Video Signal Transmission Embedding Configuration Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transmitting video signals between image processors face challenges in ensuring synchronization, leading to potential split displays and non-uniform pictures due to separate data channels for video and configuration information, which are costly and difficult to manage.
Innovation Solution
Embedding configuration data in the previous invalid intervals of video signal frames and transmitting them through a single data channel, ensuring the configuration data reaches the receiving end before the associated frame data, allowing for synchronized processing and avoiding split displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data transmission channels are used for video signal and configuration information, then the transmission of both signals can be achieved, but the hardware cost increases and synchronization becomes difficult to ensure
Solution Approach 1:
The patent merges the transmission of video signals and configuration information into a single data transmission channel. Configuration information is embedded within the video signal transmission channel, eliminating the need for separate channels and reducing hardware complexity while maintaining reliable synchronization between video data and configuration parameters.
Solution Approach 2:
The patent applies preliminary action by transmitting configuration information in advance within the same data channel as the video signal. The configuration data is embedded and transmitted before the corresponding video frame data, ensuring that the receiving end has the necessary configuration parameters ready before processing the video data, thus achieving synchronization without requiring separate channels.
2Reliability
If configuration information is transmitted separately, then it can reach the receiving end, but it may arrive during video frame transmission causing split display and non-uniform pictures
Solution Approach 1:
The patent ensures configuration information is delivered in advance by embedding it in the video signal stream before the corresponding frame data. The receiving end extracts and processes configuration parameters before they are needed for video frame processing, preventing split displays and ensuring uniform picture quality throughout the transmission process.
3Device complexity
If a single data transmission channel is used, then hardware cost is reduced, but ensuring synchronization between video signal and configuration data becomes challenging
Solution Approach 1:
By transmitting configuration information in advance within the same data channel, the patent ensures that the receiving end has configuration parameters ready before video frame processing begins. This preliminary delivery mechanism maintains synchronization reliability while using a single transmission channel, eliminating the need for complex multi-channel synchronization protocols.
