摘要:
A data reproduction apparatus and a data reproduction method can alleviate the workload of a special processing operation of fast forward or reverse data reproduction and improve the data access speed for fast reproduction of data. The data reproduction apparatus comprises an optical pickup 2 for reproducing data from an optical disk 1, a sector detector 4 for detecting a first piece of data information indicating if a data is to be output as signal or not, a ring buffer memory 6 for storing data, an error correction circuit 7 for correcting errors in the data to be output as signal as indicated by the first piece of data information out of the stored data, a stream detector 10 for detecting a second piece of data information indicating the data to be out as signal out of the data corrected for errors, decoders 13, 16 for decoding the data corrected for errors and stored in the ring buffer memory 6 as signal to be reproduced and a system controller 22 for control the data to be decoded and the data not to be decoded by referring to the first piece of data information and the second piece of data information detected by a second data information detection means.
摘要:
Error correction decoding apparatus decodes error correction encoded data reproduced from a recording medium by decoding the encoded data to produce decoded data in frame units and by generating decoding information in frame units; the decoded data and decoding information are stored in correspondence by frame unit and the decoded data and decoding information are retrieved from storage while frame synchronizing with address data representing a physical location of the encoded data on the recording medium.
摘要:
A data decoding apparatus and the method and a data reproduction apparatus which reduces capacity of a memory used for decoding and speedily accesses to data to be read. In a data decoding apparatus (50) and the method which decodes coded data (S2) which is recorded in a recording medium (2), the coded data (S2) read from the recording medium (2) is stored in a memory used for decoding (51), data information of data to be read is detected from decoded data which is generated in the middle of decoding the coded data (S2), the data information is stored in a data information storage means and the output of decoded data (S10) is controlled on the based on the data information, thereby the output of the decoded data (S10) is controlled based on the data information independent of decoding of the coded data (S2).

摘要:
Decoding apparatus and method set interpolation flags in units smaller than an ECC block. The PI1 flag indicating an error on a row-by-row basis is generated for the first error correction result, while the PI2 flag also indicating an error on a row-by-row basis is generated for the second error correction result in the ECC block. The PO flag indicating an error on a column-by-column basis is further generated for the error correction result in the ECC block. Following these processing operations, the PI1, PI2 and PO flags are used for generating the interpolation flags.

Information recording and playback apparatus, content management method, and content management program. When data of copyright-protected content is recorded in a general-purpose HDD, illegal copying of the content is prevented. Each time when content is recorded in the HDD and when content recorded in the HDD is moved to a Blu-ray disc (BD), a random number output section outputs unique verification information (a random number) and overwrites the unique verification information in the corresponding verification files of the HDD and an EEPROM. Then, when the content recorded in the HDD is to be moved to the BD, a verification section verifies the verification information (random number) recorded in the verification file of the HDD against the verification information (the random number) recorded in the verification file of the EEPROM, and permits the movement of the associated content only when they match.

Provided is a manufacturing method to prevent devitrification of a bulb in a high pressure discharge lamp used for a projector. The method is for manufacturing a high pressure discharge lamp which uses, as a light source, a bulb made of fused quartz and including a tungsten electrode, and which is horizontally installed when the lamp is driven for actual use. The method includes the step of initially driving the bulb with an optical axis thereof being set horizontally before the high pressure discharge lamp is shipped. In the initial driving step, the rotation angle around the optical axis of the bulb is offset by 45° or more and 135° or less relative to the rotation angle around the optical axis of the bulb when the lamp is driven for actual use.

Provided is a preventive and/or therapeutic agent for malaria, comprising, as an active ingredient, 5-acetamido-4-oxo-5-hexenoic acid (Alaremycin) or a derivative thereof. A preventive and/or therapeutic agent for malaria is used which comprises, as an active ingredient, Alaremycin or a derivative thereof represented by formula (I) (wherein R1 represents a hydroxy group, an amino group, or a substituted or unsubstituted straight chain or branched alkoxy group or alkylamino group having 1 to 8 carbons; R2 represents hydrogen, a substituted or unsubstituted straight chain or branched alkyl group having 1 to 8 carbons, or a substituted or unsubstituted aromatic group having 4 to 10 carbons; and R3 represents hydrogen or a methyl group).
