Broadcasting Segment File Sequence Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting systems face challenges in creating a continuous test environment for segment-based broadcasting content with limited capacity, leading to interruptions and discontinuities, especially when transitioning to next-generation broadcasting technologies like segment and IP-based systems.
Innovation Solution
An apparatus and method that corrects the sequence numbers and media decode times of segment files to ensure continuous reproduction, using a storage system, correcting units, and file processing to generate output segment files with updated configuration and media information, simulating a continuous broadcast environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If segment based broadcasting contents with limited capacity are repeatedly transmitted, then the test environment cost is reduced, but the reproduction continuity is disrupted causing interruptions
Solution Approach 1:
The patent changes the time parameters (sequence numbers and media decode times) of the segment files to ensure continuous reproduction. By correcting these temporal parameters to be continuously increased across repeated transmissions, the system maintains the illusion of continuous broadcast while using limited capacity content for testing
Solution Approach 2:
The patent creates corrected copies of the original segment files with modified sequence numbers and media decode times. These corrected output segment files are generated by copying the original structure but adjusting the temporal parameters to eliminate interruptions during repeated transmission
2Reliability
If MPEG-2 TS is used to solve stream interruption, then the stream continuity is improved, but the adaptability to next-generation segment and IP based broadcasting is reduced
Solution Approach 1:
The patent segments the broadcasting content into separate segment files with corrected temporal parameters. By dividing the content into manageable segments and independently correcting their sequence numbers and media decode times, the system achieves continuity without relying on MPEG-2 TS while maintaining compatibility with next-generation segment and IP based broadcasting standards
3Productivity
If the same limited capacity test stream is repeatedly transmitted, then the testing efficiency is improved, but the test environment realism is reduced due to visible interruptions
Solution Approach 1:
The patent modifies the temporal parameters (sequence numbers and media decode times) of repeatedly transmitted test segments to ensure continuous reproduction. This allows efficient repeated use of limited test content while maintaining a realistic continuous broadcast environment for accurate testing of next-generation broadcasting systems

AI summary
The present invention relates to a method and an apparatus for transmitting broadcasting contents which repeatedly transmits segment based broadcasting contents to easily develop next generation broadcasting service and system so that it looks as if the contents are continuously reproduced even when contents having a limited capacity are repeatedly reproduced and a test environment which is the same as an actual broadcasting environment is provided.
