System and method for providing IP TV broadcasting service using optical recording and reproducing apparatus {System and method for providing IPTV contents using a bluray disk player}

The present invention relates to an optical recording and reproducing apparatus for reproducing a Blu-ray disc, and more particularly, to an IP television broadcasting service providing system and method using an optical recording and reproducing apparatus for providing an IP TV broadcasting service using the optical recording and reproducing apparatus. It is about.

IPTV stands for Internet Protocol Television, which is a service that provides contents such as video and broadcasting to a TV using high-speed Internet. It's a type of digital convergence in terms of the convergence of the Internet and television.

IPTV provides the broadcasting contents including the video, but there is no difference from general cable broadcasting or satellite broadcasting, but it has the feature of adding the bi-directionality. In other words, unlike general public broadcasting, cable broadcasting or satellite broadcasting, viewers can select and watch a program they want to watch at a convenient time.

In addition, the IPTV is different from the existing Internet TV is that it uses a television receiver instead of a PC monitor, and uses a remote control instead of a mouse. Therefore, in order to use IPTV, a television receiver, a set-top box, and an Internet line must be connected. In other words, you can connect a set-top box or a dedicated modem to your television and turn it on as if you were turning on the television. Therefore, even a person who is not familiar with a PC can easily enjoy various contents and additional services provided by the Internet, such as a search service and movie watching, using a remote control.

Currently, some countries, such as the United States, Hong Kong, Italy, and Japan, offer IPTV services. In Korea, IPTV pilot project co-promoting councils have been launched, and telecom operators are actively implementing IPTV services that make the most of their existing infrastructure. to be.

On the other hand, in the case of the broadcast service through the IPTV service, it is possible to provide more high-definition video by using a high-speed communication network, and users' demand for such a high-definition service is increasing. In addition, in the provision of video services using storage media, users' desire for higher quality and higher quality video services is increasing according to the speed of technology development.

In order to provide such a high quality and high quality video service, a technology capable of storing and reproducing a large amount of data is required. In general, an optical disc is widely used as a recording medium capable of recording a large amount of data. In particular, new high-density optical recording media, such as Blu-ray discs (hereinafter referred to as' BD's), which can record and store high-quality video data and high-quality audio data for a long time, have been developed.

BD based on next generation recording media technology is regarded as the next generation optical recording solution that can store more data than conventional DVD. Recently, many developers have been intensively researching international standard technical specifications related to BD with other digital devices.

The BD uses a 405 nm blue-violet laser, which is different in thickness from the conventional DVD with a dye layer for recording data. That is, the BD has a dye layer within 0.1 mm from the lower protective layer. This results in a more accurate focus of the laser that is shooting and receiving from the optical pickup, allowing more accurate reading and writing of the information. In addition, since the coating layer is thin in this way, the wavelength of light can be prevented from being disturbed, and the recording layer can be read accurately even in the vibration generated by the disk rotation.

The standard of BD can be divided into physical classification and logical classification. Physical classification is classification according to the physical type of the disk, and logical classification is classification according to the type of the disk. Physically dividing the BD into BD-ROM, BD-R, BD-RE. BD-ROM, which can only be read, defines the specifications of dyes and substrates so that content such as movies, music, and games can be produced in large quantities at a manufacturing plant, not at home. On the other hand, the recording standards BD-R and BD-RE have defined the definition of the special dyes that can be written once or written many times, or the information on the recording method and speed.

The logical classification of BD-ROMs is largely divided into BD-R / RE and BD-ROMs, and some of them are divided in detail. In particular, a mode for storing a movie in a BD-ROM is divided into a high definition movie mode (HDMV) and a BD-J (BD-Java).

The HDMV is a method for storing a high-definition movie title with a menu such as a DVD movie, and is a mode for easily and quickly storing contents. It sets the rules for movie codecs such as MPEG 2, MPEG 3, AVC, SMPTE VC-1, as well as audio codecs such as Dolby, DTS and DTS-HD, and independent menu composition and how high quality graphics should be placed. This mode can be applied to general high definition BD movie titles.

The BD-J is a unique mode of BD storage and includes an application programmed in Java. When the BD-ROM title of the BD-J mode is inserted into the Blu-ray playback device, the status of the network connection can be checked and related contents can be viewed or downloaded while traveling through the server while the Java program is running. For example, if you go to a movie and want to know more related information such as the actor or the background of the movie, you can select additional information from the menu to retrieve and execute various information on the Internet or network.

Meanwhile, as described above, in the case of IPTV, a TV must be connected to the Internet through a separate set-top box, and the set-top box must use an operating system such as Windows CE or Linux for data communication through the Internet. The use of such an operating system has the problem that the cost of the set-top box. In addition, when using the above-described Blu-ray Disc or DVD, etc., the inconvenience of having to install a set-top box and a disc player, respectively, in a display device such as a TV.

An object of the present invention is to provide an IPTV broadcasting service providing system and method using an optical recording and reproducing apparatus providing a function of IPTV by using a network access function provided by a Blu-ray disc reproducing apparatus.

The optical recording disc is a Blu-ray disc.

The system further comprises an authentication server for receiving authentication information from the optical recording and reproducing apparatus, and performing IPTV service use authentication for the optical recording and reproducing apparatus.

The authentication information is any one selected from a unique number of the optical recording and reproducing apparatus, IP information assigned to the optical recording and reproducing apparatus, unique information set by the user of the optical recording and reproducing apparatus, and information set by the user when subscribing to an IPTV service. It is characterized by the above.

The optical recording and reproducing apparatus performs a network communication function with an IPTV service server by a pre-stored Java application program.

The system may include a remote controller that performs short-range wireless communication with the optical recording and reproducing apparatus, and inputs mode setting information for setting a reproducing mode or an IPTV service mode of the optical recording disk to the optical recording and reproducing apparatus; It characterized in that it further comprises.

The optical recording and reproducing apparatus is characterized in that receiving at least one additional service information that can be serviced through a network when setting the additional service mode.

A method of the present invention for achieving the above object comprises the steps of selecting an IPTV mode in an optical recording and reproducing apparatus capable of driving and playing an optical recording disk; Receiving and displaying content list information available from an IPTV service server through a network; Selecting specific content from the provided content list and requesting transmission to the IPTV service server; And receiving the requested content information from the IPTV service server, converting the received content information into video and audio data, and reproducing the processed content information.
