Which one is better for HD 8PSK?

There were 14 HD services per CONUS transponder (8PSK 2/3 / HD Lite 1440x1080) and it overcompresses the bandwidth of its video streams which leads to a hint of marcoblocking. Some DISH customers were concerned about their HD quality, while AT&T|DirecTV had better picture. Back in 2008, there were 6 HD services per transponder, then 8 were moved/added in 2018. Having 14 per transponder would be such a sin or it could be the uplink centers who wouldn't do the maintenance for years.

There were 2 8PSK options that can reduce HD and 4K quality.
  • 8PSK 3/4 = 48 Mbps
  • 8PSK 5/6 = 54 Mbps

Reduce the quality ? - no problem.

Make it better ? There is alot of balancing act that goes into it - lower the FEC, at the cost of more uncorrected errors. There is alot of math going into this.

Throughout their existence as a satellite providers, both DirectTV and Dish have constantly been upgrading their MPEG encoders as technology gets better.

Changing from 8PSK 2/3 to 3/4 or 5/6 increases bandwidth. It does NOT reduce HD/4K quality. What it does is reduce the margin for rain fade (i.e. rain fade will happen sooner than it does at 2/3)
