摘要:
A conference call is established in response to receiving a request 4 from a first communication terminal 3a. The request 4 preferably is an SMS or MMS and comprises one or more identifiers 5, 6, 7, e.g. telephone numbers, relating to a plurality of other communication terminals 3b-3d. A conference call server I allocates a conference call channel and an associated identifier, such as a telephone number. Messages 10a-10c alerting the conference participants are then sent to the other communication terminals 3a-3c, each message including the identifier associated with the conference call channel. Access to the conference call may be restricted to authorised users by compating identifiers, such as CLIs, of incoming callers to the identifiers provided in the request 4 and allowing access only if there is a correspondence or match. In the event that an incoming caller has withheld their CLI, or it is otherwise nondeterminable, access is refused and a message may be sent reminding conference participants who have yet to join the conference call not to withhold this information. Alternatively, the server calls the participants at the appropriate time.

摘要:
In a headset audio speech signals are picked up by the microphone, where they are digitally sampled before being encoded by a vocoder. The coded speech data is then provided to a CRC module, where error correction data is added before the resulting data is encrypted by an encryption module. The resulting encrypted data is transmitted using a Bluetooth radio interface, by which the headset is connected wirelessly to a mobile telephone. Received data is decrypted by a decryption module, error corrected by an error correction module and decoded by a decoder, with the resulting audio signals then being reproduced at a speaker. When a user wants to instigate a telephone call with another telephone, the headset is caused to send a control signal to the mobile telephone instructing it to enter a data mode. A data call is then set up and, once established, the CPU controls the setting up of a 128 bit encryption key which is subsequently used for communications between the headset and a corresponding device associated with the recipient of the call. Encryption and decryption are performed only at the headset. This provides increased security since even if the call can be intercepted, the interceptor will need to decrypt the signals before being able to reproduce the audio signals.

The invention is directed to efficient notification of the hearing impaired during emergencies. A message initiating agency and an administrator create an outbound message for delivery and further selects a number of campaign related parameters. A telecommunications interface module is provided that is capable of detecting the presence of a connected TTY device, and a connected TTY device logging system for recording in a database the occurrences of detection of a TTY devices associated with a particular telecommunications interface, or outbound message contact. The system delivers the campaign message to one or more telecommunications interfaces, delivers a TTY compatible message or a provides notification to said administrator of the detection of a connected TTY device, and records the incidence of failures to deliver the campaign message.

A mobile device and corresponding service provider are configured to provide a user of the mobile device with access to one or more instant messaging help entities, from the mobile device. The one or more instant messaging help entities may be associated with the corresponding service provider or with a service that is external to the corresponding service provider. In some cases, some of the one or more instant messaging help entities may be embedded as part of the mobile device or service, so that access to the one or more help entities may not be permanently terminated by the user. In some cases, the user may control access to some of the one or more instant messaging help entities, such as by adding or removing the access to the instant messaging help entities from a list of instant messaging entities.

摘要:
An interactive television system displays a television program having an associated channel. The system also displays an interactive television mode indicator if the displayed television program supports an interactive television mode. The interactive television mode is activated in response to a request from a viewer of the television program to activate the interactive television mode. The system updates a channel status list to indicate that the television program is being viewed in the interactive television mode. The system is also able to handle requests for activating an online television mode. When changing channels, the channel status list is used to restore a previously activated interactive television ii mode or online television mode for a particular television channel. Two different indicators may be displayed to indicate whether the television program supports an interactive television mode and/or an online television mode.

A method of creating an image difference overlay comprises identifying a loop of reference images of a subject and identifying a loop of data images of the subject. The loop of image data can be identified after an event, such as the administration of contrast agent to the subject. A reference loop image frame is compared to one or more data loop image frames and the reference loop frame is associated with a data loop image frame which closely resembles the data loop image frame. Each of the associated frames can then be processed and used to create an image difference overlay frame.
