TV Multi-Screen Cloud Processing via Signal Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TV systems require significant resources and data transmission to display multiple channels simultaneously, as they need to receive and process video and audio signals from multiple channels to achieve multi-screen functionality, leading to increased data load and resource utilization.
Innovation Solution
A TV system that transmits a multi-screen request signal to a cloud server, allowing it to configure and display multiple programs from different channels on a single screen using dynamic channel allocation, reducing the amount of data transmitted and optimizing resource usage by dividing the screen into configurable areas with adjustable sizes and audio outputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a TV receives and processes video and audio signals from multiple channels to display multi-screen, then multi-screen display functionality is achieved, but the amount of data transmitted and resources consumed increase significantly
Solution Approach 1:
The patent extracts only the necessary video signal processing from the TV and relocates it to the cloud server. The TV receives a single channel's video signal and requests multi-screen content from the cloud server, which then provides only the necessary additional channel data. This extraction of processing functions reduces the data transmission amount while maintaining multi-screen display functionality.
Solution Approach 2:
The cloud server acts as an intermediary between the TV and multiple broadcast channels. Instead of the TV directly receiving and processing multiple channels, the cloud server mediates by receiving signals from multiple channels, processing them, and selectively transmitting only the necessary data to the TV for multi-screen display.
2Adaptability or versatility
If a TV receives and processes video and audio signals from multiple channels to display multi-screen, then multi-screen display functionality is achieved, but the processing resources required increase significantly
Solution Approach 1:
The patent extracts heavy video signal processing tasks from the TV's limited processing capabilities and relocates them to the cloud server. The TV only performs lightweight tasks such as receiving a base video signal and displaying it, while the cloud server handles the complex processing of multiple channels and generation of multi-screen content, thereby reducing the processing resources required at the TV end.
Solution Approach 2:
The cloud server serves as a powerful intermediary that performs computationally intensive video processing operations. It receives signals from multiple channels, processes them through sophisticated algorithms, and delivers pre-processed multi-screen content to the TV, significantly reducing the processing burden on the TV's hardware resources.
3Adaptability or versatility
If a TV receives all plurality of channels to process multi-screen, then multi-screen display is enabled, but the data transmission amount between server and TV increases
Solution Approach 1:
Instead of requiring the TV to receive all available channels (excessive action), the patent implements partial action by having the TV receive only a single base channel signal and requesting only the necessary additional channel data from the cloud server when multi-screen mode is activated. This partial approach significantly reduces the data transmission amount while still enabling multi-screen display capability.
Solution Approach 2:
The patent extracts the function of channel data selection and processing from the TV and places it in the cloud server. The TV receives minimal data (one channel signal) and the cloud server extracts and provides only the necessary additional channel information needed for the desired multi-screen configuration, thereby minimizing data transmission compared to receiving all channels.
