Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tuner apparatuses are designed for specific digital broadcast transmission standards, limiting their use in areas with different standards, leading to incompatible jacks and inability to receive broadcasts across varying transmission standards.
Innovation Solution
A global integrated tuner apparatus with multiple connectors for different digital broadcast standards and a switch device to selectively connect them, controlled by a controller that identifies the area and ensures proper connection based on the standard, allowing seamless reception across different standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tuner apparatus is designed for a specific digital broadcast transmission standard, then the tuner can operate reliably in that standard's area, but the tuner cannot be used in areas with different transmission standards
Solution Approach 1:
The tuner apparatus is designed to support multiple digital broadcast transmission standards (ATSC, DVB, ISDB) through integrating multiple connectors and tuners into a single device. The switch device enables the apparatus to adapt between different standards by connecting to the appropriate connector based on the detected broadcast standard, allowing one device to function universally across different regional standards while maintaining reliable operation for each standard.
2Reliability
If separate tuner apparatuses are developed for different digital broadcast transmission standards, then each standard can be optimized, but the number of development models and samples increases
Solution Approach 1:
The patent merges multiple tuner apparatuses designed for different broadcast standards into a single integrated tuner apparatus. Multiple connectors (ATSC, DVB, ISDB) and corresponding tuners are combined in one device, sharing common components such as the switch device, controller, and display device. This consolidation reduces the number of development models and samples while maintaining the standard-specific optimization benefits through separate tuner modules for each broadcast standard.
3Adaptability or versatility
If multiple connectors for different broadcast standards are integrated into a single tuner apparatus, then the apparatus becomes versatile, but the device complexity increases
Solution Approach 1:
The switch device serves as an intermediary component that manages the complexity of multiple connectors and tuners. It automatically selects and connects the appropriate connector based on the detected broadcast standard, acting as a mediator between the user interface and the various standard-specific tuners. This intermediary mechanism enables versatility across multiple standards while simplifying the user experience and controlling internal complexity through automated switching.
4Device complexity
If a single connector type is used in the tuner apparatus, then the device structure is simple, but the apparatus cannot adapt to different digital broadcast transmission standards
Solution Approach 1:
The connector configuration is made dynamic rather than static. The switch device enables the apparatus to dynamically switch between different connector types (ATSC, DVB, ISDB) based on the detected broadcast standard. This dynamic reconfiguration capability allows the apparatus to adapt to different standards while maintaining a relatively simple base structure that can transform its connectivity configuration as needed.

AI summary
A global integrated tuner apparatus includes a switch device configured to selectively connect one of the plurality of connectors, a tuner device configured to tune a broadcast signal received through the connector selectively connected by controlling the switch device, and a controller configured to control the tuner device, wherein the controller may identify a set area when an external cable is connected to one of the plurality of connectors, control the tuner device such that the switch device is connected to a first connector of a type corresponding to a digital broadcast transmission standard of the set area, determine whether the first connector is normally connected by determining whether the tuner device has tuned the broadcast signal, and control the tuner device such that switch device is connected to a second connector of a different type from the first connector when the first connector is not normally connected.
