Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If portable electronic devices use carrier specific chipsets and applications to process digital video broadcasts, then the devices can receive and display broadcasts on mini-displays, but the reception and display resolution is limited
Solution Approach 1:
The patent introduces a portable media player as an intermediary device between the digital video broadcast transmission and the portable electronic device. The media player receives the broadcast signal, processes it using its own processing resources, and then outputs the processed video to the portable electronic device's display. This mediator approach allows the portable device to display higher resolution content without requiring the device itself to have powerful processing capabilities.
Solution Approach 2:
The patent creates a copy of the processed video signal from the portable media player and transmits it to the portable electronic device. Instead of requiring the portable device to process the original broadcast signal directly, the system creates a processed copy that can be displayed on the device's screen. This copying mechanism enables the display of higher resolution content than the device's native processing capabilities would otherwise allow.
2Use of energy by moving object
If portable electronic devices use limited processing resources, then the devices can maintain portability, but the ability to process and display high-resolution digital video broadcasts is restricted
Solution Approach 1:
The portable media player serves as an intermediary that performs the energy-intensive processing of digital video broadcasts. By offloading the processing tasks to the media player, the portable electronic device can maintain its portability and limited resource consumption while still benefiting from high-resolution video output. The media player handles the computationally demanding tasks of receiving, decoding, and processing the broadcast signal.
Solution Approach 2:
The system segments the processing tasks between two devices: the portable media player handles the resource-intensive broadcast reception and processing, while the portable electronic device handles only the display function. This segmentation allows each device to operate within its resource constraints while achieving overall high-resolution video display capability.
Data Source
AI summary
A system and method of accessing digital video broadcasts within an information handling system is disclosed. In one form, a digital video broadcast processing system can include a digital video broadcast receiver module operable to process a first digital video broadcast data received within a multiple channel digital video broadcast signal and to output the first digital video broadcast data to an interconnect bus of a computer system. The digital video broadcast processing system can also include a communication interface operable to be removeably coupled to an interconnect bus interface of the computer system. The communication interface can be operable to communicate the first digital video broadcast data, including an interconnect dependent data format, from the digital video broadcast receiver module to a digital video processing application of the computer system.
