Video Communication Format Negotiation via Invite Reply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video communication technologies face inefficiencies and low success rates due to inadequate negotiation mechanisms between terminals, leading to ineffective use of network resources and poor user experience.
Innovation Solution
A method and system where terminals negotiate and agree on a common video encoding/decoding format by sending an invite message with supported formats, determining the best match between the sending and receiving terminals, and using a default format if necessary, to establish successful video communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If terminals use fixed video encoding/decoding formats without negotiation, then device complexity is reduced, but video communication success rate deteriorates
Solution Approach 1:
The patent applies preliminary action by performing video format negotiation through invite and reply messages before actual video communication begins. The sending terminal sends an invite message with its supported formats, the receiving terminal replies with compatible formats, and both terminals determine a common format in advance, ensuring successful communication before resources are committed.
2Reliability
If terminals negotiate video encoding/decoding formats before communication, then video communication success rate is improved, but network resource consumption increases
Solution Approach 1:
The patent applies partial action by negotiating only the essential video encoding/decoding format parameters through invite and reply messages, rather than进行全面 system negotiation. This selective negotiation of specific format parameters reduces the overhead compared to comprehensive protocol exchanges while still ensuring compatibility.
3Ease of operation
If terminals negotiate video encoding/decoding formats, then user experience is improved, but communication time increases
Solution Approach 1:
The patent applies preliminary action by performing video format negotiation through invite and reply messages before actual video communication begins. The sending terminal sends an invite message with its supported formats, the receiving terminal replies with compatible formats, and both terminals determine a common format in advance, ensuring successful communication before resources are committed.
4Adaptability or versatility
If terminals use incompatible video encoding/decoding formats, then device adaptability is reduced, but processing efficiency is improved
Solution Approach 1:

AI summary
A video communication method and system, and a terminal are presented. A sending terminal sends an invite message to a receiving terminal. The sending terminal receives a reply message. The sending terminal determines that a video encoding/decoding format supported by the sending terminal does not include a video encoding/decoding format included in the reply message. The sending terminal obtains a video encoding/decoding format supported by both the sending terminal and the receiving terminal. The sending terminal performs video communication with the receiving terminal by using the obtained video encoding/decoding format.
