Endpoint Video Recording Without MCU
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing systems require expensive and complex multipoint control units (MCUs) for processing and recording multiple video streams, making them unsuitable for small enterprises or individuals, and existing recording methods can only record one stream at a time, limiting immersive recording capabilities.
Innovation Solution
A method and device that process media data into unified coding formats, allowing for recording in continuous presence mode to save media data from multiple endpoints and lecture mode to save data from a designated lecturer, eliminating the need for MCUs and enabling simultaneous recording of all video content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a MCU is used to process and record multiple video streams, then recording capability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the recording function from the complex MCU system and implements it directly at the endpoint devices. Each endpoint independently records its own video stream using its built-in recording capabilities, eliminating the need for a centralized MCU to perform recording operations. This extraction of the recording function resolves the contradiction by providing recording capability without requiring complex MCU infrastructure.
Solution Approach 2:
The patent enables endpoints to record their own video streams independently without requiring external control from a MCU. Each endpoint autonomously captures and stores its video data, making the system self-sufficient for recording purposes. This self-service approach eliminates the need for expensive MCUs while maintaining full recording functionality across all participants.
2Adaptability or versatility
If a MCU is used to manage video conferences, then conference management capability is improved, but cost increases making it unsuitable for small users
Solution Approach 1:
The patent implements a decentralized architecture where endpoints autonomously manage their own video streams and recording operations without requiring centralized MCU control. Each endpoint independently handles conference participation, video capture, encoding, and recording, eliminating the need for expensive MCU infrastructure. This self-service model enables small users and individuals to conduct video conferences and recordings without significant investment in MCU equipment.
Solution Approach 2:
The patent segments the conference management function across multiple independent endpoints rather than consolidating it in a single MCU. Each endpoint independently manages its own video stream, encoding parameters, and recording operations. This segmentation distributes the management capability across the system, eliminating the need for a centralized expensive MCU while maintaining full conference management functionality at each participant's location.
3Adaptability or versatility
If traditional recording methods are used, then recording function is provided, but only one stream can be recorded at a time limiting immersive recording
Solution Approach 1:
The patent segments the recording function across multiple independent endpoints, with each endpoint recording its own video stream simultaneously. Instead of a single system recording one stream, multiple endpoints each capture and record their respective streams in parallel. This segmentation enables simultaneous multi-stream recording, providing immersive recording capability of all conference participants without the limitation of single-stream recording.
Data Source
AI summary
A method of video conferencing among two or more video conference endpoints is provided, wherein the method comprises steps of: processing media data of the video conference into unified coding formats while switching media data of the video conference between the two or among more video conference endpoints; and saving the processed media data into recording files of continuous presence mode and lecture mode, wherein the recording file of continuous presence mode saves media data generated by the two or more video conference endpoints, the recording file of lecture mode saves media data generated by a video conference endpoint who is the lecturer in the video conference. Accordingly, a device of video conferencing is provided.
