                 <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>

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. In this scenario, fast video rendering and high image quality are crucial. The SDK implements several performance optimizations, including automatically enabling accelerated audio and video frame rendering to minimize first-frame latency (no need to call <xref keyref="enableInstantMediaRendering"/>), and B-frame encoding to achieve better image quality and bandwidth efficiency. The SDK also provides enhanced video quality and smooth playback, even in poor network conditions or on lower-end devices.</p>
