Solution Overview

Problem

Conventional multimedia systems fail to precisely configure fragmentation information for multimedia data units, leading to inefficient data transmission and reception due to the lack of consideration for data unit and fragment sizes during fragmentation.

Innovation Solution

The method involves configuring and transmitting fragmentation information for multimedia data units, including fragment type, indicator, and counter, to accurately reassemble data packets into complete multimedia data units at the receive end, using techniques such as fragment counter reuse and aggregation flags to handle varying fragment counts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If one data unit is split into multiple fragments without considering data unit size and fragment size, then data transmission can proceed, but fragmentation information cannot be precisely configured

Engineering Contradiction:
Improvefragmentation information precisionVSAvoidfragmentation configuration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the fragmentation information into distinct components: fragment type (indicating first, mid, or last fragment), fragment indicator (position within data unit), and fragment counter (number of fragments). This segmentation allows precise configuration of fragmentation information while maintaining manageable complexity through structured organization of the information elements.

Inventive Principle:
Principle #1Segmentation

2Productivity

If fragmentation information is configured without considering network characteristics and data properties, then transmission can occur, but transmission efficiency is reduced

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidfragmentation information accuracy
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent changes the parameters of fragmentation information configuration by introducing fragment type, fragment indicator, and fragment counter that adapt to different data unit sizes and network conditions. This allows the system to optimize fragmentation for various scenarios (HD, 4K, 8K formats) while maintaining accurate tracking of fragment positions and counts, thereby improving transmission efficiency without losing fragmentation information accuracy.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If conventional fragmentation methods are used, then data can be transmitted, but the system cannot handle varying data sizes (HD, 4K, 8K) effectively

Engineering Contradiction:
Improvedata size adaptabilityVSAvoiddata reconfiguration precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent creates a universal fragmentation information configuration that works across multiple data sizes (HD, 4K, 8K) by using standardized fragment type, fragment indicator, and fragment counter fields. This universal approach allows the same fragmentation mechanism to handle varying data sizes effectively while maintaining precise reconfiguration capability at the receive end through consistent information structure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Disclosed is a method for transmitting a packet in a multimedia system, the method comprising the steps of: configuring a payload on the basis of a data unit, wherein the data unit is divided from at least one media processing unit for constituting media data; generating a packet including the payload and a payload header; and transmitting the packet to a receiving end, wherein if the payload is configured on the basis of a plurality of fragments in which the data unit is divided, the payload header includes division information related to the fragments included in the payload, and the division information related to the fragments included in the payload comprises: a fragment indicator indicating whether data included in the payload is a first fragment or is a last fragment among the plurality of fragments, or whether the data is the remainder of fragments excluding the first fragment and the last fragment among the plurality of fragments; and a value of a fragment counter indicating the number of packets having a payload including each fragment following the fragments included in the payload of the packet among the plurality of fragments.
