Digital broadcast receiving apparatus and method of display video data in electronic program guide

A digital broadcast receiving apparatus comprising:

• a receiver to receive electronic program guide (EPG) data containing character data and optionally video data associated with TV programs;
• a memory to temporary store the EPG data received by the receiver;
• and
• a display controller to control displaying of an EPG with the EPG data such that, based on the EPG data stored in the memory, the display controller determines, per TV program, whether the video data is contained in the EPG data in addition to the character data and controls the EPG displaying so that the character data is only displayed when it is determined that the video data is not contained in the EPG data whereas, when it is determined that the video data is contained in the EPG data, the display controller determines whether a specific size of a minimum video-data displaying zone remains in an EPG-data displaying area in the EPG for each TV program after displaying the character data in the EPG-data displaying area per TV program and controls the EPG displaying so that the character data is only displayed when it is determined that the minimum video-data displaying zone does not remain whereas, when it is determined that the minimum video-data displaying zone remains, the display controller controls the EPG displaying so that the video data is displayed in the minimum video-data displaying zone, in addition to displaying the character data in the EPG-data displaying area.

A method of displaying electronic program guide (EPG) data on a screen, the EPG data containing character data and optionally video data associated with TV programs, comprising the steps of:

• receiving the EPG data and temporary storing the EPG data in a memory;
• determining whether the EPG data contains the video data in addition to the character data for each TV program based on the EPG data stored in the memory;
• displaying an EPG with only the character data on the screen for each TV program when it is determined that the EPG data does not contain the video data;
• when it is determined that the EPG data contains the video data, determining whether a specific size of a minimum video-data displaying zone remains in an EPG-data displaying area in the EPG for each TV program after displaying the character data in the EPG-data displaying area per TV program;
• displaying only the character data in the EPG when it is determined that the minimum video-data displaying zone does not remain;
• and
• displaying the video data in the minimum video-data displaying zone in addition to displaying the character data in the EPG-data displaying area when it is determined that the minimum video-data displaying zone remains.

A method of displaying electronic program guide (EPG) data on a screen, the EPG data containing character data and video data associated with TV programs, comprising the steps of:

• receiving the EPG data and temporary storing the EPG data in a memory;
• scrolling the EPG on the screen at a fixed scrolling time interval based on the EPG data stored in the memory;
• and
• while scrolling, determining whether a displaying width in the EPG in a direction of scrolling is smaller than a reference value per. TV program and erasing the video data from the memory for a specific TV program or specific TV programs when it is determined that the displaying width in the EPG in the direction of scrolling is smaller than the reference value for the specific TV program or TV programs.
