PROBLEM TO BE SOLVED: To provide a reproduction sequence storage method and a reproduction sequence storage apparatus capable of automatically reproducing an optical disk in a predetermined sequence of musical pieces. SOLUTION: The reproduction sequence storage apparatus comprises: an optical pickup 13 for reproducing information signals recorded in the optical disk 11; a memory 18 for storing reproduction sequence information corresponding to each disk-like recording medium for each disk-like recording medium; and a system controller 19 which discriminates the disk-like recording medium, collates the reproduced information signal with the reproduction sequence information stored in the memory 18, and controls to reproduce the collated information signal based on the reproduction sequence information, therefore, when replacing the recording medium with another recording medium, and in a case that a sequence for listening to musical pieces is predetermined for each recording medium, it is not necessary to perform the same operation each time, the operability can be improved and the recording medium can be reproduced in the predetermined order of musical pieces automatically.

Abstract:
PROBLEM TO BE SOLVED: To satisfy request from more consumers for the functions of the device and prices for the device. SOLUTION: Functions, A, B, C, D, E, F, G, H, I are loaded in an audio device, or a video device through a hardware circuit, or a computer program. In the functions, E, F, G, the use is restricted by setting a function restriction flag to ''1'' , provided that the functions, E, F, G are used within the number of a trial-allowable days. The device applies for the purchase of the functions E, F, G to a key issuer. The key issuer issues a release key for the device. A cellular telephone terminal acquires the release key from the key issuer. The release key may be transmitted to the device through infrared communication. The device rewrites the function restriction flag by using the release key. The CPU (Central Processing Unit) of the device performs no function having the function restriction flag, '1' when the number of actual trial days reaches the number of trial-allowable days.

Abstract:
PROBLEM TO BE SOLVED: To provide a receiver and a reception method by which a proper channel, in response to a reception state for actual channels can be selected so as to obtain a stable reception state. SOLUTION: This invention provides a reception method by which the number of consecutively used times of channels for a prescribed number of times in the past and the average time of the number of consecutively used times are obtained, as channel quality information denoting a reception state of each channel, and a channel with the best channel quality can be obtained, on the basis of the information of the average value. Furthermore, this method switches the channels for each prescribed time to count the number of error occurred at that time in the case of start and decides and selects a channel having fewest errors generated as an initial channel.
Abstract:
PROBLEM TO BE SOLVED: To prevent voice from being suddenly broken off during performance of music, etc., by delaying timer setting until an effective signal identified as continuing has been judged as stopped. SOLUTION: The intermediate moment when reproducing of a track Tr #N ends and shifts to the next track Tr #N+1 is defined as a new sleep timer setting time Sta, and a power supply is stopped correspondingly to this moment. In the case of audio data, for example, the other data sections except this inter-music section are regarded as effective signals and the data sections corresponding to the inter-music sections are regarded as ineffective sections. With such a sleep operation, the power supply of the equipment is halted at the inter-music timing, and hence the power source is halted at the timing when the music ends. Thus, it can be avoided to give a user such an unpleasant feeling as that performance of music is broken and a voice output is stopped.
Abstract:
PROBLEM TO BE SOLVED: To perform remote control operation by utilizing a communication medium which has less restriction concerning directivity such as an IP network and a communicable range.SOLUTION: Since bi-directional communication is possible between a remote controller and an operation targeted device, it is possible to perform certain communication by delivery confirmation, to handle a complicated command system using GUI operation, and to transmit large-capacity data such as moving image streaming by using a relatively wide band. A television receiver as a remote-controlled object distributes moving image data such as a slave screen to an IP remote controller through an IP network, and the moving image data can be viewed at a side of the IP remote controller.
Abstract:
PROBLEM TO BE SOLVED: To more easily specify a device being present in front of a user than the prior arts even when a communication means of a low communication velocity or a communication means limited in the number of transmittable bits is used, in a control device and a device to be controlled that are communicable with each other over a network, a device specification system and a device specification method capable of specifying an opposite-side device between the devices. SOLUTION: There are provided: a control device 110 for transmitting, to a device to be controlled 120 communicable using a wireless communication system limited in at least either directivity or a transmittable distance, a device specifying signal specifying the device; and the device to be controlled 120 for transmitting a response to the device specifying signal toward a network 101 through multicasting or broadcasting when the device specifying signal is received from the control device 110. The control device 110 specifies the device to be controlled 120, that has transmitted the response received from the network 101, as a device that has received the device specifying signal transmitted from the control device 110 itself.

Abstract:
PROBLEM TO BE SOLVED: To control two or more devices in an interlocked way through a simple operation. SOLUTION: An interlocking control information management unit 87 stores interlocking control information made up of interlocking control conditions, where conditions for selecting an interlocking operation pattern defining procedure of each pattern name and transmitting control commands sequentially to two or more devices, and an interlocking operation pattern are described. In a control pattern analyzing unit 89, the interlocking control pattern is analyzed, and each control command for controlling operation of devices based on the analyzed result is generated sequentially and fed to a network interface 81 or to an infrared communication control unit 90. The device and the method can be applied to a reproduction system for reproducing contents. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To normally store the whole of target contents in spite of shortage of a storage capacity of a storage medium in storage of the target contents without deletion of stored contents already stored in the storage medium. SOLUTION: In storage of contents in a contents storage part 21 of a storage reproduction device 1, a residual capacity of a contents storage part 33 is checked by a residual capacity calculation part 23. When the residual capacity is lower than a threshold value, contents already stored in a contents storage part 33 are transmitted to a server device via communication I/F20 to be stored in a storage medium in the server device. The contents transmitted to the server device are deleted from the contents storage part 21 of the storage reproduction device 1, and contents to be stored can be stored in the contents storage part 21.

Abstract:
PROBLEM TO BE SOLVED: To provide a program update system capable of preventing using a simple arrangement the illegal acquisition of programs and of significantly reducing the amount of effort needed for operation and maintenance. SOLUTION: When the program implemented by a terminal device is to be updated, a program-providing server, based on version request information that the terminal device sends along with device identification information, authenticates the terminal device according to the device identification information and encrypts the version information for transmission. Based on the version information decrypted, the terminal device determines whether the program needs to be updated; if it needs to be updated, program request information is transmitted along with the device identification information; after the program providing server authenticates the terminal device, based on the device identification information, an update program is encrypted and transmitted; and using the update program decrypted, the terminal device updates the program implemented.
