Question: In a DASH (Dynamic Adaptive Streaming over HTTP) system, if a segmenter loses synchronization due to issues like power outage or signal losses, what is the preferred approach to address this issue while maintaining a conforming media stream?
Option 1: Utilize Early Terminated Periods for signaling no more media is present, prompting clients to await a new period.
Option 2: Implement a buffer overflow strategy to store excess data for seamless playback once synchronization is regained.
Option 3: Automatically switch to a lower quality stream to reduce the likelihood of future synchronization losses.
Option 4: Insert dummy content using a separate Period structure without modifying the standard, ensuring continuous segment generation.
Explanation: The correct approach is utilizing Early Terminated Periods for signaling synchronization loss and media outage. This method allows the server to communicate the issue to clients effectively, enabling them to take appropriate actions. While inserting dummy content is also a viable strategy, Early Terminated Periods are the more specific and technically appropriate choice for signaling such outages.
