Digital Broadcasting Receiver Interactive Subtitle Port Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile digital broadcasting systems are limited by a lack of bidirectional communication and unidirectional information provision, failing to activate a profitable model for both mobile communication providers and broadcasting stations.
Innovation Solution
A digital broadcasting receiver and data processing method that generates Reed-Solomon frames from received mobile broadcasting signals, extracts electronic service guide data, and checks port numbers for subtitle reference information to enable the display of subtitles with access information, allowing direct interaction with entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If mobile digital broadcasting system uses unidirectional subtitle information provision, then system complexity is reduced, but user interaction capability deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (port number checking and entity resolution system) that bridges the gap between simple subtitle transmission and complex bidirectional interaction. The receiver checks port numbers in SDP data to identify subtitle streams with reference information, then resolves entities using these references, enabling interactive capabilities without requiring complete system redesign.
2Adaptability or versatility
If mobile digital broadcasting system implements bidirectional communication, then user interaction capability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by embedding port number information and entity reference data in advance within the SDP data and subtitle streams. The receiver checks these pre-configured port numbers to identify interactive subtitle streams, and resolves entities using pre-provided reference information, thereby enabling bidirectional communication without requiring complex real-time processing.
3Device complexity
If traditional mobile digital broadcasting system is used, then profit model limitations are avoided, but revenue generation capability deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where users can interact with subtitle content through resolved entities (such as accessing additional information, making purchases, or providing responses). This feedback loop creates new revenue streams by enabling targeted advertising, e-commerce transactions, and value-added services based on broadcast content, transforming the traditionally unidirectional broadcasting model into an interactive revenue-generating system.
Data Source
AI summary
A digital broadcasting system and a data processing method are disclosed. A data processing method of a digital broadcasting receiver comprises receiving a mobile/handheld (MH) broadcasting signal including mobile service data and main service data; generating RS(Reed-Solomon) frames from the received MH broadcasting signal; extracting ESG (electronic service guide) data from the generated RS frame; extracting SDP (session description protocol) data from the extracted ESG data; checking a port number corresponding to subtitle having reference information, among the extracted SDP data; and controlling the subtitle having reference information using the checked port number so that the subtitle having reference information is displayed.
