One then generates for each field of the first type:—a first difference signal (D1 F1) representative of the difference between the field and the second-type field of the previous frame;—a second difference signal (D1 F2) representative of the difference between the field and the second-type field of the same frame; and—a third difference signal (D1 F3) representative of the difference between the field and the second-type field of the following frame. Then, in dependence of the values of said difference signals, a decision signal (wOFlag) is generated indicating an estimated temporal relationship of the field to the second-type field of the same frame.

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®.
