- ################# SETUP ######################
- 1. ./setup
- 2. ./getVersion ip_address_of_Pi_target_device
- 3. make
- 4. ./deploy ip_address_of_Pi_target_device
- ################# TUNE TOOL ######################
- Use SSH in order to use the applications:
- ssh pi@ip_address_of_Pi_target_device
- The default passowrd is:
- raspberry
- The status messages have the following meaning:
- status 0x1f --- The demodulator status bits.
- 0x1f means all bits set, everything ok.
- signal [0x0000...0xffff] --- Signal Strength. Values above 0x8000 should be ok.
- snr [0x0000...0xffff] --- Signal/Noise Ratio. Values above 0x8000 are ok.
- ber [0...0xffffffff] --- Bit Error Rate. The less the better.
- unc [0...0xffffffff] --- Number of Uncorrectable Blocks.
- Small numbers are Preferable.
- If everything is alright and all frontend circuits are working stable
- (are locked) you should see a FE_HAS_LOCK in the rightmost line.
- ################ Example usage ######################
- ON THE PI Device
- $ cd /home/pi/Desktop/sonyEw100/tuneTool
- $ ./tune -c channels.conf -r 'BTV'
- [keep it running in one console]
- The output of the program should look like this:
- using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
- reading channels from file 'channels.conf'
- Version: 5.11 FE_CAN { DVB-T + DVB-T2 }
- tuning to 626000000 Hz
- video pid 0x13f8, audio pid 0x13f9
- status 00 | signal 9eb7 | snr 07dc | ber 00000000 | unc 76f434f8 |
- status 1f | signal 9f24 | snr 7a65 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

- status 1f | signal 9c95 | snr 79b2 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
- 2. In another terminal window start the ./test_pes tool which
- takes the output of an audio/video encoder(MPEG2) stream. The content
- of the outfile is in PES(Packetized Elementary Stream) packets.
- *Notice that the audio pid must match the one of our channel.
- It is also displayed on line 19.
- $ cd /home/pi/Desktop/sonyEw100/pesTool
- $ ./test_pes 0x13f9 audioPes
- test_pes: using '/dev/dvb/adapter0/demux0'
- PID 0x13f9
- output to 'audioPes'

- 3. Alternatively dump the MPEG transport stream to a file using another terminal window
- $ cat /dev/dvb/adapter0/dvr0 > /tmp/recording.ts
