Hint-Based Media Streaming Interleaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media content streaming technologies face inefficiencies in throughput, storage requirements, and latency, particularly when handling multiple streams and diverse media types, due to limitations in packet construction and multiplexing protocols like RTMP.
Innovation Solution
The use of hint information, including message headers and metadata tracks, to optimize media content streaming by interleaving audio and video data, reducing duplication, and employing RTMP for efficient transmission, thereby enhancing throughput and reducing storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional RTMP protocols are used for media streaming, then reliable delivery is ensured, but throughput is limited and storage requirements increase
Solution Approach 1:
The patent segments media content into discrete samples with associated hint information, allowing selective transmission and processing. Each media sample is divided into manageable units with metadata, enabling efficient multiplexing and reducing redundant storage requirements while maintaining reliable delivery through structured packetization
Solution Approach 2:
The patent extracts essential hint information (timestamps, durations, sequence numbers) from media streams and separates this metadata from the actual media data. This extraction allows the system to transmit only necessary control information alongside media samples, reducing overall data volume and storage needs while preserving the ability to deliver content reliably through the extracted timing and sequencing data
2Adaptability or versatility
If multiple media streams are transmitted simultaneously, then content variety is improved, but packet construction complexity increases
Solution Approach 1:
The patent merges multiple media streams by multiplexing different audio and video samples into a unified data structure with consistent hint information formats. This combining approach allows diverse media types to be transmitted simultaneously using standardized packet construction rules, reducing complexity through uniform processing while maintaining stream variety
Solution Approach 2:
The patent creates a universal packet structure that can accommodate multiple media types (audio, video, text) through a single standardized format with hint information fields. This multi-functional packet design eliminates the need for separate construction procedures for different media types, reducing complexity while enabling diverse content transmission
3Productivity
If hint information is added to media samples, then transmission efficiency is improved, but data volume increases
Solution Approach 1:
The patent applies local quality by adding hint information only where needed for synchronization and timing control, rather than duplicating entire media samples. The hint data (timestamps, durations, sequence numbers) is selectively attached to specific media samples, providing enhanced transmission efficiency for critical timing information while minimizing unnecessary data volume through targeted metadata addition
Data Source
AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for media content streaming can include communicating with a remote device to stream media content to the remote device, accessing hint information associated with the media content, and transmitting a data stream to the remote device based on the hint information. The hint information can include message headers arranged in a transmission order sequence that correspond to respective media data samples. Accessing hint information can include accessing a hint segment that includes the message headers interleaved with the media data samples.
