Electronic device and associated signal processing method

Abstract

An electronic device includes a decoder circuit, an image processing circuit, a detection circuit, a transmission interval determination circuit, an auxiliary data extraction circuit, and an encoder circuit. The decoder circuit decodes an input signal to generate the decoded signal. The image processing circuit performs image processing on the decoded signal to generate processed image data. The detection circuit detects timing of an active display area and a vertical synchronization signal in the processed image data to generate a detection result. The transmission interval determination circuit determines a transmission interval of the processed image data according to the detection result. The auxiliary data extraction circuit extracts auxiliary data from the decoded signal. The encoder circuit places the auxiliary data in the transmission interval of the processed image data, and performs encoding to generate an output signal.
