Is there a way to manually add a digital subchannel thats not on the EPG? [Archive] - SageTV Community

  • . if the station is WKABCDT3 then be sure to use that call sign; this is how the subchannel is derived) From rule #1 the frequency to tune to is determined (the UHF channel).
  • . if the station is WKABCDT3 then be sure to use that call sign; this is how the subchannel is derived) ........
  • . I guess each is a different subchannel.
  • . The channel-channel-subchannel syntax works, but now you are advising against using it.
  • . If we are not to use this syntax because of an unknown efffect, how are we supposed to remap epg data to the correct subchannel if we can not differentiate them? _ MSI NX6600GT VIVO, Overlay - PVR 350 - PVR 250 - DVICO Fustion5 Gold USB - GA-K8N Pro, Athlon64 3200+ - 1Gb ram - XP SP2 - 750 gig - 37" Westinghouse LCD 1080P Humanzee # 02-09-2006, 09:02 PM New Member Join Date: Feb 2006 Posts: 4 This might explain 4 of the 5 channels that I can't tune Quote: Originally Posted by Narflex 2.

  • . A control method in a digital broadcast receiver for receiving a broadcast by specifying a main channel indicating a broadcast station and subchannels indicating broadcast programs, comprising the steps of: detecting the number of subchannels contained in a received main channel; and switching to a subchannel with the minimum number when the number of subchannels changes.

A control method in a digital broadcast receiver for receiving a broadcast by specifying a main channel indicating a broadcast station and subchannels indicating broadcast programs, comprising the steps of: detecting the numbers of the subchannels contained in a received main channel; and switching to a subchannel with the minimum number of the residual subchannels when the numbers of the subchannels received run out.
  • . A control method as defined in claim 2, wherein the numbers of the received main channel and the subchannel are outputted in the case of switching to the subchannel with the minimum number.



    simulcast: Definition and Much More From Answers.com
  • . On systems, analog-digital simulcasting (ADS) means that analog channels are duplicated as digital subchannels.
  • . Digital tuners are programmed to use the digital subchannel instead of the analog.

  • . From posts on various A/V and TiVo community forums, I was able to discern that the HTL-HD would automatically default the digital subchannel to 1, and that it would provide simultaneous high-definition and standard-definition output.

  • . Please scroll on down to the end, where the summary of the run is output: that's the part we use to make our $HOME/.azap/channels.conf file, as it contains the PIDs for the audio and video subchannels.
  • . They correspond to the audio and video PIDs for the two "stations" (actually referred to as virtual channels, or VCs in the ATSC spec) being transmitted with the 207000000 frequency, as follows: KNTV-HD:207000000:8VSB:65:68:4 NBC Wea:207000000:8VSB:81:84:5 The 4 and 5 in the last column at the end are the subchannel numbers, which can be selected using the mplayer option -trprog .
  • . E.g., to play subchannel 4, use: mplayer -tsprog 4 -ac hwac3 /dev/dvb/adapter0/dvr0 In the avsforum, the by JarginAU is well worth checking out, as it provides additional insight to using the DVB tools.
  • . Compiling xine-hd The only "gotcha" with plain xine is that you can't select the subchannel in the way mplayer can (using its -tsprog flag).
  • . The pcHDTV folks provide a patched version of xine called "xine-hd" which can select the subchannel using the "-C" option, e.g.: xine -C 52.4 $HOME/test.mpg The download provided by pcHDTV hasn't yet been patched to compile with gcc4, nor for ATSC DVB support (yet), so, if your system is using gcc4 by default, it's easiest to just compile xine-hd using gcc3 instead.

  • . Digital on 5 offers 4 subchannels: 49-1, 49-2, 49-3, and 49-4.
  • . KTXH digital subchannel is 19-1, not -2.
  • . There are 4 subchannels on digital channel 24: 14-1, 14-2, 14-3, and 14-4.
  • . KRIV digital subchannel is 26-1.
  • . KHWB digital subchannels are 39-1 and 39-2.
  • . KXLN digital subchannels are 45-1 (SD) and 45-2 (no data transmitted) KTMD analog channel is 47.
  • . The digital subchannel is 48-1.
  • . KAZH digital subchannel is 57-1.


