GUID-Embedded Transport Stream Metadata Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media content delivery systems face challenges in managing video on demand (VOD) packages, as they require complete metadata packages, leading to bandwidth issues and corruption when metadata is incomplete or outdated, necessitating frequent resending of entire packages.
Innovation Solution
Embedding globally unique identifiers (GUIDs) within media content transport streams allows for the retrieval of necessary metadata from external sources, eliminating the need for separate metadata packages and enabling updates without resending the entire VOD package, while also integrating parental control information and auxiliary data streams for enhanced content delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete VOD packages with metadata are sent from content providers, then metadata completeness is improved, but bandwidth usage increases and transmission time increases
Solution Approach 1:
The patent extracts metadata from the complete VOD package and sends it separately as metadata-only updates. This allows the main video content to be transmitted once, while metadata can be updated independently without retransmitting the entire package, reducing bandwidth consumption while maintaining metadata completeness.
Solution Approach 2:
The patent segments the VOD package into two independent components: the video content file and the metadata package. This segmentation allows them to be transmitted and managed separately, enabling efficient bandwidth usage where metadata can be updated without retransmitting the large video file.
2Reliability
If complete VOD packages are resent when metadata is incomplete or outdated, then metadata reliability is improved, but transmission time increases
Solution Approach 1:
The patent implements preliminary validation of metadata completeness at the content provider end before transmission. This preliminary check ensures that metadata is complete and current before being sent, preventing the need for retransmission and reducing overall transmission time while maintaining reliability.
Solution Approach 2:
By extracting and sending only metadata updates separately from the video content, the system can quickly transmit small metadata corrections without retransmitting the entire large VOD package, significantly reducing transmission time while maintaining metadata reliability.
3Ease of operation
If separate metadata packages are used, then metadata updates become complex and error-prone, but combining metadata with content increases bandwidth usage
Solution Approach 1:
The patent merges the video content file and metadata package into a single integrated VOD package structure that is transmitted together initially. This combination simplifies the delivery process and reduces the complexity of managing separate metadata files, while the system is designed to handle subsequent metadata updates efficiently without requiring full package retransmission.
Data Source
AI summary
Novel tools and techniques are provided for implementing media content delivery. In some embodiments, a globally unique identifier (“GUID”) associated with a particular media content might be embedded in headers of packets of a transport stream of the media content. When the transport stream is received by a user device, the GUID might enable retrieval of the necessary metadata (and/or updates of metadata) for enabling presentation of the media content. Alternatively or additionally, ratings or similar information can likewise be embedded in the headers of packets or I-frames of the transport stream, which enables a user (e.g., parent) to easily block or skip objectionable content from children who may be present. Alternatively or additionally, the transport stream may be combined with auxiliary data streams containing metadata and other associated auxiliary content to create a combined transport stream, to ensure no lost or corrupted media content during transmission.
