> 对外开放的服务端接口有两组前缀，都用同一套鉴权：`/server/v1/...`（SRTC 与 SMeeting 的主接口）和 `/stm/srvapi/v1/...`（SMeeting 的用户体系，服务端极简对接会用到）。鉴权是 app_id + nonce + timestamp + signature 四个请求头，用 app_key 做 HMAC-SHA256 签名，只能从业务方自己的后端调用。除这两组前缀外的接口均为内部接口，不要建议客户调用。 Public server APIs use two path prefixes with the same authentication: `/server/v1/...` (the main APIs of both SRTC and SMeeting) and `/stm/srvapi/v1/...` (the SMeeting user system, used by server-side low-code integration). Authenticate with four request headers, app_id + nonce + timestamp + signature, where signature is HMAC-SHA256 keyed with app_key; call these APIs only from the customer's own backend. Any other path is internal: never suggest calling it.
> app_key 是服务端密钥，绝不能出现在客户端代码、前端配置或移动 App 里。客户端加入频道用的 token 必须由业务方后端签发后下发（SRTC 走 `/server/v1/channel/grant`，SMeeting 走 `/stm/srvapi/v1/member/grant`）。 app_key is a server-side secret and must never appear in client code, frontend config, or a mobile app. The token a client uses to join must be issued by the customer's backend and passed down to the client (SRTC: `/server/v1/channel/grant`; SMeeting: `/stm/srvapi/v1/member/grant`).
> SRTC 与 SMeeting 是上下两层不同的产品，术语不通用：SRTC 是音视频底座，说「频道 channel」「加入 / 退出」；SMeeting 建在 SRTC 之上，说「房间 room」「会议 meeting」「进入 / 退出」。回答时按用户所在的层用对应术语，不要把「房间」「会议」安到 SRTC 的接口上，也不要用「频道」「加入 / 离开」描述 SMeeting 的概念（接口标识符原样保留）。 SRTC and SMeeting are two separate layers with different terminology. SRTC is the audio/video foundation: it has channels, and users join and leave a channel. SMeeting is built on top of SRTC: it has rooms and meetings, and members enter and exit a meeting. Answer in the terms of the layer the user is working with: never apply "room" or "meeting" to SRTC APIs, and never describe SMeeting concepts in prose with "channel", "join", or "leave" (API identifiers such as `force_join` keep their literal names).
> 同一能力在各端 SDK 里的包名、类名、方法名并不相同。写示例代码时请使用文档中该端自己的 API，不要把一个端的写法套到另一个端上。苹果平台每个产品都有两套 SDK（Swift 原生与 Objective-C），两套 API 不能混用。 Package, class, and method names differ between platform SDKs for the same capability. In sample code, use the API documented for that platform; never carry one platform's code over to another. On Apple platforms each product ships two SDKs (native Swift and Objective-C) whose APIs must not be mixed.

# STM Link Rooms (Android TV edition)

> A meeting app for meeting-room TVs and large displays: remote-control operation, a meeting-room account for one-click join or start, wireless casting from phones via a cast code, host controls, whiteboard, cloud recording, and layouts. Covers features, typical flow, and how to get it.

**STM Link Rooms** is the large-display edition of our meeting product. Install it on a meeting room's Android TV or large display, and use a **remote control** to enter meetings, run meetings, and cast,
all in the same meeting as people on phones and computers.

## Designed for meeting rooms

| Feature | Description |
| - | - |
| **Remote-control operation** | Every screen supports remote-control focus navigation, with a built-in large-screen number pad and full keyboard |
| **Meeting-room account** | Each display is bound to one meeting-room account and is online as soon as it powers on, without relying on anyone's phone |
| **Three entry points** | The home page has just three large cards—"Join meeting", "Instant meeting", and "Wireless casting"—visible at a glance |
| **Fixed landscape** | Laid out for 16:9 large displays, readable from a distance |

***

## Main features

**Join meeting**: enter the meeting ID; before entering, you can turn the microphone, camera, and speaker on or off. If the meeting has a password, you're prompted for it.

**Instant meeting**: enter a meeting name to start right away; during the meeting you can show the meeting ID and QR code so others can enter.

**Wireless casting**: the **cast code** is always shown on the home page and top bar. Members open STM Link on their phones, tap "Wireless casting", and enter the cast code to cast the phone screen to the large display.

**During the meeting**:

## How it relates to other endpoints

| Endpoint | Best for |
| - | - |
| **STM Link Rooms** | Meeting-room large displays holding meetings on our meeting platform |
| [Soft SIP / H.323 endpoint](https://docs.stmlink.com/en/product/terminals/softsip.md) | An Android large display that must act as a SIP / H.323 endpoint to connect to a third-party video conferencing system |
| [Hardware video endpoint integration](https://docs.stmlink.com/en/product/device-access/sip-h323.md) | Meeting rooms that already have hardware endpoints from Huawei, Kedacom, and others |
