Integrated Chip Interface for Alpha Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated chips require additional interface channels to separate and transmit alpha data from user data, leading to increased processing time and complexity in blending high-resolution user images with video images.
Innovation Solution
An integrated chip and method that transmit user data, including graphic and alpha data, through a single interface channel using a video format like YCbCr 4:2:2, allowing for simultaneous transmission and processing of alpha and graphic data without the need for additional separation, thereby reducing processing time and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional interface channels are used to separate and transmit alpha data from user data, then data transmission completeness is improved, but device complexity and processing time increase
Solution Approach 1:
The patent combines alpha data and graphic data into a single user data stream transmitted through one interface channel. The processor generates user data that includes both alpha values and graphic data, eliminating the need for separate transmission channels while maintaining data completeness through integrated packaging and transmission protocols.
Solution Approach 2:
The interface channel is designed to handle multiple data types simultaneously - it can transmit both alpha data and graphic data through the same channel. This multi-functional capability allows a single channel to replace what would traditionally require multiple specialized channels, reducing overall system complexity.
2Reliability
If additional interface channels are used to separate and transmit alpha data from user data, then data transmission completeness is improved, but processing time increases
Solution Approach 1:
The processor performs preliminary packaging of alpha data and graphic data into a unified user data structure before transmission. This pre-processing ensures that both data types are properly formatted and organized in advance, eliminating the need for sequential separation and transmission operations that would increase processing time.
Solution Approach 2:
By merging alpha data and graphic data into a single transmission stream, the system eliminates the time required for separate transmission operations. The combined data stream is transmitted in one operation rather than requiring multiple sequential transmissions, directly reducing total processing time while maintaining data completeness.
3Manufacturing precision
If separate transmission of alpha data and graphic data is implemented, then data processing accuracy is improved, but productivity decreases
Solution Approach 1:
While transmitting data through a single channel, the patent segments user data into distinct components (alpha data and graphic data) within the data stream. This internal segmentation allows the receiving device to accurately process and separate the data types while maintaining high transmission efficiency through unified channel usage.
Solution Approach 2:
The patent merges alpha data and graphic data into a single transmission channel while preserving their individual structural integrity. This approach maintains data processing accuracy through proper data formatting and delimitation while significantly improving productivity by eliminating the need for multiple transmission channels and operations.

AI summary
An integrated chip communicating with another integrated chip includes a processor configured to generate user data including graphic data representing color space values of each of a plurality of pixels implementing a user image, and alpha data representing an alpha value that specifies how to blend video data and the graphic data and set a video format for transmitting the user data, and a first interface configured to transfer the user data in the video format to the other integrated chip.
