When you use the Workout app, Apple Watch measures your heart rate continuously during the workout and for 3 minutes after the workout ends to determine a workout recovery rate. I believe that is what is meant by "streaming".
In addition, Apple Watch measures your heart rate throughout the day when you’re still, and periodically when you’re walking. The time between these measurements will vary. These are "background" readings
