在看视频、玩游戏、共享图片,甚至办公(包括 Microsoft PowerPoint* 演示)时使用多个屏幕越来越普遍。 但是用户如何使用第二个屏幕取决于具体的设备和操作系统。

本文将讨论排在前三位的技术 — Apple AirPlay*、Google Chromecast* 和 Wi-Fi Alliance Miracast*(该项技术采用英特尔® 无线显示技术 (英特尔® WiDi))之间的区别,并从开发人员的角度概括介绍每项技术的优势和劣势。

随着主设备越来越小,理想的显示屏尺寸越来越大。 通过观察早期的两个用例(小型设备以无线方式在更大的屏幕上显示其内容;以及智能电视显示互联网的内容),您可以了解专有标准和开放标准是如何产生的。 我在本文中讨论的每项技术都面临着不同方面的挑战,而每项技术都以各自的操作系统、设备和独特特性赢得了市场的认可。
