Artificial Intelligence (AI) is becoming increasingly important across various industries, including social media and gaming, healthcare, and transportation. AI refers to the process of incorporating human intelligence into machines, particularly computer systems. It differs from machine learning (ML), which is a training process for machines to make decisions, and deep learning (DL), a subset of ML that works similarly to the human brain in processing new information. AI can improve interactive streaming by detecting harmful content, enhancing video and voice quality, and personalizing user experiences. Social media platforms like Facebook are employing AI to remove and prevent harmful content before it's posted using image analysis techniques such as image classification, object detection, and image segmentation. ML is used by companies like YouTube and Netflix to optimize encoding parameters for videos, improving the quality of experience (QoE) for users while reducing costs. Agora uses AI in various ways, including its proprietary Software-Defined Real-Time Network™ (SD-RTN™) to manage routing of voice and video streams and Agora Super Resolution feature to enhance clarity and sharpness during interactive streams. AR stickers and filters, live voice features like 3D spatial audio, active speaker detection, and voice effects are some AI-powered engagement features that can be customized for different applications or platforms. In the future, AI is expected to continue shaping the interactive streaming space by enabling more immersive and engaging live streaming experiences.

This tutorial guides developers through building a live broadcasting web-app similar to Facebook Live and YouTube Live, using Agora's WebSDK. The app allows a single broadcaster to stream their video feed to multiple audience members. The architecture is similar to that of a communication web-app but with the added functionality of distinguishing between broadcasters and audience members. The tutorial includes instructions for setting up the HTML structure, designing the user interface, and implementing Javascript clients for both broadcasters and audiences. It also covers testing setup using XAMPP and ngrok to enable a secure HTTPS connection.

The article provides a step-by-step tutorial on how to test iOS Video SDKs under different network conditions using Apple's Network Link Conditioner. The tool allows developers to simulate adverse networking environments, such as packet degradation, and compare the performance of their codebases side-by-side. By enabling the Network Link Conditioner, developers can create custom profiles with varying levels of packet loss and latency, allowing them to test their SDKs in real-time. The article highlights the benefits of using Agora's SDK, which outperforms competing options like TokBox and Twilio under adverse network conditions.
