Television Signal Processing Segmentation for Network Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current television apparatuses face inefficiencies and high costs when adding new applications, as they require redesigning both hardware and software to accommodate increasing content providers, leading to a heavy load on internal control programs and inefficient processing.
Innovation Solution
A television apparatus is configured with a first block for receiving television signals and a second block connected to a network, featuring a bypass route for image signals, a processor for generating return streams, and a converter for outputting display signals, allowing for software development with minimal hardware changes by separating signal processing and network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new applications are added to accommodate increasing content providers, then the functionality and adaptability of the television apparatus is improved, but the hardware and software must be redesigned, increasing device complexity and development costs
Solution Approach 1:
The television apparatus is divided into two independent blocks: a first block for receiving television signals and a second block for network connectivity. This segmentation allows each block to operate independently, enabling new applications to be added to the second block without redesigning the entire system, thus improving adaptability while maintaining manageable complexity
Solution Approach 2:
The first block is designed with a converter that can process both television signals from the receiving block and return streams from the second block. This universal processing capability allows the same hardware to serve multiple functions, accommodating different content providers without requiring separate processing paths for each application
2Adaptability or versatility
If the television apparatus processes data from multiple different signal sources, then the versatility is improved, but the internal control program bears a heavy load, increasing processing complexity
Solution Approach 1:
By separating the television signal processing (first block) from network data processing (second block), each block has its own dedicated processing path. The bypass route allows television signals to pass through without requiring the control program to manage both signal types simultaneously, reducing the processing load while maintaining the ability to handle multiple signal sources
Solution Approach 2:
The converter acts as an intermediary that receives both television signals from the receiving block and return streams from the second block, converting them into a unified format for display. This intermediary approach simplifies the control program's task by providing a single point of convergence for different signal sources, reducing processing complexity
3Adaptability or versatility
If independent blocks are used for computer data processing and DVD reproducing signal processing, then the adaptability to different signal sources is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of creating separate independent blocks for each signal source, the patent merges the network processing capability into a second block that interfaces with the existing first block through a standardized converter. This consolidation reduces the number of independent blocks needed while maintaining the ability to process multiple signal types, thereby reducing device complexity and cost

AI summary
According to one embodiment, the apparatus has a first block configured to be connected to a receiving block for a television signal and a second block independent from the first block, configured to be connected to a network. A bypass route is configured to lead a bypass stream including an image signal from the first block to the second block. A processor is configured to generate a return stream by inserting the image signal from the network into the image signal on the bypass stream, at the second block. A return pass is configured to return the return stream to the first block. And a converter is configured to convert the image signal included in the return stream into a signal for output and display, at the first block.
