Wireless Playback Control Device Priority Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia systems face challenges in integrating various video playback mechanisms and data transmission technologies to manage multiple wireless image data types effectively, particularly in determining playback priorities when multiple requests are received.
Innovation Solution
A playback control device with an RF front end and controller is configured to receive and process playback requests based on priority, arbitrating which data types to play back on a display device, allowing for efficient management of multiple wireless multimedia data types by transmitting grant or rejection messages to video client devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless video playback mechanisms and data transmission technologies are integrated into a single multimedia system, then the system's adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The patent segments the multimedia system into distinct functional modules: a reception module that receives playback requests with priority information, a playback control module that manages playback based on priority arbitration, and a transmission module that handles data transfer. This modular segmentation allows multiple wireless video technologies to be integrated while maintaining manageable complexity through clear separation of concerns.
2Productivity
If priority-based arbitration is implemented for multiple wireless multimedia data types, then the productivity and efficiency of data transmission are improved, but the device complexity increases
Solution Approach 1:
The patent implements preliminary action by embedding priority information within playback request messages before transmission. The system pre-establishes priority levels for different wireless multimedia data types, allowing the playback control module to make rapid arbitration decisions without complex real-time analysis. This preliminary classification simplifies the control logic while maintaining high transmission efficiency.
3Reliability
If concurrent playback requests from multiple video client devices are managed with priority arbitration, then the reliability of playback service is improved, but the loss of time in processing requests increases
Solution Approach 1:
The patent changes the parameter of request messages by incorporating priority level information as a key attribute. This parameter change allows the playback control module to use simple priority comparison rather than complex arbitration algorithms, significantly reducing request processing time while ensuring reliable playback service through systematic priority-based decision making.
Data Source
AI summary
A method and a playback control device are provided. The method, performed by the playback control device, includes: receiving a first request to playback a first data of a first wireless multimedia data type having a first priority; and playing back the first data if no other data of a wireless multimedia data type having a priority higher than the first priority is received.
