Broadcast protocol transmission method based on network digital broadcast system

Abstract

The invention relates to a broadcast protocol transmission method based on a network digital broadcast system. The broadcast protocol transmission method comprises the steps of S1 defining the standard for transmitting a data packet according to the communication transmission requirements of the network digital broadcast system and broadcast hardware; S2 determining basic information according to a configuration information synchronization data packet command issued by the network digital broadcast system, wherein the basic information corresponds to a broadcast hardware device which needs to execute the command and the basic information comprises a broadcast area, an information source and / or an information channel; S3 executing a playing data packet command issued by the network digital broadcast system by the broadcast hardware; S4 obtaining the broadcast state, the information channel occupation state and the equipment state according to a state obtaining data packet command issued by the network digital broadcast system; S5 conducting direct operation by the hardware side according to a controlling data packet command issued by the network digital broadcast system.

Description

technical field [0001] The invention relates to the technical field of system design, in particular to a broadcast protocol transmission method based on a network digital broadcast system. Background technique [0002] Since the 1990s, my country's railway informatization has developed rapidly, and the railway passenger lines and passenger flow density have shown a linear growth trend. The operation of railway transportation is facing unprecedented challenges. At present, artificial broadcasting is gradually being replaced by an intelligent network digital broadcasting system. Clarifying broadcast command transmission protocol standards is an important means of establishing a standard network digital broadcasting system, and an important way to improve the quality of railway passenger transport services and achieve sound and rapid development of railways.
