Abstract:
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium that provides an enhanced synchronization framework. One of the methods includes a primary and a second device that receive configuration information which identifies one or more actions to be performed by the secondary device when it receives specified pulses of a sequence of pulses from the primary device. The primary device transmits a sequence of pulses. The primary and the secondary device receive a particular pulse from the sequence of pulses. The secondary device determines whether the particular pulse satisfies one or more predetermined criteria and generates an instruction based on the determination.
Abstract:
A diversity receiver synchronizes and mixes multiple input signals. In one embodiment, the receiver demodulates the multiple input signals prior to synchronizing, converts the demodulated multiple input signals from analog signals to digital signals, synchronizes the demodulated digital signals, converts the synchronized demodulated digital signals to analog signals and mixes the synchronized demodulated analog signals based on a characteristic of the input signals existing prior to the demodulating.
Abstract:
A programmable image transform system has a programmable addressing and arithmetic blocks (410/420). In the programmable addressing block (410), an input address generator (442) has an input addressing microsequencer and an input addressing memory that stores an input addressing procedure. The microsequencer executes the input addressing procedure to generate addresses from which to request image data. In the programmable arithmetic block (420), an arithmetic block memory stores an image processing procedure and a microsequencer executes the image processing procedure using the image data to generate transformed image data.
Abstract:
A digital switching signal sequence is suggested, this switching signal sequence being realized as a previously digitized, highpass filtered white noise signal of a predetermined length T, with a highpass cut-off frequency which lies above the frequency where the loudness threshold characteristic in silence of the human hearing has its highest sensitivity, if possible (Fig. 5). The switching signal sequence is employed for switching purposes (206), e.g. for switching between two information signals (201, 207). Fig. 2
Abstract:
The invention provides a processing system, comprising a video signal processing unit for processing a video signal, the video signal processing entailing a video signal processing delay, and video delay control for controlling said video signal processing unit in dependence on a maximum allowed value for the video signal processing delay. The invention also provides an audio-video signal source, comprising an output for sending a video signal to a video signal processing unit, and an output for communicating to the video signal processing unit a maximum allowed value for a video signal processing delay entailed by video signal processing in the video signal processing unit. The invention further provides an audio signal processing unit, comprising an audio signal processing unit, said audio signal processing entailing an audio signal processing delay not exceeding a maximum audio delay, and an output for communicating to the video signal processing unit a maximum allowed value for a video signal processing delay entailed by video signal processing in the video signal processing unit, the maximum allowed value for the video signal processing delay depending on the maximum audio delay.
