Abstract

The inventive system and method for preventing resource exhaustion while performing video rendering comprises calibrating resource utilization of operating parameters, obtaining input configuration comprising a priority order and source data, and controlling streaming and rendering frame rates by dropping data based on the input configuration. The operating parameters can comprise CPU, RAM, and GC usage. The source data can be resource utilization, a database and an application service. Dropping data can be performed using a throttling mechanism. In one embodiment, calibrating further comprises determining resource utilization using an input resolution and streaming at 1 FPS, determining resource utilization using the input resolution and streaming at 30 FPS, calculating an output resolution, if the output resolution does not exceed the input resolution, getting another input resolution, and determining resource utilization and calculating another output resolution, and determining resource utilization and calculating output resolution with rendering on.

Claims
