Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below, exemplified with reference to the accompanying drawings, wherein like reference numerals designate like parts throughout. The embodiments are described below to explain the present invention by referring to the figures.

[0030] FIG. 2 is a block diagram of a digital recording / reproducing apparatus with a time shift function according to an embodiment of the present invention.

[0031] Referring to FIG. 2, the digital recording / reproducing apparatus 100 includes a video data encoder 110, a controller 130, a first data storage medium 150, a video data decoder 170, and a second data storage medium 200 removable according to a user's selection.

[0032] The video encoder 110 compresses received video data using a predetermined compression method, and outputs the compressed video data to the controller 130 .

[0033] The controller 130 receives compressed video data from the video data encoder 110 . T...

Abstract

A digital recording / reproducing apparatus including a first data storage medium with a timeshift function; and a controller, which records received compressed data on both the first data storage medium and a second data storage medium without a timeshift function if a recording command that requires data to be recorded on the second data storage medium is received, and reads data recorded on the first data storage medium for data reproduction if a reproduction command for data being recorded is received. Therefore, it is possible to include a timeshift function to reproduce recorded data and to output the reproduced data to a user while recording data according to the user's command, even when the digital recording / reproducing apparatus records data on a data storage medium without the timeshift function.

Description

[0001] Cross-Referenced Related Applications [0002] This application claims priority from Korean Patent Application No. 2003-20739 filed with the Korean Intellectual Property Office on April 2, 2003, the entire disclosure of which is incorporated herein. technical field [0003] The present invention relates to a digital recording / reproducing device with a time shift function and a method for the device. Background technique [0004] The development of semiconductor and data storage medium technologies has led to increased use of digital type data recording / reproducing devices to replace conventional analog type data recording / reproducing devices. [0005] A digital type data recording / reproducing apparatus compresses data such as an analog or digital television signal in a digital format, stores the compressed data, and then decodes the stored data to reproduce the data on a display device such as a television or a monitor. data. [0006] Recently, various digital video...
