linuxtv-dvb-apps-1.?
======================
Linux DVB API applications and utilities.
All applications support the DVB-S, DVB-C, DVB-T, and ATSC standards.
Main User Applications:
util/scan - Scan for channels on your digital TV device.
util/gnutv - Tune, watch and stream your TV.
General Utilities:
util/dvbdate - Set your clock from digital TV.
util/dvbnet - Control digital data network interfaces.
util/dvbtraffic - Monitor traffic on a digital device.
util/femon - Monitor the tuning on a digital TV device.
util/zap - *Just* tunes a digital device - really intended for developers.
util/gotox - Simple Rotor control utility
util/alevt - Teletext capture and display utility
Hardware Specific Utilities:
util/av7110_loadkeys - Load remote keys into an av7110 based card
util/dib3000-watch - Monitor DIB3000 demodulators
util/dst-utils - Utilities for DST based cards.
util/ttusb_dec_reset - Reset a TechnoTrends TTUSB DEC device.
Libraries:
lib/libdvbapi - Interface library to digital TV devices.
lib/libdvbcfg - Library to parse/create digital TV channel configuration files.
lib/libdvbsec - Library for Satellite Equipment Control operations.
lib/libucsi - Fast MPEG2 Transport Stream SI table parsing library.
lib/libdvben50221- Complete implementation of a Cenelec EN 50221 CAM stack.
lib/libdvbmisc - Miscellaneous utilities used by the other libraries.
Various testing applications also live in test.
For convenience, dvb-apps contains a copy of the DVB API include
files as they are contained in the linuxtv-dvb-1.? release
and the 2.6.x Linux kernel.
AleVT is not compiled by the main Makefile, because it depends on external
libraries which might not be available in your system (see util/alevt/README for
details). If you have the required libraries, to compile AleVT go to util/alevt/
and type "make".
