Abstract:
1. A broadcast system comprising: a transmitting unit comprising transmitting unit link areas, the transmitting unit performing: a browserless receiving terminal; an encoder performing: a receiving unit comprising a decoder, said receiving unit performing: an application server in the transmitting unit link areas converting a web page transmitted from the Internet into video data of an image and sends the video data, said application server providing links to the image on the basis of a plurality of image links provided to the web page, wherein: upon activation of a web browser on the application server, the video data of the image is sent to an MPEG2 encoder of a video server and compressed, whereupon links are set at selected areas of the web page and contour coordinate data of selected link areas are extracted by the application server, each selected link area from said selected link areas being of rectangular shape and described using coordinates of the four vertexes of said each selected area and each selected area is defined in an HTML file, and coordinate data of said each selected area is extracted from the HTML file; the link areas are linked to other web pages; while extracting coordinate data concerning the selected link areas, the application server generating link information including addresses of web pages linked to the selected link areas, link information containing coordinate data of all the link areas within the web page and addresses of web pages linked to these areas are generated on a basis of coordinate data contained in the HTML file, and sent to a multiplexer of the video server; and the browserless receiving terminal to output the video data of the image to a television; and a microprocessor unit (MPU) of a set top box (STB) establishing an association between the link information of the video data of the image and a position of a cursor in the video data of the image, said browserless receiving terminal comparing a position coordinate of the cursor with coordinates of points included in the selected link areas, when the MPU determines that the position coordinate of the cursor is positioned in any of the selected link areas, the MPU informs a user about changing an appearance of the cursor, and a desired link is selected by moving the cursor using an input device, wherein when the application server sends the video data of the image, the application server extracts the link areas on the basis of the image links provided to the web page, and generates link information including web addresses linked to the image links provided to the web page and data defining the link areas on the image, and combines the link information and the video data of the image compressed in accordance with the MPEG-2 standard with other MPEG-2 data, EPG data in the multiplexer to form multiplexed data, the multiplexed data then transmitted from a transmitter to a demultiplexer; the demultiplexer sending link information to the MPU while sending video data and audio data of the image to the MPGE-2 decoder; outputting means for outputting video data and audio data decoded by the decoder to a television in the same manner as conventional television; and displaying the image and the cursor on a television screen, and to manipulate the cursor using an input device, wherein the video image is reproduced without a need to use a web browser, a conventional high-speed MPU, or a high-capacity memory.
