Question: In a Transparent end-to-end Packet-switched Streaming Service (PSS) scenario, when performing a partial successful Content Switch with an available Session Description Protocol (SDP), what is the primary reason for the client to initially switch the content before adding a new media component?
Option 1: To probe the server features again for the new media component.
Option 2: To receive the new data as quickly as possible, prioritizing stream continuity.
Option 3: To negotiate a new codec for the existing media components.
Option 4: To update the Quality of Service (QoS) parameters for the entire session.
Explanation: In PSS, minimizing latency and ensuring continuous streaming are crucial. By initially switching the content without adding the new media component, the client prioritizes receiving the new stream data as quickly as possible, maintaining stream continuity. The addition of the new media component follows, which might involve additional setup or negotiation but doesn't delay the primary content switch, thus ensuring a smoother user experience.
