发明名称 Apparatus and method for recording multimedia data with high efficiency
摘要 An apparatus and method for recording multimedia data is disclosed. The apparatus and method employ a receiving unit for receiving compressed multimedia signal, a decoder unit for decoding the multimedia signal to convert it into a data stream having a predetermined format, a data compression unit for reducing the amount of data in the data stream by a certain amount and encoding it, a compression select unit for setting a compressibility of the data compression unit, and a storage unit for storing the encoded data. In accordance with the apparatus for recording the multimedia data, in the case where there is no need to record the video data with high quality, it is possible to increase the recording time of the multimedia data by reducing the data amount of the video signal using a variety of compression methods when the multimedia data is recorded in a storage device.
