Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current television receivers utilize existing data broadcasting receiving functions, then basic content reception is maintained, but high-value added functions and higher resolution video handling are insufficient

Engineering Contradiction:
ImprovefunctionalityVSAvoidvideo quality
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic output control that adapts to different content types and transmission characteristics. The control unit dynamically determines output states based on resolution information, transmission characteristics, and copy control information, enabling the system to optimize performance for each specific content scenario rather than using fixed capabilities

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters based on received control information. It adjusts output resolution, protection status, and transmission characteristics according to the specific content requirements, allowing the same hardware to deliver varying quality levels appropriate to each content type

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the apparatus outputs content with higher resolution and definition, then video quality is improved, but complexity of controlling output states increases

Engineering Contradiction:
Improvevideo qualityVSAvoidcontrol complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The control unit automatically determines the appropriate output state by processing received control information itself, without requiring external intervention or complex manual configuration. The system self-regulates its output based on the content's inherent properties such as resolution requirements and transmission characteristics

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from received control information to adjust its output behavior. By continuously monitoring copy control information, resolution data, and transmission characteristics, the control unit makes real-time adjustments to maintain optimal output quality while managing complexity through automated decision-making

Inventive Principle:
Principle #23Feedback

3Ease of operation

If the apparatus implements comprehensive control based on multiple control information types, then output management capability is improved, but processing requirements and system complexity increase

Engineering Contradiction:
Improveoutput managementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions by processing various types of control information (copy control, resolution, transmission characteristics) through a single integrated mechanism. This multi-functional approach simplifies the system architecture compared to having separate control circuits for each type of information

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.
