Digital TV was introduced with promises for higher quality displays and converging internet services which require more computing power and complex software systems. Such complexity entails a prolonged startup time that is similar to booting a computer system. In this paper, we propose two approaches to reduce the startup time of digital TV. Based on the suspend-resume technique employed in many commodity operating systems, our mechanisms replace the cold startup process of digital TV with the resuming from a suspend image. We also analyze the bottlenecks in the startup process and suggest hardware supports to improve the startup time. The proposed approaches reduce the startup time of digital TV by about 50%.
