Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
MPEG-2 TS has limitations such as one-way communication, inefficient transmission due to fixed frame size, and generation of unnecessary overheads when using Internet Protocol and specialized audio/video transmission protocols, which hinder effective multimedia service support in heterogeneous networks.
Innovation Solution
The proposed solution involves configuring a multimedia frame for transmission through a heterogeneous network by generating header information with a frame identifier and quality of service information, and combining it with multimedia data to create a multimedia frame that can be transmitted efficiently over an IP-based network using the MMT standard, enabling hybrid content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MPEG-2 TS is used for transmitting multimedia content in broadcast network, then transmission reliability in error-prone environment is improved, but transmission efficiency deteriorates due to fixed frame size and unnecessary overheads
Solution Approach 1:
The patent segments the fixed MPEG-2 TS frame structure into variable-size packets adapted to IP network requirements. Each packet contains a payload length field that dynamically specifies the size of multimedia data, allowing efficient utilization of network bandwidth while maintaining the error-resilient transport characteristics of MPEG-2 TS through adaptive packetization.
2Ease of operation
If fixed frame size is used in MPEG-2 TS transmission, then synchronization is simplified, but transmission efficiency deteriorates due to inability to adapt to variable data sizes
Solution Approach 1:
The patent introduces dynamic packetization where each packet's payload length is explicitly indicated in the header. This allows the transmission system to adapt packet sizes according to the actual multimedia data size, achieving both efficient bandwidth utilization and simplified synchronization through clear length delimiters that enable easy packet boundary detection.
3Adaptability or versatility
If MPEG-2 TS protocol is used with IP and specialized audio/video protocols, then comprehensive multimedia service support is improved, but system complexity increases due to multiple protocol layers and overheads
Solution Approach 1:
The patent creates a universal packet structure that integrates MPEG-2 TS transport capabilities with IP network requirements in a single protocol layer. The packet format includes fields for payload length, sequence numbering, and error resilience mechanisms, eliminating the need for separate specialized audio/video protocols and reducing overall system complexity while maintaining comprehensive multimedia service support.
