Question: In a 3GP file conforming to the 3GP Media Stream Recording Profile, where are SRTP protected media packets and their corresponding SRTCP packets typically stored?
Option 1: Both SRTP and SRTCP packets are stored in a single, combined reception hint track.
Option 2: SRTP packets are stored in OMA BCAST STKM tracks, while SRTCP packets are stored in SRTP reception hint tracks.
Option 3: SRTP packets are stored in SDP information tracks, with SRTCP packets stored separately in Protection Description tracks.
Option 4: SRTP packets are stored in SRTP reception hint tracks, and corresponding SRTCP packets are stored in SRTCP reception hint tracks.
Explanation: This is the correct storage configuration for SRTP protected media and its corresponding SRTCP packets in a 3GP file that adheres to the 3GP Media Stream Recording Profile. Storing them in separate, dedicated tracks allows for efficient management and playback of protected streams, maintaining the integrity and security of the streamed content during storage and playback.
