Abstract: A watching system by which a game video is distributed to display devices of a plurality of watching users has: a computer; the computer accepting viewer operations by the plurality of watching users; the computer evaluating a mutual relationship of input of the viewer operation by each of the plurality of watching users; and the computer controlling an operation effect corresponding to the viewer operation so as to change based on evaluation result of the mutual relationship.

Abstract: A background-sound switching method and apparatus is provided for switching of background-music data. A partitioning code represents an end position of a phrase of background sounds outputted through a speaker. A switching instruction device outputs a switching-instruction signal which causes switching from the background-sound data being outputted to a D/A converter to other background-sound data. Following output of the switching-instruction signal, a data-number controller stores in RAM a data number which defines a next background-sound data to be outputted to the D/A converter. A code detector detects the partitioning code of the background-sound data being outputted. At each time the partitioning code is detected, a switching controller determines whether or not the data number is stored in the RAM and, if the data number is stored in the RAM, the background-sound data being outputted is switched to the other background-sound data defined by the data number.

Abstract: A background-sound control apparatus, a background-sound control method, readable recording medium containing a background-sound control program, and a video game apparatus improve effectiveness of background-sound data provided over a predetermined number of channels. When background sounds are produced through a speaker, a sound-level controller controls output ratios for sound levels defined in background-sound data on a channel basis and uses a sound-level control function to perform crossfading sound-level control.

Abstract: A background-sound control apparatus, a background-sound control method, readable recording medium containing a background-sound control program, and a video game apparatus improve effectiveness of background-sound data within the predetermined number of channels. When background sounds are produced through a speaker, sound-level control means in sound control means controls output ratios for sound levels defined in background-sound data on a channel basis and uses a sound-level control function to perform crossfading sound-level control.

Abstract: A game machine having play-by-play announcement includes a monitor, a manipulator, a memory to store data for each of a plurality of vocal sound groups, each vocal sound group expressing a word in connection with the game; a controller operable to produce a new game scene on the monitor in accordance with a game program and an instructive signal generated by the manipulator, and designate data for a vocal sound group suitable to the produced new scene; and a sound generator to generate vocal sounds suitable for the new scene based on the designated data.
