Composite Video Stream Merging for Multi-Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing television systems require additional electronics and processing capabilities to display multiple video streams simultaneously, making them expensive and inefficient for users who want to watch multiple related video streams, such as different sporting events, on a single display.
Innovation Solution
The method involves generating a composite video stream from multiple video streams and transmitting it along with associated audio streams on a single carrier frequency, allowing a receiver to display multiple video streams and audio streams on a single display device, including the option to select and render high or low resolution streams based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If picture-in-picture capabilities are provided with additional tuners and processing electronics, then multiple video streams can be displayed simultaneously, but the system becomes expensive and complex
Solution Approach 1:
The patent combines multiple video streams and audio streams into a single composite channel that is transmitted over one carrier frequency. This merging approach allows multiple video streams to be displayed simultaneously on a single display device without requiring multiple separate tuners or complex processing electronics, as the receiver can process the composite channel and separate the individual video and audio streams for display.
2Reliability
If multiple video streams are transmitted on different carrier frequencies, then each stream can be received independently, but the system requires multiple tuners and increases transmission complexity
Solution Approach 1:
The patent merges multiple video streams and their associated audio streams onto a single carrier frequency, creating one composite channel. This allows a receiver with a single tuner to access all video streams simultaneously by processing the composite channel and separating the individual streams, eliminating the need for multiple tuners while maintaining the ability to receive and display each stream independently.
3Manufacturing precision
If high resolution video data is transmitted for all streams, then display quality is maintained, but bandwidth consumption increases and transmission efficiency decreases
Solution Approach 1:
The patent applies different resolution qualities to different video streams within the composite channel based on their importance and display requirements. Critical or primary video streams can maintain high resolution, while secondary or supplementary streams can be transmitted at lower resolutions. This local quality differentiation allows the system to maintain acceptable display quality for important content while reducing overall bandwidth consumption and improving transmission efficiency.

AI summary
The systems and methods disclosed transmit a composite channel to a receiver. The composite channel may be a static channel that contains different original channels of content in different locations on a displayed page, or may be a dynamic channel that is processed by the receiver to display a multiple different video streams on a single display device.
