Solution Overview

Problem

User equipment often receives unsupported data streams from streaming servers, which cannot be reproduced due to differences in protocols, leading to compatibility issues.

Innovation Solution

The user equipment includes a converting unit that segments and converts the received data stream from one protocol to another, releasing security settings and generating new stream files based on the second protocol, allowing seamless playback of multimedia content across multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If user equipment receives data streams from streaming servers, then content delivery is enabled, but compatibility issues arise when the data stream format is unsupported

Engineering Contradiction:

Improvedata stream format compatibilityVSAvoidcontent reproduction reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a converting unit as an intermediary component between the stream receiving unit and the reproducing unit. This converting unit receives data streams in various formats and converts them to a standard format that the reproducing unit can handle, thereby enabling compatibility with different streaming server formats while ensuring reliable content reproduction.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The converting unit changes the format parameters of the received data stream to match the required playback format. By modifying parameters such as encoding format, resolution, or container type, the system adapts incompatible streams into a reproducible state without changing the core content.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the streaming server transmits data streams in various formats, then service versatility is improved, but user equipment cannot reproduce unsupported formats

Engineering Contradiction:

Improvestreaming format varietyVSAvoidcontent playback ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The user equipment performs self-service by automatically detecting the format of incoming data streams and initiating conversion through the converting unit. The system autonomously handles format incompatibility without requiring user intervention or server retransmission, maintaining ease of operation while supporting format variety.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The converting unit acts as a mediator that transparently handles format conversion. The user interacts with the system as if playing any format directly, while the converting unit mediates between the diverse incoming formats and the reproducing unit's requirements, preserving operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If user equipment converts unsupported data streams to supported formats, then content compatibility is improved, but additional processing complexity is introduced

Engineering Contradiction:

Improvedata stream format supportVSAvoidstream conversion complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The converting unit is segmented into multiple functional modules: a format detection module that identifies incoming stream formats, a conversion module that performs the actual format transformation, and a quality adjustment module that optimizes the converted stream for playback. This segmentation manages complexity by dividing the conversion task into specialized, manageable components.

Inventive Principle:

Principle #1Segmentation

4Loss of energy

If the converting unit converts data streams locally, then server retransmission is avoided, but user equipment processing load increases

Engineering Contradiction:

Improvenetwork energy consumptionVSAvoiduser equipment processing energy

Core Design Contradiction:

Loss of energyVSUse of energy by moving object

Solution Approach 1:

Instead of requesting the server to retransmit the stream in the correct format (which would consume network energy), the system makes a local copy of the received stream and performs format conversion on this copy. This approach trades local processing energy for network energy savings, particularly beneficial when network bandwidth is expensive or limited.

Inventive Principle:

Principle #26Copying

AI summary

Described embodiments provide user equipment for converting a first type data stream to a second type data stream. The user equipment may include a request message transmitting unit, a first stream receiving unit, a converting unit, and a reproducing unit. The request message transmitting unit may transmit a content request message to a streaming server in order to request a predetermined content stored in the streaming server. The first stream receiving unit may receive, from the streaming server, a first type data stream created from the requested content based on a first protocol in response to the content request message. The converting unit may convert the received first type data stream to a second type data stream. The second type data stream may be a data stream generated based on a second protocol. The reproducing unit may reproduce the requested content based on the second type data stream.
