Level 1
No Transcoding

Transcoded files
fragmented files

Encryption
Quality Switching
Video Seeking
Live Video
Content Delivery Networks
Seg1 Seg2 Seg3

3GB video files
unfortunate
- bandwidth isn't free
- cpu isn't free
- storage isn't free
- encryption isn't free
Level 3
Two stage Transcoding
Seg1 Seg2
init
encrypted
Stage 1
Stage 2
Cons
- worse streaming latency
- higher costs per stream
- worse reliability
- more susceptible to attack
- Apple sucks
Pros
- lower storage costs
- lower cpu costs
- higher transcoding througput
Future
- drop safari support
- faster video startup
- more cpus -> faster transcodes
