All the new digital link should be the same way, this include HDMI and all the other streaming data links. I designed USB, Firewire, RS232 and some other serial digital links, they all do the same thing, they ALWAYS do error check ( we called parity check). They are have protocode to error checking and request for resend. I never work with HDMI and those streaming data links in hifi, BUT I would expect nothing less.
Therefore, they all should behave the same, it's either perfect or nothing, just like you bounce the CD player and it cut off. Or even more common, if you watch movie on computer, they transmit data as a stream through your internet provider. If the link is weak, too many error, your picture will freeze, waiting for enough good data and the movie will continue. Somethings you see blocks of color on the screen and the picture all garbled up, that's when the data cannot keep up with the real time. It will never slightly degrade the picture or the sound, it's either perfect of freeze and complete blowout.
I hate to say this, audiophile or high end hifi is such a tiny tiny little field even though everyone listen to music and watch movie, most people are happy with low to mid fi. Hell, My second step son gave me the pair of Monitor Audio Silver speakers and bought a sound bar!!! There are very little research and very little effort putting into the high end stuff. Put it in another way, if an EE is that good, they move onto the more state of the art jobs where there is big money to be earned. I seriously question people even design high end electronics really are that good and really know what they are talking. There are just so many snake oil floating around that people have to be very careful. Like the super expensive CD player with all the shock absorber and all. Special pure copper cables or exotic metal cables, special connectors, power cords. They are what give the bad reputation. Unlike those RCA and speaker cables, USB, HDMI cables are big markets, everyone use them. Engineering effort is being put into it. They are RF design and there is no BS, they label the cable, like they specify USB 3 cables, they test them to spec and there is no if and buts about it.
Hell, even those RCA cables, how can you try to sell exotic cables, it's not even that critical. Just get those that are with bigger diameter cables and tight connectors, it's all good. Even as much as I make a big stink on speaker cables, I use copper clad aluminum core cheap speaker cables from ebay to make my custom cable. What the hell is pure copper or some other exotic cables for? All snake oil in my book. It's knowledge and design that make good products. And the sad part is most engineers are not even willing to look at this audiophile stuffs. There is NO JOBS in this field. The economy is so good that if I want a job now, I can find a good pay job in a day. But I tried to look for a power amp design job, NOTHING!!! There is no jobs and no money in this field, nobody even want to look at this field. Hell, I never even look at audio electronics in my 30 year career, there are so many more interesting and challenging jobs than audio. It's only now that I retired, and this is my crossword puzzle to keep my brain active. It's not that hard.
