+视频合集和视频列表虽然在哔哩哔哩网站交互上行为类似，但在接口层级是两个不同的概念，程序配置中需要对两者做出区分。
 
-在调试过程中我注意到视频列表的 ID 可以通过某种规则转换为视频合集的 ID，从而成功调用视频合集的接口，但由于不清楚具体的转换策略，在 bili-sync 的实现中还是将其当成两种类型处理。
+目前 B 站绝大部分内容都是视频合集（Season），视频列表（Series）是古早的功能，现在已经不常见了。
 
-## 区分方法
+## 配置形式与区分方法
 
-这两种类型可以很容易地通过如下手段区分：
-1. 两者的名称前缀不同，视频合集会有显式的“合集”字样
-2. 两者的图标不同
+新版本 b 站网页端已经对两种类型做了初步整合，将需要的参数展示在了视频合集/视频列表的 URL 中，不再需要手动查看接口。URL 的路径格式为：
 
-如下图所示，“合集【命运方舟全剧情解说】”是视频合集，而“阿拉德冒险记”是视频列表。
-![image](./assets/collection.webp)
 
-在 bili-sync 的设计中，视频合集的 key 为 `season:{mid}:{season_id}`，而视频列表的 key 为 `series:{mid}:{series_id}`。
+```
+/{mid}/lists/{id}?type={season/series}
+```
 
-## 参数获取

-了解了区分方法后，我们可以通过如下步骤获取视频合集/视频列表的信息。

+一般情况下，b 站会为视频、音频流提供一个 baseUrl 与多个 backupUrl，程序默认会按照 baseUrl -> backupUrl 的顺序请求，依次尝试下载。
+
+如果启用 CDN 排序，那么程序不再使用默认顺序，而是将所有 url 放到一起统一排序来决定请求顺序。排序优先级从高到低为：
+
+1. 服务商 CDN：`upos-sz-mirrorxxxx.bilivideo.com`
+2. 自建 CDN：`cn-xxxx-dx-v-xxxx.bilivideo.com`
+3. MCDN：`xxxx.mcdn.bilivideo.com`

-## `watch_later`

-
-```toml
-enabled = true
-path = "/home/amtoaer/Downloads/bili-sync/稍后再看"
-```
-
-## `concurrent_limit`
-
-对 bili-sync 的并发下载进行多方面的限制，避免 api 请求过于频繁导致的风控。其中 video 和 page 表示下载任务的并发数，rate_limit 表示 api 请求的流量限制。默认取值为：
-```toml
-[concurrent_limit]
-video = 3
-page = 2
-
-[concurrent_limit.rate_limit]
-limit = 4
-duration = 250
-```
-
-具体来说，程序的处理逻辑是严格从上到下的，即程序会首先并发处理多个 video，每个 video 内再并发处理多个 page，程序的并行度可以简单衡量为 `video * page`（很多 video 都只有单个 page，实际会更接近 `video * 1`），配置项中的 `video` 和 `page` 两个参数就是控制此处的，调节这两个参数可以宏观上控制程序的并行度。
-
-另一方面，每个执行的任务内部都会发起若干 api 请求以获取信息，这些请求的整体频率受到 `rate_limit` 的限制，使用漏桶算法实现。如默认配置表示的是每 250ms 允许 4 个 api 请求，超过这个频率的请求会被暂时阻塞，直到漏桶中有空间为止。调节 `rate_limit` 可以从微观上控制程序的并行度，同时也是最直接、最显著的控制 api 请求频率的方法。
-
-据观察 b 站风控限制大多集中在主站，因此目前 `rate_limit` 仅作用于主站的各类请求，如请求各类视频列表、视频信息、获取流下载地址等，对实际的视频、图片下载过程不做限制。
+该页主要用于调整程序的请求与下载行为。
 
 > [!TIP]
-> 1. 一般来说，`video` 和 `page` 的值不需要过大；
-> 2. `rate_limit` 的值可以根据网络环境和 api 请求频率进行调整，如果经常遇到风控可以优先调小 limit。

+
+### 视频并发数、分页并发数
+
+视频并发数（video）和分页并发数（page）是控制 bili-sync 视频下载任务并发度的配置项。
+
+程序的处理逻辑是严格从上到下的，即程序会首先并发处理多个 video，每个 video 内再并发处理多个 page，程序的并发度可以简单衡量为 `video * page`（很多 video 都只有单个 page，实际会更接近 `video * 1`），`video` 和 `page` 两个参数就是控制此处的，调节这两个参数可以宏观上控制程序的并发度。
+
+### NFO 时间类型
+
+表示在视频 NFO 文件中使用的时间类型，可选值为收藏时间和发布时间。
+
+仅收藏夹视频会对这两项进行区分，其它类型的视频这两者取值完全相同。
+
+### 请求频率限制
+
+每个执行的任务内部都会发起若干 api 请求以获取信息，这些请求的整体频率受到请求频率的限制，使用漏桶算法实现。超过这个频率的请求会被暂时阻塞，直到漏桶中有空间为止。
+
+时间间隔（毫秒）与限制请求数共同表明的意思时：程序在每个时间间隔内最多允许多少个请求。调节这一项可以从微观上控制程序的并行度，同时也是最直接、最显著的控制 api 请求频率的方法。
+
+据观察 b 站风控限制大多集中在主站，因此目前请求频率限制仅作用于主站的各类请求，如请求各类视频列表、视频信息、获取流下载地址等，对实际的视频、图片下载过程不做限制。
+
+### 单文件分块下载
+
+单文件分块下载是指将单个视频文件分成多个小块进行下载，这可能有助于提高下载速度。
+
+程序会首先为这个文件预分配空间，接着将文件分成若干个大小相同的块，为每个块启动单独的异步任务并行下载。
+
+
+#### 下载分块数
+
+表示单个文件分成多少个小块，默认值为 4。
+
+#### 启动分块下载的文件大小阈值（字节）
+
+表示当单个文件大小超过多少字节时，才会启动分块下载。默认值为 20971520（20 MB）。
+
+如果文件过小，分块成本可能会超过分块下载带来的收益，因此使用该阈值决定下载策略。

 如果某些部分下载失败，status 字段会记录这些部分的失败次数，程序会在下次下载时重试。如果重试次数超过了设定的阈值，那么视频会被标记为下载失败，后续直接忽略。
