Problems solved by technology

[0005] But because the hard disk in the conventional digital video recorder is a large-capacity recording medium, as the data that can be played for 5 hours is stored in the hard disk, and by the search key, when the recording position is jumped once every 5 minutes (search 1, 2, . .....k), in order to search for the last record position (tail), the user needs to input the search key on the remote controller 60 times from the head (Header), which brings great inconvenience to the data search operation, and requires Conduct long data searches

Embodiment Construction

[0021] The fast data search method of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] First, the fast data search method according to the present invention is applicable to figure 1 digital video recorder.

[0023] As shown in Figure 3:

[0024] S10, in the microcomputer 12 of the digital video recorder, if the user selectively inputs the search key through the remote controller.

[0025] The microcomputer 12 confirms the operation mode corresponding to the search key.

[0026] Such as Figure 4 As shown, on the remote controller adopting the method of the present invention, there are multiple search keys for the user to selectively designate the search mode. For example, the first search key (S1) corresponding to the jump mode, the second search key (S2) corresponding to the multiple change mode, and the third search key (S3) corresponding to the time search mode.

[0027] S11, at this time, confirm whether to...

Abstract

This invention relates to data rapid searching method, which has large capacity HD digital recorder and inputs search keys through remoter and sets the data research as jump mode and outputs display OSD image and then determines the digital keys input by remoter and searches the set record position relative to the digital key data record proportion to allow user select the research key on the remoter to operation and selects digital key on the input remoter.

Description

(1) Technical field [0001] The invention relates to a fast data search method, in particular to a fast data search method capable of fast searching data stored on recording media such as a hard disk of a digital video recorder. (2) Background technology [0002] figure 1 It is a diagram showing the structure of a conventional digital video recorder. Here, the digital video recorder is composed of hard disk (HDD) 10, hard disk recording HDR system 11, microcomputer 12, OSD (On-screen Display) generator 13, remote control signal receiver 14, memory 15 and other structures. [0003] The above-mentioned microcomputer 12 can operate and control the HDR system 11 according to the request (key input) sent by the user, and read and play the data recorded in the hard disk 10 or record and save the externally input data in the hard disk 10 . Such as figure 2 As shown, if the user inputs a search key (Search Key) on the remote controller once, the microcomputer 12 will perform a da...
