Question: In a PSS scenario, where a client supports capability exchange and has prior knowledge of retrieving an SDP file via HTTP, what is the recommended action regarding profile information in the GET request?
Option 1: Omit profile information to reduce overhead.
Option 2: Include profile information to allow the HTTP server to deliver an optimized SDP.
Option 3: Send profile information only if the client has previously received an unoptimized SDP.
Option 4: Use SP (Service Protocol) instead of HTTP for optimized SDP delivery.
Explanation: Including profile information in the GET request when retrieving an SDP with HTTP enables the server to provide an optimized SDP tailored to the client's capabilities, enhancing the streaming experience. This aligns with guidelines for capability exchange in PSS, emphasizing efficient use of resources and personalized content delivery.
