Solution Overview

Problem

Current methods lack the ability to provide an IP-based TV service with the same user experience as terrestrial, satellite, or cable linear channels, integrate a channel guide with open Internet-based native code reception, and support seamless real-time/non-real-time media streaming across various platforms, without requiring traditional tuners or separate apps.

Innovation Solution

A media data processing method and device that generates and transmits media data and service lists over a network, enabling receivers without traditional tuners to discover and acquire Internet-based broadcast services efficiently, manage service versions, and parse and store services selectively, integrating OTT content into a unified TV platform for seamless access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional tuner-based reception methods are used, then reliable broadcast service reception is achieved, but device complexity and cost increase due to required hardware components

Engineering Contradiction:
Improvebroadcast service reception reliabilityVSAvoidreceiver hardware complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/tuner-based reception systems with software-based IP protocol processing. The receiver uses standard network interfaces and software modules to handle broadcast service reception, eliminating the need for specialized tuner hardware while maintaining reception reliability through protocol stack implementation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent enables a single receiver device to handle multiple reception modes (terrestrial, satellite, cable, and Internet-based broadcast services) through a unified software architecture. The same receiver can process different broadcast protocols and service types without requiring separate dedicated hardware for each reception method.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If separate applications are used for each broadcast service, then service functionality is maintained, but user convenience and system complexity deteriorate due to multiple apps required

Engineering Contradiction:
Improveservice functionality coverageVSAvoiduser operation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges multiple broadcast service applications into a single integrated application that can handle terrestrial, satellite, cable, and Internet-based broadcast services. The unified application provides a common user interface and service management system, eliminating the need for users to install and switch between multiple separate applications.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal broadcast service application that performs multiple functions - receiving different broadcast protocols, managing service lists, handling EPG information, and providing user interfaces for various service types all within a single software package.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If complete service lists are transmitted to all receivers, then service information completeness is ensured, but network bandwidth consumption and transmission time increase

Engineering Contradiction:
Improveservice information completenessVSAvoidnetwork bandwidth consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent implements differential service list updates where only the specific portions of service information that have changed are transmitted to receivers. Each receiver maintains a local cache of service lists and receives incremental updates containing only modified entries, rather than complete service lists, thereby reducing network bandwidth consumption while maintaining information completeness.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs service list versioning and change detection mechanisms that identify and transmit only the updated portions of service information. The system preliminarily determines what changes have occurred and prepares targeted update packets, avoiding the transmission of redundant unchanged information.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If IP-based broadcast services are implemented without integrated protocol standards, then service flexibility is improved, but service interoperability and integration capability deteriorate

Engineering Contradiction:
Improveservice implementation flexibilityVSAvoidprotocol integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the broadcast service protocol stack into distinct functional layers - transport layer handling IP packet transmission, service layer managing service list and EPG information, and application layer providing user interface functions. This segmentation allows each layer to be independently implemented and optimized while maintaining overall system interoperability through standardized interface definitions.

Inventive Principle:
Principle #1Segmentation
