Abstract:
1. A method of an I/O device for encoding of audio data for communication, the device including a queue controller of a single input queue, the method comprising: receiving at least one input stream that is an audio packet stream; and receiving control signals to transform the single input queue by processing at least one of: a first control signal to switch between a first input stream having a first encoder parameter and a second input stream having a second encoder parameter; and a second control signal to switch between a first encoder parameter and a second encoder parameter within the input stream; determining, based on the first encoder parameter and the second encoder parameter, whether the single input queue anticipates heterogeneous audio packet types; transforming the single input queue from having heterogeneous packet types to a queue having homogeneous packet types in a case where heterogeneous audio packet types are anticipated; and transmitting an output audio packet stream having homogeneous packet types; and processing a hard handoff, as indicated by the first control signal, when the first encoder parameter and the second encoder parameter are the same or are different, the processing comprising: flushing the single input queue having packets from the first input stream; generating packets to replace lost packets; and populating the single input queue with packets from the second input stream.
