Video Packager Validation With Default Segment Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video stream transmissions are susceptible to errors such as packet loss and corruption during transport, leading to playback issues and maintenance requirements for service providers.
Innovation Solution
A video packager maintains a default video output and performs validation checks on encoded video data, packaging playable video data or default output based on validation parameters to ensure error-free delivery to playback devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted through the content delivery network, then video content can be delivered to playback devices, but data may be lost or corrupted during transmission
Solution Approach 1:
The system performs validation checks on video segments before packaging and transmission to playback devices. By detecting corrupted or lost packets in advance and replacing them with default segments, the system prevents transmission of defective data, thereby resolving the contradiction between delivering video content and ensuring data integrity during transmission.
2Reliability
If the video packager processes and validates all received video data, then playback errors are prevented, but processing time and system complexity increase
Solution Approach 1:
The video packager automatically performs validation checks on received video segments and autonomously replaces corrupted segments with default video segments without requiring external intervention. This self-service mechanism maintains playback stability while managing system complexity through automated fault tolerance rather than complex manual validation systems.
3Reliability
If the system uses validation checks on received video data, then corrupted data is detected, but processing time increases
Solution Approach 1:
The validation system performs checks on critical portions of video segments rather than exhaustive validation of every byte. This partial validation approach detects the most common corruption types (lost packets, header errors) while minimizing processing time overhead, thereby balancing data quality assurance with processing efficiency.

AI summary
Disclosed are various systems and methods for fault tolerant video packaging and transmission. A video packager may receive one or more video content transmissions from a transcoder, and may identify deficient segments, packets, or other portions of the video content transmission. The video packager may also maintain or have access to a default video output that is free of the identified deficiencies. For example, the default video output can include one or more segments of video data comprising a blank or solid color frame, or a still image. The deficient data may be determined based on validation parameters. If the validation parameters are satisfied, the received data is packaged and transmitted. Otherwise, the default video output is packaged to replace deficient portions, and transmitted instead of the received video content.
