Claim Text:
1. A reception method comprising: receiving a signal in which a first symbol sequence and a second symbol sequence are multiplexed, the first symbol sequence and the second symbol sequence each including video information and each being a precoded signal transmitted from a different transmission system; decoding information regarding a modulation scheme and information regarding an error correction scheme that are included in the received signal; demodulating the received signal based on the decoded information regarding the modulation scheme to generate a demodulation symbol sequence; and performing error-correction decoding on the demodulation symbol sequence based on the decoded information regarding the error correction scheme to output a data sequence including video information, wherein the first symbol sequence and the second symbol sequence are each generated by applying a precoding matrix to a modulation symbol sequence, the precoding matrix being regularly switched between a plurality of precoding matrices for precoding, the modulation symbol sequence being generated by using a modulation scheme indicated by the decoded information regarding the modulation scheme, a first symbol included in the first symbol sequence is transmitted at a first frequency, a third symbol included in the first symbol sequence is transmitted at a third frequency adjacent to the first frequency in a frequency domain, a second symbol included in the second symbol sequence is transmitted at a second frequency, a fourth symbol included in the second symbol sequence is transmitted at a fourth frequency adjacent to the second frequency in the frequency domain, and in the case where the third transmission symbol is a data symbol,
