Media Streaming Device Antenna Radiation Pattern Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference between media streaming devices and other audiovisual content sources, such as television tuners, occurs when connected to the same display device, leading to degraded or interrupted content display, and increased maintenance costs.
Innovation Solution
The media streaming device implements mitigation protocols by suspending non-active modules, such as the HDMI module, and adjusting antenna radiation patterns to direct away from the display device and tuner, reducing interference when not actively streaming content, and reverting when streaming resumes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the media streaming device remains active to provide content streaming capability, then the device can quickly resume streaming when needed, but interference with television tuner and display device occurs
Solution Approach 1:
The patent applies dynamics by making the antenna radiation pattern adjustable and reconfigurable. The system dynamically switches between a first radiation pattern (when streaming is active) and a second radiation pattern (when streaming is inactive but device remains connected), allowing the same hardware to adapt its behavior based on operational state without physical modification.
Solution Approach 2:
The patent changes the radiation pattern parameter of the antenna system based on streaming activity state. When content streaming is detected as inactive, the system transitions to a second radiation pattern that directs signals away from the display device and television tuner, thereby reducing interference while maintaining the ability to quickly resume streaming.
2Adaptability or versatility
If multiple audiovisual content sources are connected to the same display device, then content variety is increased, but interference between devices occurs leading to degraded display quality
Solution Approach 1:
The patent applies local quality by creating directionally selective signal transmission. The antenna system is configured to transmit signals in specific directions (away from the display device when not actively streaming) rather than omnidirectionally, allowing coexistence of multiple devices by localizing the interference problem to specific spatial zones rather than affecting the entire system.
3Ease of operation
If the media streaming device is kept connected to the display device for quick access, then convenience is improved, but device failures and maintenance costs increase due to continuous interference
Solution Approach 1:
The patent implements periodic action by monitoring the streaming activity state and periodically adjusting the antenna radiation pattern accordingly. The system transitions between radiation patterns based on whether streaming is actively detected, creating a rhythmic on-off pattern of interference that correlates with actual usage rather than continuous interference.

AI summary
Systems, methods, and computer-readable media are disclosed for streaming media content. The systems, methods, and computer-readable media described herein may improve user experiences and reduce device failures by mitigating problems between devices. In an example method described herein, a media streaming device may be connected to a display device in order to facilitate streaming of content. A processing apparatus of the media streaming device may determine that the display device is not presenting content streamed from the media streaming device and in turn switch the antenna radiation pattern from a first pattern to a second pattern.
