Synopsis and Themes

Identify

| # | Objective | Measurable Outcome | |---|-----------|--------------------| | 1 | the three most critical architectural changes introduced in Java 17 that impact streaming pipelines. | List and briefly explain each change. | | 2 | Explain how Adaptive Bitrate (ABR) algorithms have evolved in 2023 for UHD (4K/8K) delivery. | Compare at least two ABR strategies and cite performance metrics. | | 3 | Configure a Java‑based media server to support low‑latency live streaming using the Low‑Latency HLS (LL‑HLS) spec. | Demonstrate the required server‑side configuration lines. | | 4 | Apply the latest DRM (Widevine, PlayReady, FairPlay) integration patterns in a micro‑service architecture. | Sketch a high‑level component diagram with security boundaries. | | 5 | Assess compliance with the new EU “Digital Services Act” (DSA) provisions for video‑on‑demand platforms. | Summarize the three key compliance checkpoints. | | 6 | Troubleshoot common performance bottlenecks in transcoding pipelines using JFR (Java Flight Recorder). | Interpret a sample JFR snapshot and pinpoint the root cause. |

JMC

| Step | Action | |------|--------| | 1 | Enable JFR at startup: -XX:StartFlightRecording=duration=30m,filename=streaming.jfr | | 2 | Filter for jdk.CPULoad , jdk.GCPhasePause , jdk.SocketRead | | 3 | Export to (Java Mission Control) and identify top‑5 hot spots | | 4 | Apply targeted JVM flags ( -XX:MaxInlineLevel=15 , -XX:+UnlockExperimentalVMOptions , -XX:+UseZGC ) | | 5 | Re‑run benchmark (e.g., k6 or Gatling ) to validate improvement | DLDSS-015-EN-JAVHD-TODAY-0511202302-02-54 Min
