Solution Overview

Problem

Existing technologies face challenges in providing high frame frequency services due to limitations in receiver performance, leading to increased costs and barriers to adoption.

Innovation Solution

A TV transmitting/receiving system that classifies image data into multiple layers, with each layer having a specific frame frequency, allowing for easy recognition and decoding of frame frequencies on the receiving end.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the receiver supports high frame frequency services, then the service quality is improved, but the receiver cost increases

Engineering Contradiction:

Improveframe frequencyVSAvoidreceiver cost

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The image data is divided into multiple layers with different frame frequencies. Each layer can be independently decoded, allowing receivers to select only the layers they can handle. This segmentation enables low-cost receivers to decode lower frame frequency layers while high-performance receivers can decode additional high frame frequency layers, resolving the contradiction between service quality and receiver cost.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple services are provided simultaneously, then service versatility is improved, but system complexity increases

Engineering Contradiction:

Improveservice versatilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transmitting device encodes image data into multiple layers that can serve different frame frequency requirements simultaneously. A single transmission stream contains all necessary information for both low and high frame frequency services, allowing the system to provide multiple services without requiring separate transmission systems, thus achieving versatility without proportional complexity increase.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If frame-decimated playback is used, then playback flexibility is improved, but fine decimation capability is reduced

Engineering Contradiction:

Improveplayback flexibilityVSAvoiddecimation precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

Instead of decimating frames from a single layer, the invention adds a layer dimension to the data structure. Multiple layers with different frame frequencies are created, allowing precise control over playback frame frequency by selecting specific layers. This dimensional approach enables fine-grained decimation control that was not achievable with simple frame skipping methods.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Provided is a transmitting device including a hierarchical classification section that classifies image data of each picture constituting moving image data into a plurality of layers, an image coding section that codes the classified image data of each layer, and generates a video stream holding the coded image data of each layer, and a transmitting section that transmits a container in a prescribed format that includes the generated video stream. The image coding section performs coding so that a referenced picture belongs to a layer of referencing image data and/or a layer lower than the layer of the referencing image data.
