Embodiment Construction

[0045] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention unclear.

[0046] Exemplary embodiments of the present invention improve video coding between, for example, Moving Picture Experts Group-4 / Advanced Video Coding (MPEG-4 / AVC), H.264, Scalable Video Coding (SVC), and Multiview Video Coding (MVC). The concept of network abstraction layer (NAL) used in the standard of video data of class, so that this improved concept can be applied to video data service and data service of other media (eg, audio, graphics, or text).

[0047] Such as figure 2 As shown in , the conventional NAL header 210 includes various kinds of information for indicating the importance of the video packet. Also, the NAL head...

Abstract

The present invention relates to a method and apparatus for transmitting a multimedia data packet. The method for transmitting a multimedia data packet comprises the following processes: 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.

Description

technical field [0001] The invention relates to a method and a device for sending multimedia data packets. More particularly, it relates to a method and apparatus for adaptively transmitting multimedia data packets according to a Quality of Service (QoS) scheme. Background technique [0002] For example, multimedia services refer to session services such as video telephony, data streaming services such as Video on Demand (VOD) services, multicast or broadcast services, and the like. Real-time multimedia services can be divided into conversational services, interactive services, and data streaming services according to service forms. Also, real-time multimedia services can be classified into unicast services, multicast services, and broadcast services according to the number of users participating in the services. [0003] In order to provide multimedia services, the schemes that provide QoS in the network can be divided into Best Effort (BE) schemes, per-class (per-class) ...
