Problems solved by technology

[0019] The level of each protocol layer of the FLO protocol stack is not strong. The FLO MAC layer is divided into three parts to process different types of data, which makes the implementation of the protocol stack complex. Moreover, FLO uses a very short time interval to transmit different program data, causing the terminal to need Frequent power on and off for data reception makes the terminal power consumption very serious

Embodiment Construction

[0078] The present invention provides a sending system in a video broadcasting system. The protocol stack framework of the sending system is shown in FIG. 1 .

[0079] In FIG. 1 , the protocol stack in the transmission system of the present invention includes: an application layer, that is, a high layer, a convergence layer, a radio resource control layer, a MAC layer, and a physical layer. The application layer here may also be called a high layer. Wherein, the aggregation layer, the radio resource control layer and the MAC layer may be collectively referred to as a data link layer.

[0080] The main function of the upper layer is to provide program stream data. The upper layer in the present invention may only support packet transmission, or only transparent transmission, or both packet transmission and transparent transmission.

[0081] The high layer in the present invention is composed of program stream data providing module, data service module, packet transmission modul...

Abstract

The invention discloses the sending system, the method, and the receiving system in video broadcast system. The sending system includes following layers and procedures: application layer provides stream data of program (SDP); wireless resources control layer provides the control information (IC) of SDP, and IC of common channel transmission for concourse layer and MAC layer as well as controls stream data transmission of program in the concourse layer and the MAC layer; based on received IC, the concourse layer partitions SDP; based on received IC, the MAC layer forms MAC frame from partitioned SDP and IC of common channel transmission; through physical layer, the MAC frame is transferred to the receiving system. Also including application layer, concourse layer, wireless resources control layer, MAC layer, and physical layer. The receiving system executes reversible operation of each layer in the sending system to implement receiving SDP. Features are: clear hierarchy, simple and clear procedure for transmitting SDP.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a sending system, method and receiving system in a video broadcasting system. Background technique [0002] All over the world, new digital TV systems are gradually replacing existing analog broadcast TV systems. Digital TV systems can improve spectrum utilization and provide higher quality and more types of broadcast TV services to meet users' needs for new TV, multimedia and communication business needs. [0003] The digital TV transmission system is an important part of the digital broadcast TV system. The digital TV transmission system must have the basic functions to support traditional TV broadcast services, and also need to be scalable to adapt to the new generation of digital TV and multimedia broadcast services, and even interactive information services. Function. [0004] Mobile TV refers to watching TV programs through mobile terminals. At present, mobi...
