Abstract:
PROBLEM TO BE SOLVED: To more surely transmit information exerting large influence upon reproduction quality, and perform real time transmission of information while communication bandwidth is used to the utmost. SOLUTION: This information transmitter transmits in real time frames of contents data to an information receiver, by constituting hierarchical structure from first hierarchy data of high priority level to third hierarchy data of low priority level, and receives status information showing issue of reception from the receiver. The information transmitter selects and transmits the hierarchy data of the highest priority level which can be transmitted within a limited time measured by a time measuring means, from among the hierarchy data for which transmission is not completed. The information receiver multiplexes only the hierarchy data which are normally received within the limited time from among the hierarchy data transmitted from the information transmitter, and reconstitutes and reproduces the frame.

PROBLEM TO BE SOLVED: To efficiently transfer data when the transferring unit of data is smaller than the erasing unit of a recording medium. SOLUTION: Every time a transferring device 1 reads data of a capacity equivalent to the integral multiple of the erasing unit of a recording medium 203 in a recording and reproducing device 2 from a recording medium 103 and transmits it, the device 1 receives status information from the device 2. Every time the device 2 records data of a capacity equivalent to the integral multiple of the erasing unit of the medium 203, the device 2 returns the status information to the device 1.

Abstract:
PROBLEM TO BE SOLVED: To easily and fast control a memory and also to easily and flexibly manage the memory for an information recording and reproducing device having a recording medium whose erase unit is larger than its write unit. SOLUTION: A recording medium 3 has an erase unit of a flash memory, etc., that is larger than its write unit. A recording medium control part 2 records the file data transferred via a transfer control part 5 at and after the head position of the erase unit. Then only a single piece of file data is recorded in the same erase unit and other file data are never mixed in the erase unit. Thus, the existing files can be collectively erased without being saved into an external buffer, etc., when the file data are rewritten. As a result, the memory management such as the reading of the file data, etc., can be facilitated.

Abstract:
PROBLEM TO BE SOLVED: To provide an image recorder in which a user himself/herself does not need to be an object and which performs various equipment control even when the user moves. SOLUTION: An object relative displacement detection part 14 detects a relative displacement pattern of the object from image data from a temporary storage part 12 which temporarily stores image data outputted from an image pickup part 11. One or more image pickup means dislocation patterns of an image pickup direction and/or a position of the image pickup part and predetermined additional recording information are associated and stored in a registration information storage means. It is judged whether the relative displacement pattern of the object detected by the object relative displacement detection part coincides or approximates any of the registered image pickup means displacement patterns, and when it is judged to coincide or approximate, recording information stored in the registration information storage means corresponding to the image pickup means displacement pattern judged to coincide or approximate is recorded in a recording medium together with the image data.

Abstract:
PROBLEM TO BE SOLVED: To form trial listening reproduced data by using additional data for response formed on the basis of additional data. SOLUTION: An additional data transmitter which receives a request for transmission of the additional data for response forms the additional data 83 for response and transmits the data to the request source. Content IDs, the number of trial listening sections, etc., are stated in the headers of the data 83 and further, the start positions for trial listening and the lengths of the trial listening sections are stated in the top portions of the additional frames by each of the on-line trial listening sections. The transmission request source for the additional data for response receiving the data 83 forms the trial listening reproduced data 84 by using trial listening data 81 and the data 83. The data 84 comprises the frames restored to the data higher in sound quality than the data 83 in the trial listening section R1 and the trial listening section R2 and comprises the trial listening frames in the other sections. This invention is applicable to an encoding system, additional data transmitter, data reproduction device, and data recording device. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To regenerate high-quality contents by reducing a risk of illegally forming high quality and by acquiring a small amount of additional data while the trial viewing and listening of the contents including music are enabled, and to further increase safety. SOLUTION: The number of coding units UN is assigned to 4 so that a narrow-band regeneration can be available for listening. Four pieces each of quantization accuracy information QN and normalization coefficient information NP are coded. In spectral coefficient information SP, a region Neg, from 4 coding units forward is ignored in the listening even if the whole bands are coded. In the region Neg, quantization accuracy information QN' at a wide band not coded at a normal position, normalization coefficient information NP' are coded. Providing the region Neg with a frame embedding the quantization accuracy information QN' and the normalization coefficient information NP' and an embedding-free frame further increases safety with a small data amount of a high-quality file retaining.
