Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protocols and standards for communicating and formatting video-based protected content are inadequate for achieving interoperability among new technologies, protocols, and standards, particularly for high-efficiency compression methods used in video distribution over communication networks.
Innovation Solution
The development of encoding and decoding systems and methods that utilize JPEG 2000 Part 1 (J2K) as the content formatting standard and MPEG-2 Part 1 Systems Section as the communications protocol, enabling the encoding of frames of image data into packetized elementary streams (PES) and subsequent decoding to ensure interoperability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new content formatting standards and communication protocols are implemented to accommodate technological changes, then adaptability and versatility are improved, but interoperability among different systems deteriorates
Solution Approach 1:
The patent introduces an intermediary layer that translates between different content formatting standards (such as JPEG 2000 and MPEG-2) and communication protocols. This mediator enables systems using different standards to interoperable by converting data formats and protocols, thus maintaining interoperability while allowing adoption of new technologies.
Solution Approach 2:
The system is designed with multi-functional capabilities to handle multiple content formatting standards and communication protocols simultaneously. By making the system universal and capable of working with various standards (JPEG 2000, MPEG-2, H.264, etc.), it maintains interoperability across different technological platforms while adapting to new standards.
2Productivity
If high efficiency compression methods are used to enable transport through communication networks, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the video content into multiple frames and further divides each frame into manageable units that can be independently compressed and transmitted. This segmentation allows the use of sophisticated compression algorithms on smaller data units, improving overall transport efficiency while managing complexity through modular processing.
Solution Approach 2:
The system performs preliminary compression and formatting of video content before transmission through communication networks. By pre-processing the video data using high-efficiency compression methods and organizing it into appropriate formats (such as PES packets), the system achieves better transport efficiency while reducing the complexity burden on receiving systems.
