Question: Consider a DASH system (as discussed in Section 2.6) for which there are N video versions (at N different rates and qualities) and N audio

Consider a DASH system (as discussed in Section 2.6) for which there are N video versions (at N different rates and qualities) and N audio versions (at N different rates and qualities). Suppose we want to allow the player to choose at any time any of the A’ video versions and any of the N audio versions.

a. If we create files so that the audio is mixed in with the video, so server sends only one media stream at given time. How many files will the server need to store (each a different URLY?

b. If the server instead sends the audio and video streams separately and has the client synchronize the steams, how many flies will the server need to store?
