Priority Stream Segmentation in Paused Multimedia Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public video distribution systems that allow pausing or delaying of video streams often inadvertently pause or delay high-priority data streams, such as security or safety feeds, which can lead to safety issues and a false sense of security.
Innovation Solution
A system and method that allows selected priority data streams to be processed and displayed in real-time even when the main system is paused, with an alert notification if the priority feed is interrupted, using a multimedia content decoder with an input priority detector to identify and prioritize data streams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system pauses or delays all video streams, then the main content can be buffered and controlled, but high-priority data streams such as security or safety feeds are inadvertently delayed, compromising reliability
Solution Approach 1:
The system segments data streams by priority level, separating high-priority streams (security, safety) from standard streams. This segmentation allows differential handling where standard streams can be paused while high-priority streams continue uninterrupted, resolving the contradiction between pause control and security feed continuity
Solution Approach 2:
The patent applies local quality by assigning different quality attributes to different parts of the system - high-priority streams receive continuous processing quality while standard streams receive buffered processing quality. This localized quality differentiation enables pause functionality for standard content while maintaining reliability for critical security feeds
2Reliability
If the system processes all streams in real-time, then high-priority data maintains continuity, but the system loses the ability to buffer and control standard content
Solution Approach 1:
By segmenting the data stream processing into priority-based queues, the system can maintain real-time processing for high-priority streams while allowing standard streams to be buffered. This segmentation resolves the contradiction by enabling simultaneous real-time handling of critical data and buffered handling of standard content
Solution Approach 2:
The system dynamically adjusts processing behavior based on stream priority and system state. High-priority streams dynamically receive continuous processing while standard streams dynamically switch to buffered mode, allowing the system to maintain both reliability for critical feeds and buffering capability for standard content
3Adaptability or versatility
If the system merges security systems with satellite/cable/internet content, then system versatility increases, but the complexity of managing different priority streams increases
Solution Approach 1:
The patent implements a universal priority-based processing framework that handles multiple data sources (satellite, cable, internet, security feeds) through a common mechanism. This universal approach increases adaptability while managing complexity through standardized priority tagging and processing rules applicable to all stream types
Data Source
AI summary
A pausable system that processes multi-channel, multimedia content including a multimedia content delivery device having a priority detector for determining priority multimedia content and a decoder that can decode the priority content while the system is in a paused state. The system can also output an indicator if a priority multimedia content becomes disrupted based on a received rate compared to an embedded rate. The priority detector can also determine if the priority content is intended for a particular recipient before processing by the multimedia content delivery device.
