Which one is better for HD 8PSK?

Discussion in 'DISH™ High Definition Discussion' started by GoLongAndChopChop881, Sep 25, 2018.

Do you think if DISH can reduce HD quality?

    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

    Your question is poorly worded. DISH can reduce the quality without even trying.

    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.

    Better for the PROVIDERS !
    not for us, customers :(

    Least common denominator - Dish and Direct keep their PQ just high enough to satisfy the masses, videophiles don't count.

    Customers who get hung up on numbers need to make a choice. Do they want high bitrates (higher than needed to deliver the content clearly) or high channel counts (carrying channels they will never watch). High channel count seems to be the winner with the more people whining that their favorite channel is available from the originator in HD but not carried in HD than complaining about perceived PQ. When people need a number to say the PQ is bad I wonder if they can actually see ad PQ with their eyes.

    DISH HD started with one or two MPEG2 channels per QPSK transponder. Now they have MPEG4 (or better) encoding on 8PSK channels. I have seen worse PQ on the early "6 channel per transponder" 8PSK pairing than I have seen recently. I agree with scooper that the encoding has improved ... and since the number of HD channels has risen without me noticing any lowering in PQ perhaps DISH is doing OK.

    customers "hang" on PQ !
    macro blocking, mosquito noise, banging, etc. are the current HD, if it good for your taste, don't spread it as providers do

    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)

    I kinda say that I was useless to say that wordless thread, but I just want to know why everything is getting worse. You guys were right.
