PURPOSE:To reduce the packet transmission time by allowing a sender side terminal equipment to send a packet comprising compressed communication information and control information and allowing a receiver side terminal equipment to receive only a packet addressed to itself and decoding the communication information. CONSTITUTION:A CPU 9 stores communication data to a RAM 11 and stores control data to a ROM 10. Data from the RAM 11 are compressed by a compression section 3 and combined with data from the ROM 10 at a combined section 4 and a packet is sent to a transmission line 2 from a transmission section 5. A reception section 6 of other terminal equipment on the transmission line 2 receives a packet only when an address included in the control data is addressed to itself, a separating section 7 separater the data and sends the control data to the CPU 9 and the communication data to a decoding section 8. The decoding section 8 decodes the compressed data and sends the result to the CPU 9 and the CPU 9 applies decoding processing to the control data and the communication data. Thus, the packet transmission time is reduced and the transmission efficiency is improved.
