Source Content

We'll be packaging the original content for playback and delivery. The source content consists of a combination audio tracks and video tracks. The video is available in different bitrates (for adaptive streaming) and the audio has been encoded using a variety of audio codecs to support the best quality audio for the different devices.

The following is a list of all the files that we use as input for the packaging. Source content:

audio_aac-lc.mp4	AAC-LC (Advanced Audio Codec - Low Complexity) audio track
audio_he-aac.mp4	HE-AAC (High Efficiency AAC) audio track
audio_dts-express.mp4	DTS Express 5.1 audio track
audio_ac3.mp4	AC-3 (Dolby Digital) audio track
