Research on the Project-Based Teaching Reform of "Fundamentals of Digital Television Technology" for the Ultra-High Definition Video Industry

Abstract

The development of the ultra-high-definition video industry has changed the content of the "Fundamentals of Digital Television Technology" course. With the progress of ultra-high-definition technology, this paper studies the reconstruction logic of the course knowledge system based on iteration in resolution, colour gamut, frame rate and coding standards, and establishes a coupling relationship between the industrial technology chain and teaching units. Based on the above, this paper puts forward a project-based hierarchical structure for the acquisition and processing workflow of ultra-high-definition signals, organises modular task clusters according to coding and transmission technologies, and sets both subjective and objective acceptance criteria. Under the leadership of the technical link, inquiry-based teaching will be used to explore technical problems and find good solutions in coding algorithms, transmission adaptation, system integration, etc., and a formative assessment system based on project completion will be established. Given the high-definition video demand of the public, this paper will propose a reform plan to change the development direction of digital television technology.
