Innovation Solution
A broadcast receiving apparatus is designed to receive and output content based on control information that includes copy protection, video resolution, and transmission characteristics, utilizing MMT (MPEG Media Transport) for efficient media transport and supporting advanced video coding methods like HEVC, enabling enhanced functionality and compatibility with broadband networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data broadcasting receiving function is utilized or extended, then various types of information can be received and displayed, but it is difficult to provide high-value added television receiver capable of satisfying demands for broadband network integration and high-resolution video content distribution
Solution Approach 1:
The television receiver is designed to perform multiple functions through a unified architecture that integrates both traditional data broadcasting reception and modern broadband network communication. The communication unit can operate in multiple modes (broadcast receiving, bidirectional communication, internet access) without requiring separate dedicated systems, thereby achieving high adaptability while controlling overall system complexity.
Solution Approach 2:
The receiver employs dynamic protocol selection and adaptive communication modes that can switch between different broadcasting standards and network protocols based on the received signal type and service requirements. This dynamic adaptability allows the system to handle diverse content distribution scenarios without needing separate hardwired configurations for each standard.
2Manufacturing precision
If conventional data broadcasting reception is used, then basic information distribution is achieved, but high-resolution and high-definition video content distribution with enhanced functionality cannot be provided
Solution Approach 1:
The system implements variable parameter control for video processing including resolution adjustment, bitrate adaptation, and format conversion. The control unit dynamically adjusts decoding parameters and output settings based on the received content characteristics and display device capabilities, enabling high-resolution video reproduction while maintaining compatibility with various distribution formats and network conditions.
3Adaptability or versatility
If television receiver functions are extended for various content distribution, then basic functionality is improved, but high-value added functions for advanced content distribution and cooperated applications cannot be realized
Solution Approach 1:
The control unit serves as an intelligent intermediary that manages communication between the receiving unit, decoding units, and output interfaces. It coordinates data flow, handles protocol conversion, and manages resource allocation across different functional modules, thereby enabling complex cooperated applications without requiring direct complex interconnections between all system components.

AI summary
A digital broadcast receiving apparatus capable of executing a function with a higher added value is provided. A broadcast receiving apparatus configured to receive contents includes: a receiving unit configured to receive the contents; an interface via which the contents received by the receiving unit is outputted; a control unit configured to control an output state of the contents from the interface. In this case, the control unit is configured to determine the output state of the contents from the interface in accordance with a combination of control information indicating a copy control state of the contents, control information for specifying necessity or not of protection when to output the contents, information indicating resolution of video of the contents, and information indicating transmission characteristics of video of the contents, which are received by the receiving unit together with the contents.
