DVB Mobile TV Streaming With Signal Mediation and Program Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital video broadcast (DVB) systems face challenges in providing stable and high-definition TV viewing on mobile devices due to signal interference and reception issues, particularly in indoor environments, and network-dependent mobile viewing experiences are marred by instability and limited clarity.
Innovation Solution
A data processing method and device that enables a DVB device to connect with mobile terminals, providing a filtered program list for direct viewing and, if needed, accessing additional programs from a server, while ensuring secure authentication through binding user accounts, thus stabilizing the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large satellite antenna is installed to improve signal reception, then signal receiving capability is improved, but device size and installation difficulty increase
Solution Approach 1:
The patent introduces a signal enhancement device as an intermediary component between the satellite signal source and the DVB device. This intermediary device processes and enhances the satellite signal before it reaches the DVB device, allowing the system to achieve reliable signal reception without requiring a large satellite antenna. The signal enhancement device acts as a mediator that bridges the gap between weak indoor satellite signals and the DVB device's reception requirements.
2Ease of operation
If satellite signals are transmitted directly to mobile terminals through the network, then viewing convenience is improved, but picture clarity is limited and viewing fluency fluctuates with network conditions
Solution Approach 1:
The DVB device serves as an intermediary between the satellite signal source and the mobile terminal. Instead of transmitting raw satellite signals directly to mobile terminals through the network, the DVB device receives, processes, and converts the satellite signals into a format suitable for mobile terminal display. This intermediary processing ensures both high picture quality from stable satellite signals and convenient mobile access, resolving the contradiction between viewing convenience and picture clarity.
3Ease of operation
If the DVB device is placed indoors for convenience, then ease of installation is improved, but signal reception becomes unstable
Solution Approach 1:
The signal enhancement device functions as an intermediary that compensates for the weak indoor satellite signals. By placing this enhancement device in the indoor environment with the DVB device, the system maintains the convenience of indoor installation while the enhancement device actively processes and strengthens the satellite signals to ensure stable reception, thus resolving the contradiction between installation convenience and signal stability.
Data Source
AI summary
A data processing method based on DVB, a DVB device, and a readable storage medium are provided. In the data processing method, the DVB device is connected to a mobile terminal, so a user is allowed to watch TV programs on the mobile terminal. When a viewing request is sent, the DVB device analyzes the viewing request and feeds back a first program list. The user may directly select a first program from the first program list. If the user does not find a required program and performs a search operation, the DVB device requests a second program list from a server and matches search information with the second program list, and sends a matching result and the second program list to the mobile terminal. After receiving a second on-demand operation, the DVB device sends the data stream of the second program to the mobile terminal.
