TECHNICAL AND SYSTEM FOR LINK TYPED DATA-BROADCASTING SERVICE TRANSMITTING CAPTION DATA BY REAL TIME FROM CABLE TV HOME SHOPPING BROADCASTING TO DMC }

The present invention relates to a method and a system for providing a linked data broadcasting service for real-time interlocking subtitle data to a DMC in a cable TV home shopping broadcast, and to describe in detail the subtitle data displayed on a live shopping home screen. It generates through the generator and transmits to the DMC-data interlocking means in real time. The subtitle data is processed and reconstructed into linked data broadcasting contents linked to the home shopping broadcasting currently broadcasted and reflected in the data broadcasting application. The present invention relates to a method and a system for providing an interlocking data broadcasting service linked with a conventional cable TV home shopping broadcasting by being displayed on a TV screen of a client through a set top box.

Digital TV as a digital broadcasting media is a TV system that digitally processes all analog signals such as video, audio, and data, and then transmits them by digital transmission method. Most of all, it has the advantage that data can be transmitted in both directions away from the existing one-way broadcasting, so it supports interactive services such as internet, home shopping and VOD (Video on Demand) to realize the function of interactive TV. do.

Interactive TVs as a convergence form of broadcast and communication can provide various digital multimedia contents desired by a client through an interactive screen. In other words, it provides a receiver-centered service, not a provider-centered service, provides a variety of multimedia contents combining data, software, multimedia, etc. with video / sound-oriented contents that have been predominantly existing, and provides interactive services including simple information type services. In addition, it provides a differentiated service from the existing teletext and subtitle broadcasting.

As one of digital broadcasting, data broadcasting is a broadcasting system that adds various data while digitizing TV transmission method, unlike traditional analog TV, by using broadcaster's channel, and adds various functions such as text, still images, graphics, documents, and software. It is best suited to the current trend of convergence of broadcasting and communication in which a client transmits data by using a broadcasting medium and a client uses the information in a dedicated set-top box. Such digital broadcasting provides data related to the broadcasting program while transmitting the stand alone service and TV broadcasting program provided through an independent channel operated separately from the TV broadcasting depending on the independence of the existing TV broadcasting. It is classified as an enhanced service. In particular, the linked service is a new type of digital broadcasting in which data broadcasting is linked to an existing broadcasting program. If a button on the left side of the screen is pressed with a remote control while watching a broadcast, the broadcasting screen has a predetermined size to obtain various data information through the remaining screens. It can be.

The existing analog broadcasting environment is rapidly changing to the digital broadcasting environment all over the world. As the broadcasting environment has recently changed to a digital environment, satellite broadcasters are also planning to start digital satellite broadcasting, starting with digital main broadcasting of terrestrial TV broadcasting from the metropolitan area in the second half of this year. In Korea, digital broadcasting is imminent, and cable broadcasting, which has represented Korea's new media broadcasting since its launch in 1995, has also been recently focused on the industry.

As the broadcasting environment is transforming into a digital environment as described above, cable providers that occupy more than 70% of Korean TV viewers can digitally transmit programs provided by program providers to digital viewers in order to digitize existing cable broadcasting. It should be possible. To this end, additional facilities for producing, compressing and transmitting existing analog broadcasting programs to digital signals should be additionally provided, and set-top boxes capable of receiving digital broadcasting should be distributed to each home. Digital cable TV broadcasting is expected to begin as early as the end of this year.

However, it is true that the cable TV industry, which is smaller than the terrestrial broadcasters and satellite broadcasters, cannot afford the enormous cost of digital conversion. As a result, telecommunications and broadcasting companies and cable TV broadcasting companies (SOs) are working together to share the cost of digital conversion in the cable TV industry. Digital Media Center (DMC) was established to provide digital cable broadcasting and multimedia services. The digital media center (DMC, abbreviated as DMC) can be understood as a concept of a wide-area digital transmission center in which digital broadcasting equipment is concentrated. In other words, by dividing the whole country into several regions, one digital head end is established for each region, and the digital broadcasting equipment is concentrated here, thereby providing program providers (PP) and cable TV in each region. It serves as an intermediate point of connection between broadcasting stations (SOs), providing retransmission of PP programs, additional channel services (data broadcasting area, VOD, etc.), Internet-related services, and communication services such as VoIP.

From 2007, many operators are expected to start data broadcasting related services. Therefore, home shopping broadcasting companies should develop data broadcasting services utilizing the characteristics of home shopping to maximize sales.

However, the user environment of digital data broadcasting developed so far is mobile, T-banking, news, movie, music, SMS, GPS, ticketing, game, advertisement, and mail. It is only. In addition, although the user environment is configured to make the digital environment of the consumer useful, a user environment and a system of a type directly related to the sales of home shopping that is performed live are not developed.

Meanwhile, in the related art, the data broadcasting system equipment provided by the data broadcasting solution company was used, and it was possible to implement the interlocking data broadcasting in connection with the existing cable TV home shopping broadcasting which is performed live.

That is, the contents constituting the caption data to be displayed on the screen currently being broadcast is set in the character generator, and the same contents are set through the real-time caption data update equipment of the data broadcasting system equipment. In addition, based on the caption contents set through the real-time caption data updating device, the content associated with the home shopping broadcast currently being broadcast is reconstructed and transmitted, thereby implementing linked data broadcasting.

However, when the contents constituting the caption data are manually set by an operator through a character generator and a real-time caption data updating device, the contents set in the character generator and the contents set in the real-time caption data update are considered. There is a great chance that this does not match or that errors and typos in the subtitle contents are caused.

In addition, before displaying the caption data generated by the character generator during home shopping broadcasting on the home shopping broadcasting screen, the caption data is displayed on a preview monitor and sent after being inspected by a switcher operator or PD.

However, since there is no means or a process for verifying the subtitle contents input through the real-time subtitle data updating apparatus through preview, there is a possibility of error and typos. In addition, after the final verification procedure is terminated by the switcher operator, PD, etc. to solve such a problem, the caption contents may be input through a real-time caption data updating device, and the linked data broadcasting contents may be configured and transmitted. . However, in this case, in providing the linked data broadcasting contents, it takes more time for the final inspection procedure to go through the switcher after being set in the character generator.

In addition, the current time of home shopping broadcasting is about 20 hours, the operator who manages the character generator, and also the operator who manages the data broadcasting system equipment should be composed of a large number of operators working in the situation that many of them work alternately 20 hours In addition to the costs, the cost of purchasing data broadcasting system equipment is also a considerable burden for home shopping companies.

Accordingly, the present invention was made in view of the above problems, and generates a subtitle displayed on a cable TV home shopping broadcast screen which is conducted live, by a character generator, and simultaneously transmits it to the DMC-data interlocking means in real time. Reconstruct the contents linked to the live home shopping broadcasting and reflect it in the data broadcasting application, and provide the data broadcasting application to the cable TV of the client through the digital set-top box, thereby implementing the linked data broadcasting linked with the existing home shopping broadcasting.
