Chat Replay Operation Guide

1. Feature Overview

Feature Info	Description
Feature Name	Chat Replay
Feature Overview	[Chat Replay] is one of the features for restoring the live streaming experience. While watching a replay, users can also feel the discussions of other viewers in the live room at the corresponding video content moment, creating a sense of resonance. Meanwhile, floating danmaku provides a sense of companionship, aiming to increase dwell time and revenue conversion.
Purpose	Use active danmaku and chat messages to give replay viewers a sense of companionship, occasionally creating resonance, thereby increasing dwell time and improving revenue conversion.
Use Cases	Scenario 1: During a corporate training department's live stream, the teaching assistant sends supplementary knowledge point explanations to the interactive area when the instructor covers a specific topic. The assistant wants students watching the replay to also see these explanations at the same knowledge point, enhancing understanding. Thus, the chat replay feature is used, greatly improving training effectiveness. With danmaku companionship, watching replays is no longer boring. Scenario 2: In low-cost live courses, education clients intersperse purchase links or QR codes for high-cost courses. However, during replays, such messages have already been scrolled away. Clients want to maintain high conversion rates during replays, so they decide to use the chat replay feature, ensuring sustained and stable conversion and revenue during replays.
