Abstract: PROBLEM TO BE SOLVED: To generate listening data on trial wherein only a listening area on trial whose header is of a fixed length and which has no silent reproduction part is continuously reproduced. SOLUTION: A contents ID, a contents reproduction time A or the like are described in the header of original data 71. A listening area 1 on trial and a listening area 2 on trial are distinguished from a protective area 1 to a protective area 3 other than the listening areas 1 and 2, and encoding suitable to the respective areas is carried out. Frame orders are exchanged, and a header with a changed reproduction time is attached to generate listening data 73 on trial (listening data on trial to be distributed) subjected to frame order change, wherein all of the listening areas on trial are shifted to the front of a frame string. Since the listening area 1 on trial of a reproduction time B and the listening area 2 on trial of a reproduction time C are shifted to the front of the frame string, the reproduction time described in the header of the listening data 73 on trial subjected to the frame order change is 'B+C'. This invention can be applied to an encoding device, a data reproducing device or a data recorder. COPYRIGHT: (C)2004,JPO

Abstract translation: 要解决的问题：为了在试用中产生听力数据，其中只有一个试验中的标题为固定长度并且没有静音再现部分的聆听区域被连续再现。 解决方案：在原始数据71的标题中描述内容ID，内容再现时间A等。在试用的聆听区域1和试听的收听区域2与保护区域1区分为保护 除了收听区域1和2之外的区域3，并且执行适合于各个区域的编码。 帧顺序被交换，并附加具有改变的再现时间的标题，以产生经过帧顺序改变的审判（待分发的试听数据）的收听数据73，其中所有的试听聆听区域都被转移到前面 的框架串。 由于在再现时间B的试用中的收听区域1和再现时间C的试听的收听区域2被移动到帧串的前面，所以在受试的听力数据73的标题中描述的再现时间 帧顺序改变是'B + C'。 本发明可以应用于编码装置，数据再现装置或数据记录器。 版权所有（C）2004，JPO

Abstract: PROBLEM TO BE SOLVED: To reduce risk of illegally improving the quality of contents in a method for reproducing contents of high quality by acquiring comparatively small quantity of data while allowing the trial listening of music contents or the like. SOLUTION: In decoding trial listening data by encoding data indicating 0-bit allocation to each four encoding units on the high area side out of quantization accuracy information QN and normalization coefficient information NP as trial listening data including dummy data, the spectral coefficient information of an area Neg part is neglected. A pseudo-code sequence such as a pseudo random number sequence is padded in a free area of a code sequence to be the trial listening data. When the trial listening data is tried to be illegally extended to a wide area, whether the extended code sequence is a correct code sequence or not can not be judged, so that illegal extension can be prevented and the safety of the trial listening data can be improved.

Abstract: PROBLEM TO BE SOLVED: To enable an efficient language practice and to provide an information reproducing device, etc., for effectively utilizing the capacity of a recording medium. SOLUTION: The sentence to be recorded on the recording medium 3 is read out by a recording medium control part 2 of the information reproducing device 1. By a reproduction control part 5, the reproducing process is applied to the sentence read out by the recording medium control part 2 to output the sentence from a reproduction output terminal 12 as voice data. Consecutively, the control of the recording medium control part 2 is stopped for a certain period after one sentence recorded on the recording medium 3 is outputted from the reproduction control part 5, thereafter, the next sentence is reproduced by the same process as the above.

Abstract: PURPOSE: To enable random access by controlling an information to be treated in a specified unit in a specified unit, and controlling information which is not required to be treated in a specified unit in a smaller unit. CONSTITUTION: When an input information block or a reproducing information block is held in a buffer memory 101, a storage region in the buffer memory 101 can also be used by changing over a recording function by a reproducing function respectively, but the reproducing function can be operated simultaneously and easily in the recording function when the buffer memories are fitted for the recording function and for the reproducing function respectively. That is, recording operation and reproducing operation are controlled in time division to an information recording medium being constituted of a semiconductor memory, a magnetic disk, etc., and enabling random-access, thus performing the reproduction of information required during recording operation and the recording of information generated during reproduction.
