On the S4200, S4200-AS, and S4200-AS-2V devices, the composite signal of a video input
is sent to two separate encoders. You can customize each encoder to meet your system
needs, for instance in terms of frame rate and resolution. Here are typical scenarios
regarding encoder use:
The video resolutions supported by the S4200 device are:
The following performances can be achieved using single-stream encoding. For dual
encoding values, refer to the Nextiva Intelligent Edge Devices Single-Dual Stream
Performance document, available on the extranet (Community Links > Technical Briefs >
Nextiva Intelligent Edge Devices).
Each performance value includes:
A video resolution
A frame rate expressed in frames per second (fps) using the NTSC/PAL format
