Abstract: Described are techniques and systems for providing service account credentials to a media device. A remote control configured to control the media device may include a remote identifier, service account credentials, or both to the media device. The media device may acquire the service account credentials, and configure the media device to perform one or more operations using the service account credentials. As different remote controls associated with different service account credentials are used, the media device is reconfigured according to the inputs from those remote controls.

Abstract: User input is provided to an application resident on a data processing system by contacting a contact-sensitive surface of a user input device such as a touch screen with an implement configured to produce a contact point configuration including at least one contact point. The contact point configuration is identified, and a user input mode is identified based on the identified contact point configuration. The at least one contact point is then processed in the application based on the identified user input mode. The contact-sensitive surface may be contacted with an implement having first and second ends configured to produce respective first and second contact point configurations when placed against the contact-sensitive surface.

Abstract: A speakerphone having echo suppression is provided. The speakerphone has an audio control system comprising a transmit path, a receive path, a pair of rectifiers for producing rectified signals indicative of the strength of the signals present on the receive path and the transmit path, respectively, and an analog-to-digital converter for generating digital samples of the rectified signals for further processing. The audio control system further includes a general use microprocessor. Samples of the rectified signals are taken periodically and processed to determine if the receive path or the transmit path should have control, or if the audio system should be in an idle state. If speech is detected on either channel, the samples are weighted depending on the current state of the audio system. The weighted samples are then analyzed to determine which path should have control.
