Description

Television with delayed viewing

The present invention relates to a television having a function of delayed viewing. Particularly, when a user is unable to watch a television for a short time due to a telephone call or an outside visit, a part of the screen may include a broadcast screen before a certain time. The present invention relates to a television having a function of delayed viewing so that a viewer can efficiently watch the contents of all broadcasts.

The modern age is the age of mass media, and television has become a necessity for modern people, and the vast majority of people are getting various and important information through television, and spend a lot of leisure time watching entertainment programs and soap operas broadcast on television.

Therefore, broadcasts of particularly important contents or broadcast programs with a lot of interest are desired to be watched without missing a broadcast contents even for a short time.

However, the conventional television had to wait for re-broadcasting from the broadcasting station in order to replay the past broadcast contents. If it is an important broadcast, it is difficult to watch the video recording device by separately recording and reproducing the video tape. Recorded on videotape and later played back with video playback.

As described above, even though the recording and reproducing apparatus were recorded on the videotape, the recorded contents could not be immediately checked, and the recorded contents had to be checked after the broadcasting program was finished. The contents and progress of the broadcast could not be understood accurately.

In addition, it is difficult for a user to prepare for a quick and simple recording in a short time even when the user suddenly becomes unable to watch a television due to a quick move to answer a call while watching or an outside visit.

Therefore, in order to effectively solve the above drawbacks, the present invention allows a user to easily display a broadcast before a certain time on a part of the currently broadcast screen by pressing a button on a remote controller or a key input unit so that the user can wait for rebroadcast or record and play a video It is an object of the present invention to provide a television that allows a user to watch a broadcast before a certain time passed without the device and a video tape.

In order to achieve the above object, the present invention uses a key input unit or a remote control according to a user's selection or operation state of internal machines to control the overall operation according to the viewing of the television by the method or order already set in the built-in program memory. And a tuner that tunes a television broadcast signal corresponding to a channel to be watched among the various television broadcast signals received through the antenna, and amplifies and detects the television broadcast signal tuned by the tuner as an intermediate frequency signal of a constant frequency. An intermediate frequency amplifying unit for outputting the signal to be viewed through a monitor and a speaker, an image detecting unit for detecting an image signal amplified by the intermediate frequency amplifying unit, and an image signal output through the image detecting unit R color signal by signal processing A signal processor for outputting G color and B color signals, an A / D converter for converting signals passed through the signal processor from analog to digital, a memory for storing the digitally converted signals, and a signal stored in the memory A D / A converter that reads under the control of a processor and converts a digital signal back into an analog signal, and a PIP (Picture In Picture) driver that displays a signal converted to analog only through a part of the screen through the D / A converter, An on-screen display IC that receives a control signal of a data signal, a strobe signal, and a clock signal from a microprocessor of the microprocessor, and outputs an on-screen display signal for operation or an optional display; Signals received from R signal, G color signal and B color signal from signal processor, PIP driver and on-screen display IC After processing, the color demodulator outputs the luminance signal Y, the color difference signal RY, and BY, and receives the luminance signal Y, the color difference signal RY, and BY from the color demodulator. The CRT driver that displays the image on the monitor and the SMPS type power supply which is supplied to the microprocessor as the operating power by receiving the AC power from the outside through the power cord and dropping the voltage to rectify the delayed viewing function are performed. As a result, when a user watches television, the user can easily and easily display a broadcast before a predetermined time on a part of the screen currently being broadcast.
