Digital Audio Network Through Ethernet (DANTE) Level 1 Practice Exam

The bandwidth demands of compressed video flow are primarily influenced by video frame resolution. This factor determines the number of pixels that are processed and transmitted in a video signal, which in turn affects the amount of data being sent over the network. Higher resolutions mean more pixels per frame, leading to larger file sizes and, consequently, greater bandwidth requirements.

While other factors like frame rate, chroma sampling, and power supply methods can also play roles in the quality and performance of video, it is the resolution that fundamentally dictates the volume of data necessary to accurately transmit each frame of video. A higher resolution requires significantly more bandwidth to ensure smooth playback and maintain quality, especially in scenarios demanding real-time video transmission.

Frame rate affects how many frames are played per second, but without the context of resolution, it has a less direct impact on bandwidth. Chroma sampling relates to color information within each pixel and affects compression efficiency but does not independently determine the total data volume. The power supply method relates more to the technical implementation of equipment rather than the video data itself.
