多终端与投屏Devices and casting

同一账号，换一块屏继续看。第一期以响应式网页为主，并支持把正在播放的节目投到智能电视。原生电视应用和 FAST 频道不是第一期范围。 One account, pick up on another screen. Phase one is a responsive website, plus the ability to cast a program that is already playing to a smart TV. A native TV app and FAST channels are not in phase one.

Web

第一期核心：电脑与手机浏览器都能完整观看、发布与管理收入说明。Phase-one core: a complete watch, publish, and earnings-notes experience in desktop and phone browsers.
登录后将出现「继续观看」与片单，进度与同一账号下的其他终端同步。当前登录为演示。After sign-in, Continue watching and lists will appear, with progress synced across screens on the same account. Sign-in is a demo today.
不做只能在某个浏览器插件里观看的限制。There is no requirement to watch only inside a browser extension.

手机Phone

第一期可先用响应式网页完成观看、投屏与发布。Phase one can use the responsive site for watching, casting, and publishing.
正式手机 App 建议二期交付：系统投屏、在授权范围内的离线下载、推送和更顺手的创作者中心。A native phone app is proposed for a later phase: system casting, authorized offline downloads, notifications, and a more fluent Creator Center.
离线下载须遵守授权与广告规则，不得把下载当成可二次分发的文件复制。Offline downloads, when offered, must follow license and advertising rules, and are not a file you may redistribute.

投屏与电视Casting and TV

第一期：用手机或电脑经系统投屏到智能电视（如 AirPlay、Chromecast 及等效能力，以设备实际可用接口为准）。这是「在手机上看，再投到电视」的可落地做法。Phase one: cast from a phone or computer with system controls (such as AirPlay, Chromecast, or an equivalent, depending on the device). That is the practical way to watch on a phone and send the picture to a TV.
二期：考虑原生智能电视应用，用遥控器操作、继续观看和登录同步。A later phase may add a native smart-TV app, with remote control, Continue watching, and sign-in sync.
更后：精选节目才可能编成 FAST 频道，再评估进入 Roku、Prime Video、LG 等货架。那不是第一期已上线的能力。Still later, featured programs might be assembled into a FAST channel, and only then would shelves such as Roku, Prime Video, or LG be evaluated. That is not a phase-one launch item.
电视端依然显示 AI 标识与年龄分级；打赏可用手机配套完成支付（正式支付随后接入）。The TV presentation should still show the AI label and age rating. Tips can be completed on the companion phone once official payments are connected.
