Re: Nextbox 4K PVR might look best with 1080i output!

Anyone know if the TMN/HBO On Demand content is 1080p? Or is it just the Rogers On Demand content (ch100) that's 1080p?

Re: Nextbox 4K PVR might look best with 1080i output!

So I was playing around with the resolution setting on my NB3 since I hadn't touched it in a long time. Looks like they fixed the 1080p setting. 1080p now looks better than 1080i. I have to believe the 4K boxes are the same.

I've had my Nextbox 3.0 outputting 1080p for a few months now. I also notice it outputs better at 1080p vs 1080i.
I can't wait for Rogers to launch the X1 platform next year, hopefully they change the compression scheme currently in use to something that offers higher quality. Remember X1 isn't true IPTV, it's a hybrid setup.

My nextbox3 died. Went to Rogers store for replacement. No 3's available so they gave me a 4k box with the 4k feature deactivated. The picture seems not as sharp as nextbox3 in 1080p. Slightly fuzzy. I think the 4 may be worse than the 3 for non-4k. Considering returning it for a 3. Anybody else experience this?

Re: Nextbox 4K PVR might look best with 1080i output!

@jeff7y :  On another forum, people who have Bell and 4K boxes complained of a similar problem, however, Bell sends all HD channels out as 720P, so when they changed their boxes to 720P, they had good quality on the HD channels.

 

Have you tried 1080i instead of 1080P?  It's possible that disabling 4K has an impact, but I've never heard of that.  I've heard of lots of people getting 4K boxes, but not of them being "hobbled".  If you have a 4K TV have you tried the 4K setting?

 

Also, are you using the same input on the TV as before? Sometimes inputs are different and TV inputs always require optimization (calibration). Different devices can have different outputs and different inputs on the TV can have different settings - for example, contrast, brightness, tint, colour, sharpness, etc.

@jeff7y

Have you tried calling into other Rogers stores to get the Nextbox 3?

Also as @57 mentioned, try setting the box to output 1080i

Does Rogers actually send out any content at 1080p or is it all just 1080i and 720p, depending on the channel?  I don't think 1080p is part of the ATSC standard, is it?  That may not technically matter since this isn't OTA but it likely is important for setting standards.

Some On-demand programming may be 1080p, however, all of the HD channels are 720P or 1080i. See the following FAQ.

Re: Nextbox 4K PVR might look best with 1080i output!

I recently went from a 8642pvr which is Nextbox 2.0 and skipped the 3.0 and went straight to the 4k pvr. Now that I have it set to 1080p I think it looks much better. I haven't picked up the 4k tv yet but soon. The speed alone compared the NB 2.0 is worth it.

Your correct, I think what You where saying, that video should always be watched in the recorded format. However You don’t have the knowledge to realize allot of what You said is wrong

Resolution is not a big but changing timing with deleting or inserting frames cause ALLOT of video artifacts like jitter

*THERE IS NO ROUNDED UP OR DOWN* the reason the NTSC chose 29.97 Hz for *color* is because B/W TV’s where using PLL & Hetro at 30 Hz and the middle stages would still lock on with added chromo (color) they needed a colour burst signal/sync for the color carrier at 29.97. There IS NO ROUNDING UP OR DOWN, it’s based on always a very accurate TCXO (temperature compensated crystal oscillator) for transmission and a phase locked loop on the receiver. Now it gets millisecond corrects from often GPS but for Canada Wide main transmitters atomic clocks for the CBC - Because it was the doomsday network for Canada and part of the DND/Defence Network with secure data communications (closed captioning x allot I dunno, even if I did - I dunno)

Also for the last 30 years, and totally in the last fifteen Years (with exceptions) professional movies and TV no longer have a DI-Digital Intermediate/telechine

Instead it’s shot at a multiple of the ‘film’ (rarely do theatres Actually use film except for niche audiences with film not digitized yet) DVD and 30/60p. DVB-T is already compressed and has the frame rate

So normally You shoot in digital with a frame rate that is divisible for DVD/UHD-3840-2160/HD-1920-1080

Don’t forget as noted above 4K is not actually 4k*Anything-Good marketing good for manufactures bad for US


Things get complicated working to try to support old equipment to its dying breath and still provide better viewer experiences


So it’s often recorded with $50,000 Professional variable frame rate recording (excluding Len/s that’s around a few hundred thousand more) ‘Varicam’ or not trade marked look alikes

Sony used to be king with Beta, BetaMax and Digital Beta however it was all closed and with the rapid changes executives managers and techs all together got skiddish about being “Locked In”

But Panasonic released its DVC, DVCPRO, DVCPRO(25/50) then HDDVCPRO all using open license Rice *Lossless Encoding/Compression*

The problem solver with film versus video ‘is to shoot it’ from the ‘big screen’ is a bit crazy. It will add flicker and aliasing. It is a 1980/60 “cutting edge flicker” but I may of misunderstood You

The reason You can’t plug in a USB storage device/key in is because of the media rights, which is a Actually close to a huge bookshelf on its own !!

Everybody has to remember the quantization errors (Nyquest’s law) aliases and most of all frame rate changes which are not evenly multiplied or decided *EVENLY* cause allot of ‘artifacts’/distortion & a bad experience for the viewer
