Performance

The performance of the VNS 104 depends on the bit rate of the PURE3 streams and the capability of the PC hardware it resides on.

If hardware limitations are encountered, the image may update more slowly. The VNS 104 monitors its performance and makes adjustments in real time to ensure the highest quality video. Decoding a source stream can be suspended when resource limits mean decoding is no longer possible.

Image Quality and Motion

When the hardware hosting the VNS 104 is unable to sustain performance at the bit rate of the connected stream, image quality is maintained at the expense of motion. Where a tradeoff must occur, the application throttles back to support a maximum 30 Hz refresh rate, independent of the encoded stream.

Host PC Resource Monitoring

The VNS 104 monitors the host PC resources at all times. It can suspend decoding of a single stream or all streams when resource limits in the host PC prevent normal decoding.

The application monitors resources and protects against problems that may cause the VNS 104 application or the operating system to fail.

NOTE: Resource limitations can occur if the bit rate of the streams is such that the packet density causes UDP frames to be dropped in the network (switch) or in the PC network card. Resource problems can also occur on a PC platform that does not meet the minimum requirements.
