These are useful for scanning to make an index of the available channels, tuning the chip to a chosen station or recording the channel to a file on your computer so you can watch it at a later date. &lfs71_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &dvb-apps-md5sum; Download size: &dvb-apps-size; Estimated disk space required: &dvb-apps-buildsize; Estimated build time: &dvb-apps-time; User Notes: There are many TV chips available so it is not possible to give guidance on the kernel config for all of them. lspci from and Goggle are your friends. One possible gotcha is that some pci cards (such as the Hauppauge Nova T 500) present themselves to the motherboard as a USB controller and the TV chip on the card communicates with the motherboard via this USB interface. General setup ---> [*] Prompt for development and/or incomplete code/drivers Device Drivers ---> Generic Driver Options ---> [*] Userspace firmware loading support [*] Include in-kernel firmware blobs in kernel binary (list of) External firmware blobs to build into the kernel binary (/lib/firmware) Firmware blobs root directory [*] I2C support ---> [*] I2C device interface I2C Algorithms ---> [*] I2C bit-banging interfaces [*] Multimedia support ---> [*] Video For Linux [*] DVB for Linux [*] DVB Network Support [*] Video capture adapters ---> [*] V4L USB devices ---> (as required depending on your hardware) [*] V4L PCI(e) devices ---> (as required depending on your hardware) [*] DVB/ATSC adapters ---> (as required depending on your hardware) Select the appropriate sub-options that appear when the above options are selected and recompile your kernel. dvb-apps Install DVB-Apps by running the following commands: sed -i 's/ $(lib_name).a//' Make.rules && sed -i 's/\.a/.so/g' test/*/Makefile && make This package does not come with a test suite. Now, as the root user: make install sed -i 's/ $(lib_name).a//' Make.rules and sed -i 's/\.a/.so/g' test/*/Makefile: These seds disable compiling the static libraries. ~/.tzap/channels.conf and /etc/channels.conf. ~/.tzap/channels.conf /etc/channels.conf For a user to be able to use the device files in /dev the simplest solution is to make the user part of the video group. As the root user: usermod -a -G video <USERNAME> Create a channels.conf file listing the channels available from your local transmitter. If it's a terrestrial transmitter there should be a file with its details in /usr/share/dvb/dvb-t. If it's a satellite the file should be in /usr/share/dvb/dvb-s. scan /usr/share/dvb/dvb-t/uk-WinterHill > channels.conf && mkdir -p ~/.tzap && cp channels.conf ~/.tzap If that went Ok and you saw some familiar TV channels listed in your terminal, as the root user copy it to a system wide location: cp channels.conf /etc/channels.conf To record a channel to a file: gnutv -out file bbc1.mpeg "BBC ONE" If you give it ten seconds or so to buffer you can then start to watch the file with a video player such as xine or mplayer. The advantage of watching TV via a file in this way is that it allows you to pause playback and rewind if you want, plus you can watch the file again later.
