+# APTV Live Source Builder
+
+自动构建 APTV 直播源，支持央视、卫视、地方台，每天自动更新、过滤可用源、去重。
+
+## 功能特性
+
+- ✅ 自动抓取公开直播源
+- ✅ 央视、卫视、地方台分类整理
+- ✅ 可用性检测（HTTP 状态码 + 超时）
+- ✅ 自动去重（基于 URL 和频道名）
+- ✅ 生成标准 M3U 播放列表
+- ✅ 支持 GitHub Actions 每天自动更新
+
+## 目录结构

+        └── daily-update.yml
+```
+
+## 快速开始
+
+### 1. 安装依赖
+
+```bash
+pip install -r requirements.txt
+```
+
+### 2. 运行脚本
+
+```bash
+python main.py
+```
+
+生成的播放列表位于 `output/live.m3u`。
+
+### 3. 在 APTV 中使用
+
+将 `output/live.m3u` 上传到你的服务器或使用 GitHub Raw 链接，在 APTV 中添加该 M3U 地址即可。
+
+## 配置说明
+
+编辑 `config.py` 可调整：
+
+- `TIMEOUT`：检测超时时间（秒）
+- `MAX_WORKERS`：并发线程数
+- `ENABLE_FILTER`：是否启用可用性过滤
+- `ENABLE_DEDUP`：是否启用去重
+
+## 自动更新
+
+项目已包含 GitHub Actions 工作流，每天 UTC 0 点自动运行并提交更新后的 `output/live.m3u`。
+
+## 自定义源
+
+在 `sources/` 目录下添加 `.txt` 文件，每行格式：
+
+```
+频道名,URL
+```
+
+例如：
+
+```
+CCTV-1,http://example.com/cctv1.m3u8
+```
