Video File Format Initialization Fragments Bandwidth Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video coding systems face challenges in maximizing bandwidth conservation and latency reduction, particularly in modern media delivery techniques like streaming and one-to-many distribution, where conventional file formats are not optimized for efficient data transmission and storage.
Innovation Solution
A new file format is introduced that allows for incremental data objects, fragmentation of presentations in time, and separate storage of initialization information, enabling efficient encoding and decoding processes, including the use of initialization fragments and patterns to facilitate decoding and display of video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional file formats are used for media delivery, then compatibility with existing systems is maintained, but bandwidth efficiency and latency are not optimized
Solution Approach 1:
The media presentation is divided into independently decodable segments or fragments, each containing complete initialization information and media data. This segmentation enables parallel processing and efficient bandwidth utilization while maintaining compatibility with existing decoding systems.
Solution Approach 2:
The patent introduces a new organizational dimension to file formats by separating initialization information from media data and allowing independent transmission of segments. This dimensional reorganization optimizes bandwidth efficiency without increasing system complexity.
2Loss of energy
If video data is coded at lower data rates to conserve bandwidth, then bandwidth efficiency improves, but decoding complexity and latency may increase
Solution Approach 1:
Initialization information is transmitted separately and stored before media data decoding begins. This preliminary action prepares the decoding system in advance, reducing latency during actual media playback while allowing aggressive compression for bandwidth conservation.
Solution Approach 2:
The patent introduces an intermediary initialization fragment that bridges the compressed media data and the decoding process. This intermediary contains all necessary parameters and configuration data, enabling efficient decoding of highly compressed segments without increasing latency.
3Adaptability or versatility
If existing file formats are used for streaming and one-to-many distribution, then system compatibility is maintained, but optimization for modern media delivery techniques is lost
Solution Approach 1:
The new file format design allows segments to serve multiple functions: they can be independently transmitted for streaming, combined for one-to-many distribution, and decoded with standard decoders. This multi-functionality provides adaptability to modern delivery techniques while maintaining ease of conversion through standardized structures.
Data Source
AI summary
A new file format for coded video data is provided. A decoder may identify patterns in the coded video data in order to make the decoding process and/or display of data more efficient. Such patterns may be predefined and stored at the decoder, may be defined by each encoder and exchanged during terminal initialization, or may be transmitted and/or stored with the associated video data. Initialization information associated with the fragments of video data may also provide for carouseling initialization updates such that the initialization fragments may indicate either that the initialization information should be updated or that the decoder should be re-initialized. Additionally, media files or segments may be broken into fragments and each segment may have an index to provide for random access to the media data of the segment.
