Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current technologies face challenges in distinguishing and providing ultra high definition television (UHDTV) service from high definition television (HDTV) service due to increased data requirements, exceeding physical channel capacity, necessitating a method to differentiate between service types.

Innovation Solution

An apparatus and method that includes a television service sorting unit to allocate new service types based on resolution and codec profiles, adding distinguishing information to component descriptors, allowing for the differentiation of UHDTV service from HDTV service by using a sorting method determining unit, new TV service type allocating unit, and adding unit to manage UHDTV stream information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If UHDTV service data is transmitted using existing HDTV service type allocation, then the service can be provided through current channel capacity, but the service type cannot be distinguished from HDTV service and channel capacity is exceeded

Engineering Contradiction:

Improveservice type distinctionVSAvoiddata amount

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent changes the service type parameter allocation by defining new service type values (e.g., 0x03 for 4K UHDTV, 0x04 for 8K UHDTV) distinct from existing HDTV service types (0x01 for SD, 0x02 for HD). This parameter change enables clear distinction between HDTV and UHDTV services while accommodating the increased data requirements of UHDTV through dedicated service type allocation.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If new service types are allocated for UHDTV, then service distinction is achieved, but the service type allocation complexity increases

Engineering Contradiction:

Improveservice type distinctionVSAvoidservice type allocation

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the service type space by allocating specific service type values for different UHDTV resolutions (4K, 8K) separately from HDTV service types. This segmentation creates a structured allocation scheme where HDTV services (0x01, 0x02) are distinct from UHDTV services (0x03, 0x04, 0x05), simplifying the distinction process despite the increased number of service types.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension to service type allocation by adding resolution-based differentiation (4K, 8K) to the existing service type system. This dimensional expansion allows UHDTV services to be distinguished not only by service type value but also by resolution characteristics, providing a more comprehensive classification framework.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A method and apparatus for providing ultra high definition television service is provided. The apparatus for providing UHDTV service sets up a type of the UHDTV service as a first type of HDTV service and a second type different from that of the HDTV service in an environment of the UHDTV service and the HDTV service coexist.
