Solution Overview

Problem

Existing satellite television systems do not allow for seamless transfer and playback of stored content from a home-based DVR to a mobile receiving device, limiting entertainment options for rear passengers in vehicles.

Innovation Solution

A method and system for transferring video and audio files from a satellite receiver's storage device to a portable memory device and then to a mobile playback device, enabling playback on a mobile receiving device while ensuring security through matching household keys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content is stored on a home-based DVR, then content can be recorded and stored for later viewing, but the content cannot be transferred to a mobile device for playback

Engineering Contradiction:

Improvecontent playback capabilityVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the content delivery function into two independent parts: a home-based DVR for content recording and storage, and a mobile receiver for content playback. The content can be transferred from the DVR to the mobile receiver via portable memory devices, allowing content to be consumed in different locations without requiring a single integrated system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces portable memory devices as intermediaries between the home-based DVR and the mobile receiver. These memory devices serve as a bridge to transfer content files from the stationary DVR system to the mobile receiving device, enabling content portability without direct wireless communication infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a mobile satellite receiver is provided for vehicle entertainment, then rear passengers can enjoy programming, but the receiver cannot access content stored on the home-based DVR

Engineering Contradiction:

Improvecontent accessibilityVSAvoidcontent transfer time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system allows content to be pre-transferred from the home-based DVR to portable memory devices before travel. This preliminary action enables the mobile receiver to access content immediately upon connection without requiring time-consuming wireless downloads or streaming during the vehicle trip.

Inventive Principle:

Principle #10Preliminary action

3Speed

If direct wireless transfer between DVR and mobile device is implemented, then content can be transferred quickly, but security and authentication become more complex

Engineering Contradiction:

Improvecontent transfer speedVSAvoidauthentication system

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent uses portable memory devices as intermediate copies between the DVR and mobile receiver. Content is copied to the memory device from the DVR and then copied from the memory device to the mobile receiver. This copying approach through a trusted intermediate medium simplifies security requirements compared to implementing secure direct wireless communication protocols.

Inventive Principle:

Principle #26Copying
