Reception apparatus, reception method, demodulation apparatus, demodulation method, and program

A reception method for use with a reception apparatus, said reception method comprising:

• causing said reception apparatus to receive a signal modulated by a predetermined system defined by a predetermined standard;
• causing said reception apparatus to decode transmission parameters included in the received signal;
• causing said reception apparatus to acquire from among sequentially decoded transmission parameters the parameters used in a demodulation process performed on said received signal;
• and
• if the acquired transmission parameters used in the demodulation process on said received signal are different from the sequentially decoded transmission parameters, then causing said reception apparatus to control the demodulation process on said received signal based on newly decoded transmission parameters.

A non-transitory computer readable medium having stored thereon a program for use with a computer, wherein said program, when executed by the computer, controls the computer as follows:

• causing said computer to function as a reception section receiving a signal modulated by a predetermined system defined by a predetermined standard;
• causing said computer to function as a decoding section decoding transmission parameters included in the received signal;
• causing said computer to function as an acquisition section acquiring from among sequentially decoded transmission parameters the parameters used in a demodulation process performed on said received signal;
• and
• if the acquired transmission parameters used in the demodulation process on said received signal are different from the sequentially decoded transmission parameters, then causing said computer to function as a control section controlling the demodulation process on said received signal based on newly decoded transmission parameters.

A demodulation apparatus comprising:

• a decoding section configured to decode transmission parameters included in a received signal modulated by a predetermined system defined by a predetermined standard;
• an acquisition section configured to acquire from among sequentially decoded transmission parameters the parameters used in a demodulation process performed on said received signal;
• and
• a control section configured such that if the acquired transmission parameters used in the demodulation process on said received signal are different from the sequentially decoded transmission parameters, then said control section controls the demodulation process on said received signal based on newly decoded transmission parameters.
