Scalable Video Buffer Parameter Timing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to determine whether the decoding process of scalable video coding is performed by a single decoding device or multiple devices due to the difficulty in detecting HRD parameters for each layer or time layer.
Innovation Solution
An image processing device and method that receives a bitstream with buffer management parameter information indicating whether the HRD parameter is for decoding a corresponding layer or both the corresponding layer and a lower layer, allowing proper timing for the decoding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If HRD parameters are designated for each layer in scalable video coding, then decoding can be performed at proper timing, but it becomes difficult to detect whether the decoding process is performed by a single decoding device or multiple devices
Solution Approach 1:
The patent introduces a buffer management parameter as an intermediary element that bridges the gap between HRD parameter designation and decoding device configuration detection. This parameter acts as a mediator that carries information about both the timing requirements and the number of decoding devices, allowing the system to resolve the contradiction by using this intermediate data structure to convey multiple pieces of information simultaneously
2Productivity
If scalable video coding is performed with multiple layers, then encoding efficiency is improved, but the complexity of managing decoding parameters increases
Solution Approach 1:
The patent merges multiple parameter management functions into a single buffer management parameter structure. Instead of separately managing HRD parameters for each layer and separately tracking decoding device configurations, the invention combines these functions into one unified parameter that handles both aspects, thereby reducing the overall complexity while maintaining encoding efficiency

AI summary
Provided is an image processing device including a receiving section configured to receive a bitstream obtained by encoding an image having at least one layer and buffer management parameter information of each layer indicating at least one of that a parameter for managing a decoder buffer is a parameter for performing a decoding process of only a corresponding layer and that the parameter for managing the decoder buffer is a parameter for performing a decoding process of a corresponding layer and a lower layer, and a decoding section configured to decode the bitstream received by the receiving section and generate an image.
