Innovation Solution
A system integrating a satellite receiver and cellular antenna with a satellite receiver STB, equipped with both satellite and cellular chipsets, to process and transmit broadcast and cellular signals, enabling cellular properties such as phone call, Internet, and SMS support, as well as emergency alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite receiver STB is used for broadcast signals, then video feed reception is enabled, but cellular properties such as phone call, Internet, and SMS support are lost
Solution Approach 1:
The patent combines satellite receiver and cellular antenna into a single STB device, integrating broadcast signal reception and cellular signal processing in one unit. The STB circuit board includes both satellite broadcast chipset and cellular chipset, allowing the device to provide both video feed and cellular properties (phone call, Internet, SMS) simultaneously, thereby improving service capability while managing system complexity through unified design.
Solution Approach 2:
The STB device is designed to perform multiple functions: receiving broadcast signals from satellite, receiving cellular signals from cellular towers, processing both signal types, and transmitting to respective end user devices. This multi-functional design enables a single device to replace what would traditionally require separate satellite receiver and cellular modem, improving adaptability while the integrated architecture manages complexity.
2Reliability
If satellite broadcast chipset processes broadcast signals, then video feed un-encapsulation is achieved, but cellular signal processing capability is reduced
Solution Approach 1:
The STB circuit board is segmented into distinct functional modules: satellite broadcast chipset for processing broadcast signals and un-encapsulating video feed, and cellular chipset for processing cellular signals. This segmentation allows each chipset to specialize in its respective signal type, ensuring reliable processing while maintaining overall system versatility through the combination of both specialized modules.
