microHD Development: Bug Reports and Firmware Fixes

[SatelliteAV]

Good catch on the Teletext ON. We will correct.

Teletext is often found on the Atlantic birds. On the west coast, we can only test with a TS stream.

Just a Friendly Reminder:

Please only post confirmed bugs and issues to this thread. I have moved several non-issues and discussions out of this thread in order to try and keep it readable and manageable.

Thanks!

Manual PID entry for audio/video signals without an SI stream doesn't work.

I manually added a signal to the receiver that I found but had no SI stream. All PIDS were unencrypted. I then changed scan mode from "NORMAL" to "PID" for that signal and punched in the values for video, audio, PCR and hit "OK". When the scan finished, there was a "no program found" error. My expectation was a new channel written to microhd memory using the video/audio/PCR values that I entered with not mattering if a SI steam existed or not.

If a service exists on a transponder that matches the manually entered PIDs, a channel is logged and listed. I wouldn't say that it is wrong, just different than your expectation.

OK I'll try to explain this one. I've been PM'ing Milelib about a bug he came across and hopefully he can add to it

I've noticed once in a while you will go to a channel and have signal but black screen. A great example is the test card on 85W (12195 H 3978). The only way to get it back is to rescan the transponder. Nothing changes PID wise but then it pops in.
Mikelib was mentioning using a detail scan to find the Florida channel. Here is part of the PM

I go back in to try and get the Florida channel again, so I do a detail blindscan, I set the V side to scan only from 12100 to 12200. I scan and get no channels found. I exit to check the channels and I have no video on any channels. Power the box on and off with the remote no channels. I check and I have good signal and quality on each of the H transponder, I do a preprogram transponder scan and all channel scan in, I exit out and I have good video on each channel.

then I got a 2nd one where I was able to duplicate it. He has the H side of 87W programmed in and working and he is doing a detail scan for Florida channel

I can relicate the problem every time now. With good video on the channels listed, I just have to do a detail blind scan on the V side and set the frequencys to make sure I will not scan anything in. After the notice no program found, I exit out and video is loss. I have to do a preprogram transponder scan to get the video back.

I was able to duplicate it using 12100-12200 as the frequency range. I know on the Manhattan sometimes if you stop a blind scan early it gives you no picture on channels logged too.

Is the polarity selection left as vertical after the scan? If so, then this satellite is now configured to only tune vertical. The channels will display if the satellite set-up is returned to auto.

Scanning the preprogrammed TP List returns the receiver to the default Auto.

nope. Back to auto. It shows signal quality on Horizontal polarities (up to 80 on LPB) but black screen
(if it was still on V the quality on the H side would be 0)

To come to a understanding, is it in the to-do list to add or fix the manual PID function of the microHD when a SI doesn't exist or when audio/video is in a signal but not listed in the SI stream -- or was your response addressing this situation and not the other one I had in my original post?

I suppose I could use the channel editor to add the service I'm analyzing (and other ones I come across that have audio/video unencrypted PIDS but there is no SI stream or not listed in the SI stream) but I'd rather try to do it from the receiver OSD and remote for convenience.

Drop me a PM and we will discuss. Not completely sure what is needed. If it possible to modify to meet your request we will address.

Scanning the preprogrammed TP List returns the receiver to the default Auto.

Brian,

If I remember correctly I would have to manually set the preprogrammed TP list to auto as I alreadly scanned once with the polarity set to V and it did not scan the H polarity TPs.

I would think that no matter what I do on the scan menu once I return to main screen I should see video on the channels previously scanned in no matter the polarity.

Are you are saying that once I leave the scan page, it is up to me to set the polarity back to auto, in order to get video back on the previously scanned channels???

When you select a polarity to scan (only V as example) it "sticks" until you change it. The issue is that I left it at "auto" and was able to duplicate it (and did it again this morning on 85W...I purposely scanned 11700-12100 which left out the 12195 TP. Scanned nothing and when I went hack to the test card I got blank screen but 72 quality.

If the receiver stayed on V you wouldnt have signal on the H transponders

When this had happened to me in the past I changed the polarity back to the default auto mode and the channel video and audio returned.
Will try to duplicate and report.

When I rename a transponder, such as Azteca 13 on G25, a rescan of the satellite (for the purpose of searching for feeds) returns the name to "Service 2." I'm not sure if this is a true bug, but it would be great if the channel memory routine could check to see if a channel is already registered and, if so, leave the name alone.

Also, has anyone noticed a problem with the audio and video being slightly out of sync? I originally thought it was a problem with some of the low-budget channels on 97W, but noticed the same on LPD HD and, currently, on Azteca. Recording of the channel reveals the problem is with the receiver, not something in the monitor.

Not a bug, just an operational preference. The request has been previously made to save Service Names and not overwrite (not transponders) and we will may be able to incorporate in a future version. This would also eliminate the renaming of services if the uplinker changes the client or the multiuse frequency for the ENG trucks. Not sure if this is desirable or not...

Haven't noticed. Curious how recording the channel determines if the sync issue is with the STB or monitor?

On LPB-HD I notice Gwen Ifill will be in sync, but her remote guests are way off. I can't blame that one on the stb. Anyone else seeing sync issues?

 

[Magic Static]

I experienced a BIG audio sync problem after watching movies stored on the USB drive and going back to TV. Had to restart the unit to correct this. I found out this was related to the drive I had plugged into the USB port. The drive I'm using now does not give me that issue.

that was mentioned originally in the review

Channel editing is very easy to do. Go into the TV channel (or radio if you need to work on those) and use the color buttons to edit a channel name, move them around or remove. One thing I wish the MicroHD had was a way to remove all channels from a transponder. My GeosatPro 200 has that option. I can remove channels one by one, per transponder or per satellite. Also I noticed that if you rename a channel and do a blind scan at another time it overwrites the edited name. As we all know very few of the PBS channels actually have a name attached. Most are “TV3”, “TV4” etc. So I renamed TV3 & TV4 as PBS HD EAST and PBS HD WEST. Well when I redid a blind scan later when it found 12140 V 30000 (where they are located) it renamed them back to TV3 & TV4.

A selectable "lock" for each memory position would allow some to remain unchanged but others to be preprogrammed. I'm not sure how much work that would be though.

I should have explained. If I playback the recorded file on my PC the delay is still there. It's in the video file that has been recorded, so was present when the file was recorded to disc.

Not that simple. Is the unit set up to record PS or TS? The unit does not record a decoded and AV combined file. The PC playback showing the same error would point to problem with the mux rather than decoding issue with the microHD.

It's recording TS. I haven't played around with the recorder set-up menus since I found out the defaults were compatible with the PC.

I'll play around with it a bit more and see if there is a pattern to when I notice the problem. Is there any other trouble shooting I can do?

 

[SatelliteAV]

Transport Streams consists of Video (vpid), Audio (apid) and Program Clock Reference (pcr). The microHD does not combine or modify these pids. If the TS recording is not in sync when played on another device, the problem is with the the data. If the sync issue only occurs with the microHD, but plays back correctly on other devices, then the issue could be with the microHD.
