3D Image Data Transmission Using Audio Stream Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D image transmission systems face challenges in efficiently transmitting parallax information and superimposition data, such as OSD displays, which can result in discrepancies in the perceived perspective when displayed on conventional 2D devices, as they lack the necessary depth cues.
Innovation Solution
The proposed system uses the audio compression data stream as a container to transmit parallax information and superimposition data, allowing these elements to be accurately aligned with the left and right eye images, ensuring proper depth perception by shifting the superimposition information based on the parallax vectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parallax information and superimposition data are transmitted using separate channels or protocols, then the transmission reliability is improved, but the system complexity increases
Solution Approach 1:
The patent combines parallax information and superimposition data into a single audio compression data stream container. This merging approach transmits multiple types of data through one unified channel rather than requiring separate transmission protocols, thereby reducing system complexity while maintaining transmission reliability through integrated error handling and synchronization mechanisms
2Device complexity
If the audio compression data stream is used as a container for additional data, then the device complexity is reduced, but the loss of information may increase
Solution Approach 1:
The patent segments the audio compression data stream into distinct portions, allocating specific bits or time slots for parallax information and superimposition data while preserving the original audio data integrity. This segmentation ensures that critical spatial information is extracted and transmitted without being lost in the compression process, maintaining information fidelity while utilizing the audio stream as an efficient container

AI summary
A transmission apparatus includes a first data stream generation unit, a second data stream generation unit, and a data transmission unit. The first data stream generation unit generates an image compression data stream. The second data stream generation unit generates a audio compression data stream to which specific information which is not directly related to audio data is added. The data transmission unit multiplexes the image compression data stream generated by the first data stream generation unit and the audio compression data stream generated by the second data stream generation unit, and transmits the resulting data stream.
