摘要

According to the present invention, a digital system and a method for processing a service data in the digital system are disclosed. The digital system which processes data between a plurality of digital devices according to an embodiment of the present invention comprises: clients for transmitting reference data to a standard digital device; and a standard digital device which transmits map data, written for the clients′locations based on the reference data, to the clients. A first client of the clients transmits and receives data to at least one target client based on the map data received.
