-## MP2 Audio Software Decoding
-
-Most IPTV HD and SD channels use MPEG-1 Layer 2 (MP2) audio encoding. Some browsers (such as iOS Safari) do not natively support MP2 decoding, causing programs to fail to play or play with video only (no audio).
-
-The player has built-in MP2 audio software decoding capability:
-
-- **iOS Safari**: Enabled by default. Testing shows most programs can now play normally.
-- **Other browsers**: Disabled by default. You can manually enable the "MP2 Audio Software Decoding" option by clicking the sidebar settings button.
-
-> [!NOTE]
-> Audio software decoding relies on browser Web Workers and WebAssembly for background decoding, which consumes some computational resources and may cause slight heating on mobile devices — this is normal. Additionally, due to browser limitations, background playback on mobile devices is not supported when using software decoding.
-
 ## PWA Support and Add to Home Screen
 
 The built-in web player supports PWA (Progressive Web App). You can add the player page to your device's home screen (including phones, tablets, computers, and LG webOS smart TVs) and launch it like a native app for a full-screen, immersive viewing experience.

-## MP2 音频软解
-
-IPTV 大多数高清、标清频道使用 MPEG-1 Layer 2 (MP2) 音频编码，一些浏览器（例如 iOS Safari）无法原生支持 MP2 解码，导致节目无法播放，或者只有画面没有音频。
-
-播放器内置了 MP2 音频软解能力：
-
-- **iOS Safari**：默认启用，经测试大多数节目已经可以正常播放
-- **其他浏览器**：默认关闭，可以点击侧边栏设置按钮手动启用「MP2 音频软解」选项
-
-> [!NOTE]
-> 音频软解依赖于浏览器 Web Worker 和 WebAssembly 在后台解码，会占用一些计算资源，在手机上可能会产生轻微发热，这是正常现象。此外，受限于浏览器，使用软解时在手机上无法保持后台播放。
-
 ## PWA 支持与添加到主屏幕
 
 内置 Web 播放器支持 PWA（Progressive Web App）。你可以将播放器页面添加到设备主屏幕（包括手机、平板、电脑，以及 LG webOS 智能电视），像打开原生应用一样一键进入，获得全屏、沉浸式的观看体验。
