The present invention relates to a recording medium and a data broadcasting method in which a data broadcasting application is stored. In particular, the present invention relates to a recording medium storing a data broadcasting application capable of realizing data broadcasting according to various driving environments, and a data broadcasting method.

Digital conversion of analog broadcasting is taking place all over the world. In line with these trends, the Korea Broadcasting Commission has set the ratio of compulsory broadcast programs for terrestrial broadcasters to increase the ratios every year until 2010, and mandated the broadcast of digital programs after 2010. As a result, not only terrestrial broadcasters but also cable broadcasters are switching to digital broadcast systems, and the number of terrestrial broadcasters' digital broadcast programs is increasing day by day. In addition, with the activation of digital broadcasting, data broadcasting, which is emerging as a profit model of digital broadcasting, is also expected to be activated.

According to the classification of the Broadcasting Committee, data broadcasting is a broadcasting service that transmits video and audio based on data (referring to letters, numbers, figures, diagrams, images, and other information systems), and various additional data. This program is defined as a broadcast that allows viewers to selectively view by interworking with the program or independently.

In addition, in general, data broadcasting may be referred to as providing information, weather, securities, and news together with a broadcasting program through a broadcasting network, and also includes broadcasting for providing information and electronic commerce (EC) through the Internet. . Such data broadcasting has the function of creating new high value-added new industries such as services, devices, and contents as well as functioning as a new information infrastructure for general users.

These data broadcasts can be classified in various ways. The Broadcasting Commission categorizes data broadcasts into dedicated data broadcasts and auxiliary data broadcasts.

Dedicated data broadcasting provides only data such as text, audio, and graphics through separate channels without providing broadcast programs. Currently, news letters, miscellaneous expenses, internet access, home banking, e-mail, games, portal channel services Etc.

Auxiliary data broadcasting is classified as linked data broadcasting and independent data broadcasting by auxiliary data broadcasting while serving a broadcasting program through one channel. The linked data broadcasting is broadcasting data related to an audio / video program being broadcasted. For example, when a sports program is broadcast, broadcasting data such as sports player information related to the sports program is broadcast. Stand-alone data broadcasting is broadcasting data that is not related to the audio / video program being broadcasted. For example, when a sports program is broadcast, broadcasting data such as weather and securities that are not related to the sports program is broadcast.

On the other hand, there are a variety of media such as cable TV, satellite broadcasting, and IPTV (Internet Protocol TeleVision), which is currently preparing to launch a business, but the terrestrial program has only the goal of securing rich contents for channel selection. Retransmission is the main content. According to Nielsen Media Research's 2004 monthly cable TV ratings report, cable paying subscribers accounted for 64.7% of terrestrial broadcasters in March 2004, the lowest in 2004. Monthly occupancy also accounted for 61.4%, an average share of more than 60%. Considering that the survey sets only 6 channels such as KBS1, KBS2, MBC, SBS, iTV, and EBS, terrestrial broadcasting channels include terrestrial broadcasting contents such as MBC Dramanet. It can be seen that the influence of the content is absolute.

As the terrestrial program broadcast rate is high in pay broadcasts, the broadcast of terrestrial digital broadcast programs, especially data broadcast programs, becomes a problem. As terrestrial broadcasting follows the American Advanced Television System Committee (ATSC) scheme, cable broadcasting follows the OpenCable scheme, and satellite broadcasting follows the DVB (Digital Video Broadcasting) scheme, domestic digital broadcasting is digital in different ways. We broadcast. As a result, terrestrial waves transmit data broadcast using ACAP (Advanced Common Application Platform), cable broadcasting OCAP (Open Cable Application Platform), and satellite broadcasting DVB-MHP (Digital Video Broadcasting-Multimedia Home Platform). In addition, IPTV, which will be introduced later, will perform data broadcasting using another standard.

In broadcasting digital broadcasting according to the global trend toward digital broadcasting and consumer's desire, pay broadcasting platform provides auxiliary data broadcasting which provides auxiliary data to data broadcasting which is the main revenue model of digital broadcasting, especially A / V that is aired. In case of retransmission through, there are many problems due to differences in screen specifications and differences in transmission methods.

For example, digital broadcasting currently transmitted by terrestrial broadcasting transmits HD (High Definition) grade video, whereas pay broadcasting such as cable and satellite broadcasting transmits SD (Standard Definition) grade video. Of course, cable broadcasting is also preparing for HD broadcasting, but due to the domestic broadcasting environment is still applying a separate digital broadcasting standard.

Here, the HD (High Definition) class and the SD (Standard Definition) class are digital TV standards, which are distinguished according to picture quality and video standards. HD is an image standard of 16 to 9, and the number of pixels determining the quality of digital TVs is 1920x1080i or 1024x720p, and provides high-quality images of up to 2 million pixels or more. In contrast, SD has a 4: 3 standard, and the number of pixels is 720x480p or 720x480i or 640x480i or 640x480p, which provides about 350,000 pixels of resolution. SD has higher quality than analog, but its quality and clarity are much lower than HD.

As such, the domestic broadcasting environment is mixed with HD and SD screen standards. However, HD class, which requires high definition and a lot of bandwidth, and SD class, which have lower image quality than HD class, but have a small bandwidth requirement, are difficult to integrate into a standard due to their characteristics.

Auxiliary data broadcasting is reproduced on the screen along with the A / V data broadcasting application. However, due to the difference between HD and SD screen standards, fonts lose their proportions and become distorted, and graphic images may be broken by distortions such as enlargement or reduction of original images. In addition, it is not clear who is responsible for terrestrial or distortion of terrestrial data broadcasting programs transmitted through the pay broadcasting platform or whether the pay broadcasting platform is responsible. Participation in possible quizzes, voting, etc. brings security and personal authentication issues to reflect the viewer's participation.

However, in order to prevent such a problem, if the content for SD is separately produced in duplicate, a huge amount of content and application production costs are incurred, and additional costs are required to match content and applications for each retransmission platform, and retransmission must be considered in design and coding. This leads to an increase in costs.

An object of the present invention is to provide a recording medium storing a data broadcasting application capable of realizing data broadcasting according to various driving environments.
