The present invention relates to a method of providing recording reservation data to a VCR using a TV, and an apparatus applied to the method. According to the conventional methods up to now, the user has provided all the recording reservation data to the VCR by manufacturing a Video Cassette Recorder (VCR).

That is, when performing the recording reservation mode, everything has been performed only in the VCR itself.

In addition, according to the conventional methods, the recording reservation mode is performed by using separate information on some lines of the broadcast signal.

The separate information is provided by broadcasting stations, and is generally separated from the video signal in some lines of the broadcast signal, that is, in a vertical blanking interval.

For example, separate information carried on broadcast signals by European broadcasting stations will be described.

First, there is a teletext signal.

The teletext signal is carried on some lines of the broadcast signal and is composed of digital data corresponding to a character or a picture.

The teletext data includes news information, stock information, entertainment information, leisure information, sports information, and TV guide information.

At present, European broadcasting stations provide information corresponding to 100-999 pages through teletext signals, and each page is composed of sub-pages and multi-pages to provide further detailed information. do.

One piece of information included in the teletext signal includes VPT (Vided Programmable Teletext) information.

The VPT means TV program guide information and provides detailed information about broadcast programs.

Accordingly, the VCR may perform the recording reservation mode more conveniently using the VPT information. A description of the VPS signal is as follows.

The VPS signal is composed of various kinds of codes.

The codes include general code, interrupt code, dummy code, system code, and the like. The general code is a code for a scheduled recording start time of a desired broadcast program, and the interrupt code is a code for notifying a broadcast signal section irrelevant to an actual broadcast program such as an advertisement.

In addition, the dummy code is a code relating to an end time of a desired broadcast program, and when a problem occurs in using a VPS signal due to a problem in equipment, the system code uses a time set in the VCR to reserve a program. It is a kind of instruction code to perform.

The PDC (Program Delivery Control) signal will be described. The PDC signal includes all codes included in the VPS signal, and further includes a continuous code.

The continuous code indicates a continuation of a desired broadcast program.

For example, in the broadcast of a sports game, the sports game may proceed after the rectified relay time.

The continuous code indicates such information. Therefore, the VCR can use this PDC signal to completely reserve the desired sports game.

According to the conventional methods, the VCR had to include a decoder for detecting the separate information from the broadcast signal in order to use the above separate information provided from the broadcasting stations in the reserved recording mode or the recording reservation mode.

In practice, since each decoder is an expensive device, in order to include all the decoders for detecting all the separate information provided from the broadcasting stations in the configuration of the VCR, the manufacturing cost of the VCR is very high. For example, it may be divided into a VCR having a simple function having no decoders at all, a VCR having a VPS decoder only, a VCR having an Auto Channel Mapping System (ACMS), and a VCR having both a VPS decoder and an ACMS.

In this case, the ACMS recognizes a broadcasting station name and adjusts the broadcasting station number according to the region where the VCR is located, and maps the channel number and the adjusted channel number of the original broadcasting station to provide the mapped channel tuning data. It is for.

For example, a broadcast signal of a broadcasting station may be received with a channel number of "10" in the central region, but may be received with a channel number of "11" in regions other than the central region.

In this case, the ACMS finds the control number "11" and provides channel tuning data consisting of "10" and "11".

On the other hand, the contents of the reservation recording of the VCR using the teletext decoder of the TV filed in the patent application No. 96-4837 filed by the present applicant, there are the following problems.

First, a specific method for detecting only the desired information from the teletext information stored in the TV side memory has not been presented.

In other words, the teletext broadcasting information varies depending on the broadcasting stations, but at least 10 or more kinds of reservation information desired by the VCR is sufficient, and there is no problem in detecting it. It can be easily recognized by the VCR when it is transmitted to the network.

Secondly, there is essential information used for recording reservation of general VCR, but only recording reservation information extracted from teletext broadcasting signal transmitted from TV does not store all the recording reservation essential information of VCR side in memory, so there was a problem in performing recording. .

Accordingly, the present invention has been made to solve the above-mentioned problems according to the prior art, an object of the present invention is to extract only the information desired by the VCR of the teletext information stored in the memory of the TV that can conveniently perform the reservation mode The present invention provides a method and apparatus for providing recording reservation data to a VCR.
