IP Conversion Module for TV Signal Reformatting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receivers, such as digital televisions, lack the capability to properly receive signals formatted using the Internet Protocol, leading to complexities in inventory management and increased costs when all receivers need to be equipped with an Internet Protocol reformatting module, or when only specific receivers intended for Internet Protocol-based networks are equipped with it.
Innovation Solution
An interface module with an input, processor, and output that receives Internet Protocol formatted signals, strips the protocol formatting, and reformatting the signals into an MPEG transport stream, which is then modulated onto an RF channel for compatibility with receivers, ensuring backwards compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all receivers are equipped with an Internet Protocol reformatting module, then receivers can receive Internet Protocol formatted signals, but the cost of every receiver increases and inventory management becomes less complicated only at the expense of higher per-unit costs
Solution Approach 1:
The system is divided into two parts: a standalone Internet Protocol conversion module and a standard receiver. The conversion module handles Internet Protocol signal conversion externally, while the receiver maintains its original simple architecture. This segmentation allows receivers to gain Internet Protocol compatibility without incorporating the conversion capability directly into the receiver hardware, thus avoiding increased per-unit receiver costs.
Solution Approach 2:
An Internet Protocol conversion module serves as an intermediary device between the Internet Protocol network and the standard receiver. This intermediary converts Internet Protocol formatted signals into standard formats that the receiver can process, enabling compatibility without modifying the receiver itself. The intermediary handles the complexity of protocol conversion separately, maintaining the receiver's cost-effectiveness.
2Ease of manufacture
If only specific receivers intended for Internet Protocol-based networks are equipped with an Internet Protocol reformatting module, then cost is reduced for standard receivers, but inventory management becomes more complicated requiring control of two types of receiver
Solution Approach 1:
The standalone Internet Protocol conversion module is designed to be universally compatible with standard receivers through a common interface. This universal module can be used with any standard receiver that needs Internet Protocol compatibility, eliminating the need to manufacture different types of receivers. The module's multi-functionality allows it to serve various receiver models, simplifying inventory management to a single type of conversion module.
3Adaptability or versatility
If an Internet Protocol reformatting module is incorporated in receivers, then Internet Protocol formatted signals can be received, but the complexity of the receiver increases
Solution Approach 1:
The Internet Protocol reformatting functionality is extracted from the receiver and placed in a separate standalone conversion module. This extraction removes the complexity of protocol conversion from the receiver's internal architecture, allowing the receiver to remain simple while still gaining Internet Protocol compatibility through the external module.
Solution Approach 2:
The conversion module acts as an intermediary that handles all Internet Protocol conversion operations externally. This intermediary absorbs the complexity of protocol interpretation and signal reformatting, preventing this complexity from being incorporated into the receiver's design. The receiver interacts with the intermediary through a simple standard interface, maintaining its architectural simplicity.
Data Source
AI summary
An interface module for use between a signal source and a receiver has an input, a processor, and an output. The input receives a signal from the signal source. The received signal contains MPEG files formatted according to an Internet Protocol. The processor strips the Internet Protocol formatting from the received signal and reformats the received signal as a receiver signal containing an MPEG transport stream. The output makes the reformatted signal available for supply to a port supported on a chassis of the receiver.
