    113113During this week, we decided to take a step back to understand what the values in the JPEG hex values meant. Once analyzing the hex files from the video, it was quickly discovered there were certain indicators present, being FFD8 and FFD9. FFD8 represented the start of frame while FFD9 represented the end of the frame, while everything inside containing the frame contents. Knowing this, we were then able to isolate specific frames via these indicators via a Python script.

    117117After this step, we were finally able to calculate latency. By comparing the frame data to the packet data, we could find what exact packet correlates to the frame. By using the timestamp of the packet, we can then be able to find the latency.
