Embodiment approach 1

[0075] In Embodiment 1, a data transmission and reception system will be described in which a database file of audio data is compared between an in-vehicle recording and reproducing device and a home recording and reproducing device, and the in-vehicle recording and reproducing device is copied (copied) from the home recording and reproducing device. Audio data missing from the device's database file.

[0076] figure 1 It is a block diagram showing the configuration of the data transmission and reception system according to Embodiment 1 of the present invention. This transmission and reception system is a system for transmitting and receiving data between two recording and reproducing devices, and includes an in-vehicle recording and reproducing device 100 and a home recording and reproducing device 200 .

[0077] The in-vehicle recording and playback device 100 has a storage unit 101 capable of storing a plurality of digital contents such as video data and audio data, a comm...

Embodiment approach 2

[0106] In this second embodiment, a data transmission and reception system in which priority is further used as information on audio data in the data transmission and reception system described in the first embodiment will be described.

[0107] Figure 4 It is a block diagram showing the configuration of the data transmission and reception system according to Embodiment 2 of the present invention. In this data transmission and reception system, the in-vehicle recording and reproducing device 300 has a priority determining unit 301 in addition to the structure of the in-vehicle recording and reproducing device 100 in the first embodiment, and the home recording and reproducing device 400 is based on the structure of the home recording and reproducing device in the first embodiment. In addition to the configuration of the recording and reproducing apparatus 200 , it further includes a priority determination unit 401 . In addition, about the same part as Embodiment 1, the same ...

Embodiment approach 3

[0121] In Embodiment 3, a data transmission and reception system for bidirectionally downloading audio data between an in-vehicle recording and reproducing device and a home recording and reproducing device will be described.

[0122] Figure 7 It is a block diagram showing the configuration of the data transmission and reception system according to Embodiment 3 of the present invention. In this data transmission and reception system, the vehicle-mounted recording / reproducing device 500 has a transmission unit 501 based on the structure of the vehicle-mounted recording / reproducing device 300 according to the second embodiment. In addition, about the same part as Embodiment 2, the same code|symbol is attached|subjected, and detailed description is abbreviate|omitted. In addition, the in-vehicle recording and reproducing device 500 has Figure 5 In the database file 320 shown in , the home recording and playback device 600 has a database file 420 .

Abstract

An on-vehicle recording / reproduction device (700) in a data transmission / reception system includes: an extraction section (502) for comparing a database file (710) to a received database file (610) and extracting information on audio data recorded in a home recording / reproduction device (600) but not recorded in the on-vehicle recording / reproduction device (700); a transmission section (501) for transmitting audio data recorded in the on-vehicle recording / reproduction device (700) but not recorded in the home recording / reproduction device (600) which data has been extracted by the extraction section (502), to the home recording / reproduction device (600); and a delete decision section (701) for deciding whether to copy a musical composition into the home recording / reproduction device (600) or delete it from a storage section (101) of the on-vehicle recording / reproduction device (700) by checking the 'copy source', the 'copy destination', and the 'priority' as items of the database file (710).

Description

technical field [0001] The present invention relates to a system for transmitting and receiving data, in particular to a data transmitting and receiving system for transmitting and receiving digital data between two recording and reproducing devices, a data transmitting and receiving method and a recording and reproducing device. Background technique [0002] In the existing car audio system, it is mainstream to bring removable media such as CD (Compact Disc) and user-recorded MD (MiniDisc, Mini Disk) into the car for audio-visual music. In recent years, it is possible to store a large amount of audio data by installing an in-vehicle hard disk in a car. As a method of storing music in such a vehicle-mounted hard disk, there is a method of copying from a semiconductor memory, or a method of directly copying audio data after connecting the hard disk to a PC (personal computer) when the hard disk can be removed. [0003] However, there is a file synchronization technology that...
