Description

Unmanned automation system of digital set-top box {management system for digital set-top box}

The present invention relates to an unmanned automation system of a digital set-top box, in particular, a digital set-top box that is installed in a home or digital cinema system to provide a digital broadcast or various digital contents (eg, theatrical release movie) to a user is established by an administrator. It relates to an unmanned automation system for a digital set-top box that can be automatically operated on a schedule.

With the development of communication technology and the spread of computers, many people are accessing various information through the Internet. In addition, due to the development of digital technology, various digital contents are being provided. A representative example is digital broadcasting. In conventional analog broadcasting, a receiver receives a wireless broadcasting signal transmitted from a base station and provides the same to a user. However, such an analog broadcast has a disadvantage of being a one-way broadcast that can obtain only information provided by a broadcast station because the analog broadcast signal received from a base station is provided to a user.

But in the case of digital broadcasting, the story is different. Unlike conventional analog broadcasting, digital broadcasting enables two-way broadcasting. Two-way broadcasting is a broadcast in which a user simultaneously transmits video and audio, and provides such an interactive system mainly in a cable broadcasting. Therefore, the user can watch the broadcast as well as participate in the broadcast through the interactive broadcast.

Such two-way digital broadcasting is performed by a program converting device called a set top box, which is a device having a home communication terminal function necessary to use two-way broadcasting. It is connected to a network such as a two-way television or a video transmission service of a telephone company, and connected to a television monitor in a home. In addition, various standards, such as having a telephone interface or a connection interface with a PC, are also being examined so that data communication services such as telephone and personal computer (PC) communication can be simultaneously used.

Meanwhile, with the activation of digital contents, digital cinema systems are becoming popular in theaters instead of the conventional screening of films using films. Screening of films using conventional film is performed by a projector, which is a power source for operation, a reel for supplying the film, a light source for projection, an optical system for forming an image on the projection film, and a mechanism for driving the film. It is composed of a device for synchronous projection of sound, an electro-optical system for sound reproduction, a magnetic head for sound reproduction of a magnetic recording film, and a mechanism for fixing an image at a predetermined position of a projection film. It has the disadvantage of requiring a manpower.

On the other hand, digital cinema system uses a player that plays digital content files and A / V system to display the opening work as a digital content instead of a film, so that the movie can be screened with simple configuration and operation. Has

Increasing living standards and the development of the cultural industry have resulted in many A / V systems in homes as well as theaters. Home A / V systems are connected to set-top boxes or audio to output audio and video signals. Accordingly, the user can be provided with higher quality content.

As described above, the digital cinema system or the A / V system in the home has the advantage of easily playing digital content, but has a limited function to provide a variety of digital content, such as games, sports relay, video lectures, demonstration seminars, etc. There is a disadvantage that can not be.

That is, in order to provide such various digital contents, a multimedia apparatus providing the digital contents must be separately provided, and the digital cinema system or the A / V system in the home must be separately connected with the multimedia apparatus.

In addition, since the digital content source provided from each multimedia device has a different format for each device used, the digital content source of a different format may be used for use in an established digital cinema system or an A / V system in the home. The disadvantage is the conversion to audio and video signals used in A / V systems.

Accordingly, the applicant of the present invention particularly provides a method for providing viewers with various digital contents such as games, sports broadcasts, video lectures, demonstration seminars, and notification of other events, as well as a movie in a theater equipped with a digital cinema system. Studied. As a result of this, inventing a digital set-top box that can receive and provide digital broadcasting, as well as easily connect with various multimedia devices, and provide digital contents provided from multimedia devices to users through a pre-built A / V system. There was a bar. Furthermore, by converting digital content output from various multimedia devices into audio and video signals used in pre-built A / V systems, it is possible to easily connect a number of multimedia devices and to convert digital content of various formats to A / V systems. Invented a digital set-top box that can be provided through.

However, the applicant has operated a digital cinema system based on the above-described digital set-top box, and as a result, although various digital contents including the digital broadcasting were provided to the viewers, the screening schedule of the contents was comprehensively managed for this purpose. There was a difficulty in supervision.

For example, in the current theater industry, multiplex is the mainstream, so it is no exaggeration to say that all the theaters are complex theaters. Here, a multiplex generally includes a large number of theaters (normally 10 or more) and additional facilities in a building, including large parking lots, restaurants, cafes, shopping towns, and various exhibition halls. For example, Cineplex (Belgium), known as the world's largest, has 30 theaters and 9,500 seats. Therefore, it is even more difficult to integrate and manage such multiplexes, which are currently held in various parts of the country, to set screening schedules for a number of theaters scattered throughout the country, and to monitor whether the theaters are operating as planned.
