Practical streaming media was only made possible with advances in data compression due to the impractically high bandwidth requirements of uncompressed media. Raw digital audio encoded with pulse-code modulation (PCM) requires a bandwidth of 1.4 Mbit/s for uncompressed CD audio, while raw digital video requires a bandwidth of 168 Mbit/s for SD video and over 1000 Mbit/s for FHD video.[15]
