@pranava 91....10101010's are used by receiver to synchronize its clock.While 11 the last two bits of 8th byte indicates SOF(start of frame).

I was wondering why do have 8 bytes long preamble ? Like we have explanation why there should be a minimum frame size, what is reason behind having such long preamble

[pranava91]

@abh03533 Preamble size is kept a 8 bytes for clock synchronization. First 7 bytes are 10101010 and the 8 byte is 10101011. I dont know the reason behind choosing these sequence :)

Why add this to YouTube at all. There is no sound (H.264 video) and the image quality is so poor.
