A bus control mode. By executing a transition, the A bus and B bus signals
are output to the program images alternately.
The auxiliary data other than the video signals which is transmitted inside
the data stream of the video serial interface. The data superimposed on the
vertical blanking period is referred to as the V ancillary data (VANC).
The ratio between the horizontal and vertical dimensions of an image or
screen.
It is 16:9 for the HD format and 4:3 for the SD format.
A spare bus which can be switched by signals other than the main line
output signals.
A function to automatically adjust the input image signal phase to the
horizontal synchronization reference signal phase.
The black burst signal. A full-screen black level composite signal which is
used as the reference signal for gen-lock.
The area or margin that is added to the edge of a wipe or key.
Its width and color can be adjusted. The defocusing of the area around a
border is referred to as the soft effect.
This refers to the function for creating the key signals based on the color
information of the video signals and combining the keys.
The threshold level of the luminance when key signals are created from a
key source.
The signals which are output from the internal color generator and used as
the background image.
This refers to the effect where the display is instantly switched to the next
image.
A parameter which is used to adjust the density of the key signals.
This treats images as actual size (1) images. With PinP, it allows SD
images to be combined with HD images with no accompanying deterioration
in the images themselves.
This is the function that converts material in the HD format into the SD
format.
This refers to the key combination process which is performed at the end of
the mix effect. The key is always combined with the foremost image.
This refers to the transition patterns accompanying size reductions or slide
effects.
A digital video interface standard.
DVI-I can handle both digital signals and analog signals.
This refers to the audio data packets which are transferred inside the data
stream of the video serial interface.
A bus control mode. The signals selected by the program bus are always
output as the program images. By executing a transition, the program bus
and preset bus signals are switched over.
This function uses DVE effects to move, expand or reduce key signals.
