Question: In a PSS session, what is the primary purpose of the client providing buffer feedback to the server regarding its buffering situation?
Option 1: To enable the server to prioritize media content rate over transmission rate.
Option 2: To allow the server to exclusively control the client's network resource allocation.
Option 3: To facilitate the server in adjusting its transmission schedule based on the client's geographical location.
Option 4: To help the server avoid buffer underflow/overflow, ensuring interrupt-free playback by adapting media quality or transmission rate.
Explanation: The primary purpose of client buffer feedback in a PSS session is to enable the server to monitor and respond to the client's buffering situation. This allows the server to make informed decisions about whether to increase, decrease, or maintain the current media quality or transmission rate, preventing buffer underflows (playback interruptions) and overflows (packet losses), ensuring a seamless viewing experience.
