# How to Automatically Mix Live and Recorded Video for Online Streaming

> This patent describes a system for dynamically creating and updating a playlist for a live media stream that seamlessly combines both real-time video feeds and pre-recorded content based on a schedule and specific triggers.

- **Patent:** US 12739460
- **Original title:** Publishing disparate live media output streams in mixed mode
- **Granted:** 2026
- **Status:** Active
- **Times cited:** 0
- **Field:** telecommunications, software, consumer_electronics, media_streaming

## What it does

The system generates a 'disparate live media output stream manifest,' which acts like a dynamic playlist for a mixed media broadcast. This manifest is built using a 'programming schedule,' an 'additional parameter,' and an initial content source, which can be either a 'live input stream manifest' (for real-time video) or a 'pre-encoded media asset manifest' (for pre-recorded video). Based on a 'first transition' or a 'second transition,' the system inserts new content, whether live or pre-recorded, into this output manifest. It then 'switches' the currently playing media to the newly inserted content and 'modifies' the manifest to reflect this change. For example, a streaming service could schedule a live sports event, then transition to a pre-recorded highlight reel, and then back to a live post-game analysis, all managed automatically by this system.

## What it does NOT cover

- Does not cover systems that only play pre-recorded content without mixing live streams.
- Does not cover systems that only broadcast a single continuous live stream without inserting pre-recorded assets.
- Does not cover manual switching between content without a manifest-driven system.
- Does not cover systems that do not modify the manifest to reflect content changes.
- Does not cover mixing non-media data streams, focusing specifically on 'media output stream'.

## The clever bit

The novelty lies in the dynamic generation and continuous modification of a single output stream manifest that seamlessly integrates both 'disparate' live and pre-encoded media assets. This process is driven by scheduled 'transitions' and 'additional parameters,' allowing for complex, automated programming that adapts in real-time.

## Real-world examples

1. Virtual TV channels on streaming platforms
2. Online news broadcasts mixing live reports and pre-recorded segments
3. Live event streaming with pre-roll and mid-roll content insertion
4. Hybrid online learning platforms combining live lectures with recorded modules

## Why it matters

This technology is crucial for modern online broadcasting, allowing platforms to create flexible, TV-like channels that combine real-time events with on-demand content. It enables dynamic programming schedules for streaming services and virtual channels, offering a more engaging and varied viewing experience. This automation reduces the need for constant manual intervention in live production.
