On this basis, it is decided (S50; S170) by the load control device, whether said subscriber terminal is to be associated with another one of said plurality of access points.

Provided are apparatuses and methods for padding a series of real-time service time-slice bursts with related non-real-time service data in a digital broadcast transmission system. Real-time services (e.g., streaming video) are formed into a series of bursts or slots as a single frame. Available capacity within each slot of the frame is filled using related non-real-time service data (e.g., a file download). Receivers may receive individual bursts from within the frame and / or may receive the entire frame in order to receive the related non-real-time service data.

The invention relates to data networks, and to nodes making up parts of data networks, arranged to derive information relating to the characterisation of paths taken by data travelling between nodes in the networks.

Provided are systems and methods for minimizing co-channel interference on-board a satellite. An up-link signal received by the satellite is post-compensated, where the up-link signal includes a desired signal transmitted by a first transmitter and an interfering signal transmitted by a second transmitter. The post-compensating includes identifying the interfering signal based on post-compensation parameters. In addition, a down-link signal to be transmitted from the satellite to a receiver is pre-compensated. The pre-compensation process includes determining gain relations between a gain of a first satellite antenna which transmits the down-link in a direction of the receiver and a gain of a second satellite antenna which transmits an interfering signal in the direction of the receiver, sampling and scaling interfering signals at the satellite based on the gain relations, and estimating a co-channel down-link interference component that the down-link signal is expected to experience on a path to the receiver.

Rather than dropping packets, the invention throttles the rate that audio packets are output from a voice gateway by increasing the VoIP packet size. An encoder in the voice gateway encodes audio signals into audio packets. A processor in the voice gateway then switches the audio packets to the IP network. The invention throttles the rate that these VoIP packets are switched from the voice gateway by varying the number of samples of the incoming audio signals that are encoded into each packet payload. By increasing the packet payload size in the VoIP packets, the voice gateway can switch the same amount of audio data in fewer VoIP packets. Producing fewer VoIP packets increases the available capacity of the voice gateway for processing audio signals for more calls. In other words, encoding more audio data into each VoIP packet keeps the voice gateway from having to drop packets. If capacity in the voice gateway increases (the number of incoming calls decreases), the voice gateway can resume generating VoIP packets at the original packet size.

A loop protection mechanism including dynamically determining a link connecting two adjacent nodes of a loop in a communication network in accordance with a predefined criterion, and reconfiguring the loop so that the loop is broken at the determined link which is an optimal link in terms of the predefined criterion.

In order to enable a more efficient use of an available transmission capacity, a transmitting device (10) assigns at least one identifier in common to at least two receiving devices (20, 30, 40). Further, it signals the at least one identifier to each of the receiving devices. A receiving device (20) receives and registers such a common identifier. Thereafter, the transmitting device announces a respective transmission of data packets for at least one of the receiving devices on a transmission channel by signaling the at least one common identifier. The receiving device (20) receives and detects such an identifier, which is used by the transmitting device (10) for announcing a transmission of data packets. The receiving device then extracts data packets for the receiving device from data packets on the transmission channel announced by the detected identifier.

A multi-format digital video production system enables a user to process an input video program to produce an output version of the program in a final format which may have a different frame rate, pixel dimensions, or both. An internal production format of 24 fps is preferably chosen to provide the greatest compatibility with existing and planned formats associated with HDTV standard 4:3 or widescreen 16:9 high-definition television, and film. Images are re-sized horizontally and vertically by pixel interpolation, thereby producing larger or smaller image dimensions so as to fill the particular needs of individual applications. Frame rates are adapted by inter-frame interpolation or by traditional schemes, including “3:2 pull-down” for 24-to-30 fps conversions. Simple speed-up (for 24-to-25 conversions) or slow-down (for 25-to-24 conversions) for playback, or by manipulating the frame rate itself using a program storage facility with asynchronous reading and writing capabilities. The step of converting the signal to a HDTV format is preferably performed using a modified upconversion process for wideband signals (utilizing a higher sampling clock frequency) and a resizing to HDTV format frame dimensions in pixels.

A method and system identifies a data file for transfer to a user. The invention also detects the movement of the user device from which the data file transfer was made and calculates a projected path for movement of the user device. Based on the projected path of movement, the sections of the requested data file are transferred in parallel to node areas where the user device is projected to move according to the projected path. As the user enters a node area, the section of the data file downloaded to that node area is locally transferred to the user device and thereby substantially reducing download time of a large data file.
