Abstract

A receiving apparatus for receiving a radio signal through an antenna. The radio signal is transmitted by a moving transmitting apparatus and has a frame configuration which includes at least a main information portion that includes information main part based on an image signal and an added portion that includes synchronization information and parameter information specific to the transmitting apparatus. The receiving apparatus includes a detecting unit that is configured to detect, from the received radio signal, an arrangement position of the parameter information in a frame configuration in which an error-correcting code is added immediately after the parameter information to be transmitted in a predetermined arrangement position of the frame configuration. A parameter information error correcting unit is configured to perform error correction on the parameter information with the error-correcting code that is added immediately after the detected arrangement position of the parameter information. An image processing unit is configured to perform image processing on the image signal of the main information portion using the corrected parameter information.
