Composite Multi-View Streaming for Fast Live Channel Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face difficulties in providing live video services to multiple clients through multiple channels in real-time due to limitations in encoding and transmitting multiple videos, leading to inefficiencies in network resource usage and synchronization issues during channel switching.
Innovation Solution
A method and system that synthesizes multiple channel videos into a single composite video, allowing for a multi-view playback mode, with the ability to switch between multi-view and full-view modes while maintaining audio and video synchronization, using a single stream to minimize network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple videos from multiple channels are encoded and transmitted in real time, then live video service can be provided to multiple clients, but network resource usage increases and system complexity increases
Solution Approach 1:
The patent merges multiple channel videos into a single composite video stream by synthesizing them together. This allows the system to transmit multiple channel contents through one unified stream rather than maintaining separate streams for each channel, thereby reducing network resource consumption while preserving multi-channel service capability.
Solution Approach 2:
The single composite video stream serves multiple functions by containing synchronized video content from multiple channels. This universal stream can be distributed to multiple clients and can be switched between channels, eliminating the need for separate dedicated streams for each channel and reducing overall network resource usage.
2Adaptability or versatility
If multiple videos from multiple channels are encoded and transmitted in real time, then live video service can be provided to multiple clients, but device complexity increases
Solution Approach 1:
The patent combines multiple channel videos into a single composite stream, which simplifies the encoding and transmission system architecture. Instead of managing multiple independent encoding and transmission pipelines, the system uses one unified pipeline that handles all channels, thereby reducing device complexity while maintaining multi-channel functionality.
Solution Approach 2:
The single composite video stream performs multiple functions by carrying content from multiple channels simultaneously. This universal approach eliminates the need for separate processing systems for each channel, reducing overall system complexity while preserving the ability to provide live video services across multiple channels.
3Ease of operation
If channel switching is implemented in multi-live transmission environment, then users can switch between channels, but audio and video synchronization issues occur
Solution Approach 1:
The patent merges audio and video content from multiple channels into a single synchronized composite stream. This unified structure ensures that audio and video remain synchronized across channel switches because they are processed together as one integrated stream, eliminating synchronization issues that would arise from separate processing of audio and video channels.
4Loss of energy
If a single composite video is used to represent multiple channels, then network resources are minimized, but the ability to provide high-resolution original video to users is reduced
Solution Approach 1:
The single composite video stream serves as a universal carrier that can provide differentiated quality experiences to different users. While the composite stream uses minimal network resources, the system can selectively extract and provide high-resolution original video content to users who require it, making the single stream serve both bandwidth-efficient and high-quality delivery functions.

AI summary
A method, a system, and a computer-readable recording medium implement a fast-switching mode between channels in a multi-live transmission environment. A composite image in which images of multiple channels are synthesized into one image in a live transmission environment is received as one stream to configure a multi-view composed of the images of the multi-channels and, as an image of a specific channel is selected in the multi-view, the original image of the specific channel is received and the multi-view may be switched to a full-view of the image of the specific channel.
