Abstract

Information relating to print contents is presented to the user in an easily understandable manner. A demultiplexer separates picture data, speech data and other data from received data. Such data include EPG data, data broadcast data, print contents data and supplementary information on the print contents data. A data stream process unit decodes the supplementary information on the print contents data and the print contents data. An image construction unit constructs an image signal of an image frame, providing a list display of transmission schedule and supplementary information of the print contents. The image signal is supplied through a display controller to an image display unit and displayed as an image.

Claims

1. A TV apparatus connectable to a printer, said TV apparatus comprising:

a tuner unit that receives a broadcast signal including electronic program guide (EPG) data, printable contents data, and supplementary information data relating to the printable contents data;

a control unit that generates print contents guide (PCG) data according to the supplementary information data; and

a display control unit that controls a display device to selectively display an EPG image based on the EPG data and a PCG image based on the PCG data, the EPG image comprising a program broadcasting schedule,

wherein the PCG image has cells disposed in an area defined by a time-axis and a channel-axis at positions corresponding to channels and broadcast times, and the PCG image displays printable contents information indicating in each cell whether or not printable contents are broadcasted, on the basis of the supplementary information data,

wherein the printable contents information is a content title of printable contents if the printable contents are broadcasted, while the printable contents information is a message indicating the absence of printable contents if the printable contents are not broadcasted.

2. A TV apparatus according to claim 1, wherein the display control unit controls the display device to display a preview image of the printable contents selected by the user on the PCG image, and

wherein the preview image comprises a plurality of thumbnail images based on image data obtained from the printable contents data.

3. A TV apparatus according to claim 1, wherein the supplementary information includes content details, printable time period, and print fee information of the selected printable contents.

4. A method for processing data in a TV apparatus, the method comprising the steps of:

receiving a broadcast signal including electronic program guide (EPG) data, printable contents data, and supplementary information data relating to the printable contents data;

generating print contents guide (PCG) data according to the supplementary information data; and

controlling a display device to selectively display an EPG image based on the EPG data and a PCG image based on the PCG data, the EPG image comprising a program broadcasting schedule,

wherein the PCG image has cells disposed in an area defined by a time-axis and a channel-axis at positions corresponding to channels and broadcast times, and the PCG image displays printable contents information in each cell indicating whether or not printable contents are broadcasted, on the basis of the supplementary information data,

wherein the printable contents information is a content title of printable contents if the printable contents are broadcasted, while the printable contents information is a message indicating the absence of printable contents if the printable contents are not broadcasted.
