A method and system for providing a multi-decoder based channel surfing service are disclosed. An aspect of the invention provides a method of providing a multi-decoder based channel surfing service for a digital broadcasting system that is connected by a network to a broadcast receiver. This method includes: extracting a video signal from each AV (audio/video) signal for a multiple number of broadcast channels; generating a first and a second channel-surfing video source using the multiple extracted video signals, where the first and second channel-surfing video sources include sub-videos for different broadcast channels; and transferring the first and second channel-surfing video sources and source configuration information regarding the first and second channel-surfing video sources to the broadcast receiver, with the broadcast receiver generating a channel-surfing screen by simultaneously decoding the first and second channel-surfing video sources by way of a first and a second decoder.

Disclosed is a multi picture searching service providing system. The multi picture searching service providing system includes a head end transmitting a multi moving picture including plural moving pictures, moving picture-related data for each of the moving pictures, and multi moving picture configuration information for each of the moving pictures, and a user terminal receiving the multi moving picture, the moving picture-related data, and the multi moving picture configuration information and provides a user with a moving picture searching view, which is created by editing the plural moving pictures and the moving picture-related data, according to predetermined searching view generation information and the multi moving picture configuration information
摘要:
A middle output electrodeless lighting system comprising: a resonator having a certain inner space and adapted to form a resonance mode by shielding a discharge of microwaves applied therein to the exterior and to allow a discharge of light generated to the exterior; an electrodeless bulb including a light emitting portion positioned in the inner space of the resonator to emit (generate) light upon plasmarizing light emitting materials filled therein by the microwaves applied to the resonator, and a supporting member to support the light emitting portion thus to allow the light emitting portion to be arranged up to a certain height in the inner space of the resonator; and an initial lighting unit disposed at one side of the inner space of the resonator to enhance concentration of microwaves toward the electrodeless bulb so as to stabilize an initial lighting of the electrodeless bulb.

An electrophotographic photoreceptor is provided containing a specific asymmetric naphthalenetetracarboxylic acid diimide derivative having a nitro group. An electrophotographic imaging apparatus, an electrophotographic cartridge, and an electrophotographic drum employing the electrophotographic photoreceptor are also provided. The naphthalenetetracarboxylic acid diimide derivative has high solubility in an organic solvent, compatibility with a binder resin, and electron transporting ability. The electrophotographic photoreceptor manufactured using the naphthalenetetracarboxylic acid diimide derivatives has an excellent electrostatic property.
