Abstract:
A game system having a high efficiency of compression transmission of image hard to compress conventionally. A game data delivery device (100) transmits delivery data including image identification data (122) for judging whether or not the image is a special image. A receiving game machine reads special image data (242) stored in a storage unit (240) if the delivery data represents a request for display of a special image, and displays the special image with which a real-time game image is replaced on an image display unit (220) .
Abstract:
An apparatus for image regeneration produces substantially the same digital data as the original, without using oversampling or special hardware, from analog data converted from the original digital data. An analog signal converted from a digital signal in an image generator (200) and a synchronizing signal from the image generator (200) are input to an image-regenerating device (100). Based on frequency data (82) and phase data (84) selected by a selector (80) and an input horizontal synchronizing signal (12) , a clock generator (30) generates sampling clock pulses whose phase is appropriately adjusted with the same frequency as the dot clock pulses for the generation of the digital data. Based on the generated sampling clock, an analog-to-digital converter (40) regenerates digital data from the input analog signal.
Abstract:
A game system in which clock signals of devices can be synchronized with each other. A game machine, a game data delivery device, an image data delivery system, and computer-usable information are also disclosed. A game data delivery device (100) generates a reference clock serving as a reference for synchronization by means of an internal clock generating section (180), a clock selecting section (160), and a clock generating section (120), superimposes the reference clock on game data by means of a clock/data superimposing section (170), and thereby delivers the resultant as delivery data to a game machine (200). The game machine (200) extracts the reference clock by means of a clock/data separating section (272) and generates operating clocks on the basis of the reference clock by means of a clock generating section (220) for game executing means such as a game data reproducing section (290).
