Please check at the DVB wiki + at https://linuxtv.org/wiki for more updated info. + + There's a section there specific for Avermedia boards at: + https://linuxtv.org/wiki/index.php/AVerMedia + + +Assumptions and Introduction +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +It is assumed that the reader understands the basic structure +of the Linux Kernel DVB drivers and the general principles of +Digital TV. + +One significant difference between Digital TV and Analogue TV +that the unwary (like myself) should consider is that, +although the component structure of budget DVB-T cards are +substantially similar to Analogue TV cards, they function in +substantially different ways. + +The purpose of an Analogue TV is to receive and display an +Analogue Television signal. An Analogue TV signal (otherwise +known as composite video) is an analogue encoding of a +sequence of image frames (25 per second) rasterised using an +interlacing technique. Interlacing takes two fields to +represent one frame. Computers today are at their best when +dealing with digital signals, not analogue signals and a +composite video signal is about as far removed from a digital +data stream as you can get. Therefore, an Analogue TV card for +a PC has the following purpose: + +* Tune the receiver to receive a broadcast signal +* demodulate the broadcast signal +* demultiplex the analogue video signal and analogue audio + signal. **NOTE:** some countries employ a digital audio signal + embedded within the modulated composite analogue signal - + NICAM.) +* digitize the analogue video signal and make the resulting + datastream available to the data bus. + +The digital datastream from an Analogue TV card is generated +by circuitry on the card and is often presented uncompressed. +For a PAL TV signal encoded at a resolution of 768x576 24-bit +color pixels over 25 frames per second - a fair amount of data +is generated and must be processed by the PC before it can be +displayed on the video monitor screen. Some Analogue TV cards +for PCs have onboard MPEG2 encoders which permit the raw +digital data stream to be presented to the PC in an encoded +and compressed form - similar to the form that is used in +Digital TV. + +The purpose of a simple budget digital TV card (DVB-T,C or S) +is to simply: + +* Tune the received to receive a broadcast signal. +* Extract the encoded digital datastream from the broadcast + signal. +* Make the encoded digital datastream (MPEG2) available to + the data bus. + +The significant difference between the two is that the tuner +on the analogue TV card spits out an Analogue signal, whereas +the tuner on the digital TV card spits out a compressed +encoded digital datastream. As the signal is already +digitised, it is trivial to pass this datastream to the PC +databus with minimal additional processing and then extract +the digital video and audio datastreams passing them to the +appropriate software or hardware for decoding and viewing. + +The Avermedia DVB-T +~~~~~~~~~~~~~~~~~~~ + +The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs: + +* RF Tuner Input +* Composite Video Input (RCA Jack) +* SVIDEO Input (Mini-DIN) + +The RF Tuner Input is the input to the tuner module of the +card. The Tuner is otherwise known as the "Frontend" . The +Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely +post to the linux-dvb mailing list ascertained that the +Microtune 7202D is supported by the sp887x driver which is +found in the dvb-hw CVS module. + +The DVB-T card is based around the BT878 chip which is a very +common multimedia bridge and often found on Analogue TV cards. +There is no on-board MPEG2 decoder, which means that all MPEG2 +decoding must be done in software, or if you have one, on an +MPEG2 hardware decoding card or chipset. + + +Getting the card going +~~~~~~~~~~~~~~~~~~~~~~ + +In order to fire up the card, it is necessary to load a number +of modules from the DVB driver set. Prior to this it will have +been necessary to download these drivers from the linuxtv CVS +server and compile them successfully. + +Depending on the card's feature set, the Device Driver API for +DVB under Linux will expose some of the following device files +in the /dev tree: + +* /dev/dvb/adapter0/audio0 +* /dev/dvb/adapter0/ca0 +* /dev/dvb/adapter0/demux0 +* /dev/dvb/adapter0/dvr0 +* /dev/dvb/adapter0/frontend0 +* /dev/dvb/adapter0/net0 +* /dev/dvb/adapter0/osd0 +* /dev/dvb/adapter0/video0 + +The primary device nodes that we are