[mythtv-users] Cannot change channel and low FPS problems
Hello, Could someone please explan what is what of: * Channel ID * Channel number * Channel callsign This is what it looks like in my database: mysql use mythconverg; mysql select chanid, channum, freqid, sourceid, callsign, name from channel; ++-++--+--+---+ | chanid | channum | freqid | sourceid | callsign | name | ++-++--+--+---+ | 1000 | SE11||1 | 1000 | Kanal 5 | | 1001 | E5 ||1 | 1001 | Svt 1 | | 1002 | E7 ||1 | 1002 | Svt 2 | | 1003 | E6 ||1 | 1003 | TV4 | | 1004 | 57 ||1 | 1004 | TV4 Plus | | 1005 | E11 ||1 | 1005 | TV3 | | 1006 | E8 ||1 | 1006 | ZTV | | 1007 | E10 ||1 | 1007 | Discovery Mix | | 1008 | SE17||1 | 1008 | Eurosport | | 1009 | SE16||1 | 1009 | MTV Nordic| ++-++--+--+---+ 10 rows in set (0.00 sec) 1001...1009 has been autogenerated from somewhere I think, maybe tv_grab_se_swedb or such. I don't know it is correct and I am afraid to fuck something up if I change those numbers. I'd like to map channels as one would do with a plain ol' TV (National Channel 1 - Button 1 etc). What should I change? I have probems chaning channels in myth. Picture is displayed OK and I can use ivtv:s ptune.pl -c SE16 to watch MTV. If I try to change channel in myth, picture freezes for a second or two and then the same channel is still displayed. Mythfilldatabase is OK i think. EPG info an such look good. Maybe it has something to do with the above channel setup? Or maybe MythTV relies on some tuner script that it can't find? Or maybe it is because the freqid field in the database is empty? (What is this field for anyway?) My channel plan is PAL europe-west. There is another problem aswell. Picure is slow motion. Feels like it would be ~10 FPS or such. Strange. Playing video like mplayer /dev/video0 is all fine. Myth system specs: Gentoo 2.6.11-r6 kernel ivtv 0.3.4b mythtv from CVS grabbed 2005-05-04 CPU: Intel PIII 800Mhz TV-Card: WinTV PVR-150 (non-MCE) Graphics: NVidia FX5200 with nvidia binary driver 1.0.6629 Best regards, Rickard Borgmäster ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

(What is this field for anyway?) My channel plan is PAL europe-west. I had similar problems when I first tried setting up channels. Try running the mythbackend and frontend from seperate shells so you can see any errors being generated when you try to change the channel. Mine (from memory.it was a few months ago now) was caused by me having messed up adding some channels, so it basically couldn't find anything 'valid' to switch to. I could view the initial channel that MythTV started on, but when trying to change I got exactly what you describe. I'm using Europe-west for the channels as well. I'd have to check in my channels setup to see what I have in for the freqid, but I think I've put the channel number (i.e BBC1 is 29 or something similar - depending on what your signal source is). I'm currently getting the normal terrestrial channels directly off my cable TV's coax, tho the picture isn't all that fantastic (especially comparted to the 'real' cable channels). Hope this is helpful in some small way, cos it was starting to drive me nuts when I could see channel info, but not change to it ! ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

First, a channel and a station are not the same thing. A station is in a building with employees with lots of wire and equipment and usually has an antenna on top or on a nearby hill. A channel is a frequency or identifier that a TV set uses to select a signal on the wire from an antenna or cable. The same station may be available on two or more channels or from two or more video sources (over the air, cable, satellite, digital). The same channel (frequency) in another location may carry a different station's broadcasts. mysql select chanid, channum, freqid, sourceid, callsign, name from channel - where callsign = 'CNN' or callsign = 'HBO' or callsign = 'KVBC' - order by callsign; ++-++--+--++ | chanid | channum | freqid | sourceid | callsign | name | ++-++--+--++ | 1020 | 20 | 20 |1 | CNN | Cable News Network | | 2210 | 210 | 210|2 | HBO | Home Box Office| | 1003 | 3 | 3 |1 | KVBC | KVBC (NBC) | | 2003 | 3 | 3 |2 | KVBC | KVBC (NBC) | | 2123 | 123 | 123|2 | KVBC | KVBC (NBC) | ++-++--+--++ 4 rows in set (0.01 sec) Chanid distinguishes that 1003 and 2003 are the information for source 1 and 2 even though they are the same station on the same channel. Channum 123 is a different channel for KVBC and needs a different frequency to get the programming from the same station that is also on channel 3. Freqids for source one are sent to the tuner for the coax input. Source 2 is a digital cable box connected to s-video and the freqid is sent to an external script. Sourceid 1 is analog coax cable. 2 is from a digital settop box. The callsigns can be used in small spaces in the UI to identify the station such as the left column of the EPG or the middle column for Upcoming Recordings. However, it is also used by the scheduler for 'channel matching'. If I set a Channel record rule for The Apprentice (NBC) on 123, the scheduler sees that this is on KVBC and it could use chanid 1003, 2003, or 2123 to record this. More info on how and why it chooses which one to use can be found at: http://www.mythtv.org/docs/mythtv-HOWTO-11.html#ss11.7 The channel name has no function other than for display in the UI where there is room for a full station name like the information area at the bottom of the Set Priorities page. -- bjm ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I believe in your country this may be need the actual frequency values. Hopefully one of youir countrymen can let you know exactly how to fill these in. Without these, myth cannnot change channels for you. Thanks Bruce, Now I realize that I had mixed up channel number with frequency id. I've adjusted that now for my local feed (ComHem analogue): ++-++--+---+---+ | chanid | channum | freqid | sourceid | callsign | name | ++-++--+---+---+ | 1000 | 5 | SE11 |1 | Kanal 5 | Kanal 5 | | 1001 | 1 | E5 |1 | SVT1 | Svt 1 | | 1002 | 2 | E7 |1 | SVT2 | Svt 2 | | 1003 | 4 | E6 |1 | TV4 | TV4 | | 1004 | 8 | 57 |1 | TV4+ | TV4 Plus | | 1005 | 3 | E11|1 | TV3 | TV3 Sverige | | 1006 | 6 | E8 |1 | ZTV | ZTV | | 1007 | 9 | E10|1 | Discovery Mix | Discovery Mix | | 1008 | 10 | SE17 |1 | Eurosport | Eurosport | | 1009 | 7 | SE16 |1 | MTV | MTV Nordic| ++-++--+---+---+ And now changing channels work fine :-) Not as fast as I'd like to but still fine. I think I have got a better clue about what is what now. Thank you for that explanation. Now I just gotta find out why picture FPS is so low :-(( -- Rickard .--..--. .. | || | .-. | Rickard Borgmäster | | || |/ / | [EMAIL PROTECTED] | .-^ | .--. | | http://doktorn.sub.nu/ | ( o | ( () ) | |\ \ `' `-' `--' `--' `--' ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
