A bus control mode. By executing a transition, the A bus and B bus signals are
output to the programme 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 the 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.
The area or margin that is added to the edge of a wipe or key.
Its width and colour 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 colour
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 colour 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.
Only digital signals are handled by DVI-D.
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 programme bus are always output
as the programme images. By executing a transition, the programme bus and preset
bus signals are switched over.
A memory which can hold the video signals equivalent to one frame.
A function which matches the synchronization of non-synchronized video input
signals.
A function which continues the display of the same image, creating the impression
that the image has been "frozen".
This is the effect where the programme image is faded out to the black screen.
Interface signals which control auto transition from an external source.
The colour tone of the video signals.
The border or shadow added to the edges of keys.
The signal that uses key combination processing to fill in the areas left blank by the
key signals.
A parameter which is used to adjust the amplitude of the key signals.
A function which inverts the key signals.
This is the function that specifies the area for key combination using the box pattern,
etc. When only part of the area of the key signals is used, key combination is
executed with the unnecessary area masked.
The video signals for creating the key signals.
