Selecting the key source Note When combined, a key source cannot be selected on the channel with the lowest number. It is fixed to [Ext Key]. 1 Open the DME >Input/Output >Video/Key menu (4162). 2 Select the key source in the group for the front input signal and in the group for the back input signal. Ext Key: Use the key signal sent from the switcher as the key source. Int Key: Use the full-size DME internal key signal as the key source. Lum Key: Use the input video luminance signal as the key source. 3 When [Ext Key] or [Lum Key] is selected, set the following parameters. No. Parameter Adjustment 1 Clip Reference level for key signal generation 2 Gain Key sensitivity Notes • [Ext Key] and [Lum Key] in the group share the [Clip] and [Gain] parameter settings. Similarly, [Ext Key] and [Lum Key] in the group share the [Clip] and [Gain] parameter settings. • When combined, the [Ext Key] parameter is disabled on the channel with the lowest number. Interpolation Settings This specifies the methods used for interpolation processing of input video signals and input key signals. For input video signals, you can select from the following four methods. • Detect changes in the luminance and chrominance signals separately, and switch automatically between fields and frames. You can select the degree of change detection. • Detect changes in the luminance signal separately, and switch automatically between fields and frames. You can select the degree of change detection. • Do interpolation in field units. • Do interpolation in frame units. For input key signals, you can select from the following three methods. • Detect changes in the luminance signal separately, and switch automatically between fields and frames. You can select the degree of change detection. • Do interpolation in field units. • Do interpolation in frame units. You can also select the number of pixels used in interpolation processing. You can also select the method used to show the picture reduced or expanded. Notes • The group and group settings are available only when the signal format is 1080i or 1080PsF. • When the signal format is 1080PsF, only [Field] or [Frame] in the group and group can be selected. When the DME is rebooted, the setting changes to [Frame]. • There is no restriction on the group and group settings due to the signal format. Selecting an interpolation method 1 Open the DME >Input/Output >Process menu (4163). 2 In the group, select the interpolation method for the video signal. Adaptive Y/C: Detect changes in the luminance and chrominance components of the video signal separately, and switch automatically between fields and frames. Adaptive Y: Detect changes in the luminance component of the video signal separately, and switch automatically between fields and frames. Field: Do interpolation in field units. This gives natural movement, suitable for movies. Frame: Do interpolation in frame units. This gives higher image precision, suitable for still pictures. 3 When [Adaptive Y/C] or [Adaptive Y] is selected in step 2, set the following parameter. No. Parameter Adjustment 1 Mode Degree of change detection 4 In the group, select the interpolation method for the key signal. Adaptive: Detect changes in the luminance component of the key signal separately, and switch automatically between fields and frames. 273
