Basic operations DSK (downstream key) Characters or other images can be combined with the background image. There are 2 types of DSK; DSK1 and DSK2. Selecting the DSK type 1 Press the DSK1 DSK2 button to light its indicator, and display the DSK menu. 2 Use [F1] to display the DSK sub menu. 3 Use [F2] to select the Type item. DSK1: There are 4 options; Lum, Linear, Chroma, and Full. DSK2: There are 3 options; Lum, Linear, and Full. Lum (luminance key/ self key) Linear (linear key/ EXT key) This is for creating the key signals from the luminance component of the key fill signal. This is for creating the key signals from the luminance component of the key source signal. It is used when the key source signal and key fill signal are different. Since the luminance key is operated as a self key, the key fill signals are used as the key source signals. When the luminance key has been selected as the downstream key type, the key signals will remain unchanged even when the key source signals are switched. When using the linear key, use material with a black background and white characters or shape to be combined by the key as the key source signal. Material which is not black and white may not be combined clearly. Material with a white background and black characters, etc. can be reversed using the key invert function for use. 4 When the luminance key has been selected, the chroma components can be contained in the key signals generated in view of the fact that it is used as a self key. (This is not applied to the linear key.) Use [F3] to select the setting using the Lum Key item. Chroma On Chroma Off In addition to the luminance components, the chroma components are also factored in when generating the key signals. Use this setting if colors with low luminance components are used for the key signals (when, for instance, blue characters are to be removed). The key signals are generated only from the luminance components. 5 Use [F4] to select the fill type using the Fill item. Bus Matte The bus signal is used for the key fill signal. The internal fill matte is used for the key fill signal. Setting the fill matte color 1 On the DSK menu, use [F1] to display the Fill Matte sub menu. 2 Use [F2], [F3] and [F4] to adjust the Hue, Sat and Lum of the fill matte. ww To call the preset color Use [F5] to select the preset color using the Load item, and press the [F5]. ppWhen [F5] is pressed, what has been set so far is canceled and replaced with the preset color values. ppTo save the values that were set before calling the preset color, refer to "Memory". 56
