Abstract:
1. A method for utilizing a plurality of pre-encoded payload streams, the method comprising: receiving a plurality of digital payload streams associated with an audio stream clip file, wherein at least some of the digital payload streams are generated by encoding the audio stream clip file at different bit rates; selecting a first digital payload stream encoded at a first bit rate from the plurality of digital payload streams as the payload for a packet stream transmission being sent to a device under test (DUT); receiving, from the DUT, a bit rate change request that indicates a second digital payload stream encoded at a second bit rate from the plurality of digital payload streams is to be used as the payload for the packet stream transmission being sent to the DUT; and conducting a synchronization procedure that synchronizes a first packet of the second digital payload stream with a last packet of the first digital payload stream in order to transition the packet stream transmission from the first bit rate to the second bit rate, wherein the last packet is a packet being processed for the packet stream transmission at the time the bit rate change request is received.
