The Newtec AZ850 Rate Adapter is a device designed to change or
stabilize the data rate of a transport stream. The AZ850 Rate Adapter provides
a fix and stable output data rate independently of the rate of the input transport
stream. The rate adaption is fully automatic for a maximum ease and convenience of
The AZ850 is the perfect solution when there is an accidental or a voluntary
difference between the output rate of an encoder/ multiplexer and the transmission rate of a modulator.
When the input data rate is lower than the output data rate, the AZ850 adds stuffing
packets to the transport stream to achieve the desired data rate.
When the input data rate is higher than the output data rate, the AZ850 identifies and
removes stuffing packets from the transport stream to reduce the transmission rate to desired value.
When the data rate of the input signal is unstable, the AZ850 will automatically add or
remove stuffing packets to restore a stable output rate.
The AZ850 performs a very precise restamping of the PCR time references in the transport
stream, guaranteeing the quality and stability of the timing recovery mechanism at the end of the transmission chain.
In its default configuration, The AZ850 has 2 ASI inputs which can be selected either manually
or automatically. One of the Electrical ASI interface can be optionally replaced by an optical interface.
Optionally, a high stability reference frequency can be added. The AZ850 is easy to operate and monitor.
All control and monitoring parameters are available locally on the front panel and remotely
through a web interface. It is also possible to control or monitor the AZ850 via RMCP or SNMP.
