Document Type and Number:
Japanese Patent JPH0771121
Kind Code:
B2
Abstract:
PURPOSE:To prevent the drop-out of data in the lump corresponding to packet length even if packet abolition takes place by providing a block sequence restoration information adding section and a block sequence restoration section or the like. CONSTITUTION:An analog signal inputted from an analog input terminal 1 is converted into a digital signal by a coder 2, formed into a packet via a packet forming section 3 and a block division section 4 and each packet is split into four packets and sent. Then each block is replaced among four packets by an inter-packet block replacement section 5 and sent to the block sequence restoration information adding section 6 in the order of replacement and sent to a transmission line 7 as a packet with restored information. In case of reception, the packet with restored information is inputted to a block sequence restoration section 9 via the line 8, the sequence of the block is restored and sent to a decoder 10, where the signal is converted into an analog signal and outputted. Thus, the drop-out of digital signals by the length of packet in the lump is prevented.