    Multichannel Video Transmission
  • . (See for details.) The coder also contains a time-division multiplexer, called a high level mux, which creates a digital subchannel that is time-division multiplexed with the PCM video data.
  • . The video decoder also contains a high level demux, which separates the subchannel and sends it to a low level demux.

  • . 13 subchannels) Gordon L.
  • . If you didn't mention any subchannels, I assume it's not digital where you are.
  • . I get 2 subchannels on this one all the time.
  • . I've only seen 3 subchannels on this one.
  • . If I didn't mention subchannels, I get only one digital subchannel.

  • . Tidbits: All 6 KQED subchannels would appear in the 942 guide but at the moment, only one of them would have show info.
  • . That one would just match whatever is on the analog channel, even it the digital subchannel wasn't really airing the same content as the analog channel.
  • . Here in Sacto, there is only a single Digital subchannel for a station on Comcast.
  • . That means only one of the 4 PBS (KVIE) digital subchannels.
  • . That might mean only one of the 6 digital subchannels KQED sends on digital OTA is available with Comcast.


    TECHNOLOGY CORNER
  • . The BTSC stereo system is an adaptation with embellishment of the multiplex stereo system used on FM radio in the U.S., in which the main audio channel is modulated with the sum of the left and right stereo channels, and the difference between the left and right channels amplitude modulates a double-sideband suppressed carrier subchannel or subcarrier.
  • . This addition effectively cancels the signal-to-noise penalty contributed by the L-R subchannel.


    IEEE Spectrum Online: Feature Article
  • . The broadcaster divides the TV channel (8 MHz in Europe) into several thousand narrow subchannels.
  • . The digital code (usually flowing at 24 Mb/s) is split into that many streams, with one stream sent on each subchannel.
  • . So each subchannel carries relatively fewer bits of code per unit time--a few kilobits per second--spaced relatively widely apart in time.
  • . ISDB uses a modified form of COFDM, with several thousand subchannels in 13 groups carrying the TV signal in different resolutions.

  • . come diamine si creano i subchannels su roSe? :P Digital Snake® 07-07-2005, 14:20 Beh basta configurare l'opzione apposita...
  • . il fatto è che neanche io ho mai capito che cavolo sono effettivamente questi subchannels e a cosa servono Syberius 07-07-2005, 15:19 Ok, ma l'opzione apposita...
  • . :thx Syberius 09-07-2005, 12:55 Sei un grande Digi, grazie mille ;) x5494 15-07-2005, 15:59 Ho notato che i subchannels si vedono senza topic in lista..
  • . come si potrebbero far visualizzare? :rolleyes: :confused: Digital Snake® 15-07-2005, 16:08 Non ho modo di provare adesso..ma teoricamente si dovrebbe entrare sul subchannel a cui manca il topic..e metterglielo semplicemente col comando a riga /topic Syberius 15-07-2005, 16:14 Confermo pienamente quanto detto da Digital: una volta entrati nel canale si possono usare tutti i comandi del roboserv, e quindi settare topic, password di ingresso, ecc...
  • . acabinet 15-07-2005, 21:35 ragazzi ho provato roboserv ma ho un problemino appena lo faccio andare online e tento di entrarci da errore e si kiude il server P.S.:per entrare faccio nomemiachat_127.0.0.1:protalibera Digital Snake® 16-07-2005, 09:25 Che errore ti da di preciso? Come mai usi quell'indirizzo? Hai un router? x5494 16-07-2005, 14:39 Devo dire la verità io con questo server mi ci trovo piuttosto male :( :crii ma con wcs o fx mi pare che più di un subchannel non si possa fare..

  • . AES/EBU digital audio bus (AES3) is a digital audio transmission standard that is based on a synchronous, self-clocking RS-422A compatible physical layer on top of which stereo digital audio and associated subchannel data is transmitted.
