Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video encoding methods, such as the H.264 standard, are not suitable for real-time stream-typed video traffic as they require large granularity encoded picture data, which is not applicable for immediate frame-level data transmission in scenarios like video chatting.
Innovation Solution
A video encoding method and apparatus that processes original picture data to generate and encapsulate multimedia audio and video files in sequence, parsing and modifying data segments to achieve small granularity encoded picture data conforming to standards like H.264, utilizing multiple threads for efficient processing and outputting encoded data with sequence and picture parameter sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video encoding is performed using standard methods (H.264) with large granularity encoded picture data, then encoding compatibility and standard compliance are improved, but real-time stream-typed video traffic transmission capability deteriorates
Solution Approach 1:
The patent segments the encoded picture data by extracting individual frame data from the encoded bitstream. Instead of transmitting complete large-granularity encoded files, the system divides the data into frame-level segments that can be transmitted and processed independently in real-time, resolving the contradiction between standard compliance and real-time transmission capability
2Manufacturing precision
If video encoding processes complete video segments before output, then encoding quality and standard compliance are improved, but transmission delay increases
Solution Approach 1:
The patent performs preliminary encoding processing on individual frames as they are captured, rather than waiting to encode complete video segments. By preparing frame-level encoded data in advance and making it available for immediate transmission, the system reduces transmission delay while maintaining encoding quality through standard-compliant encoding processes
3Productivity
If small granularity frame-level encoded picture data is generated, then real-time stream-typed video traffic transmission is improved, but system compatibility with existing standards deteriorates
Solution Approach 1:
The patent extracts frame-level encoded picture data from the encoded bitstream by parsing and identifying frame boundaries and data structures. This extraction process retrieves small-granularity frame data while maintaining the standard-compliant encoding format, enabling real-time transmission without sacrificing system compatibility with existing video decoding systems
