Digital Receiver EPG Service System with Server-Side Data Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital receivers face limitations in providing comprehensive Electronic Program Guides (EPGs) with sufficient channel or service coverage and metadata, leading to inadequate user experience and service quality due to restricted EPG data from broadcasting stations.
Innovation Solution
A method and system that collect and process EPG data from multiple digital receivers and an external EPG server, using a server to manage and combine data, providing enhanced EPG services with improved metadata and channel coverage, and utilizing a cloud server system for efficient image management and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If EPG data is collected only from broadcasting stations, then the system is simple, but the channel coverage and metadata completeness are insufficient
Solution Approach 1:
The patent combines EPG data from multiple sources including broadcasting stations, external EPG servers, and user terminals into a unified service system. This merging of data sources expands channel coverage and metadata completeness without requiring a completely new system architecture.
Solution Approach 2:
The service system is designed to handle multiple data sources and types universally. It can process EPG data from broadcasting stations, external servers, and user terminals through a common data processing framework, making the system adaptable to various input sources.
2Loss of information
If EPG data is collected from multiple sources, then metadata completeness improves, but data management complexity increases
Solution Approach 1:
The patent introduces an EPG data processing server as an intermediary between multiple data sources and user terminals. This mediator collects, validates, processes, and distributes EPG data, simplifying the management complexity by centralizing data handling functions.
Solution Approach 2:
The data management system is segmented into distinct functional modules including data collection, validation, processing, and distribution components. This segmentation allows each module to handle specific tasks independently, reducing overall system complexity while maintaining metadata completeness.
3Ease of operation
If comprehensive EPG data is provided to all users, then user satisfaction improves, but network bandwidth consumption increases
Solution Approach 1:
The patent implements preliminary processing and caching of EPG data at the server side and user terminals. Frequently accessed EPG information is pre-processed and stored locally, reducing the need for repeated network transmissions while maintaining user access to comprehensive data.
Solution Approach 2:
The system allows user terminals to store and access EPG data locally after initial retrieval. This local caching provides comprehensive EPG information to users without requiring continuous network bandwidth consumption, as data is accessed from local storage rather than repeated network requests.
