De-encapsulating Data Streams into Multiple Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices that receive data streams may not be capable of recognizing multiple channel formats, such as 3D video, which are transmitted in a format that includes both a left and right channel, leading to compatibility issues with receivers that can only handle single channel (mono) formats.
Innovation Solution
A method and apparatus that de-encapsulate data streams into multiple sub-streams by stripping and rearranging data frames to transmit each channel separately via different links, using a format conversion chip to transform 3D data streams into mono data sub-streams, allowing non-3D enabled receivers to receive and process the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multi-channel data streams (3D format) are transmitted, then data transmission capacity is improved, but compatibility with single-channel receivers deteriorates
Solution Approach 1:
The patent segments the multi-channel 3D data stream into multiple separate single-channel data sub-streams. Each data sub-stream carries content from one channel (left or right eye) in mono format, allowing single-channel receivers to process each sub-stream independently while maintaining compatibility with existing receiver hardware.
2Manufacturing precision
If data is transmitted in 3D multi-channel format, then image quality is improved, but receiver capability requirements increase
Solution Approach 1:
The patent divides the 3D multi-channel data stream into separate single-channel sub-streams, where each sub-stream contains data for one channel (left or right eye). This segmentation allows standard single-channel receivers to process each sub-stream without requiring advanced 3D processing capabilities, thereby reducing receiver complexity requirements while preserving image quality through proper channel separation.
Solution Approach 2:
The patent introduces a format conversion chip as an intermediary device between the transmitter and receiver. This chip performs the de-encapsulation of multi-channel data into single-channel sub-streams, shielding the receiver from the complexity of 3D format processing while maintaining the benefits of high-quality 3D data transmission.
3Productivity
If multi-channel content data is sent in a single data stream, then transmission efficiency is improved, but receiver recognition capability becomes insufficient
Solution Approach 1:
The patent segments the multi-channel data stream into multiple single-channel data sub-streams that can be independently processed by standard receivers. Each sub-stream is properly formatted with synchronization signals and channel identifiers, making it easily recognizable and processable by single-channel receivers while maintaining the efficiency of structured data transmission.
Solution Approach 2:
The format conversion chip acts as an intermediary that transforms complex multi-channel data streams into simple single-channel sub-streams. This intermediary processing ensures that the data maintains transmission efficiency while becoming easily recognizable and processable by receivers with limited recognition capabilities.

AI summary
Embodiments of the invention are generally directed to de-encapsulation of data streams into multiple links. An embodiment of a method includes receiving a data stream including multiple data frames, the data stream being in a first mode having a multiple channels of content data including a first channel sent in a first position in each data frame and a second channel sent in a second position in each data frame following the first position, with each data frame including a synchronization signal to indicate a start of the content data. The method further includes transforming the data stream into data sub-streams in a second mode, the data sub-streams including a first data sub-stream to carry data for the first channel in the second mode and a second data sub-stream to carry data for the second channel in the second mode. Transforming the data stream into in the plurality of data sub-streams includes generating the first data sub-stream by stripping the second channel from each frame of data, and generating the second data sub-stream by stripping the first channel and the synchronization signal from each frame and inserting a substitute synchronization signal before the second channel data in each data frame. The method further includes transmitting the first data sub-stream via a first link in the second mode and the second data sub-stream via a second link in the second mode.
