我们在智能设备上使用各种多媒体应用程序来消费多媒体内容，与同行交流，并现场直播我们的活动。本文研究了不同类型的多媒体应用对不同的媒体输入/输出设备，如摄像头、麦克风和扬声器的使用情况，并引入了多媒体情境的概念。我们的测量结果导致了一种称为MediaSense的感知算法，它可以感知多个I/O设备的状态，并实时识别移动设备的11个多媒体上下文。该算法将存储的内容回放与流、实况广播与本地录制、以及来自移动设备上的GSM/VoLTE呼叫的对话式多媒体会话区分开来。
We use various multimedia applications on smart devices to consume multimedia content, to communicate with our peers, and to broadcast our events live. This paper investigates the utilization of different media input/output devices, e.g., camera, microphone, and speaker, by different types of multimedia applications, and introduces the notion of multimedia context. Our measurements lead to a sensing algorithm called MediaSense, which senses the states of multiple I/O devices and identifies eleven multimedia contexts of a mobile device in real time. The algorithm distinguishes stored content playback from streaming, live broadcasting from local recording, and conversational multimedia sessions from GSM/VoLTE calls on mobile devices.
