In the context of AVYCON, a popular brand for surveillance cameras and video equipment, “main stream” and “sub stream” refer to two different video streams that a camera can produce simultaneously for various purposes.
1. Main Stream:
– This is the primary video feed, usually with the highest resolution and the best video quality.
– It’s typically used for recording or viewing high-quality footage, as it provides a detailed image.
– The main stream is used for applications where video quality is a priority, like detailed monitoring or playback.
2. Sub Stream:
– This is a secondary, lower-quality video feed compared to the main stream.
– It’s often used for live viewing on bandwidth-limited networks or for mobile viewing, where lower resolution and smaller file sizes are necessary to reduce lag or buffering.
– The sub stream typically has reduced resolution and lower bitrate to make it more efficient for remote access or less powerful devices.
In essence, the main stream is for high-quality recording and playback, while the sub stream is for more bandwidth-efficient live viewing or when using devices that can’t handle high-definition video streams.
