Description

Method for auto-recording content of concern field in a TVCR

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic recording method in a TVCR. In particular, a TVCR having a combined function of a television and a video cassette recorder sets voice information desired by a user, and recognizes and detects voice information set by the user among received broadcast signals. The present invention relates to a method of automatically recording a field of interest in a TVCR, which automatically records a broadcast signal received for a predetermined time.

In general, a television separately detects and demodulates and amplifies an airwave broadcasting signal of a predetermined channel received through a tuner into a video signal and an audio signal, displays a video signal through a water pipe (CRT), and outputs an audio signal through a speaker. It is a device that can output and watch television broadcast programs.

Meanwhile, a video casette recorder separates a broadcast signal received from a tuner into a video and audio signal, records the video signal on a video cassette tape using a video head and an audio head, respectively, and records the recorded video and audio signals. It is a device that can reproduce and output by using the head and the audio head.

On the other hand, the above-described television and video cassette recorder are typically provided together so that the viewer can output the video tape signal including the video and audio signals reproduced in the video cassette recorder through the television's receiving tube and speaker, You can play movies and educational programs recorded on the TV.

However, the above-mentioned two electronic products are integrated into the characteristics of the user because it is convenient for the user's point of view, and a TVCR was developed as a combination product having both these functions. Such a TVCR is provided with two tuners as the first tuner. At the same time, the broadcast signal received by the second tuner can be recorded on a video cassette tape while watching the received broadcast program, or the standby mode is provided after recording a broadcast program being watched with one tuner or setting reservation information. Automatic recording can be performed using this set reservation information.

On the other hand, in TV, its functions are diversified to meet the needs of viewers, and various functions are added to satisfy the various needs of these viewers.

For example, in a broadcasting system providing an extended data service (EDS), data for broadcast programs and scheduled recording on a broadcast signal, for example, a channel, a broadcast category (eg, news, drama, sports, etc.), a broadcast start / KBPS decoder on the video receiving device side by converting various program information such as the end time / standard time data, etc. into digital signals and inserting them in any horizontal line during the vertical blanking interval (VBI) This signal is decoded so that broadcasting program reservation recording function and automatic time correction function can be performed.

In addition, as a broadcasting system for providing such an EDS, there are, for example, Korea Broadcasting Program System (KBPS) in Korea, VPS (Video Programming System) in Germany, and PDC (Program Delivery Control) in the UK.

Therefore, conventionally, reservation recording is performed by using the reservation recording data included in the EDS data of the broadcasting system providing the above-described EDS, or the user directly inputs the information for the reservation recording so that the user can enter even when the user is absent. Reservation recording was performed based on the reservation recording information.

However, in the above-described conventional reservation recording method, although one user can reserve recording of one broadcast program in a state where the user is aware of the contents of the broadcast program in advance, an area of interest of the user (for example, , Technical fields, people, events, etc.), there was a problem that can not extract and record only parts.

For example, in a news program, users' interests in different fields of politics, economy, society, culture, and sports vary according to individual tastes. In addition to the program, other programs can be broadcasted, and it is difficult to pre-record only a part of the broadcast program in a state where the user recognizes the broadcast information.

Accordingly, in the present invention, when a voice corresponding to a keyword is set among the broadcast programs received while the user's field of interest is set as a keyword and is stored, a method of automatically recording the broadcast program received for a predetermined time has been sought. .

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to receive a broadcast program on a predetermined channel set by a user when in standby mode in a TVCR equipped with a television function and a video cassette recorder function. Voice recognition is performed on the received broadcast signal to detect whether a voice signal of a predetermined keyword corresponding to the user's interest set by the user is detected. When a voice signal corresponding to the set keyword is found, the broadcast signal received for a predetermined time is automatically detected. The present invention provides a method of automatically recording a field of interest in a TVCR so that a user can conveniently record and watch a broadcast program that handles a user's field of interest.

Through the reproduced signal can be viewed.

Meanwhile, the user selects an appropriate keyword from the field of interest to be recorded and inputs it through the key input unit 10. In this case, a desired keyword can be input by selecting and combining consonants and vowels sequentially by using an OSD (on screen display) function.

In addition, the channel for recording can use the channel set at the time when a television is powered off, and can also separately set the channel for recording.

Next, when the power on / off key signal of the key input unit 10 is applied to the microcomputer 20 in the active mode such as the television mode or the video mode described above, the microcomputer 20 switches to the standby mode and the predetermined minimum power consumption. By this, the key signal from the key input unit 10 is waited for input.

At this time, in order to automatically search for and record the broadcast of the field of interest set by the user as a keyword as described above, the microcomputer 20 of the present invention determines whether the TVCR is switched to the standby mode described above. In operation 300, the microcomputer 20 controls the tuner 30 to be tuned to a predetermined channel preset by the user (step 302).

Then, the tuner unit 30 outputs a broadcast signal received by being tuned to the corresponding channel, and the received signal is applied to the image and audio signal processing unit 40 so that the audio signal is separately detected and the voice recognition unit 80 is provided. Is applied.

Next, the voice recognition unit 80 recognizes the voice in the audio signal applied from the image and audio signal processing unit 40 and applies the recognized voice pattern data to the microcomputer 20 (step 304).

Then, the microcomputer 20 compares and determines whether there is a voice pattern corresponding to a predetermined and stored keyword among the voice pattern data applied from the voice recognition unit 80 (step 306).

At this time, if there is a voice pattern corresponding to a predetermined keyword among voice recognized voice patterns, that is, a broadcast program received from the tuner unit 30 includes the same voice as a keyword of a field of interest desired by the viewer, and is currently received. Recognizing the program as a program of the user's interest, the microcomputer 20 controls the recording signal processor 90 and the deck unit 100 to load the broadcast signal received from the tuner unit 30 into the deck unit 100. The recorded video tape is recorded for a predetermined time (step 308).

On the contrary, if there is no voice pattern corresponding to the preset keyword among the voice recognized voice patterns, the microcomputer 20 returns to step 302 and proceeds with the broadcast program for the field of interest of the user who wants to continuously record on the predetermined channel. It is determined whether a program is received.

At this time, the end of the video cassette tape is detected as in the normal recording mode, or if the video cassette tape is not loaded, the user can be recognized by using an on-screen display (OSD) function (not shown).

Therefore, it is possible to extract and record the contents of the user's field of interest from all programs broadcast on a specific channel.
