Wireless Media Streaming Transmission Strategy Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless transmission of media presentations to remote devices is costly and lacks user control over transmission strategies, leading to varying signal quality issues that affect the user's experience, such as jerky streams and artifacts due to poor reception.
Innovation Solution
A method and system that adjust the transmission strategy based on usage data, including location and signal quality, by allowing user input through a user interface to optimize the balance between media presentation quality and cost, involving adjustments in error-correction bits, buffering, and pre-loading transmitters, to maintain a desired quality and cost tradeoff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used to deliver media presentations to remote devices, then user mobility and accessibility are improved, but transmission costs increase significantly compared to wired connections
Solution Approach 1:
The system dynamically changes transmission parameters (error-correction bits, buffer sizes, data rate) based on signal quality conditions to optimize the balance between maintaining acceptable media quality and reducing transmission costs. When signal quality is good, the system reduces error-correction overhead and buffering requirements, thereby lowering transmission costs while maintaining usability.
2Reliability
If transmission strategy is adjusted dynamically based on signal quality, then media presentation quality is improved, but system complexity increases due to need for monitoring and adjusting multiple parameters
Solution Approach 1:
The system implements feedback mechanisms where the remote device monitors signal quality and transmits this information back to the media server. The server then automatically adjusts transmission parameters based on this feedback, creating a closed-loop control system that maintains media quality without requiring complex manual intervention or overly sophisticated local processing at the remote device.
Solution Approach 2:
The remote device autonomously monitors its own signal quality conditions and reports them to the server, which then self-adjusts the transmission strategy. This distributes the intelligence and decision-making across the system rather than concentrating complexity in one location, simplifying individual components while maintaining overall system sophistication.
3Reliability
If more error-correction bits are transmitted to improve reception quality, then signal reliability is improved, but transmission data volume and costs increase
Solution Approach 1:
The system applies error-correction bits partially rather than excessively - it transmits the minimum necessary amount of error-correction overhead based on current signal conditions. When signal quality is good, error-correction bits are reduced to the essential minimum, and when signal quality deteriorates, the system increases error-correction overhead only to the extent needed to maintain acceptable reliability, avoiding unnecessary data volume increases.

AI summary
A method, system and computer program and method for delivering a streaming data to a remote device from a wireless transmitter. In one embodiment, a transmitter is configured to send units of the streaming data to the remote device. A receiver is configured to receive usage data about the streaming data from the remote device. An adjusting module is configured to automatically adjust a transmission strategy of unsent units of the streaming data based, at least in part, on the usage data as a function of time according to a transmission policy. The usage data may include at least location information about the remote device or time of day information at the remote device. A user interface at the remote device may be configured to adjust the predefined transmission policy.
