Embodiment Construction

[0010] The present invention utilizes the value determined according to the operation of the above-mentioned encoding device, that is, it can convert the data into a signal of NRZI form, and the encoding method of the DVD device is characterized by the following steps: appending and combining the data stored on the memory A step of outputting control data and an error detection method; a step of encoding the outputted data; a step of correcting the above error detection method; a step of adding error correction data for correcting an error in the data; converting a signal of the data A step of. That is, it is selectively encoded according to the kind of data. In addition, the above encoding has the following characteristics: store the data in the reference encoding area, and encode part or all of the data according to whether the data is located in the start sector or not. That is, the data is stored in the reference encoding area, and when the data is located in the first se...

Abstract

The invention discloses a DVD (digital video disk) coding memory device, relating to a coding device of DVD equipment and a method thereof and providing a coding device of DVD equipment and a method thereof. A coding process is reduced to one step and the processes of reading and storing data from a memory is reduced, thereby reducing the use level of the memory and bandwidth. The device comprises a control data additional device used for adding control data to data stored on a memory, an error detecting method additional device of an error detecting method for detecting whether stored data can be normally read or not, a coding device for selectively coding according data varieties, an error detecting method correcting device for correcting the error detecting method, an error correcting data additional device for correcting errors of the data, and a modulating device for transforming data signals.

Description

technical field [0001] The present invention relates to an encoding device and method for DVD equipment. Background technique [0002] At present, DVD memory is rapidly replacing CD memory. Compared with CD memory, DVD memory can store a large amount of data equivalent to about 7 times, which is its advantage. Traditional DVD memory is made up of following several parts: generate the main frame of the data (sector data) stored on the DVD memory; The sector data generated by above-mentioned main frame and the intermediate data that encoding device generates in encoding process are stored, until A memory that stores coded data until the data at the end of the code is input to the storage pulse generator; a coder that reads sector data in the above memory and decodes it into data that can be stored on a DVD memory ; Convert the signal output by the above-mentioned coding device into a storage pulse generating device that can be stored in a pulse form on the DVD device; the abo...
