Encoding & Profiles • Encoding profiles for each service – Configuring different bitrates for adaptive bitrate – Distinguish various encoding parameters for playback optimization on different devices Audio only, bitrate 64kps H264, 480x300, bitrate 150kps H264, 480x300, bitrate 240kps
Original video audio stream
H264, 480x300, bitrate 440kps H264, 640x480, bitrate 640kps
H264, 640x360, bitrate 1240kps
Any device Adaptive bitrate Client device selects according to available bandwidth
