Solution Overview

Problem

Internet video services like BIVL require users to browse and search content on a single device, disrupting the viewing experience and limiting functionality on devices without GUI capabilities, such as home audio or video devices.

Innovation Solution

A system allowing users to subscribe to and manage channels and content across multiple devices, using a second device for browsing while the main device handles playback, with a method that includes selecting subscription channels, modifying user lists, and executing commands on those channels, ensuring seamless content playback without interrupting the main device's viewing experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If content browsing and playback are performed on a single device, then device complexity is reduced, but the viewing experience is disrupted and functionality is limited on devices without GUI capabilities

Engineering Contradiction:
Improveviewing experienceVSAvoidsystem architecture
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system divides the IPTV service functionality into two separate devices: a main device for content playback and a second device for content browsing and subscription management. This segmentation allows each device to specialize in its intended function, improving the viewing experience while maintaining manageable complexity through clear functional separation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second device is designed to perform multiple functions including browsing content, managing subscriptions, and controlling playback on the main device. This multi-functionality allows devices without GUI capabilities to access BIVL services through alternative interfaces, expanding system versatility.

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

2Ease of operation

If a second device is used for browsing content, then the viewing experience is improved, but security risks increase due to unauthenticated access

Engineering Contradiction:
Improvecontent browsingVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system introduces an intermediary authentication mechanism where the second device does not directly access proprietary content URLs. Instead, it communicates playback commands to the main device, which holds the authenticated credentials. This intermediary role of the main device maintains security while enabling convenient browsing on the second device.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If devices without GUI capabilities are used, then hardware requirements are reduced, but the ability to browse BIVL services is lost

Engineering Contradiction:
Improvedevice accessibilityVSAvoidservice accessibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The system creates a virtual representation of the BIVL service interface on the second device through text-based or alternative GUI interfaces. This copying of the browsing functionality in an adapted form allows devices without traditional GUI capabilities to access and navigate BIVL services effectively.

Inventive Principle:
Principle #26Copying
