Multipoint Control Unit Automatic Audio Video Bitstream Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conference recording methods require manual browsing and editing to identify and record specific audio and video streams, leading to high costs and low efficiency.
Innovation Solution
A method and apparatus that use feature information, such as picture or sound information, to automatically determine the relevant audio video bitstream for recording, allowing the multipoint control unit to selectively send the appropriate streams to the recording server, eliminating the need for manual screening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual browsing and editing is used to identify and record specific audio and video streams, then recording accuracy can be controlled, but manual costs are high and recording efficiency is low
Solution Approach 1:
The system automatically identifies and selects audio-video bitstreams for recording based on feature information matching, eliminating the need for manual browsing and editing operations. The recording server autonomously determines which streams to record by comparing feature information of participants with the audio-video streams received from site terminals.
Solution Approach 2:
The manual mechanical process of browsing and editing audio-video streams is replaced with an automated information processing system that uses feature information matching algorithms to automatically identify and select streams for recording, substituting human operation with computational analysis.
2Reliability
If entire conference audio video streams are recorded, then complete conference content is preserved, but storage requirements and processing complexity increase
Solution Approach 1:
The system extracts and selects only the specific audio-video bitstreams that correspond to participants who need to be recorded, rather than recording entire conference streams. By extracting relevant streams based on feature information matching, the system reduces storage requirements and processing complexity while maintaining recording completeness for the required participants.
Solution Approach 2:
The conference audio-video streams are segmented into individual participant streams, and only the segments corresponding to participants who meet the recording criteria are selected for recording. This segmentation approach allows selective recording of relevant content while avoiding the complexity of processing entire conference streams.
3Productivity
If feature information matching is used to automatically determine audio video bitstreams, then recording efficiency improves and manual costs reduce, but system complexity increases
Solution Approach 1:
The feature information matching mechanism serves multiple functions: it identifies participants, selects audio-video streams, and determines recording requirements. By making the system multi-functional, the patent reduces the need for separate complex subsystems while maintaining high recording efficiency and reducing manual costs.

AI summary
A conference recording method includes: A multipoint control unit determines, based on feature information of a person, an audio video bitstream that needs to be recorded, from audio video bitstreams sent by site terminals. The feature information includes picture information or sound information. The multipoint control unit sends, to a recording server, the audio video bitstream that needs to be recorded, so that the recording server performs conference recording. The feature information of the person is used to implement automatic screening on the audio video bitstream that need to be recorded.
