Packets are acquired, the priority thereof identified and the packets sorted into high-priority packets and low-priority packets.

A packetizing unit (162) packetizes the stream and transmits the packetized stream to the host terminal.

A packet converter converts the packets identified by the specified PID to an IP packet having the IP address.

The vocoder is operable to convert speech signals into packets and convert packets into speech signals.

In one embodiment of the invention, media data is grouped in structured packets referred to as Packetized Elementary Stream (PES) packets.

The voice packets from the push-to-talk device are converted to text packets.

The method also includes classifying (304) the incoming packets as offending packets and non- offending packets in non-real time.

The method includes filtering (302) incoming packets in real time by using a recent offender list (212).

The MPEG-4 streams can be encapsulated into MPEG-2PES (Packetized Elementary Streams) packets or directly into MPEG-2 transport packets.

The method may separate the received seismic data into refraction packets and reflection packets.

The voucher carriers are typically grouped in uniquely identifiable packets containing multiples thereof and the packets may be grouped with other packets into uniquely identifiable batches thereof.

The image layers are packetized to produce packet streams.

The UDP packets are translated back to TCP packets and routed to the receiver.

In the packet scheduling method, the sequences of the pictures are divided into motion part packets and texture part packets, and priorities are assigned to the packets according to temporal scaling.

The encoded video stream is then packaged such that the GOPs are stored in data packets of the packaged encoded stream.
