Question: What framework does a device capability profile for Transparent end-to-end Packet-switched Streaming Service (PSS) follow, in addition to having its own PSS-specific vocabulary?
Option 1: Device Capability Framework (DCF)
Option 2: Composite Capabilities/Preference Profiles (CC/PP) framework
Option 3: User Agent Profile (UAProf) framework alone
Option 4: Streaming Media Device Profile (SMDP)
Explanation: The correct answer is Option 2 because, according to the provided context, a device capability profile for PSS follows the structure of the Composite Capabilities/Preference Profiles (CC/PP) framework, in conjunction with the CC/PP application UAProf and an additional PSS-specific vocabulary. This indicates that while UAProf is utilized, it is specifically within the overarching structure of the CC/PP framework.
