Abstract
Abstract A method for transmitting time-sharing multidata in which data series of a plurality of channels are time-sharing multiplexed to form a transmitting data series having the steps of adding an error detecting or error correcting redundant bit and a synchronizing redundant bit to an information bit of a predetermined number contained in the respective data series of said channels to form one transmitting unit, forming bit groups in a manner as to take each bit as one group which is corresponding to each other between the channels with respect to the information bit, the error detecting or error correcting redundant bit and the synchronizing redundant bit of said one transmitting unit of each of said channels, time-sharing multiplexing the data series so as to form one frame in which these bit groups are sequentially continued to each other and using a bit pattern of the bit groups in the synchronizing redundant bit as a frame synchronizing signal of the transmitting data series.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A method for transmitting time-sharing multidata in which data series of a plurality of channels are time-sharing multiplexed to form a transmitting data series, said method for transmitting time-sharing multidata comprising the steps of: adding an error detecting or error correcting redundant bit and a synchronizing redundant bit to an information bit of a predetermined number contained in the respective data series of said channels to form one transmitting unit; forming bit groups in a manner as to take each bit as one group which is corresponding to each other between the channels with respect to the information bit, the error detecting or error correcting redundant bit and the synchronizing redundant bit of said one transmitting unit of each of said channels; time-sharing multiplexing the data series so as to form one frame in which these bit groups are sequentially continued to each other; and using a bit pattern of the bit groups in said synchronizing redundant bit as a frame synchronizing signal of said transmitting data series.
Claim 2
Independent Claim
168 words
A method for transmitting time-sharing multidata in which data series of a plurality of channels are time-sharing multiplexed to form a transmitting data series, said method for transmitting time-sharing multidata comprising the steps of: adding an error detecting or error correcting redundant bit and a synchronizing redundant bit to an information bit of a predetermined number contained in the respective data series of said channels to form one transmitting unit; forming bit groups in a manner as to take each bit as one group which is corresponding to each other between the channels with respect to the information bit, the error detecting or error correcting redundant bit and the synchronizing redundant bit of said one transmitting unit of each of said channels; time-sharing multiplexing the data series so as to form one frame in which these bit groups are sequentially continued to each other; and using a bit pattern of the bit groups in said synchronizing redundant bit as a frame synchronizing signal of said transmitting data series.
Claim 3
Dependent Claim
123 words
A method for transmitting time-sharing multidata according to claim 1, wherein such a code arrangement in which an information bit of k I bits is arranged in a row direction and the information bit series is arranged in k 2 bit column direction to form an information bit of (klx k2) matrix and a vertical parity bit relative to the k 2 bit in said column direction and a parity bit based upon a BCH code relative to the respective k 1 bit of said row direction and said vertical parity bit are added to the information bit of (k 1 x k 2 )matrix and which can perform an error detection and error correction is used as said error correcting redundant bit.
Claim 4
Dependent Claim
54 words
A method for transmitting time-sharing multidata according to claim 2, wherein as a decoding of said code which can detect and correct the error, a method for performing the error detection and correction process based upon said BCH code, and the error detection and correction process based upon said vertical parity bit is employed.
Claim 5
Dependent Claim
72 words
A method for transmitting time-sharing multidata according to claim 1, wherein for said error correcting redundant bit, a code in which a first redundant bit obtained by dividing a cyclic redundancy check code forming a block pointer and a second redundant bit generated from a parity check matrix to said subblocks each are respectively added to data bits obtained by dividing data of block unit into a plurality of subblocks is used.
Claim 6
Dependent Claim
121 words
A method for transmitting time-sharing multidata according to claim 4, wherein said decoding of the error detecting and correcting code is comprised of the steps of performing the respective error correcting and detecting of said subblocks based upon said second redundant bit, detecting and correcting the error of said block unit based upon said cyclic redundancy check code, interpolating the subblock where the error detection and correction exist when any one of said subblocks has the error to be corrected and detected and at the same time, when the error in said block unit is detected and interpolating all the blocks when none of said subblocks has error correction and detection and when an error in said block unit is detected..
Claim 7
Dependent Claim
55 words
A receiving method for receiving the data transmitted according to the method for transmitting time-sharing multidata in claim 1, said receiving method comprising the steps of extracting data only on a desired channel from time-sharing data containing a plurality of received data channels with a clock of a predetermined period and error-correcting said desired data.
