Solution Overview

Problem

Conventional display technologies face limitations in efficiently formatting and delivering mixed two and three-dimensional video data, particularly in supporting simultaneous display of different video content configurations and perspectives, which can exceed bandwidth limitations and require specialized glasses for 3D viewing.

Innovation Solution

The development of frame formatting techniques that allow for the simultaneous display of mixed two and three-dimensional video data by encoding frames to indicate specific screen configurations and regions, enabling adaptable display devices to render appropriate content without the need for special glasses, using parallax barriers or lenticular lenses to create depth perception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional frame formats are used for 3D video communication, then rigid structure and standardized interpretation are achieved, but flexibility in supporting mixed 2D and 3D content and multiple perspectives is lost

Engineering Contradiction:
Improveflexibility in supporting mixed 2D and 3D contentVSAvoidframe format structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame format is segmented into distinct regions (first screen region for 2D content, second screen region for 3D content) with dedicated field content for each. This segmentation allows independent handling of different content types within a single frame structure, providing flexibility while maintaining standardized interpretation of each region.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame format structure is designed to be universal by supporting multiple content types (2D video, 3D video with different perspectives) within the same standardized framework. The format can adapt to display various configurations including single-view 3D, multi-view 3D, and mixed 2D/3D content without requiring separate standardized formats.

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

2Adaptability or versatility

If multiple full-screen frame sequences are transmitted for different perspectives, then complete 3D viewing experience is provided, but bandwidth consumption increases significantly

Engineering Contradiction:
Improvesupport for multiple perspectivesVSAvoidbandwidth consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Different regions of the screen are assigned different qualities and purposes: the first screen region displays 2D content while the second screen region displays 3D content from multiple perspectives. This local differentiation allows efficient use of bandwidth by transmitting only the necessary perspective data for each region rather than full-frame sequences for all perspectives.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent transitions from transmitting multiple full-screen frame sequences (temporal dimension) to transmitting multiple perspectives within a single frame structure (spatial dimension). This dimensional change in data organization allows simultaneous delivery of multiple perspectives with reduced bandwidth consumption.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If specialized glasses are used for 3D viewing, then depth perception is enhanced, but device complexity and viewing requirements increase

Engineering Contradiction:
Improvedepth perception qualityVSAvoidviewing equipment requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The display device itself provides the 3D viewing capability through integrated light manipulators (parallax barriers or lenticular lenses) rather than requiring external specialized glasses. The system serves its own 3D functionality through built-in optical components that work with the multi-perspective frame format to deliver depth perception directly to the viewer.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This approach allows for efficient bandwidth utilization, supports multiple screen configurations, and enables seamless display of two and three-dimensional content on a single device, enhancing viewer experience without the need for specialized viewing equipment.

Implementation Method 1

a display may include a parallax barrier that has a layer of material with a series of precision slits. The parallax barrier is placed proximal to a display so that a user's eyes each see a different set of pixels to create a sense of depth through parallax.

Methodology Applied
Scientific EffectParallax: Parallax

Implementation Method 2

Another type of display for viewing three-dimensional images is one that includes a lenticular lens. A lenticular lens includes an array of magnifying lenses configured so that when viewed from slightly different angles, different images are magnified.

Methodology Applied
Scientific EffectLens magnification and refraction: Lens

AI summary

Systems and methods are provided that relate to frame formatting supporting mixed two and three dimensional video data communication. For example, frames in frame sequence(s) may be formatted to indicate that a first screen configuration is to be used for displaying first video content, that a second screen configuration is to be used for displaying second video content, and so on. The screen configurations may be different or the same. In another example, the frames in the frame sequence(s) may be formatted to indicate that the first video content is to be displayed at a first region of a screen, that the second video content is to be displayed at a second region of the screen, and so on. The regions of the screen may partially overlap, fully overlap, not overlap, be configured such that one or more regions are within one or more other regions, etc.
