Abstract
Provided is a packet processing apparatus and method for audio/video (AV) data transmission, in which a simple protocol optimized for AV data transmission is used. Information distinguishing a data packet from a control packet may be included in a data link layer packet header, so that a data packet and a control packet may be distinguished from each other and thereby may be processed according to different procedures.
Claims34
A packet producing method comprising:
- determining whether information to be transmitted comprises data or control information;
- generating a data link layer packet header comprising information used to distinguish a data packet from a control packet, according to the determining;
- and
- encapsulating the information to be transmitted by using the data link layer packet header.
A packet processing method comprising:
- determining whether an upper layer packet included in a payload of a data link layer packet is a data packet or a control packet, by analyzing a header of the data link layer packet;
- and
- processing the upper layer packet according to separate procedures according to the determining.
A packet producing apparatus comprising:
- a determination unit which determines whether information to be transmitted is data or control information;
- a header generation unit which generates a data link layer packet header comprising information used to distinguish a data packet from a control packet according to the determination;
- and
- an encapsulation unit which encapsulates the information to be transmitted by using the data link layer packet header.
A packet processing apparatus comprising:
- a determination unit which determines whether an upper layer packet included in a payload of a data link layer packet is a data packet or a control packet, by analyzing a header of the data link layer packet;
- and
- a processing unit which processes the upper layer packet according to separate procedures, according to the determination.
A packet transmission system comprising:
- a transmitter which transmits a data link layer packet that comprises information distinguishing a data packet from a control packet in a header of the data link layer packet;
- and
- a receiver which receives the data link layer packet and determines whether an upper layer packet included in a payload of the data link layer packet is a data packet or a control packet by analyzing the header of the data link layer packet, and processes the upper layer packet according to different procedures according to the determination.
A data link layer packet comprising:
- a data link layer packet header comprising information used to distinguish a data packet from a control packet;
- and
- a data link layer packet payload.
A tangible computer readable recording medium having recorded thereon a computer program for executing the method of:
- determining whether information to be transmitted comprises data or control information;
- generating a data link layer packet header comprising information used to distinguish a data packet from a control packet, according to the determining;
- and
- encapsulating the information to be transmitted by using the data link layer packet header.
A packet based transmitting and receiving system, the system comprising:
- a packet transmitting unit comprising:
- a determination unit which determines if information to be transmitted is data information or control information,
- a header generation unit which generates a link layer packet header comprising information which distinguishes data information from control information, according to the determination,
- an encapsulation unit which encapsulates the information to be transmitted by using the link layer packet header and thereby produces a data link layer packet, and
- a transmitting unit which transmits the data link layer packet;
- and
- a packet receiving unit comprising:
- a receiving unit which receives the data link layer packet transmitted by the transmitting unit,
- a packet type determination unit which analyses the information which distinguishes data information from control information,
- a processing unit which processes the link layer packet according to a first procedure or a second procedure, according to analysis.
A tangible computer readable recording medium having recorded thereon a computer program for executing the method of:
- determining whether an upper layer packet included in a payload of a data link layer packet is a data packet or a control packet, by analyzing a header of the data link layer packet;
- and
- processing the upper layer packet according to separate procedures according to the determining.
