Abstract
A CATV data transmission method in which data is transmitted to terminal units having their own addresses by addressing. Each terminal unit has a memory storing its own address and a plurality of group addresses, each being used for collectively transmitting data to the terminal units in the respective group. When addressed by the data transmission side, the terminal unit performs comparison with its own address and comparison with the group addresses successively. When coincidence is obtained in the comparison, data is received from the terminal unit.
