Abstract: A transmission frame generating device includes a control information signal generator and a frame former. The control information signal generator generates a modulation method information signal indicating a modulation method of a data signal and an error correction method information signal indicating an error correction method of the data signal. The frame former forms the transmission frame by repeating and discretely arranging the same modulation method information signal on a first multiple of a plurality of subcarriers on a frequency axis and by repeating and discretely arranging the same error correction method information signal on a second multiple of the plurality of the subcarriers on the frequency axis.

Abstract: An image capturing apparatus includes an input unit, a detecting unit, and a controller. The input unit continuously inputs a signal sequence. The signal sequence includes values of multiple pixels and control information. The pixels constitute an image. The control information is embedded at multiple positions according to a rule. The detecting unit detects occurrence of an error on the basis of the inputted control information. The controller interrupts the input performed by the input unit when the detected error is based on the control information embedded in a first region of the image, and continues the input when the detected error is based on the control information embedded in a second region.
