This invention provides a method for displaying encoded images, method and apparatus for playing the encoded images. The apparatus comprises a display device and a decoding unit. The decoding unit acquires a Bit-Per-Pixel (BPP) value from an encoded image, acquires a first bit stream from a first encoded image, acquires multiple first pixel data indices by segmenting the first bit stream every lengths of the BPP value, acquires a first pixel color value of each pixel data index by retrieving a palette comprising multiple unique pixel color values respectively labeled by multiple first pixel data indices, and outputs the acquired first pixel color values so as to play the first encoded image. The method and apparatus for playing the encoded images provided this invention play the encoded images through acquiring the pixel color values of the pixel data indices and outputting the acquired pixel color values to the player, so that coding and decoding can be effectively executed and the image playing time can be reduced.

The embodiment of the invention provides a video playing method and device. The method comprises the following steps: acquiring a plurality of pieces of playing speed description information respectively related to a plurality of time intervals of a video; and playing video fragments corresponding to the time intervals according to the acquired playing speed description information related to eachtime interval. According to the embodiment of the invention, a user can play the video fragments corresponding to the related time intervals according to the acquired playing speed description information without doing extra operation. An actual playing time length of each video can be shortened without affecting the video watching experience of the user by reasonably setting the playing speed description information of the different time intervals, so that more videos can be played within the same time period, the video playing efficiency of a video service party is greatly improved, and thevideo watching efficiency of the user is greatly improved.

A display control method and a display control apparatus connected to a display apparatus acquires, from a recording apparatus which records drawn contents in a drawing area upon receiving operation information representing an operation in the drawing area, pieces of the operation information and the drawn contents, and determines, of the acquired pieces of the operation information, operation information which is not to be used for playback of drawn contents and decides a playback timing of drawn contents based on the order or the timing in which the operation information is received. Operation information other than the operation information determined not to be used for playback is extracted, and the drawn contents on the display apparatus are played back at the decided playback timing using the extracted operation information.

A broadband optical spectrum generating apparatus 20 includes a ultrashort pulsed fiber laser 22 that generates pulsed light having a pulse width in the unit of picosecond to femtosecond, and broadband optical spectrum-generating optical fibers 24 that are connected with the ultrashort pulse fiber laser 22 via a lens 26 and have characteristics of normal dispersion, that is, a nonlinear coefficient of not less than 10 [W−1km−1] and a magnitude of wavelength dispersion of not greater than a value 0 [ps / km / nm] with regard to a wavelength of the pulsed light. The resulting output is super continuum that is widely broadened to a wavelength band of 1400 nm to 1750 nm and is chirped to a linear characteristic.

Playback which allows the user to easily grasp playback contents is implemented by a simple method while shortening the playback time in a display control apparatus capable of sequentially playing back drawn contents. This invention relates to a display control apparatus connected to a display. The display control apparatus includes a first acquisition unit which acquires an operation information table and drawing object information table from a recording device connected to the display, a second acquisition unit which acquires, from a playback method setting table, a playback method for playing back drawn contents on the display by using the operation information table and drawing object information table acquired by the first acquisition unit, and a playback unit which plays back the drawn contents on the display by using the operation information table and drawing object information table based on he acquired playback method.

A game machine includes: game medium release means that releases a plurality of game media to a determination area included in a game space based on an operation input from operation section; detection means that detects the occurrence or non-occurrence of a predetermined event at a plurality of determination points provided in the determination area, the predetermined event occurring due to a released game medium among the plurality of game media; and determination means that performs a win determination process based on the occurrence or non-occurrence of the predetermined event at the plurality of determination points provided in the determination area, the determination means determining that the player has won the game when a plurality of determination points among the plurality of determination points at which the predetermined event has occurred satisfy a winning condition.

The present invention relates to data application technologies in the field of video surveillance, and discloses an intelligent playback method for video records based on a motion information and an apparatus thereof. The method comprises the following steps: searching for all motion detection additional information conforming to a time period of a playback request in a hard disc, and storing the motion detection additional information as a motion information in a motion information linked list in terms of a time sequence; obtaining a current playback mode and a current playback time, and looking up a nearest motion information under the current playback mode and the current playback time from the motion information linked list; matching the found nearest motion information with the current playback time; controlling a playback speed according to a matching result, so as to implement an automatic control of an intelligent playback speed. A real-time, automatic, continuous control of a playback speed can be implemented by repeating performing the above steps, so that automatically adjusting to a normal playback speed when there is motion data and automatically adjusting to a rapid playback when there is no motion data are implemented, and a playback time of video records can be reduced.

A playback system includes headphones worn on a user's body and converting an electrical signal into sound and a playback apparatus supplying the electrical signal to the headphones. The headphones include first and second electrodes provided in first and second converters, respectively, so as to be in contact with the user's body. The first converter converts the electrical signal in a right channel into sound. The second converter converts the electrical signal in a left channel into sound. The playback apparatus includes measuring means for measuring a resistance or a capacitance between the first and second electrodes, determination means for determining whether or not the headphones are being worn on the user's body in accordance with the resistance or the capacitance measured by the measuring means, and control means for controlling a state of the playback apparatus in accordance with the determination result of the determination means.
