Sky Sports fans in uproar after spotting ‘GHOST’ behind Jamie Carragher and Phil Neville | TV & Radio | Showbiz & TV | Daily Express

A recent clip, viewed by millions during the broadcast.

A few items of note:

 

-the ghost appears to be using a relatively modern lawnmower.  Whilst this fact has no bearing on the possibility of it being a ghost, it does narrow the time frame somewhat so that we are at least looking at a ghost image originating in the last 30-40 years.

-it is important to note the digital compression used by Sky TV for their broadcasts.  Anyone who has watched a live event broadcast by Sky will note the pixelation which occurs as the image moves and changes rapidly.  This pixelation is the result  of the compression codec which reduces the volume of data in an image.  The compression is achieved by only encoding the aspects of the image which change significantly, with the rest being rendered from the previous frame.  As a result of the compression, pixelation, blurring and ghosting are all common faults in the decoded image.  The truth is, most of the time these are not noticed as the attention is focused upon the main action on the screen.  If you watch the grass rather than the sport during a football or rugby game, then you will notice just how often these errors occur.

Was it a ghost?  It may have been, but it may also have been the result of the compression not rendering the groundsman.

 

 

SKY SPORTS viewers sent Twitter into meltdown after they caught sight of a rather eery figure behind Jamie Carragher and Phil Neville earlier this week.
