Question: What is the primary purpose of capability exchange in the Transparent end-to-end Packet-switched Streaming Service (PSS), as per 3GPP standards?
Option 1: To ensure backward compatibility with non-PSS devices
Option 2: To enhance security protocols for content transmission
Option 3: To optimize network bandwidth usage during peak hours
Option 4: To enable PSS servers to provide device-tailored content and facilitate smooth transitions between different PSS releases
Explanation: Capability exchange is crucial in PSS for two main reasons: Device Adaptability, allowing PSS servers to adapt content to specific device capabilities for an optimal user experience, and Release Compatibility, facilitating seamless transitions between different PSS releases, maintaining service continuity and reducing potential disruptions.
