MHP Terminal Device Local Network Interface Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing MHP terminal devices are limited to receiving MHP applications only through broadcast streams, lacking the ability to integrate local network functionality, which restricts user interaction and control over network devices connected to the local network.
Innovation Solution
Incorporating a local network interface into the MHP terminal device to receive and exchange MHP applications and data streams from other network devices, enabling remote control and access of network devices via a graphical user interface, while using a resident application to manage both broadcast and local network applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MHP terminal devices use only broadcast interface to receive MHP applications, then the device architecture remains simple and standardized, but the device cannot access or control local network devices
Solution Approach 1:
The MHP terminal device is enhanced with a local network interface that enables it to perform multiple functions: receiving MHP applications from both broadcast and local network sources, exchanging data streams with network devices, and providing remote control capabilities. This multi-functionality allows a single device to operate in both traditional broadcast environments and modern networked environments without requiring separate specialized equipment.
Solution Approach 2:
The system architecture is segmented into independent functional modules: the broadcast interface continues to handle traditional broadcast MHP applications, while the newly added local network interface handles network-based MHP applications and device control. This segmentation allows each interface to operate independently with its own protocol stack, maintaining backward compatibility while adding new capabilities without interfering with existing functionality.
2Ease of operation
If MHP applications are distributed only through broadcast streams, then the distribution mechanism remains simple and centralized, but users cannot exchange applications or control signals between local network devices
Solution Approach 1:
The local network interface acts as an intermediary between the MHP terminal device and other network devices. It enables bidirectional communication for exchanging MHP applications, data streams, and control signals. The interface mediates the interaction by providing standardized protocols for application distribution and device control, making complex network communications transparent to the user through a unified graphical interface.
3Adaptability or versatility
If the MHP terminal device lacks local network interface, then the device structure remains simple and cost-effective, but it cannot provide remote control functionality for network devices
Solution Approach 1:
The remote control functionality is merged into the MHP terminal device by integrating the local network interface with the existing MHP application framework. The same graphical user interface and application execution environment that handle broadcast MHP applications are extended to also handle network device control. This merging allows users to control network devices through familiar MHP application interfaces without adding separate complex control systems.

AI summary
A MHP terminal device is provided with a network functionality. In addition to a broadcast interface for receiving a broadcast transport stream, the MHP terminal device comprises a local network interface. Via said interface, the MHP terminal device is connected to a local network, to which other network devices are connected as well. MHP applications can be inserted into local network transport streams transmitted from said network devices to said MHP terminal device. By means of these MHP applications, the network devices can be remotely controlled from the MHP terminal device, whereby commands and messages are exchanged via the local network.
