Abstract
Official abstract text for this publication.
A method and an apparatus for transmitting a multimedia data packet are provided. The method includes generating Media Abstraction Layer (MAL) information for abstracting information on the multimedia data to be transmitted, generating a multimedia data packet including said MAL information, and transmitting the generated multimedia data packet to a network entity.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of transmitting a multimedia data packet, the method comprising: identifying, by a processor of a transmitter, media abstraction layer (MAL) information relating to multimedia data to be transmitted; generating, by the processor, a multimedia data packet including the MAL information; and transmitting, by the processor, the multimedia data packet, wherein the MAL information comprises media classifier information indicating a priority for a transmission of the multimedia data packet, and wherein the MAL information is identified in an application layer. 2. The method of claim 1 , wherein the media classifier information is included in any one of a type of service (TOS) field of an internet protocol version 4 (IPv4) packet header or a traffic class (TC) field of an internet protocol version 6 (IPv6) packet header. 3. The method of claim 1 , wherein the MAL information comprises label information, and wherein the label information includes an identifier for differentiating a stream of the media data. 4. The method of claim 3 , wherein the label information is included in any one of an extended field of an internet protocol version 4 (IPv4) packet header or an extended field of an internet protocol version 6 (IPv6) packet header. 5. The method of claim 3 , wherein the label information is generated by substituting a part that repeats in a user datagram protocol (UDP) header and a real-time transport protocol (RTP) header of the multimedia data packet into a flow label.
