The PS4 isn't using encoding to display the image on Vita, rather a direct stream at Vita's native resolution.

video data will always be encoded before they are send, as raw video data is huge, even at PSV's native resolution - simply encoding it to h.264 can made it 1/10th of the data while keeping the same quality


Maybe I'm reading it wrong and they are just referring to the video files etc. Well however they do it they listed the latency speed of the stream and it is a welcomed improvement over the PS3's.

Nah, you are just a bit confused about things here. What the PS4 essentially sends to the PSV is a video of what it is doing at that time. Sending that as raw data is essentially sending 30/60 bitmap pictures per second, which is a huge amount of data. A 960x544 (PSV native resolution) bmp is 1.5MB, so an uncompressed video at 30 fps is 45MB per second (360mb/s) (or twice that for 60fps video) - more than even most wlan connections can transport. That's why the data is encoded/compressed before it is send, as that way you can have virtually the same quality at a small fraction of that size.
