Transmission apparatus and control data processing method and program

A control-data processing method comprising:

• recording control data, included in a frame received from an apparatus, to a memory in association with state information indicating a state of the control data in the apparatus;
• changing, when the recording of the control data is completed, the state information to information indicating that the memory of the control data is completed;
• executing determination processing for determining, when the state information is changed, whether or not the control data stored in the memory is to be rewritten, and to execute, upon determining that the control data is to be rewritten, rewriting processing to rewrite the control data stored in the memory;
• changing, when the determination processing or the rewriting processing is completed, the state information to information indicating that the determination processing or the rewriting processing is completed;
• and
• starting reading of the control data stored in the memory, when the state information is changed.

A computer-readable recording medium encoded with a control-data processing program containing instructions executable on a computer, the program causing the computer to execute:

• recording control data, included in a frame received from outside an apparatus, to a memory in association with state information indicating a state of the control data in the apparatus;
• changing, when the recording of the control data is completed, the state information to information indicating that the recording of the control data is completed;
• determining, when the state information is changed to information indicating that the recording of the control data is completed, whether or not the control data stored in the memory is to be rewritten;
• rewriting the control data stored in the memory, upon determining that the control data is rewritten;
• changing, when the control data is rewritten, the state information to information indicating that the rewriting of the control data is completed;
• and
• reading, when the state information is changed to information indicating that the rewriting of the control data is completed, the control data stored in the memory.
