Terminal Codec Selection via Measured Network Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting codecs for audio and/or video data transmission over packet switching connections do not adequately consider available network capacity, leading to suboptimal quality and requiring significant configuration efforts.
Innovation Solution
A method that uses a table to determine the codec list based on measured transmission capacity, with automatic updates and consideration of address ranges, allowing for dynamic selection and adaptation of codecs during active connections without interrupting service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If codec selection is based on static address ranges with pre-configured codec lists, then adaptation to network capacity is improved, but configuration expenditure and device complexity increase significantly
Solution Approach 1:
The terminal automatically performs measurements to determine transmission capacity and dynamically updates its own codec list without requiring external configuration or manual intervention. The system serves itself by autonomously adapting to network conditions through self-measurement and self-configuration
Solution Approach 2:
The codec list is dynamically adjusted based on measured transmission capacity parameters. Instead of using static pre-configured lists, the system changes the codec selection parameters in real-time according to the actual network capacity detected through measurements
2Device complexity
If codec selection ignores available network capacity, then configuration complexity is reduced, but transmission quality and reliability deteriorate
Solution Approach 1:
The system continuously measures the actual transmission capacity and uses this feedback information to dynamically adjust the codec list. The measurement results feed back into the codec selection process, ensuring that the chosen codec always matches the current network capacity for optimal quality
Solution Approach 2:
The terminal performs capacity measurements and prepares an appropriate codec list before the actual data transmission begins. This preliminary action ensures that the codec selection is optimized for the current network conditions before communication starts, preventing quality issues

AI summary
The invention relates to a method for selecting a codec for transmission of audio and/or video data between terminals (1, 3) through a packet switching connection (2), the terminals (1, 3) selecting the codec from a codec list, characterized in that the codec list for a new connection is determined by means of a table in which for at least one destination address range, the associated transmission capacity is indicated and the table is automatically updated through measurements, as well as a terminal for carrying out the method.
