Solution Overview

Problem

Existing video bitstreams require multiple variations to accommodate different display technologies and ambient conditions, leading to increased storage and network costs due to the need for separate content creation and transmission for opaque and transparent screens.

Innovation Solution

A method for encoding and decoding video bitstreams that includes transparency data, allowing a single bitstream to be used across various display devices by adjusting image data based on intended transparency levels and ambient conditions, reducing the need for multiple content versions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple video bitstream variations are provided for different display technologies, then compatibility with various display devices is improved, but storage and network transmission costs increase

Engineering Contradiction:

Improvecompatibility with various display devicesVSAvoidstorage and transmission data volume

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent merges multiple video bitstream variations into a single bitstream by integrating transparency data as metadata alongside standard image data. This allows one bitstream to contain all necessary information for both opaque and transparent display rendering, eliminating the need for separate bitstream versions and reducing storage and transmission requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal video bitstream format that serves multiple display technologies simultaneously. By embedding transparency data that can be interpreted by both traditional and transparent displays, the same bitstream becomes multi-functional, adapting to different display capabilities without requiring separate content versions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If transparency data is integrated into the video bitstream, then a single bitstream can serve both opaque and transparent displays, but bitstream complexity increases

Engineering Contradiction:

Improvesingle bitstream for multiple display typesVSAvoidbitstream structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the video bitstream into distinct components: standard image data and transparency metadata. This segmentation allows each component to be processed independently according to display capabilities, simplifying the overall structure compared to creating entirely separate bitstreams while maintaining adaptability across different display types.

Inventive Principle:

Principle #1Segmentation

AI summary

Apparatus and method are provided for decoding an encoded video bitstream with multiple frames for displaying a video on a transparent display. The method includes: receiving the encoded video bitstream, in which the video bitstream includes image data including multiple image values representing an image to be displayed and transparency data representing an intended transparency level of at least a part of the image to be displayed. For at least one frame of the video bitstream: the method further includes decoding received encoded image data to obtain a decoded image data; determining whether a current frame includes transparency data; in case the current frame includes transparency data: adjusting the decoded image data to obtain a transparency-adjusted image data depending on received transparency data.
