Abstract:
1. A method to estimate media quality degradation resulting from wireless transmission to a device under test (DUT) to thereby characterize performance of the DUT, the method comprising: encoding a reference media signal into a stream of packets; imposing first simulated impairments to individual packets in the stream of packets to simulate degradation that could result from a first wireless transmission of the stream of packets over an interface with a peer media device; wherein the first simulated impairments simulate degradation resulting from wireless transmission over a first radio access network (RAN); transmitting the stream of packets over a radio frequency (RF) link; receiving the stream of packets at the DUT; capturing a degraded media signal derived from the stream of packets via the DUT; analyzing the degraded media signal to estimate the media quality degradation and characterizing the performance of the DUT by repeating the steps of encoding, imposing, transmitting, receiving, capturing and analyzing for a plurality of different simulated impairments.
