Latency Settings
Play ISR allows for a user configurable latency setting to improve the interaction with real-time video. Leverage these settings as a tool, acknowledging the conscious trade of low latency for playback consistency and/or quality in a given situation.
Latency Setting | Buffer (ms) | Description |
|---|---|---|
Ultra-Low | 0 | Use the Ultra-Low latency setting for situations requiring a minimum glass-to-glass viewing latency for real-time video. In addition to having a minimal buffer, this setting also ignores timing of video frames and displays them as fast as possible. Note Selecting Ultra-Low latency can introduce undesirable and inconsistent playback behavior for stream sources having poor pacing, or variable frame timing. In ISR scenarios where no audio is included, leverage the "Disable Audio" setting to further reduce latency by eliminating audio-video synchronization buffering. See Play ISR Settings. |
Low | 60 | Use the Low latency setting for stream sources with some perceptible jitter to smooth the playback experience. |
Balanced | 160 | Balance is set as the default latency setting. This latency level has a small input decoder buffer to accommodate network and/or encoding jitter common in video streaming applications. Use the Balanced setting for general usage of PlayISR for a wide-ranging set of source streams. |
High Quality | 260 | Use the High Quality setting for the smoothest playback of audio / Video / Metadata for streams with high skew between essences within source data streams. |
