Digital Broadcasting System Optimization Solution And Implementation

With the advancement of digital broadcasting,the new radio and television services are emerging,such as interactive HDTV,video on demand,mobile digital TV and so on.In the process of digital TV transformation,the broadcast control center computer room is an important part,and the broadcast system is the heart of the entire central computer room.With the development of digital technology,the all-digital hard disk broadcast system has gradually occupied the market with its advantages of high degree of automation and digitization,good stability and good expandability.In this paper,the TV broadcast system of the analog signal transition digital signal stage is upgraded and designed,and the scientific,security and extended functions involved in the system are discussed in depth.The domestic advanced TV stations basically adopt the digital broadcast control center system.This paper introduces the hardware equipment used in the INFO and SUNCAM broadcast system of the Guangzhou Radio and Television Digital Mobile Channel,as well as the broadcast control software and related technologies.After the digital transformation and channel expansion of the control center,the problems of the editing software generated during the process of simulating the transition digital INFO broadcast system used in the initial stage of the operation of the computer room are proposed for the INFO editing system that needs manual programming.The solution for optimization and design.In the comparative study of the expansion channel of the computer room,the newly added SUNCAM full digital broadcast control editing system proposes the requirements and upgrade value of the INFO system editing software upgrade.In view of the fact that the INFO system fails to automatically increase the broadcast server load according to the material used in the disk array screening and fails to automatically generate the system broadcast table according to the broadcast schedule,this paper proposes an automatic optimization design scheme and expands the system.Continuous availability reduces business costs and ensures broadcast security.This article redesigned and wrote the software for importing Scopy and generating system CrateXML based on C# program.In the actual operation process,the automatic screening and importing material program function of the INFO editing system and the function of automatically generating the broadcasting and broadcasting table according to the electronic program list are realized.After optimization,the entire editing time can be shortened from 4 hours to 40 minutes,and the production staff can be reduced from 8 to 2 people.Under the premise of ensuring the safety of broadcast,the low-cost transformation is completed,and the optimized old INFO is completed.The broadcast system has achieved the automatic scheduling function of the new SUNCAM digital hard disk broadcast system.
