Digital broadcast recording device

A digital broadcast recording method for receiving a digital broadcast and storing program information of the digital broadcast, comprising:

• receiving one physical channel of the digital broadcast, the one physical channel including a specific number of two or more sub-channels;
• displaying a first setting screen with a guidance information and input buttons, the guidance information prompting a user to input a first operation input indicating whether or not the program information corresponding to the one physical channel is entirely recorded;
• receiving the first operation input from the user through selection of the input buttons of the first setting screen by the user;
• setting a recording condition based on the first operation input;
• displaying a second setting screen prompting the user to input a second operation input indicating which of the program information corresponding to a subset of the specific number of the sub-channels included in the one physical channel is recorded in response to receiving the first operation input indicating that the program information corresponding to the one physical channel is not entirely recorded through selection of one of the input buttons of the first setting screen by the user, the second setting screen being different from the first setting screen;
• receiving the second operation input from the user;
• setting a sub-channel number corresponding to the subset of the specific number of the sub-channels based on the second operation input in a scheduled recording memory;
• extracting the program information corresponding to the subset of the specific number of the sub-channels from the program information corresponding to the one physical channel of the digital broadcast upon setting the recording condition to record the program information corresponding to the subset of the specific number of the sub-channels;
• determining whether the sub-channel number corresponding to the subset of the specific number of the sub-channels set based on the second operation input is stored in the scheduled recording memory;
• recording the program information corresponding to the one physical channel of the digital broadcast based on a physical channel number stored in the scheduled recording memory in response to determining that the sub-channel number corresponding to the subset of the specific number of the sub-channels set based on the second operation input is not stored in the scheduled recording memory;
• and
• recording the program information corresponding to the subset of the specific number of the sub-channels in response to determining that a the sub-channel number corresponding to the subset of the specific number of the sub-channels set based on the second operation input is stored in the scheduled recording memory.
