Media Fragment Unit Header Encoding for Hybrid Media Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for receiving hybrid media contents are inefficient, as they require manual selection for self-diagnosis and lack a systematic approach for optimizing transmission and reception using various transmission units.
Innovation Solution
A method for receiving media content in a multimedia system that utilizes a data stream with a transmission unit, such as a Media Unit (M-Unit) or Media Fragment Unit (MFU), which includes a count value and priority information in its header, allowing for efficient processing and decoding of subsequent units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hybrid media contents are separated into multiple multimedia contents and reconstructed at the reception side, then the media content can be efficiently transmitted and received, but the system complexity increases due to manual selection requirements and lack of systematic processing approach
Solution Approach 1:
The patent segments media contents into multiple transmission units (M-Units and MFUs) with hierarchical structure. Each unit is independently processable with its own header containing necessary control information, enabling parallel processing and reducing system complexity while maintaining transmission efficiency
Solution Approach 2:
The patent applies preliminary action by embedding count values and priority information in the headers of transmission units before transmission. This allows the reception side to automatically process units in the correct sequence without manual intervention, resolving the contradiction between efficient transmission and system complexity
2Productivity
If transmission units include count values and priority information in headers, then decoding efficiency is improved, but the data overhead increases
Solution Approach 1:
The patent applies partial action by including count values and priority information only in specific transmission units where needed (e.g., first MFU of each M-Unit), rather than duplicating all information in every unit header. This reduces overall data overhead while maintaining decoding efficiency
Solution Approach 2:
The patent organizes transmission units in a hierarchical structure (M-Units containing multiple MFUs) adding a dimensional organization to the data flow. This allows efficient processing through structural relationships rather than requiring extensive information in each individual unit header

AI summary
A method for receiving a media content by an apparatus in a multimedia system, the method comprising receiving, through a communication network, a data stream comprising data for a transmission unit which comprises at least a part of media data related to the media content, wherein the transmission unit is one of a media unit, a media fragment unit (705), MFU, which is a fragment of the media unit, or a fragment of the MFU (705), and processing the received data stream, wherein if the transmission unit is the MFU (705), the MFU (705) comprises a count value indicating a number of at least one subsequent MFU of which decoding is processed dependently based on the MFU (705), and information indicating a priority of the MFU (705) relative to another MFU within the media unit, and wherein the count value and the information indicating the priority are included in a header of the MFU (705).
