A signal processing method for processing a signal received by a receiver device includes: performing a first correlation calculation on the received signal to obtain a first calculation result; performing carrier frequency offset estimation and compensation on the received signal to obtain a first compensated signal; performing a second correlation calculation on the first compensated signal to obtain a second calculation result; performing carrier frequency offset compensation on the first compensated signal to obtain a second compensated signal; determining whether at least one phase of the second compensated signal is correct; and determining whether at least one decoding result of the second compensated signal is correct. The received signal is determined not a signal conforming to a predetermined standard when the at least one phase of the second compensated signal or the at least one decoding result of the second compensated signal is determined incorrect.

Disclosed herein are systems and methods for performing DC offset correction of a video signal received over an AC-coupled video link. In one aspect, a transmitter is configured to compute, and provide to a receiver, metadata indicative of a statistical characteristic (e.g., an average or a sum of values) for a group of active pixels of a video signal acquired by a camera. The receiver is configured to compute an analogous statistical characteristic on the video signal received over an AC-coupled video link, and to perform DC offset correction by modifying one or more values of the received video signal based on a comparison of the statistical characteristic computed by the receiver and the one computed by the transmitter and indicated by the received metadata.

An HDMI source determines whether or not an HDMI sink can receive a sub-signal based on VSDB of E-EDID. When the HDMI sink can receive the sub-signal, the HDMI source adds a sub-signal to pixel data of a main image composed of pixel data whose number of bits is smaller than that of transmission pixel data transmitted by a transmitter, thereby constructing transmission pixel data. This data is transmitted by the transmitter through TMDS channels #0 to #2. Furthermore, the HDMI source transmits a general control packet containing sub-signal information indicating whether or not the sub-signal is contained in the transmission pixel data in the control period of a vertical blanking period. The present invention can be applied to, for example, HDMI.
