Table 1. VBSSM Models †

Model	Configuration	Description
9170-4200-000x	VBSSM-MP2	Ruggedized single channel MPEG-2 encoder.
9171-4200-000x	VBSSM-MP4	Ruggedized single channel MPEG-4 encoder with
		audio. Same enclosure as VBSSM-MP2.
9172-4400-000x	VBSSM-MP2/4	MPEG-2 or MPEG-4. This device has a different
		enclosure with a single video input that supports
		two channels. It also supports RS-422 passthrough.
		VBSSM-MP2 does not.
9174-4200-000x	VBSSM-MP4	No audio.
9175-4200-000x	VBSSM-MP4	With audio.

Mixed Model Appliances

In addition to dual devices (for example two encoders, or an MPEG-2 encoder and MPEG-2 decoder), VBrick supports mixed model appliances (for example a WM encoder and an MPEG-4 encoder). VBrick appliance v4.1 software supports almost any combination of VBrick devices in Slots 1 and 2 so you can mix and match as necessary. For example, you can have a WM encoder in Slot1 and an MPEG-4 encoder in Slot2, or you can have an MPEG-2 encoder in Slot1 and MPEG-4 decoder in Slot2. The only exception is that you cannot have a WM encoder and an MPEG-4 decoder in the same appliance. In general, encoders are installed in Slot1; decoders are installed in Slot2. WM encoders, if present, are always installed in Slot1.

Note VBrick WM, MPEG-2, and MPEG-4 appliances all run the same codebase. The configurable options and user interface vary according to the type of appliance (e.g. MPEG-2, MPEG-4, etc.) on which the code is installed.

Archiver and Recorder Functionality

Archiver/Recorder functionality may be different in mixed model appliances depending on how the slots are populated. In other words, the behavior of the device in a given slot may change depending on what combination of appliances are installed. See Figure 1 below and note the following distinctions:

•An archiver only records from an associated encoder. For example, a WM Archiver is associated with a specific WM encoder.

•A recorder is not associated with any encoder. It independently records one stream at a time from an encoder, a decoder, or from the network.

•On MPEG-4 appliances, there is no archiving or recording.
