COMMUNICATION SYSTEM AND COMMUNICATION UNIT

PROBLEM TO BE SOLVED: To provide a communication system with which a much larger amount of desired information only is acquired among a huge amount of received information with a simple operation. SOLUTION: When a receiver side 15 receives desired main information, a user operates an entry section 7 to designate the time of its reception. A recording section 4 records the main information to which the time zone information of a time zone corresponding to the designated time is added, in other words, only all the pieces of main information related to the desired main information among received pieces of main information. Thus, only all the pieces of the main information relating to the desired main information can selectively be recorded and acquired with a simple operation among a huge amount of the received main information. Since the information whose acquisition is desired is transmitted as the main information, the information amount and the information contents to be acquired are abundant.
