A method of transmitting image data from a first node to a second node during a communication event, wherein the second node comprises a display for displaying image data at the second node, includes receiving at the first node, information indicating at least one display characteristic with which image data received at the second node will be displayed on the display; inputting image data at the first node; determining a processing step to be applied to the inputted image data to generate adapted image data, such that at least one characteristic of the adapted image data is optimized for the at least one display characteristic; applying the processing step to generate the adapted image data; and transmitting the adapted image data to the second terminal.

Method of transmitting data in a communication system

A method of controlling communication quality between one node and at least one other node in a packet switched communication system, the method comprising the steps of detecting at one of said nodes a condition that indicates that communication quality is below an acceptable threshold, automatically generating instructions based on the detected condition for a user of the at least one node, said instructions intended to provide a remedy to improve the communication quality, and receiving input from a user of the at least one node responsive to the instructions to implement the remedy and thereby improve the communication quality.

User interface

A terminal comprises a plurality of hardware I/O units, including a wireless transceiver having a powered-up state in which at least one of a transmit path and a receive path is enabled at the expense of higher power consumption and a powered-down state in which the at least one path is disabled in favor of lower power consumption; a processing apparatus; and a storage medium coupled to the processing apparatus and storing at least a first and a second application, an operating system, a communication protocol layer and a driver layer arranged to be executed on the processing apparatus. The operating system is arranged to arbitrate access by the plurality of applications to the hardware I/O units via the driver layer, including access to the wireless transceiver via the communication protocol layer and driver layer. The second application comprises a wireless traffic scheduler configured to coordinate traffic associated with the second application to be communicated via the wireless transceiver during a same continuous phase of the powered-up state as traffic associated with the first application.

Saving power in a wireless communication device

According to an embodiment, a mobile device includes wireless access circuitry configured to access a wireless communication network; a processor for executing a communication client application to conduct a packet-based call with a remote device via a channel established over the wireless communication network, the communication client application configured to monitor at least one network parameter; a hardware processing module selectively operable to implement a processing function; a software processing module selectively executable to implement said processing function; and a selection mechanism for supplying the call to one of the hardware processing module and software processing module based on the at least one monitored network parameter.

Signal processing

A method and product for controlling a rate of transmission from a first, transmitting node to a second, recipient node. The method comprises: transmitting a stream from the first node to the second node over a first network route; transmitting further data from the first node to a third node over a second network route substantially overlapping with the first network route; receiving feedback at the first node from the third node regarding transmission of the further data to the third node over the second network route; and based on the feedback from the third node, controlling a rate of transmission of the stream to the second node over the first network route. The third node may not be a recipient of said stream. The rate of transmission may be controlled without feedback from the second node. The further data may be formed of dummy data.

Data rate control mechanism

A method of controlling quality of video data transmitted from a first user terminal to at least one other user terminal in a communication system includes detecting at said first user terminal a condition that indicates that the quality of the video data is below an acceptable threshold; automatically generating instructions based on the detected condition for a user of the first user terminal, said instructions intended to provide a humanly implementable remedy to improve the quality of the video data; outputting the instructions to the user in a humanly comprehensible form; and receiving an input from a user of the first user terminal responsive to the instructions to implement the remedy and thereby improve the quality of the video data.

A communication system, method and program, the system comprising: one or more wireless access nodes of a first communication service provider and at least one server associated with a second communication service provider, interconnected via a packet-based network; and a wireless user terminal operable to establish a session with one of the wireless access nodes of the first communication service provider, the wireless user terminal is installed with an application of the second communication service provider. The application is configured so as to: in event of failure to establish a session via one of the wireless access nodes of the first communication service provider, store information regarding the failed session at the wireless user terminal; and in event of subsequent access to the packet-based network, transmit the information regarding the failed session to the server associated with the second communication service provider over the packet-based network.
