list. Choices range from Best Effort (unmanaged network traffic, lower quality
streams) to Highest (CS5) (with managed network traffic and higher quality streams).
8. Enable or disable SAP (Session Announcement Protocol) by selecting or deselecting
the SAP Enabled: check box. When SAP is enabled, the SMP351 publicizes
the availability of a stream to decoder/players. SAP periodically multicasts session
description information on an industry standard multicast address and port, which
makes setting up a receiving decoder easier.
