Solution Overview

Problem

Conventional DVD storage media record multi-angle data using an interleaving method, resulting in non-contiguous data storage, which requires frequent position changes during reproduction, leading to time delays and bit rate limitations when reading from optical or hard discs.

Innovation Solution

The solution involves recording multi-angle data in contiguous areas using a non-interleaving method, with each angle's data divided into clips that include jumping points for seamless transitions between angles, and additional information for navigation, allowing for random access and efficient reproduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multi-angle data is recorded using an interleaving method, then data can be stored on the storage medium, but the data is stored in non-contiguous areas requiring frequent position changes during reproduction

Engineering Contradiction:

Improvedata storage capacityVSAvoidtime delay during position changes

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The storage medium is divided into multiple track areas, each dedicated to storing data for a specific angle. This segmentation allows the reproducing apparatus to access all data for one angle contiguously within a single track area, eliminating the need to jump between tracks during angle-specific playback and thus reducing position change time delays.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multi-angle data is recorded using an interleaving method, then data can be stored alternately by angle, but frequent position changes are required during reproduction

Engineering Contradiction:

Improvemulti-angle data organizationVSAvoidreproduction efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent introduces a new organizational dimension by arranging multi-angle data not alternately in the same track (interleaving) but rather in separate track areas. This dimensional change from radial interleaving to angular separation allows the reproducing apparatus to maintain high productivity when playing back a single angle, while still supporting multiple angles through the multi-track structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If position changes are made frequently during reproduction, then all angles can be accessed, but bit rate stability is compromised

Engineering Contradiction:

Improveangle switching capabilityVSAvoidbit rate stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system pre-organizes data by angle into separate track areas and pre-calculates the optimal number of track areas needed based on the maximum bit rate requirements. This preliminary organization ensures that when reproduction begins, the apparatus can access all necessary data contiguously without mid-playback position changes that would disrupt bit rate stability, while still maintaining the capability to switch between angles.

AI summary

An information storage medium on which multi-angle data is recorded includes at least two clips in each of which video object data for an angle of the multi-angle data is recorded. The at least two clips are recorded in contiguous areas of the information storage medium.
