An apparatus for processing packets in a multimedia terminal has a media
access controller to send and receive packets from a network. A digital
signal processor converts a series of incoming real-time transfer
protocol packets into an incoming digital signal and converts an outgoing
digital signal into a series of outgoing real-time transfer protocol
packets. A compression-decompression unit decompresses the incoming
digital signal and generates an output signal to an output device and
compresses an input signal from an input device and generates an outgoing
digital signal. A central processing unit sends and receives transmission
control protocol packets. The apparatus can store a packet in one of a
plurality of queues in a buffer and assign a priority to the packet based
on whether the packet is a real-time transfer protocol packet or a
transfer control protocol packet.