interested in (at this +stage) for the Avermedia DVB-T are: + +* /dev/dvb/adapter0/dvr0 +* /dev/dvb/adapter0/frontend0 + +The dvr0 device node is used to read the MPEG2 Data Stream and +the frontend0 node is used to tune the frontend tuner module. + +At this stage, it has not been able to ascertain the +functionality of the remaining device nodes in respect of the +Avermedia DVBT. However, full functionality in respect of +tuning, receiving and supplying the MPEG2 data stream is +possible with the currently available versions of the driver. +It may be possible that additional functionality is available +from the card (i.e. viewing the additional analogue inputs +that the card presents), but this has not been tested yet. If +I get around to this, I'll update the document with whatever I +find. + +To power up the card, load the following modules in the +following order: + +* modprobe bttv (normally loaded automatically) +* modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules) + +Insertion of these modules into the running kernel will +activate the appropriate DVB device nodes. It is then possible +to start accessing the card with utilities such as scan, tzap, +dvbstream etc. + +The frontend module sp887x.o, requires an external firmware. +/*(DEBLOBBED)*/ + +Receiving DVB-T in Australia +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +I have no experience of DVB-T in other countries other than +Australia, so I will attempt to explain how it works here in +Melbourne and how this affects the configuration of the DVB-T +card. + +The Digital Broadcasting Australia website has a Reception +locatortool which provides information on transponder channels +and frequencies. My local transmitter happens to be Mount +Dandenong. + +The frequencies broadcast by Mount Dandenong are: + +Table 1.

Please check at the DVB wiki + at https://linuxtv.org/wiki for more updated info. + +Some very frequently asked questions about linuxtv-dvb + +1. The signal seems to die a few seconds after tuning. + + It's not a bug, it's a feature. Because the frontends have + significant power requirements (and hence get very hot), they + are powered down if they are unused (i.e. if the frontend device + is closed). The dvb-core.o module parameter "dvb_shutdown_timeout" + allow you to change the timeout (default 5 seconds). Setting the + timeout to 0 disables the timeout feature. + +2. How can I watch TV? + + The driver distribution includes some simple utilities which + are mainly intended for testing and to demonstrate how the + DVB API works. + + Depending on whether you have a DVB-S, DVB-C or DVB-T card, use + apps/szap/szap, czap or tzap. You must supply a channel list + in ~/.[sct]zap/channels.conf. If you are lucky you can just copy + one of the supplied channel lists, or you can create a new one + by running apps/scan/scan. If you run scan on an unknown network + you might have to supply some start data in apps/scan/initial.h. + + If you have a card with a built-in hardware MPEG-decoder the + drivers create a video4linux device (/dev/v4l/video0) which + you can use to watch TV with any v4l application. xawtv is known + to work. Note that you cannot change channels with xawtv, you + have to zap using [sct]zap. If you want a nice application for + TV watching and record/playback, have a look at VDR. + + If your card does not have a hardware MPEG decoder you need + a software MPEG decoder. Mplayer or xine are known to work. + Newsflash: MythTV also has DVB support now. + Note: Only very recent versions of Mplayer and xine can decode. + MPEG2 transport streams (TS) directly. Then, run + '[sct]zap channelname -r' in one xterm, and keep it running, + and start 'mplayer - < /dev/dvb/adapter0/dvr0' or + 'xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0' in a second xterm. + That's all far from perfect, but it seems no one has written + a nice DVB application which includes a builtin software MPEG + decoder yet. + + Newsflash: Newest xine directly supports DVB. Just copy your + channels.conf to ~/.xine and start 'xine dvb://', or select + the DVB button in the xine GUI. Channel switching works using the + numpad pgup/pgdown (NP9 / NP3) keys to scroll through the channel osd + menu and pressing numpad-enter to switch to the selected channel. + + Note: Older versions of xine and mplayer understand MPEG program + streams (PS) only, and can be used in conjunction with the + ts2ps tool from the Metzler Brother's dvb-mpegtools package. + +3.
