Segmented Multimedia Encoding for Buffer Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia encoding technologies face challenges in efficiently encoding digital content to meet multiple decoder buffer models without requiring a full re-encode of the entire stream, especially when dealing with complex encoding standards like AVC and VC1, which demand compliance with multiple buffer models, leading to increased processing time and reduced productivity.
Innovation Solution
The proposed method involves segment-based re-encoding, where only specific segments of encoded content are identified and re-encoded to comply with decoder buffer models, using a system that evaluates and modifies buffer models to ensure compliance with multiple decoder standards like AVC and VC1, allowing for accelerated encoding while maintaining quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full re-encoding of the entire stream is performed to comply with multiple decoder buffer models, then compliance with decoder standards is improved, but processing time increases and productivity decreases
Solution Approach 1:
The patent divides the encoded content stream into multiple segments and identifies only the specific segments that fail to comply with decoder buffer models. Instead of re-encoding the entire stream, the system re-encodes only these identified segments, thereby reducing processing time while maintaining compliance with multiple decoder standards (AVC and VC1).
Solution Approach 2:
The system evaluates encoded segments against multiple buffer models and changes encoding parameters selectively for segments that fail compliance. By analyzing buffer model violations and adjusting parameters only where necessary, the system achieves compliance without requiring full stream re-encoding, thus resolving the contradiction between reliability and processing time.
2Reliability
If full re-encoding is performed to meet multiple buffer model requirements, then encoding compliance is improved, but encoding time increases
Solution Approach 1:
The patent segments the encoded content into manageable portions and systematically identifies only the segments that violate buffer model requirements. This segmentation allows the system to re-encode only the problematic segments rather than the entire stream, thereby maintaining encoding compliance while improving encoding speed and productivity.
Solution Approach 2:
The system incorporates feedback mechanisms that evaluate encoded segments against multiple buffer models and identify compliance failures. This feedback loop enables selective re-encoding of only the segments that need correction, optimizing the balance between compliance and encoding speed without requiring full stream re-processing.
3Productivity
If segment-based re-encoding is used to reduce processing time, then productivity is improved, but complexity of identifying and evaluating segments increases
Solution Approach 1:
The patent implements segmentation of the encoded stream into discrete segments that can be independently evaluated and re-encoded. This segmentation strategy simplifies the overall process by breaking down the complex task of multi-buffer-model compliance into manageable unit evaluations, thereby improving productivity without proportionally increasing complexity.
Solution Approach 2:
The system performs preliminary evaluation of encoded segments against multiple buffer models to identify compliance failures before initiating re-encoding. This preliminary action filters out only the problematic segments, reducing the complexity of the overall process by avoiding unnecessary evaluation of compliant segments and enabling efficient selective re-encoding.
Data Source
AI summary
The present embodiments provide methods, apparatuses, systems for use in encoding and/or formatting content, such as multimedia content. Some embodiments provide methods for use in encoding content. These methods receive source content, encode the source content producing encoded content, evaluate a first encoded segment of the encoded content relative to a plurality of buffer models, determine whether the first segment of encoded content is to be re-encoded relative to one or more of the plurality of buffer models based on the evaluation; and re-encode the first segment when it is determined that the first segment is to be re encoded.
