Digital television multiplexer remote control method based on Ethernet

Abstract

The invention discloses a digital television multiplexer remote control method based on Ethernet. The method comprises the steps that 1, each subtask module sends a task request to a data sending module; 2, a control client end identifies the type of a subtask and transmits an operating instruction sent by the subtask to a multiplexer client end through the data sending module via the Ethernet; 3, the multiplexer client end analyzes and processes the operating instruction and makes a response, if the operating instruction is a parameter setting instruction, parameters for multiplex processing are set, and if the operating instruction is a current parameter monitoring instruction, data is exchanged to the control client end; 4, the control client end receives the data and analyzes and monitors the data to end. Due to the adoption of a remote control multiplexer mode, the working state of one or a plurality of multiplexer(s) can be remotely controlled and monitored, EPG (Electronic Program Guide) information insertion can be remotely controlled, the bandwidth of an input channel is not occupied, and the processed information content is larger.

Description

technical field [0001] The invention relates to the field of digital TV signal multiplexing and transmission, in particular to an Ethernet-based remote control method for a digital TV multiplexer. Background technique [0002] The basic function of the digital TV signal multiplexer is to package and multiplex multiple TS (transport stream) streams conforming to the MPEG-2 standard according to certain rules, so as to transmit multiple digital programs in one analog bandwidth. [0003] In terms of remote control of multiplexers, domestic multiplexers at this stage can only insert Electronic Program Guide (EPG) information that can provide more value-added services into the transport stream through serial ports or external workstations. Both methods have problems of unstable performance or high cost. Therefore, the multiplexers produced by domestic manufacturers are rarely able to fully meet the market requirements. Foreign digital TV multiplexer products, whose technology i...

AI Technical Summary

Problems solved by technology

Foreign digital TV multiplexer products, whose technology is basically mature, can meet the current needs of digital TV program multiplexing, but the price is relatively expensive

At present, the domestic market mainly adopts foreign digital TV products. Even if domestic multiplexers are used in some places, the result is that the value-added services of the entire digital TV are missing, and it eventually leads to dissatisfaction and even resistance of ordinary citizens to digital TV.
