Final answer:
The correct answer is option C. The number of clock leaders elected depends on the synchronization requirements of the network, with separate clock leaders for each video frame rate and audio sample rate.
Step-by-step explanation:
In a network with audio and video devices providing content at different resolutions and sample rates, the number of clock leaders elected depends on the synchronization requirements of the network. A clock leader is responsible for ensuring that all devices in the network are synchronized and can play the content smoothly.
In this case, the network has devices providing content at 4K/60, 1080p/60, 96KHz, and 48KHz. To ensure smooth playback, separate clock leaders would be elected for each video frame rate (4K/60 and 1080p/60) and each audio sample rate (96KHz and 48KHz). Therefore, the correct answer is option C. 4 - one for each video frame rate and sample rate.
If a network has audio and video devices providing content at 4K/60, 1080p/60, 96KHz and 48KHz, the number of clock leaders elected would be B. 2 - one for video, one for audio. This is because video and audio streams generally require separate synchronization due to their distinct nature and processing requirements. Typically, a video clock leader would manage video frame rates (4K/60 and 1080p/60), and an audio clock leader would manage audio sample rates (96KHz and 48KHz).
