Solution Overview

Problem

Conventional adaptive streaming technologies for video distribution systems face challenges in managing network load and processing load, particularly as the number of connected cameras increases, leading to potential degradation in video quality.

Innovation Solution

A transmission device that divides video data into first and second data, transmitting the first data to a server for distribution and storing the second data locally. Upon request, the second data is transmitted to the server for distribution to a reception device, thereby optimizing network and processing loads without compromising video quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all transmission data is transmitted to the server device, then video quality is maintained, but network load and processing load increase

Engineering Contradiction:

Improvevideo qualityVSAvoidnetwork load

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The transmission data is divided into two categories: data to be transmitted to the server device and data to be stored in the storage unit. This segmentation allows the system to selectively transmit only essential data, reducing network load while maintaining video quality through the combination of transmitted and stored data.

Inventive Principle:

Principle #1Segmentation

2Reliability

If all transmission data is transmitted to the server device, then video quality is maintained, but processing load on the server increases

Engineering Contradiction:

Improvevideo qualityVSAvoidprocessing load

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The transmission data is segmented into transmitted data and stored data. By storing a portion of the data locally in the storage unit and only transmitting essential data to the server, the processing load on the server is reduced while video quality is maintained through the combination of both data sources.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transmission device performs self-service by storing a portion of the transmission data in its own storage unit, reducing the burden on the server device for data storage and processing. The stored data can be retrieved and combined with transmitted data to maintain video quality without increasing server processing load.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the number of connected cameras increases, then system coverage is improved, but network load and processing load increase

Engineering Contradiction:

Improvesystem coverageVSAvoidnetwork load

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Each camera system segments its transmission data into transmitted and stored portions. This allows multiple cameras to be connected and their data combined without proportionally increasing network load, as each camera only transmits essential data while storing supplementary data locally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of transmitting all camera data through the network, the system performs partial transmission of only essential data, with the remainder stored locally. This reduces the cumulative network load as cameras are added to the system while maintaining comprehensive coverage.

Inventive Principle:

Principle #16Partial or excessive action

4Adaptability or versatility

If the number of connected cameras increases, then system coverage is improved, but processing load on the server increases

Engineering Contradiction:

Improvesystem coverageVSAvoidprocessing load

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments camera data into transmitted and stored portions, allowing multiple cameras to be integrated without proportionally increasing server processing load. The server only processes the transmitted essential data from each camera, while stored data remains locally managed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each camera system provides self-service by managing and storing a portion of its own data locally, reducing the processing burden on the server as more cameras are added to the system. This enables scalable system coverage without linearly increasing server processing requirements.

Inventive Principle:

Principle #25Self-service

AI summary

A transmission device according to an embodiment includes one or more processors. The processors divide a plurality of pieces of transmission data to be transmitted into first data and second data. The processors transmit the first data to a server device configured to distribute the transmission data to a reception device. The processors store the second data in storage. The processors receive, from the reception device or the server device, a request for transmission of the second data. The processors transmit the second data to the server device in accordance with the request for transmission.
