Abstract: The present invention is directed to provide an AV processing device and the like that allow mixing three or more AV signals through easy operation. According to the invention, an AV processing device 30 includes an input unit 310 inputting three or more AV signals that are audio signals or video signals, a coordinate point assigning unit 322 assigning a given coordinate point in a predetermined two-dimensional region in which a coordinate axis for each input AV signal indicating its mixing rate from minimum to maximum is virtually assigned, a mixing rate calculator 331 calculating the mixing rate of each AV signal based on the coordinate axis for the AV signal and the assigned coordinate point, a mixed AV signal generator 332 generating mixed AV signals based on the calculated mixing rate of each AV signal, and an output unit 350 outputting the generated mixed AV signals.

Abstract: Provided herein is an AV processing apparatus which displays a plurality of video signal designating areas which are used to designate an output of each video signal on a touch panel in accordance to a plurality of input video signals, performs a mixing process based on a touch position on the touch panel, and performs a switching process of video signals based on a movement of the touch position.

Abstract: An AV complex editing apparatus includes an effect category selecting unit (E1) which selects any effect category among a plurality of effect categories, and an effect mode selecting unit (E4) which selects a signal to be an object of effect processing. The specification of an effect operation screen 210 is changed in accordance with a selected result by the effect category selecting unit (E1), while the specification of the effect operation screen 210 is not changed in accordance with a selected result by the effect mode selecting unit (E4).

Abstract: A signal processor comprises: a first buffer memory for outputting an image signal after storage; a second buffer memory for outputting an audio signal after storage; and a playback control section. The play back control section variably adjusts the playback progress speed of at least one of the image signal and the audio signal by individually controlling the output timings of the image signal and the audio signal from the first and second buffer memories in response to a given command.

Abstract: A rotational operation mechanism for a DJ apparatus enables smooth rotation to be achieved using a simple configuration. A rotational operation mechanism has a base, a display window member fixed onto the base, a ring member positioned on the display window member and holding a plurality of rotatable balls, and a rotation operation portion positioned on the ring member and operated by an operator. Mutually facing surfaces of the display window member and the rotation operation portion are provided with grooves that have substantially the same diameter as the ring member. The ring member is sandwiched between the display window member and the rotation operation portion such that the plurality of balls are received in the groove of the display window member and the groove of the rotation operation portion, and the ring member is rotatable in a peripheral direction.

Abstract: A multimagazine disc player includes an array of magazines removably stored therein each for holding a plurality of discs, and a playback device movable and positionable in alignment with one of the magazines at a time for playing back a selected one of the discs contained in the magazine. The discs stored in the magazines can selectively be played back automatically, and can also easily be replaced with other discs not stored in the disc player. The magazines are arrayed horizontally to make the disc player highly stable. The discs are stored in vertically erected positions so that the magazines can be removed and loaded with ease.

The discs stored in the magazines can selectively be played back automatically, and can also easily be replaced with other discs not stored in the disc player. The multimagazine disc player also has a magazine presence/absence detecting means for detecting whether each magazine is loaded or not, so that a wasteful time which would otherwise be consumed by moving the playback means to a position where no magazine is loaded can be eliminated.
