Abstract

The present invention relates to a reservation recording device for a VC combined VCP and a control method thereof. In the conventional technology, a VCP cannot receive a tuner signal, and thus the recording function is limited to a line recording function (broadcasting). There is no additional cost because it is impossible to implement various functions related to broadcast signal reception, and if you want to record broadcast signals, you need to purchase a separate VRL with a tuner. Problems; The VCR may implement various functions related to broadcast signal reception with a built-in tuner unit, but the role of the tuner unit, which occupies a large part of the cost, is used only for some functions such as reservation recording, thereby reducing efficiency.

Therefore, the present invention was devised to solve the above-described problems, and by using a common part of the tuner part built into the TV and the tuner part built into the TV, it is possible to perform a reservation recording function without using the tuner part. By providing an apparatus and a method, various functions related to broadcast signal reception can be implemented. Therefore, if a user wants to record a broadcast signal, there is no additional cost incurred by separately purchasing a TV with a tuner. By using the common parts of the tuner part and the tuner part embedded in the V-CAL, the V-Caler's tuner part is not used, thereby reducing the cost and providing an ultra-low cost V-AL.

Description

VCD Combined Recording System and its Control Method

The present invention relates to a reservation recording apparatus for a V-Cal combined VPC and a control method thereof. In particular, a video cassette player (VCP) without a tuner unit for receiving a broadcast signal (hereinafter referred to as "VC") The present invention relates to a reservation signal recording device for a VRC combined VPC which can perform a reservation recording operation like a VCR even without a tuner recording function. .

1 is a block diagram showing the configuration of a conventional VPC, as shown in the connecting portion 10 for connecting the VPC and the external device; A video processor (11) for RF signal processing to separate and low-pass the input video signal into luminance and color signals for recording on a magnetic tape; An audio processor (12) for processing the input audio signal to be frequency-modulated (FM) and recorded on a magnetic tape; A pre-amplifier section (13) for recording or reproducing each RF signal modulated by the video and audio processing section (11) (12) on a magnetic tape; An external device 14 serving as a signal source during line input recording; It consists of a microcomputer 15 which controls the overall operation of recording and reproducing video and audio signals.

FIG. 2 is a block diagram showing a conventional V-Cal. As shown therein, the video and audio processing unit 11 and 12, the pre-amplifying unit 13 and the external device 14, shown in FIG. A tuner unit 20 configured to receive an over-the-air signal input from an antenna ANT and output an RF signal of a channel selected by a user in a VPC composed of the microcomputer 15; The RF signal of the tuned channel tuned by the tuner 20 is converted to an intermediate frequency (IF) signal (low-conversion) to detect a signal to process each video and audio signal. An intermediate frequency unit 21; A video and audio detector (22) (23) for detecting and finally outputting each audio and video signal (SIF, VIF) separated from the intermediate frequency unit (21); The microcomputer 15 recognizes VPS / PDC data carried on a Video Program System (hereinafter referred to as "VPS") / Program Delivery Control (hereinafter referred to as "PDC") channel. In addition to the VPS / PDC slicer 24 for extracting the information of the VPS / PDC channel currently received in the configuration of the conventional device as described above will be described as follows.

In the VCP, a recording function receives video and audio signals of a separate external device through the connection unit 10 as shown in FIG. 1, and then receives the RF signals from the video and audio processing units 11 and 12, respectively. Each signal modulated by the pre-amp section 13 under the control of the microcomputer 15 during the processing, the FM and the amplitude modulation (AM) recording, is recorded on the magnetic tape.

The recording function in the VCR is processed by the tuner unit 20 and the intermediate frequency unit 21 that receive the broadcast signal at the frequency of the channel selected by the user. The broadcast signal is the intermediate frequency unit 21. ) Are separated into video and audio signals, and are detected by the video and audio detectors 22 and 23 and input to the pre-amplifier 13 through the video and audio processor 11 and 12, respectively. Also, in case of a scheduled recording of a Video Program System (hereinafter referred to as "VPS") / Program Delivery Control (hereinafter referred to as "PDC"), a tuner unit mounted on a received VPS / PDC channel ( The video signal of 20) is recognized by the VPS / PDC slicer 24 to confirm the VPS / PDC code, and then a reserved recording function is performed.

As described above, since the VCP cannot receive the tuner signal, the recording function is limited to the line recording function (it cannot have the reservation recording function of the broadcast signal), thereby receiving the broadcast signal. It is not possible to implement various functions related to the problem, and if the user wants to record broadcast signals, there is a problem in that an additional cost occurs because a tuner is required to purchase a separate V-Cal; The VCR may implement various functions related to broadcast signal reception with a built-in tuner unit, but the role of the tuner unit, which occupies a large part of the cost, is used only for some functions such as reservation recording, thereby reducing efficiency.

Therefore, the present invention was devised to solve the above-described problems, and by using a common part of the tuner part built into the TV and the tuner part built into the TV, it is possible to perform a reservation recording function without using the tuner part. It is an object of the present invention to provide an apparatus and method.
