DEVICE FOR HIGH SPEED SEARCH STANDARD DEFINITION VIDEO CASSETTE RECORDER

摘要

1. The technical field to which the invention described in the claims belongs:;The present invention relates to the video cassette recorder.;2. The technical problem to be solved by the invention:;The present invention provides a high-speed search apparatus for a video cassette recorder capable of compressing a scene photographed in a photo mode in a memory added to a tape at the time of recording to reduce the amount of data and to record an image in a cassette memory section.;3. Summary of the solution of the invention:;According to an embodiment of the present invention, a first data compression processing unit which receives data of a predetermined bit unit from an external system and compresses the data to reduce the amount of data to a predetermined amount is connected to the first data compression processing unit. An error correction code inserting section for inserting a?, A modulating section connected to said error correction code inserting section, and modulating said encoded data to match a recording form; and a recording signal connected to said modulation section for amplifying said modulated data; An amplifying unit, a recording medium connected to the recording signal amplifying unit to record the amplified data, a reproducing signal amplifying unit for amplifying the recorded data connected to the recording medium, and amplifying the reproducing signal. A demodulator for converting data modulated by being connected to the data into data of an original form, and connected to the demodulator to A video cassette recorder including an error correction and decoding unit for error correction and decoding through an entered error correction code, and a first data extension unit connected to the error correction and decoding unit for decompressing compressed data into original data. A fast search apparatus for an order, comprising: a second data compression processing unit for reducing the input data to a predetermined amount in bits and a second data compression processing unit for storing the compressed data in a memory in a cassette; A first cassette memory section, a second cassette memory section authoring the previous data, a second data decompression section connected to the second cassette memory section for decompressing the data stored in the memory, respectively A connection between a second data compression processing section and a second data extending section and the first cassette memory section and the second cassette memory section And it characterized by a microcomputer unit for controlling the storage and the height of the control data.;4. Important uses of the invention:;The present invention is suitably used for video cassette recorders.
