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 drives the reform of the "Fundamentals of Digital Television Technology" course. Starting from the evolution characteristics of ultra-high definition technology, this study analyzes the reconstruction logic of the course knowledge system driven by the iteration of resolution, color gamut, frame rate, and coding standards, and establishes the coupling relationship between the industrial technology chain and teaching units. Accordingly, this study designs a project-based hierarchical architecture based on the acquisition and processing workflow of ultra-high definition signals, constructs modular task clusters centered on coding and transmission technologies, and sets acceptance criteria that integrate subjective and objective evaluation indicators. This study proposes an inquiry-based teaching process guided by the technical link, identifies technical difficulties and breakthrough paths in coding algorithms, transmission adaptation, and system integration, and constructs a formative evaluation mechanism based on project completion. This research provides a reform path for adapting the digital television technology course to the needs of the ultra-high definition video industry.
