Abstract:
An electronic apparatus, having functions on which use limitations can be imposed, in which a variety of functions are loaded on the electronic apparatus by hardware circuitry or by computer programs. Use of a certain function(s) is limited by setting a function limiting flag to "1", provided that an other function(s) are usable within a period of a preset number of days of possible test use. An application is made from the apparatus to a key issuing source for purchasing usable functions. The key issuing source then issues a limitation removing key. The limitation removing key may be acquired from the key issuing source by a mobile phone terminal and transmitted to the apparatus by infrared ray communication. The apparatus rewrites the function limiting flag by this limitation removing key. If the number of days of actual test use has reached the number of days of possible test use, the CPU of the apparatus does not carry out the function(s) the function limiting flag of which is "1".
Abstract:
A communication medium with fewer limitations on the directivity or available communication range, such as an IP network, is used to perform a remote control operation. Since two-way communication can be carried out between a remote controller and a device to be operated, it is possible to provide more reliable communication by means of a delivery confirmation, to handle a GUI-based complex command scheme, and to provide large-volume data transmission, such as moving-image streaming, using relatively broad bands. A television receiver to be operated by the remote controller distributes moving-image data, such as a child view, to an IP remote controller through an IP network so that the data can be viewed on the IP remote controller.
Abstract:
A reproducing apparatus (10) for a recording medium (1) recorded with compressed image data, audio data relating to musical accompaniment, character data relating to musical accompaniment, data showing the musical accompaniment scale, scale data for a scale change position and a position after a scale change and data showing a time passage relating to an audio signal relating to the musical accompaniment has an image reproducing unit, a reproducing unit (11), a signal generating unit (45, 67) and a mixer (44, 53). The image reproducing unitt decodes and reproduces image data read-out from the recording medium (1). The reproducing unit (11) reproduces audio signals relating to musical accompaniment, character data and data displaying a scale from the recording medium. The signal generating unit (45, 67) generates a harmony signal which becomes a chord for the audio signal outputted from a microphone (41) based on data displaying the scale played back by the playback part. The mixer (44, 53) mixes and outputs the audio signal outputted from the microphone (41), the audio signal reproduced be the reproducing unit (11) and the harmony signal from the signal generating unit (45, 67).
Abstract:
In a method of reproducing image data recorded on a recording medium (30) using an MPEG (Moving Picture Coding Expert Group) technique or the like, the image data including first image data where all image information for one frame in question is compressed and second image data where information on a change in image information for frames before and after the frame in question is compressed, when a predetermined portion of the image data recorded on the recording medium is to be reproduced the reproduction is started from a portion of the recording medium where the first image data is recorded.
