Title: Video tape recorder
Inventor: KIM SANG-IL
IPC: G11B27/10
Filed: 1992-05-13
Granted: 1994-12-23
Abstract: The circuit is for recording the audio separately when reserved recording. When the reserved time set to a system controller (4), the image and sound signals detected by a tuner (1) are processed in an image (2) and a first audio (2) processors. The image and audio signals are recorded on the video tape by a video deck (7), but the audio signal is processed in a second audio processor separately and recorded on the audio tape by an audio deck (10).

Title: Frequency characteristic automatic switching circuit using noise level detection
Inventor: PARK SOO-WON
IPC: H04N5/21
Filed: 1992-10-07
Granted: 1997-03-27
Abstract: The frequency characteristic automatic switching circuit through a noise level detection comprises a band trap circuit part(1,2,3) constructed so as to pass a luminous signal(hereinafter, referred to as 'Y signal') separated from an image signal through a trap of a designed specific frequency, limit its resolution and output it, and connected in parallel so as to switch in resolution the Y signal; a high pass filtering part(4) for receiving the Y signal; a de-multiplying circuit part(5) for receiving an output passed through the high pass filtering part(4); a control switching voltage generating circuit part(6) for receiving an output through the de-multiplying circuit part(5) and selectly controlling the trap; and a switching part(S1,S2,S3) connected to each of the band trap circuit parts(1,2,3), thereby lessening an inconvenience that a user directly manipulates a switch for a switching operation whenever necessary.
