MPEG-2 Configuration

Video GOP Time The hours, minutes and seconds for the GOP time, the creation time of the MPEG video stream. Can be set to one of three selections:

•Encoder Time (default)

•GMT Time

•Local Time

Note: Within the GOP header of the video stream is a Time Stamp, in hours, minutes and seconds. If the receiving application uses this time stamp, it is desirable to configure the encoder to insert a real time of day in either local or GMT time. If no application is using this data, the setting should be left at Encoder Time, which merely uses the time elapsed since the encoder hardware was last reset.

Meta Data	When Metadata is enabled a new field will appear on the screen
	allowing the operator to insert metadata strings into the video as User
	Data. The normal use of metadata is to allow accompanying
	synchronized URL references to displayed in rich media applications.
	The VBrick StreamPlayer has the capability of extracting the
	metadata references and presenting them to an appropriate
	application. Contact VBrick for details.
Meta Data String	Shown if Meta Data is enabled. Maximum 58 characters. Click Insert
	Now to insert the meta data string into the stream.

Configuration: Encoder > Audio

Models ending in other than -xxx0 may contain different types of audio hardware. The difference can be identified by physical differences in the audio connectors or by the revision number identified in Status: Encoder/Decoder Status – PLX EEProm Revision E. The model identified as PLX EEProm Revision 1 has black plastic collars around the L/R audio jacks. The model identified as PLX EEProm Revision 2 has metal screw-on collars. Where features differ between the models, the differences are noted. For example, certain VBSSM models do not support audio (see Table 1 VBSSM Models † for details).
