Question: What triggers an authorized MCVideo client to utilize MCVideo adaptation during an ongoing MCVideo communication session?
Option 1: Changes in network conditions, such as packet loss or packet delay.
Option 2: User Equipment (UE) hardware upgrades or software updates.
Option 3: Switching between different MCVideo service providers.
Option 4: Scheduled maintenance of the cellular network infrastructure.
Explanation: MCVideo adaptation is a feature designed to ensure seamless video communication by adjusting parameters (e.g., codec, resolution) in response to varying network conditions. The primary trigger for this adaptation is the detection of changes in network performance, such as increased packet loss or packet delay, which could impair video quality. This dynamic adjustment helps maintain optimal video transmission under fluctuating network conditions.
