The present invention relates to a method of driving plasma display panel. A method of driving a plasma display device driven by dividing a plurality of scan electrode lines into the m (m is a integer more than 2) number of groups, according to the present invention includes: applying p (p is a natural number more than 1) number of first reset pulse having a first voltage to the scan electrode lines included in more than one group among m number of groups during a specific frame; and simultaneously applying q (q is a natural number more than 1) number of second reset pulse having a second voltage different from the first voltage to the second electrode line included in the rest groups except for more than one group during the specific frame.

Content encryption information on content data recorded on a recording medium. A plurality of encryption keys used for encrypting a plurality of data clips containing content data is stored in a key file and index information for associating each of the plurality of encryption keys with a data segment encrypted with the encryption key is placed in the key file or in another management information file (e.g., clip information file). As a consequence, it is allowed to decrypt encrypted content data with different encryption keys by applying each of the plurality of encryption keys to each associated data segment.

A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. A method for reproducing data from a recording medium using a local storage includes the steps of: a) downloading data associated with the recording medium, and storing the downloaded data in the local storage; b) generating a virtual package using a binding unit with missing data associated with the recording medium, such that the virtual package includes a PlayList capable of being played before all the data is completely; and c) playing the PlayList while the missing data is downloaded. Therefore, the method can effectively reproduce additional data, which is downloaded in the local storage in association with the recording medium, resulting in the creation of more convenient functions for a user.

A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. A method for reproducing data from a recording medium using a local storage includes the steps of: a) downloading an additional data file and a binding unit manifest file, and storing the additional data file and the binding unit manifest file in the local storage; b) determining a binding unit from among the downloaded additional data file according to the binding unit manifest file; c) performing a binding operation for binding the binding unit with an original data file contained in the recording medium according to the binding unit manifest file, and forming a virtual package; and d) reproducing additional data and original data using the formed virtual package.
摘要:
The present invention relates to a method for securing content on a recording medium. Input content data are encrypted and recorded on a recording medium. A resultant value obtained by applying a hash function to the content data recorded after encryption is recorded on the recording medium for validation of the content. According to the present invention, once hashing operation for validation of content is carried out after encryption of content data is done, an apparatus for reproducing a recording medium storing content can easily check the validity of stored content by carrying out hashing operation only.

A recording medium, a method for searching for content data from the recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. The recording medium includes a stream area for storing content data, and a reproduction management area for storing a search file capable of searching for the content data. The search file divides the content data into a plurality of scenes. If the content data supports a multi-angle, the search file classifies the scenes according to angles, and includes attribute for specifying the angles. Therefore, the recording medium can easily search for a variety of content data recorded in the recording medium, can provide the searched result, and can effectively reproduce/manage data of the recording medium, resulting in the creation of more convenient functions for a user.

The present invention relates to a controller effectively controlling the power for a washing machine and a drier, and a method of doing the same. More particularly, it relates to a controller for a washing machine or a dryer, and a method for supplying the power so that a washing machine and a drier as a one body may perform an optimal efficiency in a range of a current limit, when supplied the power by the same power source. A controller for a washing machine comprising a micom; and communication means for communicating with a controller of a dryer. A controller for a dryer comprising a micom; and communication means for communicating with the controller of the washing machine.
摘要:
A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. If downloaded data is stored in the local storage and enters an updatable state, it is updated to a local storage file structure. A binding unit is formed in the updated local storage file structure, and the formed binding unit is combined with a recording medium file structure, such that a virtual package is formed. Therefore, recording medium data and/or downloaded local storage data are reproduced according to the formed virtual package.
摘要:
A recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. The recording medium includes a first area for recording a stream including a plurality of Groups Of Pictures (GOPs); and a second area for recording GOP type information (GOP_type) classified according to GOP lengths. Therefore, a data stream recorded in the recording medium can be effectively reproduced, resulting in greater convenience of use.
摘要:
A method and apparatus for reproducing data from a recording medium using a local storage is disclosed. The method for reproducing data of a recording medium using a local storage includes (a) reading a binding unit associated with a specific recording medium from the local storage; (b) forming a virtual file structure using a binding operation for combining the binding unit with a file structure recorded in the recording medium; and (c) reproducing data contained in the recording medium and/or data contained in the local storage using the formed virtual file structure.
