Get array of all available instances in the system:
console.log(stbDvbManager.list);
Get first available input:
var input = stbDvbManager.list[0];
Manual control of antenna power state:
// turn on
input.antennaPower = true;
// turn off
input.antennaPower = false;
Get information about input:
console.log('current state of this tuner:', input.state);
console.log('signal level:', input.signalLevel);
console.log('signal quality:', input.signalQuality);
console.log('supported scan types for this tuner:', input.supportedScanTypes);
console.log('currently supported scan types for this tuner:', input.currentScanTypes);
console.log('bit error rate:', input.bitErrorRate);
Set current scan type for this input:
console.log('DVB-C signal:', input.setSignalType(1));
console.log('DVB-T signal:', input.setSignalType(2));
console.log('DVB-T2 signal (not available for MAG270):', input.setSignalType(3));
console.log('DVB-S/DVB-S2 signal:', input.setSignalType(4));
Set event listeners to handle received data:
input.onScanProgress = function ( info ) {
console.log('DVB channels scanning is in progress:', info);
// {"state":"searching","channel":0,"frequency":51000,"progress":0,"inputIndex":0,"polarization":"H"}
};
input.onChannelFound = function ( info ) {
console.log('DVB channel is found:', info);
// {"frequency":474000,"inputIndex":0,"bandwidth":4000,"polarization":"H","modulation":-1,"symbolRate":6875800,"id":"C.0.000474.06875-01","type":1,"uri":"dvb://C.0.000474.06875-01","scrambled":false,"name":"MEGA","provider":"","isRadio":false,"channelNumber":0}
};
input.onAntennaPower = function () {
console.log('DVB antenna is powered off.');
};
Start channel scanning (parameters explanation see in stbDvbInput.startScan method):
input.startScan({
from: 10,
to: 100,
type: 2,
bandwidth: 6,
step: 5,
modulation: 0,
scanMode: 0,
frequency: 12,
networkId: 0
});
Tune receiver to specified frequency (parameters explanation see in stbDvbInput.tune method):
input.tune({
frequency: 10,
polarization: 'V',
symbolRate: 2,
type: 2
});
Stop channel scan:
input.stopScan();
Make a new channel list as a subset of parent list:
var channelList1, channelList2;
channelList1 = stbDvbManager.createChannelList(['lt', 'channelNumber', 123]);
console.log('any channels with LCN less than 123:', channelList1);
channelList2 = stbDvbManager.createChannelList();
console.log(channelList2);
Root list of all available channels from all inputs:
console.log(stbDvbManager.channelList);
Get the channel index in this channel list:
channelList2.add(channelList1.getChannel('123').id);
Remove the given channel from this channel list with check operation status:
if ( !channelList2.remove('ccid:0.12.1') ) {
console.log('Was not able to remove a channel!');
}
if ( !channelList2.remove(5) ) {
console.log('Was not able to remove a channel!');
}
Get channel detailed info:
console.log('channel detailed info:', channelList2.getChannel(5));
console.log('channel detailed info:', channelList2.getChannel('ccid:0.12.1'));
Get channel range:
console.log('channel range:', channelList2.slice(1, 5));
Get the channel index in this channel list:
console.log('the channel index in this channel list:', channelList2.indexOf('ccid:0.12.1'));
Remove all channels from this channel list:
channelList2.clear();
