System and method for providing survey using optical recording and reproducing apparatus {System and method for providing a survey 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 a system and method for providing a survey using an optical recording and reproducing apparatus for providing a survey through a network during Blu-ray Disc reproduction. .

In general, optical disks that operate as recording media capable of recording large amounts of data are widely used. 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, is a standard for dyes and substrates that allows mass production of movies, music, games, etc., at home, 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-ROM, 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 connected state can be checked and the related content can be viewed or downloaded while traveling to 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.

On the other hand, "KR 2003-0062424 (Samsung Electronics) 2003.9.6" is a service providing form interworking with the BD network and receives subtitle data based on multinational languages through the network, watching a desired subtitle by user's selection.
