DVB - TOOLS

SetUp

1. ./setup
2. ./getVersion
3. make
4. ./deploy

Usage

All the dvb-applications are deployed on the Desktop of the pi device in the following maner:

/home/pi/Desktop

        ├── lib
        ├── test
        ├── util

Use SSH in order to use the applications: ssh pi@

The default passowrd is: raspberry

Note The TVHeadend service can be accessed the following way: :9981 user: pass: admin admin

Before start using the dvb-apps stop the tvheadend service since it is also using the /dev/dvb/adapter0 interfaces:

$ cd /etc/init.d $ sudo ./tvheadend stop

Linux DVB API applications and utilities.

Libraries: libdvbapi - Interface library to digital TV devices. libdvbcfg - Library to parse/create digital TV channel configuration files. libdvbsec - Library for Satellite Equipment Control operations. libucsi - Fast MPEG2 Transport Stream SI table parsing library. libdvben50221- Complete implementation of a CENELEC (European Committee for Electrotechnical Standardization) EN 50221 CAM stack. libdvbmisc - Miscellaneous utilities used by the other libraries.

Utils: 1.Main User Applications: scan: the original frequency scanning tool used to generate channel lists dvbscan: another frequency scanning tool used to generate channel lists .... some distro package managers have rebranded this as "scandvb" ... also note that "atscscan", if included, is simply a copy of dvbscan. The DVB or ATSC protocol is determined by a tuning file feed to these programs. Tuning files are kept in the scan/atsc, scan/dvb-[csth] directories. This program discovers carriers on candidate frequencies and also determines sub-channels. sub-channels may be the main program at a lower data rate or completely new content. With the output produced, a short name can be used to identify the frequency and the streams needed to get a channel. czap, szap, tzap: tuning utilities for DVB-C, DVB-S, DVB-T. These change the channel/sub-channel as identified by the file output by scan above. azap: tuning utility for ATSC. util/gnutv - Tune, watch and stream TV. I.e. a DVB UI.

2.General Utilities: util/dvbdate - Read date time information from the currently tuned multiplex. util/dvbnet - Control digital data network interfaces. DVB network interface manager (IP over DVB). util/dvbtraffic - Monitor traffic on a digital device. PID analysis of currently tuned multiplex. util/femon - Frontend (fe) monitor. Monitor the tuning status on a digital TV device. util/zap - Just tunes a digital device - really intended for developers. Note that this is a seperate app then those zap utilities listed above. util/atsc_epg - Recent versions of dvb-apps include a program to print out the next three hours worth of programs on a given frequency (for ATSC only).

3.Hardware Specific Utilities: util/av7110_loadkeys - A utiltity to load IR remote keymaps into an av7110 based card using the /proc/av7110_ir interface util/dib3000-watch - Monitor DIB3000 demodulators util/dst-utils/dst-test - Utilities for DST based cards. util/ttusb_dec_reset - Reset a TechnoTrends TTUSB DEC device.

Test: diseqc: Sends various diseqc sequences on a SAT frontend. set22k: Legacy tone switching for SAT frontends. setvoltage: Legacy voltage switching for SAT frontends. setpid: Set video and audio PIDs in the demux (only for hardware MPEG decoder) video: tiny video watching application test_sections: Hex dump of section data from stream. test_sec_ne: Like test_sections, but also test Not-Equal filter mode. test_pes: Hex dump of PES data from stream. test_tt: Demonstrate teletext decoding from PES data. test_av: Test audio and video MPEG decoder API. test_vevent: Test VIDEO_GET_EVENT and poll() for video events test_stc: Test DMX_GET_STC. test_stillimage: Display single iframes as stillimages test_dvr: Record a partial transport stream of selected PIDs to a file or a full stream if supported by the hardware
