Abstract:
Disclosed is an apparatus and method of power-saving and wake-up, which is not only used to reduce the power consumption of a system of electronic equipment, but also allow the system to immediately return to normal operation according to the requirement. The apparatus for power-saving and wake-up includes a first detector, a second detector, a decoder and a third detector. The method for power-saving and wake-up includes detecting a cable signal, a clock pair signal and a differential pair signal. When one of the detected signals is unusual, the system soon turns off the unusual channel power and implement the procedures for power saving and operates under the power saving mode, which can realize the effect of power saving and low power consumption. The method for power-saving and wake-up includes detecting the cable signal, the toggling and frequency of the clock signal and the synchronizing signals of the system.

The invention relates to a receiving device for an audio-video system. The receiving device comprises a connector, a video processing unit, an audio processing module, and a monitoring unit. The monitoring unit detects a status of an inputted signal received by the connector and controls the operation of at lease one of the video processing unit and the audio processing module in accordance with the detected result to avoid the audio-video system display abnormal image or play noise when the receiving device did not receive the inputted signal by accident.
Abstract:
An apparatus for processing an audio signal and method thereof applied to an audio playback system are disclosed. The apparatus comprises a decoder, an error-correcting circuit and an audio correcting module. The method for processing audio signals in accordance with the present invention decodes the audio signal to generate a decoded signal by the decoder. Then, the error-correcting circuit performs an error-correcting algorithm in the decoded signal to generate an error indication signal and an output audio signal. And the audio correcting module corrects the output audio signal to generate a corrected audio signal when the error indication signal indicates that the output audio signal has error.

An error correction circuit and method applicable to a DisplayPort receiver is disclosed. While decoding errors occur at a decoding stage, the invention actively adjusts settings of a physical layer by using an ANSI10B/8B decoder and performs data recovery by using a correcting unit that improves the reliability of input data.
Abstract:
The present invention provides an integrated circuit suitable for various packaging modes. This integrated circuit includes: a core circuit, a plurality of pads, and a selection circuit. The selection circuit is coupled between the core circuit and the pads for determining the connection state between the core circuit and the pads based on a control signal. When the control signal provides a first value, the core circuit and the pads will be in a first connection state, and the integrated circuit will be applied with a single-die package. However, when the control signal provides a second value, the core circuit and the pads will be in the second connection state, and the integrated circuit will be applied with a multi-die package.
Abstract:
A differential signal generating device includes a control circuit and a differential signal driver receiving a single-ended signal. The control circuit receives a source signal and generates a control signal corresponding to a first mode when the source signal conforms with a first pre-defined state, and corresponding to a second mode when the source signal conforms with a second pre-defined state. Variations of the source signal are related to signal content of the single-ended signal. The differential signal driver is coupled to the control unit for receiving the control signal therefrom. The differential signal driver outputs a differential signal output according to the single-ended signal when the control signal corresponds to the first mode. The differential signal driver outputs a non-differential signal output when the control signal corresponds to the second mode.
