KR970017545A - Index information recording / reproducing apparatus and search method of DVCR (DVCR) - Google Patents

Abstract

The present invention relates to an index information recording / reproducing apparatus and method for a DVCR. More particularly, the present invention relates to an index information recording / reproducing apparatus and method for recording / reproducing various index information in a dummy area other than a data area in which an actual video signal is recorded on a track of a video tape for recording digital data And an index information recording / reproducing apparatus and a search method of a DVCR in which a title of a program to be searched, a program recording time and the like can be immediately known and characters can be easily input.

Therefore, the method of index search of the DVCR according to the present invention is devised to solve the above-described conventional problem of reproduction, and it is a first step of detecting whether there is index data according to the index data reproduction, A second step of determining whether to store the index data and recording a new program, a third step of displaying the index data and selecting whether or not the index search is to be performed, the fourth step of performing index search according to whether the index search is executed, And a fifth step of performing recording and index editing according to the selected recording, and recording the index data.

In the index information recording / reproducing apparatus of the DVCR according to the present invention, a bar code is attached to a video tape by using a separate additional device such as a bar code and a bar code reader in a conventional method for recording and reproducing index data, Reading the barcode using the reader, reading the indexed data corresponding to the number of the video tape stored in the memory of the VTR, that is, the barcode number, and displaying the read barcode number to the user, It is a device that can know index information immediately after loading a video tape.

Also, in a method of recording index data on a control track of a video tape and reproducing the index data, the index information can be reproduced immediately without rewinding the video tape after loading the video tape and without having to detect the head data of the index information.

Furthermore, since the index information to be recorded is recorded in a dummy area other than the area where the actual data is recorded, the amount of data actually recorded on the video tape is not changed at all.

Therefore, the index data recording and reproducing method of this method not only can easily find a program that a user desires when a plurality of programs are recorded on a video tape in a VTR for recording and reproducing digital data to be spread in the future, Information on which program is recorded is also a convenient device to know immediately after loading the video tape.
