Data tranmission and reception device and system, data transmission method and parameter setting method for data reception device

摘要

A data transmitting method comprising the steps of generating (15) parameter setting data for various items cf hardware, embedding (16) the parameter setting data into a control code and transmitting (18) that control code. The parameter setting data sets parameters for a plurality of hardware versions and includes parameter setting data common to at least first and second hardware versions, parameter setting data limited to a first hardware version, and parameter setting data limited to a second hardware version. Thus, the first version of hardware utilizes parameter setting data intended for it while the second version of hardware utilizes parameter setting data intended for it.
