The Windows Media output window contains:
- IP Settings area: This area reflects the TCP/IP settings for the Windows Media Encoder that CaptionKeeper is connected to.
- Connection Settings button: The Connection Settings button displays a dialog which allows you to set up TCP/IP parameters for the Windows Media Encoder, as well as to set parameters for the text and window attributes of the SAMI caption stream that's created on a Windows Media Player.
- Listen checkbox: The Listen checkbox instructs the Real window to retrieve caption data from the currently selected input filter (typically the line-21 data-recovery decoder.)
- Webcast checkbox: The Webcast checkbox instructs the Real window to send caption data to the currently connected Real Server.
- Buffer Rollup checkbox and Lines picker: The Buffer Rollup controls allow CaptionKeeper to retain a specified number of roll-up caption lines before processing them for transmission or capture. This allows for rational display in window types that do not understand scrolling. Currently, text display in Windows Media Player does not support scrolling text.
- Capture Settings area: This area is used to enable, disable, and control the archiving of inbound captions. The output of the capture process is a **SAMI** file containing timecoded text. : The Offset function allows you to translate the system times into multimedia (zero-based) timecodes for on-demand use. The Open function allows you to open an existing timed-text file in SAMI format. Note that you can capture captions without sending them to a server. This capability can be used to convert captioned videotapes to on-demand captioned media clips.
