Solution Overview

Problem

In digital broadcasting systems, users face a burden when trying to view or record multi-channel broadcasts as they need to manually select and search for associated content across multiple channels, discouraging multi-channel viewing due to the lack of efficient channel management.

Innovation Solution

A method and receiver that utilize PSIP information to identify and process multiple channels with associated broadcasting content, allowing for simultaneous display and recording of relevant channels by parsing relevant program fields in PSIP tables, enabling automatic joint management of multi-channel broadcasts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually select and search for associated content on multiple channels, then they can view multi-channel broadcasts, but the operation becomes complex and time-consuming

Engineering Contradiction:

Improveease of multi-channel viewingVSAvoidtime for channel selection and search

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically detecting and bundling associated channels before user viewing. The receiver proactively identifies channels with associated broadcasting content through PSIP information parsing and prepares them for joint management, eliminating the need for users to manually search and select each channel individually.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically managing multi-channel associations without requiring user intervention. The receiver autonomously detects associated channels, bundles them according to broadcasting content relevance, and provides joint management capabilities, allowing the system to serve itself in identifying and organizing multi-channel content.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If users manually select each channel separately, then they can access associated content, but the device complexity increases

Engineering Contradiction:

Improveaccess to associated contentVSAvoidcomplexity of channel management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system merges the management of multiple associated channels into a unified process. By bundling channels with associated broadcasting content and implementing joint management, the receiver combines what would otherwise require separate manual selection and configuration into a single automated operation, reducing the perceived complexity for users.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system implements multi-functionality by enabling the receiver to simultaneously manage viewing, recording, and editing across multiple associated channels through a single unified interface. The joint management mechanism allows one operation to affect multiple channels universally, rather than requiring separate control for each channel.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the receiver processes each multi-channel separately, then channel independence is maintained, but user convenience decreases

Engineering Contradiction:

Improvechannel processing independenceVSAvoiduser convenience for multi-channel viewing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system merges the processing of multiple associated channels while maintaining their individual identities. By bundling channels based on associated broadcasting content and implementing joint management, the receiver combines separate processing operations into unified actions that affect multiple channels simultaneously, improving user convenience without compromising channel independence.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method of controlling a receiver for processing a broadcast signal defining a multi-channel broadcast, and a broadcast receiver using the same, enable the joint management of a plurality of channels, which are effectively bundled together according to relevance of broadcasting Content, such that broadcast programs of associated channels can be simultaneously processed, including processes of viewing, recording, and editing. The method includes steps of receiving a broadcast signal having additional information, the additional information including associated channel Information indicating a channel of associated broadcasting content, the associated channel information enabling the receiver to recognize channels having associated broadcasting content; detecting, based on the associated channel information, at least one channel having the associated broadcasting content according to a selection of a specific channel, the detected at least one associated broadcasting content channel having broadcasting content associated with the selected channel; and processing in tandem a broadcast program of the selected channel and a broadcast program of the detected at least one channel.
