Cea708CaptionEmitCommand

CEA708 Caption Emit Commands constants. MLCea708CaptionEmitCommand from ml_media_cea708_caption.h .

Enumerator	Value	Description
Buffer	1	Buffer command.
Control	2	Control command.
CWX	3	SetCurrentWindow tells the caption decoder which window the following commands describe:

• SetWindowAttributes
• SetPenAttributes
• SetPenColor
• SetPenLocation. If the window specified has not already been created with a DefineWindow command then, SetCurrentWindow and the window property commands can be safely ignored. | | CLW | 4| ClearWindows clears all the windows specified in the 8 bit window bitmap. | | DSW | 5| DisplayWindows displays all the windows specified in the 8 bit window bitmap. | | HDW | 6| HideWindows hides all the windows specified in the 8 bit window bitmap. | | TGW | 7| ToggleWindows hides all displayed windows, and displays all hidden windows specified in the 8 bit window bitmap. | | DLW | 8| DeleteWindows deletes all the windows specified in the 8 bit window bitmap. If the current window, as specified by the last SetCurrentWindow command, is deleted then the current window becomes undefined and the window attribute commands should have no effect until after the next SetCurrentWindow or DefineWindow command. | | DLY | 9| Delay suspends all processing of the current service, except for DelayCancel and Reset scanning. | | DLC | 10| DelayCancel terminates any active delay and resumes normal command processing. DelayCancel should be scanned for during a Delay. | | RST | 11| Reset deletes all windows, cancels any active delay, and clears the buffer before the Reset command. Reset should be scanned for during a Delay. | | SPA | 12| The SetPenAttributes command specifies how certain attributes of subsequent characters are to be rendered in the current window, until the next SetPenAttributes command. | | SPC | 13| SetPenColor sets the foreground, background, and edge color for the subsequent characters. | | SPL | 14| SetPenLocation sets the location of for the next bit of appended text in the current window. It has two parameters, row and column. | | SWA | 15| SetWindowAttributes Sets the window attributes of the current window. | | DFX | 16| DefineWindow0-7 creates one of the eight windows used by a caption decoder. |
