Beschreibung
Zusammenfassung:	The present invention provides a transmission line encoding/decoding system wherein encoding is effected in such a manner that an overhead bit which indicates whether or not a slot, all the bits of which are "0" bits (hereinafter referred to as an all-"0" slot), is present among a plurality of slots constituting in combination one block and is set in a predetermined slot in the block, and if there are all-"0" slots, a slot information bit which indicates the slot position of at least one all-"0" slot is set and at least one all-"0" slot the position of which is indicated by the slot information bit is deleted, and wherein decoding is effected in such a manner that whether or not an all-"0" slot was present in one block before the encoding process is judged on the basis of an overhead bit set at a predetermined position in the block of the received data, and if it is judged that there was an all-"0" slot, the slot information bit indicating the slot position of the all-"0" slot that has been set in the received block is removed and an all-"0" slot is reconstructed at the position indicated by the slot information bit.
