Display Recording via Network Media for Tuner-Limited Multi-Channel Capture

The patent applies the copying principle by creating a virtual copy of the broadcast signal through network media resources. Instead of using multiple physical tuner modules to tune multiple broadcast channels simultaneously, the system downloads broadcast program data from network media resources (such as internet protocol television streams) and stores it in the memory. This virtual copy allows the single tuner module to effectively record multiple programs without requiring multiple physical tuners, thus improving recording capability while maintaining device simplicity.

The patent applies the universality principle by enabling the single tuner module to serve multiple functions through network media resources. The system can record both traditional broadcast programs (using the tuner module) and network-based broadcast programs (using network media resources with URL addresses). This multi-functional approach allows the display apparatus to record a larger number of programs simultaneously - up to the capacity of the memory storage - without being limited by the number of physical tuner modules, thus improving both adaptability and recording efficiency.

The patent applies the intermediary principle by introducing network media resources as an intermediate layer between the broadcast program source and the recording process. Instead of directly relying on the tuner module to capture all broadcast signals, the system uses network media resources (containing URL addresses of broadcast programs) as an intermediary. The processor can download program data from these network resources and store it in memory, providing a flexible recording mechanism that improves efficiency while the network dependency is managed through alternative recording paths for traditional broadcast programs.
