The present invention relates to a program transmission control method of an Internet television that can be used.

Recently, the use of the Internet service to provide a variety of communication information for a specific subscriber terminal through the Internet Service Provider (ISP) on the information communication network has been spreading, the communication connection of the Internet service is a TCP / IP method It can be executed by a web browser program such as mosaic or netscape on a personal computer (PC) or a workstation equipped with a modem.

At this time, the Internet service not only transmits and receives files by the former Goper or FTP (File Transfer Protocol) service, but also forms a HTML (Hyper Text Makeup Language) document by HTTP protocol by connecting to the Internet from the ISP side. Web (WWW) information as multimedia information reproduced together with predetermined image information (e.g., JPEG, GIF, or PCX format) or audio information (e.g., Real-Audio). The hypertext function employed in an HTML document used as a language defining such web information is widely used, and the hypertext mark designates a portion where a hypertext mark is displayed, and another web is controlled by a mouse click or an enter key operation. It allows for connection with information.

On the other hand, in the television, text information and image information included in web information provided by a predetermined ISP that is provided with a dedicated modem for Internet service, which was limited to a personal computer or a workstation-class computer. For example, Internet televisions with Internet service functions for converting them into video signals of a television video standard such as NTSC system and playing them through a CRT screen have been developed and commercialized.

In such an Internet television, a web browser program stored in a nonvolatile memory such as a ROM is started to receive web information provided from an ISP through a modem to process data through a microprocessor. The program and related software programs are operated to enable the recognition and display of HTML document files of the web information, and the execution commands in the communication information are transmitted to the microcomputer (Micom). The image information can be reproduced through a CRT screen while stored in a volatile memory such as a RAM.

However, in such Internet televisions, when a dedicated web browser program is run to search a website for predetermined web information on the Internet, HTML of various MIME types (Multi-Purpose Internet Mail Extensions Types) for each web information is various. In order to recognize and save or display the document file, the user must obtain a dedicated software program for recognition and display of the corresponding MIME type at that time, and store and use it in a nonvolatile memory such as a ROM. In the case where the user selectively downloads the relevant software program, it takes a long time to download the related software program, and thus there is a disadvantage in that an efficient search of the Internet information cannot be performed.
