Abstract: There is disclosed a method of skipping unrecorded area during playback in order to minimize an interruption time upon playing back a recorded program in a tape drive. The method is performed while playing back a record medium, such that an area with no videos and audios is played back at a high speed and an area with videos and audios is played back at a normal speed, resulting in minimized time for playing back unrecorded areas, thus yielding another advantage in that an audience is kept from being bored and, furthermore, power is saved by automatically turning the power-off when the record medium playback is completed.

Abstract: An automatic (auto) tape searching method which searches the required tape portion fast and automatically by repeating a sequence of operational procedures. The auto tape searching method comprises: a first stage which initializes the port of a microcomputer and the content of a RAM (random access memory), sets the initial values, and controls interrupts at a power-on reset of a video tape recording system; a second stage which checks key input and, for auto random search (ARS) key, performs the auto random search function; a third stage which performs mode checking and, if a present mode needs to accompany the mechanism operation, controls the present mode; and a fourth stage which switches the mode and checks the sensor and an emergency state to make the system in stable condition.

Abstract: A screen encore method capable of displaying again (encore) a block of pictures designated by a user or a last picture with a single key by software control, without adding hardware, so that the inventive system is highly improved both in its function and quality. The inventive system for embodying the method includes: a micom for controlling basic functions of the Video Tape Recorder (VTR) system and functions of the inventive subject; a delay device for indicating to the user the status of the VTR system under the control of the micom; a mechanism for implementing the insertion/ejection of video tapes and tape loading/unloading by the control signals coming from the micom; a video and audio signal controller for controlling video and audio signals under the control of the micom; a remote control receiver for receiving remote control signals from a remote control set to filter and amplify the signals, thereby to transmit them the micom; a sensor for sensing the present operational location of the mechanism and the status of the beginning/end of tapes to transfer the sensed data to the micom; and a keyboard, as a key input running the VTR's functions, for inputting function key and command key to the micom including an encore key.
