Abstract
Abstract In a method for transmitting interleaved data, when the respective data blocks (DB n ) to be transmitted are interleaved and augmented by the error correcting parity codes (Pi, Qi) before being transmitted on the transmission channel, a prescribed number of dummy data are provided between the respective data blocks (DB n ) so that the data block (DB n ) and the neighboring data blocks (DB n-1 , DB n+1 ) are not in the interleaving relation. In this manner, data addition, correction and substitution can be made easily for each data block or a group of blocks without influencing the error correction parity codes of the remaining block data.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A data transmission method for interleaved data in which input data elements forming each data block (DB n ) are scrambled in the temporal order thereof by an interleaving operation, in which the interleaved input data elements are divided into groups each composed of a prescribed number of data elements and in which error correction parity codes are generated and affixed to the prescribed number data for transmission on a transmission channel, characterized by the step of using a prescribed number of dummy data elements arrayed with the input data forming said data blocks (DB n ), for generating and affixing the error correction parity codes.
Claim 2
Dependent Claim
106 words
A data transmission method for interleaved data in which input data elements forming each data block (DB n ) are scrambled in the temporal order thereof by an interleaving operation, in which the interleaved input data elements are divided into groups each composed of a prescribed number of data elements and in which error correction parity codes are generated and affixed to the prescribed number data for transmission on a transmission channel, characterized by the step of using a prescribed number of dummy data elements arrayed with the input data forming said data blocks (DB n ), for generating and affixing the error correction parity codes.
Claim 3
Dependent Claim
44 words
The method according to claim 1, characterized by the step of arraying said dummy data elements to compensate for the deficiency of the input data arrayed with said prescribed number of data elements for generating and affixing at least said error correction parity codes.
Claim 4
Dependent Claim
118 words
A data transmission method in which, when input data elements forming a data block (DB n ) are divided into groups each composed of a predetermined number of data elements and are arrayed two-dimensionally, error correction parity codes are generated and affixed to the predetermined number of data elements of the two-dimensionally arrayed data arrayed in a direction different from the arraying direction of the input data elements and the data elements are sequentially transmitted along said different direction, characterized in that dummy data elements are arrayed with said input data elements to compensate for the deficiency of the input data elements arrayed in said different direction to generate and affix the error correction parity codes (Pi, Qi).
Claim 5
Dependent Claim
118 words
A data transmission method in which, when input data elements forming a data block (DB n ) are divided into groups each composed of a predetermined number of data elements and are arrayed two-dimensionally, error correction parity codes are generated and affixed to the predetermined number of data elements of the two-dimensionally arrayed data arrayed in a direction different from the arraying direction of the input data elements and the data elements are sequentially transmitted along said different direction, characterized in that dummy data elements are arrayed with said input data elements to compensate for the deficiency of the input data elements arrayed in said different direction to generate and affix the error correction parity codes (Pi, Qi).
Claim 6
Independent Claim
25 words
The method according to any one of claims 1 to 3, characterized by the step of setting the dummy data to the "0" logic level.
Claim 7
Independent Claim
37 words
The method according to any one of claims 1 to 4, characterized by the step of arraying said dummy data elements at the leading portion of the input data elements forming the data block (DB n ).
Claim 8
Independent Claim
37 words
The method according to any one of claims 1 to 4, characterized by the step of arraying said dummy data elements at the trailing portions of the input data elements forming the data block (DB n ).
Claim 9
Independent Claim
38 words
The method according to any one of claims 1 to 4, characterized by the step of arraying said dummy data elements at the leading and trailing portions of input data elements forming the data block (DB n ).
