Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In contemporary communication systems, payload data transmission via packet-oriented networks often results in quality losses and delays due to multiple conversions and encoding/decoding processes, especially when IP terminals and gateways use incompatible encoding methods.
Innovation Solution
A method and system that verify compatibility between encoders and decoders in network devices to select the most suitable converting device for payload data transmission, allowing data to bypass non-compatible devices and minimize quality losses, using a server device and converting devices to manage codec compatibility and optimize encoding/decoding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If payload data is transmitted via multiple gateways with multiple encoding/decoding conversions, then the payload data can reach the destination through incompatible networks, but the quality of payload data deteriorates due to multiple conversions and buffering
Solution Approach 1:
The patent applies preliminary action by verifying encoder-decoder compatibility between source and target communications devices before establishing the payload data transmission path. The server device checks whether the target device can decode the source device's encoded payload data, and only if incompatible, selects an intermediate converting device. This preliminary verification prevents unnecessary conversions and buffering, thereby maintaining payload data quality while ensuring network compatibility.
2Adaptability or versatility
If multiple converting devices are used to bridge incompatible encoding methods, then network connectivity is achieved, but transmission delays increase due to buffering at each gateway
Solution Approach 1:
The server device performs preliminary verification of encoder-decoder compatibility before payload data transmission. By checking in advance whether the target communications device can directly decode the source device's encoded data, the system avoids unnecessary routing through intermediate converting devices, thereby minimizing buffering delays and reducing overall transmission time.
Solution Approach 2:
The patent extracts the essential function of compatibility verification from the traditional multi-gateway conversion process. Instead of routing payload data through multiple gateways for potential conversion, the system separates the verification function (performed by the server) from the transmission function, allowing direct transmission when compatible and selective conversion only when necessary.
3Adaptability or versatility
If payload data is buffered at each gateway for encoding and decoding, then incompatible encoding methods can be bridged, but the quality of payload data deteriorates particularly when compressing codecs are used
Solution Approach 1:
The server device performs preliminary verification of codec compatibility before transmission. By checking whether the target communications device can directly decode the source device's encoded payload data, the system avoids unnecessary buffering and conversion operations. This prevents information loss that would occur during compression and decompression cycles, particularly when using compressing codecs.
4Productivity
If a direct connection is established between IP terminals with compatible encoders and decoders, then transmission efficiency is improved, but adaptability to incompatible networks is reduced
Solution Approach 1:
The patent introduces a server device as an intermediary that mediates between source and target communications devices. The server verifies encoder-decoder compatibility and, when incompatible, selects an intermediate converting device to bridge the connection. This intermediary approach maintains direct transmission paths when possible (preserving efficiency) while enabling indirect paths through converting devices when needed (ensuring interoperability).
Solution Approach 2:
The system dynamically adjusts the transmission path based on verified compatibility. When the target device can directly decode the source device's encoded data, a direct efficient path is used. When incompatible, the path dynamically routes through an intermediate converting device. This dynamic adaptation optimizes both transmission efficiency and network interoperability.

AI summary
There is described a transmission of user data from a source communications device provided with a first encoder for encoding users data to a target communications device provided with a first decoder for decoding said user data via a communication network which is provided with several converting devices comprising additional encoders and additional decoders for carrying out a verification of the converting devices. Via the verification it is determined, whether the first encoder is compatible with the decoder of a given converting device and, whether the first decoder is compatible with the encoder of said converting device. One of the converting devices for which the compatibility is ascertained by the verification is selected for transmitting user data. During transmission of the user data, said user data encoded with the aid of the first encoder is decoded with the aid of the compatible decoder of the converting device and the user data decodable with the aid of the first decoder is encoded with the aid of the compatible encoder of the selected converting device.
