Description

VSI system with remaining recording function

The present invention relates to a VSI system having a remaining recording control function. In particular, it is possible to perform one-touch automatic recording until the end of a program by using program remaining time data of a video signal received from a broadcasting system such as VSI. By doing so, this system can be easily implemented.

G-Code is known to implement simple reservation recording using broadcast signal in VSI system. This is a simple reservation recording system developed by GEMSTAR of USA, which makes reservation recording convenient. In order to do this, a specific number is assigned to a specific pro so that the user can enter the number of scheduled recordings.

Such a code can be reserved by inputting a code that codes up to 8 digits of 4 data of channel, date, start time, and broadcasting length (C, D, T, L). After entering the code, select 'Weekly / Once / Monday-Friday' and leave the remote control next to VSIal. When the scheduled time comes, IR will transmit the infrared and the VSI will start recording. It is compatible with each company's VSI, and there are VSI and TV with this function.

The PLUS CODE system is designed to summarize these four elements into separate numbers called plus codes, which are based on the region in which they are used: G-Code, VCR PLUS, SHOW VIEW. ), Called KPS.

On the other hand, as shown in FIG. 2, the CODE code carries and broadcasts a code signal divided into a clock and a W byte byte synchronization unit, a data head unit, and a data unit in a vertical synchronization section of the video signal.

In addition, there are four elements required to record a specific TV broadcast: date, channel, start time, and broadcast length. If you set the date as 31 days, 125 channel types, and the start time interval in 5 minutes a day, 288 (60/5 = 12, 12 * 24 = 288), and the length of the broadcast is 3 hours up to 5 minutes. There are 56 different intervals (5 minutes up to 3 hours, 15 minutes up to 3-8 hours). Thus, the total number of recordable cases is 31 × 125 × 288 × 56 = 62,496,000.

In addition, the VSI system related to the KB PS code method of the above type is shown as shown in FIG.

Here, the microcomputer 31 for controlling the VSI system, the servo circuit 32 for driving control of the motor on the system deck side, the remote control unit 33a and the set side wirelessly connected to the remote control transmitter 33c The timer circuit 33 to which the key part 33b is connected, the audio circuit 35 which processes a voice signal in a system, etc. are provided.

In addition, the system includes a video circuit 37 for providing a recording signal to the tape side or processing a reproduction video signal from an RF signal provided from the tuner and the IF unit 38, and an audio signal during double speed reproduction on the system deck side. DMS (36) to control to provide a steady state, the KPS (34) to decode the KPS data, the tuner to tune the signal received from the antenna and generate a signal of intermediate frequency And an I F unit 38, a power circuit 39 for supplying a system power supply, and the like.

In addition, the conventional system of the reservation recording method using KBP data in such a system is introduced in Korean Patent Laid-Open Publication No. 1305 (Publication No. 94-16194).

In this case, when the user sees a program identifier written on a newspaper, etc., and inputs as reserved recording data, the system checks whether the scheduled recording is set as shown in FIG. After that, the identification code is extracted to proceed with or end the reservation recording based on the start time, length, title, etc. of the program provided by the KBP signal data.

However, in such a conventional system, data such as the start time, length, and title of a program are transmitted to a broadcast signal, but the remaining time data of the program is not handled, which limits the various control operations of such a system.

An object of the present invention is to implement the convenience of using such a system by performing one-touch automatic recording until the end of a predetermined program by using the remaining time data sent from the broadcast system to improve the above problems.

The present invention provides a video processing unit for processing the received video signal VI as a recording signal or a reproduction system signal, and the vertical blanking interval of the composite synchronization signal from the output of the video processing unit so as to achieve the object of the above example. Detects the remaining time data for and records the input of the recording key, and automatically controls the deck unit during the remaining time, and performs the recording operation, and generates the remaining time data signal under the control of the micro computer, and generates a video signal and It is characterized by the VSI system having the remaining recording function of the configuration that includes the OSD unit to be synthesized, the key input unit, and the deck unit of the recording drive operation.

Here, a video processor 11 generating and processing a video signal in a TV broadcasting system, and a microcomputer 12 receiving a composite synchronization signal CS provided from the video processor 11 and controlling time data in a vertical synchronization section. And a level adjuster 13 that receives the time data signal of the microcomputer 13 and adjusts it to an appropriate magnitude, and outputs the video signal VS and the level adjuster 13 of the video processor 11 to the microcomputer. And an output changeover switch 14 for selectively connecting to the rear end under the control of the computer 13.

The system circuit block of the present invention related to the remaining time data of a predetermined program transmitted from the remaining time insertion circuit of the TV broadcast is shown in FIG. 5.

Here, the video processing unit 41 processing the received video signal VI as a recording signal or a reproduction system signal, and the vertical blanking section of the composite synchronization signal are examined from the output of the video processing unit 41, and the remaining time for the program. When the data is detected and the recording key is input, the microcomputer 42 in a control operation for automatically controlling the deck unit 45 for the remaining time and performing the recording operation, and the remaining time data signal under the control of the microcomputer 42. The OSD unit 43 for generating and synthesizing the video signal with the video signal, the key input unit 44, the deck unit 45 for the recording drive operation, and the like are included.

According to the present invention of FIG. 4, when the video input signal VI generated from the broadcast camera signal is input to the video processor 11 of the remaining time insertion circuit, the video processor 11 processes and outputs the video input signal. It is sent to the changeover switch 14.

In addition, when the composite synchronization signal output from the video processor 11 is input to the microcomputer 12, the microcomputer 12 detects a vertical blanking section of the composite synchronization signal and counts the current time. Is adjusted to an appropriate level in the level adjusting section 13 and then provided to the output switching switch section 14.

When the total time for the predetermined program of the microcomputer 12 is 55 minutes, the output switching switch unit 14 performs time counting operation up / down from the total time to send the time data to the level adjusting unit 13. The output switching switch section 14 shows that the microcomputer 12 has a total time of 55 minutes / remaining time 55 seconds → total time 55 minutes / remaining time 54 seconds → total time 55 minutes / remaining time by 1 field in the vertical blanking interval. 53 seconds → Total time 55 minutes / Remaining time 52 seconds → Total time 55 minutes / Remaining time 51 seconds → Total time 55 minutes / Remaining time 50 seconds → ............ → Total time 55 minutes / Remaining time The data is loaded in 00 minutes.

On the other hand, in the VSI or the like receiving the broadcast system signal as shown in FIG. 5, after the video signal is filtered by the video processor 41, the remaining time data of the vertical synchronization section is provided to the microcomputer 42.
