Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The lack of guidelines for session partitioning rules in DVB-H reception terminals leads to confusion and increased data processing time when receiving Electronic Service Guide (ESG) data in multiple-stream mode, especially as the amount of ESG data increases.

Innovation Solution

A method and DVB-H reception terminal that determine and apply session partitioning rules to each ESG data session, allowing for efficient acquisition and processing of ESG data by detecting the type of rule applied and acquiring data based on those rules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If ESG data is transmitted in multiple-stream mode with session partitioning rules, then the capacity to transmit diverse ESG data is improved, but confusion occurs in reception terminals due to lack of detailed guidelines

Engineering Contradiction:

ImproveESG data transmission capacityVSAvoidReception terminal operation clarity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent changes the parameter of rule representation from abstract partitioning concepts to concrete, detectable rule types (valid period rule, ServiceURI rule, dateTime rule) that terminals can identify and process systematically, resolving the confusion while maintaining multiple-stream capability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary classification mechanism that detects and categorizes session partitioning rules into specific types, serving as a mediator between the complex multiple-stream transmission system and the terminal reception process, thereby clarifying operations without limiting transmission versatility

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If the amount of ESG data increases, then the information completeness is improved, but the data processing time of the reception terminal increases

Engineering Contradiction:

ImproveESG data volumeVSAvoidData processing time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The patent segments ESG data reception into distinct sessions with applicable partitioning rules, allowing the terminal to process data in organized units rather than as a monolithic block, thereby reducing overall processing time while handling increased data volume

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary detection and classification of session partitioning rules before full data processing, enabling the terminal to prepare appropriate processing strategies in advance and avoid time-consuming analysis during actual data reception

Inventive Principle:

Principle #10Preliminary action

AI summary

A method is disclosed for efficiently receiving Electronic Service Guide (ESG) data for a Digital Video Broadcasting-Handheld (DVB-H) broadcast service in a DVB-H reception terminal. When ESG data to which session partitioning rules are applied is received in a multiple-stream mode, session-by-session rules are detected. On the basis of the rules, sessions in which actual ESG data is carried are classified by roles required to provide the broadcast service. The associated ESG data from the sessions is acquired and stored. Since ESG data can be efficiently received by providing detailed guidelines for receiving the ESG data based on a session partitioning rule, a reception scheme of the DVB-H reception terminal can be significantly improved.
