Abstract:
A data processing apparatus and a data processing method which enable provision of an LDPC code that achieves good error-rate performance. An LDPC encoding unit performs encoding using an LDPC code having a code length of 64800 bits and a code rate of 24/30, 25/30, 26/30, 27/30, 28/30, or 29/30. The LDPC code includes information bits and parity bits, and a parity check matrix H is composed of an information matrix portion corresponding to the information bits of the LDPC code, and a parity matrix portion corresponding to the parity bits. The information matrix portion of the parity check matrix H is represented by a parity check matrix initial value table that shows positions of elements of 1 in the information matrix portion in units of 360 columns. The present technology apparatus and method may be applied to LDPC encoding and LDPC decoding.

Claim (Index 1):
A data processing apparatus comprising:\n an encoding unit configured to encode information bits into an LDPC (Low Density Parity Check) code having a code length of 64800 bits and a code rate of 24/30 on the basis of a parity check matrix of the LDPC code, wherein the LDPC code includes information bits and parity bits, the parity check matrix includes an information matrix portion corresponding to the information bits and a parity matrix portion corresponding to the parity bits, the information matrix portion is represented by a parity check matrix initial value table, and the parity check matrix initial value table is a table showing positions of elements of 1 in the information matrix portion in units of 360 columns, including 1504 2103 2621 2840 3869 4594 5246 6314 7327 7364 10425 11934 12898 12954 27 1903 3923 4513 7812 8098 8428 9789 10519 11345 12032 12157 12573 12930 17 191 660 2451 2475 2976 3398 3616 5769 6724 8641 10046 11552 12842 13 1366 4993 6468 7689 8563 9131 10012 10914 11574 11837 12203 12715 12946 432 872 2603 3286 3306 3385 4137 5563 7540 9339 9948 12315 12656 12929 1113 1394 4104 4186 7240 8827 11522 11833 12359 12363 12629 12821 12904 12946 14 441 1432 1677 2432 8981 11478 11507 12599 12783 12793 12912 12922 12943 1579 1806 7971 8586 9845 10357 11600 12007 12020 12339 12576 12817 12830 12904 20 546 3672 5538 6944 8052 8781 9743 12269 12393 12418 12549 12555 12718 1 3540 4397 5011 6626 8617 9587 10360 10602 11402 11983 12068 12495 12838 30 1572 4908 7421 8041 8910 8963 11005 11930 12240 12340 12467 12892 12933 33 2060 3907 4215 5545 8306 8655 8743 8806 9315 9364 10685 11954 12959 1338 2596 4876 5207 9555 10421 10929 11648 11739 12375 12416 12643 12742 12754 9469 10544 10932 11250 11426 11582 11846 12139 12202 12210 12356 12378 12873 12929 2681 3337 3616 6113 7078 8167 8624 9697 10908 11781 11855 12095 12175 12659 28 4086 5432 6555 6848 7368 8794 11483 11572 12414 12816 12894 12936 12957 5 5044 5572 9023 9192 9589 9979 10009 10855 10991 11715 12314 12610 12945 17 272 602 5681 6530 9572 9886 11061 11495 12238 12265 12483 12885 12955 22 2245 4282 4469 5007 6650 6733 10151 10401 11571 12004 12261 12805 12844 23 3270 4468 8621 9662 11240 11934 12091 12444 12691 12717 12858 12888 12917 740 1519 4923 6191 7878 8350 9293 10779 11020 11287 11630 12792 12862 12920 12 28 3584 6072 7079 8075 10477 11130 11383 11780 12341 12667 12818 12927 14 118 5283 5382 8301 9097 9413 9664 10437 10701 11124 12685 12730 12734 32 1426 3078 4325 5353 7780 9042 9928 10077 10377 10679 11191 11750 12611 1 669 3831 3980 5381 5412 6552 8453 9435 10243 11546 11821 11987 12807 232 483 919 1232 2156 2396 2990 3774 8539 8704 8819 10810 11868 12634 2381 7309 9334 348 6494 12623 4872 6257 11090 7 11970 11985 6615 12788 12855 1173 5269 12647 1949 7738 8116 17 4828 9175 2329 6034 12642 1254 2366 5013 2984 5078 5664 7423 10265 11528 1656 8526 8716 22 287 2837 18 100 3079 299 3171 12169 33 5920 11144 1286 3650 9309 2283 8809 12588 3199 8242 9081 2507 6846 8113 5211 8722 12689 1064 2592 8659 6136 6925 12958 1256 12789 12932 4274 8045 8788 1824 3209 6926 11 8899 12669 6249 6338 8730 641 9679 12831 3459 9876 11185 3226 6148 8173 9078 12126 12771 10907 11278 12731 3392 4020 12838 2814 11588 12909 6063 9214 11519 6064 6827 12683 1610 2452 6582 903 6289 8074 4592 8138 12952 2587 6271 9945 2733 11844 11893 581 4601 10020 14 5597 6049 343 3582 5931 5263 6521 12846 1394 2457 5251 11 4627 12747 2650 10366 12390 6285 11893 12062 10143 12892 12956 8448 11917 12330 4209 11693 12356 1529 2360 9086 5389 8148 10224 64 4876 12862 9483 12659 12887 3587 6767 12478 3122 5245 9044 3267 10118 11466 1347 3857 6705 9384 9576 11971 1366 8708 10758 412 4249 12863 1676 10488 11850 17 1605 2455 14 111 6045 11368 12919 12953 10588 11530 12937 4549 5143 12218 3088 4185 11674 23 2554 7823 6615 9291 9863 2229 3629 10855 3818 5509 12764 2740 11525 12914 8297 8611 12948 3606 11104 12920 5097 10412 12759 6502 7266 12072 5425 5490 10728 22 73 8462 32 12439 12657 8483 9540 10430 7275 7377 7420 5748 9726 12356 5672 6150 9156 28 3527 5857 520 7099 11335 405 6173 12865 5847 12843 12934 4289 7679 10386 2950 8021 12938 8844 11214 12955 2130 10760 12665 734 4790 12940 8 6991 12772 19 8205 11289 12 1440 9077 8670 8837 12951 3531 9166 12937 15 8901 8929 838 10114 11740 2648 9959 10934 323 7499 12877 5505 5659 11395 6627 12709 12933 364 1976 12888 8213 9124 12793 9588 10088 11108 299 890 11634 7368 7598 11602 28 4669 12585 15 27 12474 1426 3614 4205 30 2087 11147 6226 6259 12941 .
