Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current solutions for accessing and sharing multimedia content from broadcast streams, particularly on SetTop Boxes, are complex, error-prone, and poorly suited for acquiring short extracts, requiring manual interaction and lacking ergonomic interfaces for easy sharing.

Innovation Solution

A method for acquiring multimedia stream extracts on a user terminal involves sending requests to a display device and content server, automating the stream identifier acquisition and allowing for quick, ergonomic extraction and sharing of short clips without defining duration, facilitated by a dedicated application and wireless access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual programming of recording on SetTop Box is used, then recording function is available, but operation complexity increases and user ease of operation deteriorates

Engineering Contradiction:

Improverecording functionVSAvoidprogramming complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically detects the multimedia stream being displayed and retrieves it without requiring manual programming. The user simply triggers the request on their terminal, and the system handles stream identification, server communication, and extract retrieval automatically, eliminating the need for complex recording programming.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The user terminal acts as an intermediary between the user and the SetTop Box/recording system. The terminal's application handles the complex interactions with the content server and stream identification, providing a simplified interface to the user while maintaining full recording functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual search and export of content is used, then content access is possible, but time consumption increases and productivity deteriorates

Engineering Contradiction:

Improvecontent accessVSAvoidcontent retrieval speed

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by automatically identifying the current multimedia stream and pre-establishing connections with the content server. When the user triggers the extract request, the system already has the stream identifier and can immediately retrieve the content without manual search or navigation through stored content lists.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The manual mechanical process of searching through content lists and exporting files is replaced by an automated electronic system that uses stream identifiers and server APIs to directly retrieve and transfer the desired extract, dramatically reducing the time required for content access.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If recording of full content is used, then complete content is available, but storage requirements increase and device complexity worsens

Engineering Contradiction:

Improvecontent storageVSAvoidstorage memory

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

Instead of recording or storing complete multimedia content, the system extracts only the specific short segments (extracts) that the user needs. This extraction approach provides full content access capability while using minimal storage space, as only brief extracts are retained rather than entire programs or content.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If complex programming interface is used, then full control is available, but ease of operation deteriorates and user accessibility worsens

Engineering Contradiction:

Improvecontrol functionalityVSAvoiduser interface ergonomics

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The complex control functionality is segmented into two parts: a simple user interface on the terminal that requires only a trigger action, and a sophisticated backend system that handles stream identification, server communication, and extract retrieval. This segmentation provides full control capability while maintaining extreme simplicity for the end user.

Inventive Principle:

Principle #1Segmentation

AI summary

The invention relates to a method for acquiring an extract of a multimedia stream being broadcast on a user's display device, the method being implemented in an user terminal separate from the display device and comprising the following steps: upon reception (207) of a user input for receiving an extract of the multimedia stream being broadcast on the display device, sending (208) to the display device a first request for an identifier of the multimedia stream being broadcast; upon reception (210) of the identifier of the multimedia stream being broadcast, sending (212) to the content server a second request for receiving the multimedia stream extract, said second request including a timestamp of the user input, the identifier of the multimedia stream being broadcast and a duration of the multimedia stream extract; and receiving (214) from the content server the multimedia stream extract or a link to obtain the latter.
