Game Stream Overlay Using Separate Compression for Player Area Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game systems lack flexibility in integrating captured images of players into game environments, leading to inefficient processing and potential quality loss in superimposing player images onto game images.
Innovation Solution
An information processing system that distributes first data (game image data) and second data (captured image data with area data) separately, using different compression methods to maintain image quality and reduce data loss, allowing for efficient superimposition of player images onto game environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If captured image data and area data are compressed using the same compression method, then processing is simplified, but image quality deteriorates due to inappropriate compression for each data type
Solution Approach 1:
The patent divides the compression processing into separate paths for captured image data and area data. Captured image data is compressed using a first compression method suitable for image content, while area data is compressed using a second compression method optimized for spatial/coordinate information. This segmentation allows each data type to be processed with the most appropriate algorithm, preventing quality degradation while maintaining processing efficiency.
2Quantity of substance
If lossy compression is used for captured image data, then data amount is reduced, but image quality deteriorates
Solution Approach 1:
The patent applies different compression parameters and methods tailored to each data type. For captured image data, lossy compression parameters are optimized to preserve visual quality while reducing data size. For area data, lossless compression parameters are used to maintain precise spatial information. This parameter optimization allows significant data reduction without compromising the quality of each respective data type.
3Quantity of substance
If area data is compressed with high compression ratio, then data amount is reduced, but positioning precision deteriorates due to data loss
Solution Approach 1:
The patent recognizes that area data, while important for positioning, can be efficiently compressed using lossless methods that preserve all essential information. The system accepts the overhead of slightly larger data size for area data compared to lossy compression, but gains precise positioning accuracy. This trade-off is managed by using appropriate compression schemes that maintain the integrity of spatial coordinates.
4Adaptability or versatility
If image data and area data are distributed separately, then processing flexibility is improved, but system complexity increases
Solution Approach 1:
The patent combines the distribution of image data and area data into a unified transmission framework where both data types are sent together from the distribution terminal to the reception terminal. This merging approach maintains the processing flexibility of separate handling while simplifying the overall system architecture by using a single distribution channel, thereby reducing system complexity.

AI summary
An information processing system includes a distribution terminal configured to distribute first data and second data, the first data including image data of a game being executed, the second data including captured image data obtained from a camera and area data indicating an area of a person included in the captured image data, and a reception terminal configured to receive the first data and the second data from the distribution terminal and generate based on the area data, a distributed display image in which the area of the person in the captured image data is shown superimposed on an image of the game being executed in the distribution terminal.
