Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video encoding processes are time-consuming, especially for high-resolution and high-frame-rate videos, leading to significant delays and inefficiencies in multimedia content creation and distribution.
Innovation Solution
A video encoder system comprising a logic control module and an encoding module, which divides each frame into strips and distributes them across multiple video encoders for joint encoding, utilizing an NVENC hardware encoding engine and inter-frame prediction modules, allowing for efficient processing and real-time encoding of high-definition videos.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single video encoder processes high-resolution high-definition video, then encoding quality is maintained, but encoding time becomes excessively long and processing delay increases
Solution Approach 1:
The patent divides each video frame into multiple independent strips (e.g., top third, middle third, bottom third) and assigns different strips to different video encoders for parallel processing. This segmentation allows the encoding workload to be distributed across multiple encoders, significantly reducing the time required to encode high-resolution video while maintaining quality standards.
2Productivity
If multiple video encoders are used to process video frames in parallel, then encoding time is reduced, but coordination complexity and system complexity increase
Solution Approach 1:
The patent introduces a controller as an intermediary component that manages multiple video encoders. The controller receives control commands, distributes frame strips to appropriate encoders, and coordinates the parallel encoding process. This intermediary simplifies the complexity by centralizing the coordination logic, allowing multiple encoders to work in parallel without requiring complex peer-to-peer communication between them.
3Manufacturing precision
If video encoding is performed on high-frame-rate scenes, then video quality is improved, but processing difficulty and time consumption increase significantly
Solution Approach 1:
The patent segments high-frame-rate video processing into multiple parallel encoding streams, where each stream handles a portion of each frame. By dividing the processing workload across multiple encoders operating simultaneously, the system maintains high video quality for high-frame-rate content while reducing the processing difficulty and time consumption that would result from sequential processing.

AI summary
The present disclosure discloses a video encoder, a video encoding system and a video encoding method. The video encoder comprises a logic control module and an encoding module. Wherein, the logic control module is configured to receive a control command sent from an external controller for encoding a specified portion of each frame of image, and send the control command to the encoding module; and the encoding module is configured to receive the control command from the logic control module, and encode the specified portion of each frame of image according to the control command, so as to cooperate with a plurality of other video encoders to complete encoding each frame of image. By employing the video encoder, video encoding system and video encoding method according to the present disclosure, each frame of image can be accomplished jointly by a plurality of video encoders, thus significantly reducing the encoding time, diminishing the encoding latency, and achieving real-time encoding of high-definition video sources, in particular, video sources with a resolution ratio of 4 k or above.
