traffic bearing radiation between the nodes. The system (10) further comprises: an attenuator and associated optical amplifier (110, 120) for regulating radiation power of the communication bearing radiation at the first node to generate corresponding output radiation; an a coupler (130) for emitting the output radiation into the optical fibre waveguide (60) to propagate to a second node (70). A power monitor (210) is provided for measuring radiation power of the output radiation received at the second node after it has been conveyed through the waveguiding means and for generating corresponding power indicative data. A power controller (160) for receiving the power indicative data is operable to regulate the radiation power measured at the second node to a predetermined level by generating corresponding error data and communication the error data to the attenuator (110) for controlling the attenuator (110) so that the radiation power measured at the second node is stabilized substantially at the predetermined level at which optical non-linearities are reduced to less than a predetermined threshold in the optical fibre waveguide (60).

Title: An apparatus and method for synchronising internet and television services
IPC: H04N7/24
Filed: 2001-03-06
Abstract: A system for transmitting data by a plurality of routes where there is a possibility of a difference in timing of reception of data via different routes, e.g because of different transmission speeds, in which information indicative of the characteristics of at least one route is used to adjust the timing of transmission of data over at least one of the routes so as to synchronise the time of reception of data. In particular, there is disclosed a system for synchronising reception of an internet service in an internet transmission with an audio/video broadcast transmission, including an adaptive scheduler for determining network characteristics for the internet transmission and the audio/video broadcast transmission. The system provides synchronisation triggers for respective events of the internet service at timings relative to the broadcast transmission according to the determined network characteristics.

Patent GB-0328249-D0 (GB)
Title: Data reception in a multi-function receiving device
IPC: H04M1/72403
Filed: 2003-12-05
Abstract: A data receiving device ( 2 a) is arranged to run a media guide application through which a user may access a service provided over broadcast network ( 3 ). Should reception of the service be interrupted, for example, by an incoming telephone call over telecommunications network ( 4 ), the data receiving device ( 2 a) operates in a first resource saving mode where data is received by receiver ( 11 ) but neither processed nor output. The received data may be stored for later output or simply discarded. The service can then be resumed, with minimal delay, by restarting processing and outputting of received data, as it is not necessary to reactivate or resynchronise the receiver ( 11 ). After operating in said first resource saving mode for a predetermined time period, the receiver ( 11 ) may be deactivated in order to further save power. Applications used in receiving, processing and/or outputting the received data, may be closed down following the expiry of one or more further predetermined time periods.

Title: Multi-bus microcomputer system with bus arbitration
IPC: G06F9/44
Filed: 1989-03-03
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.
