According to an aspect of the present invention, there is provided a method of setting a recording bit rate for a broadcast program, the method comprising: storing and storing broadcast program identification information and a recording bit rate; Searching and confirming any one of the stored recording bit rates stored in association with identification information of the broadcast program for which recording is requested; And recording the broadcast program data at the confirmed recording bit rate.

Hereinafter, a preferred embodiment of a recording bit rate setting method for each broadcast program according to the present invention will be described in detail with reference to the accompanying drawings.

First, the recording bit rate setting method for each broadcast program according to the present invention can be applied to an optical disc recorder, for example, a DVD recorder or the like configured as described above with reference to FIG. 1. Upon request, the OSD generation unit 15 is controlled to display an OSD menu image of a program-recorded bit rate setting mode newly added by the present invention.

For example, as shown in FIG. 2, in the OSD menu image of the recording bit rate setting mode for each program, a first menu item for allowing a user to select a program type and a recording bit for the program. A second menu item may be output displayed to allow selection of a rate.

Meanwhile, various types of broadcast programs such as sports, movies, advertisements, etc. may be outputted and displayed on the first menu item in a list form, and in the second menu item, maximum recording bit rate, general recording bit rate, minimum recording Various recording bit rates, such as bit rates, may be output displayed in the form of a list.

In addition, in the microcomputer 13, when a user selects a program type of any one of the first menu items and a recording bit rate of any one of the second menu items, and then clicks a select completion button. For example, after selecting and specifying the 'movie' and 'maximum recording bit rate' respectively, when the selection completion button is clicked, the program type and the recording bit rate are stored in the memory 14 in association with each other. ,

As the memory 14, a nonvolatile memory such as a flash memory or an EEPROM may be used. The memory 14 includes a program type selected by a user as illustrated in FIG. 3. In addition to storing (Program_Type) and Record Bit Rate in association with each other, a unique program ID (Program_ID) assigned in EPG information is additionally linked to identify the type of each broadcast program.
