                 <p id="1v1"><apiname keyref="APPLICATION_SCENARIO_1V1"/>(2) This is applicable to the <xref keyref="one-to-one-live"/> scenario. To meet the requirements for low latency and high-quality video in this scenario, the SDK optimizes its strategies, improving performance in terms of video quality, first frame rendering, latency on mid-to-low-end devices, and smoothness under weak network conditions.</p>
-                <p id="liveshow"><apiname keyref="APPLICATION_SCENARIO_LIVESHOW"/>(3) This is applicable to the <xref keyref="showroom"/> scenario. In response to the high demands for first-frame rendering time and image quality, the SDK focuses on reducing first-frame rendering time and enhancing overall image quality, even in poor network conditions or on low-end devices.</p>
+                <p id="liveshow"><apiname keyref="APPLICATION_SCENARIO_LIVESHOW"/>(3) This is applicable to the <xref keyref="showroom"/> scenario. 针对该场景对首帧出图时间和画质清晰度的高要求，SDK 进行了策略调优，例如，默认开启音视频帧加速渲染来提升首帧出图体验，无需再额外调用 <xref keyref="enableInstantMediaRendering"/>，同时会默认开启 B 帧来确保较高的图像质量、提高传输效率。 此外，也增强了在弱网环境和低端设备上的画质和流畅度表现。</p>
