1 | 1 | Andreas Smas | There are a few problems with how the TV adapter tab is implemented today |
---|---|---|---|
2 | |||
3 | 2 | Andreas Smas | * It cannot handle a large amount of services. With DVB-S you can easily hit >1k services. Ticket #100 |
4 | * It's hard (but possible via sorting) to see which services that is transmitted on which mux. |
||
5 | * The DVB satconf solution is a bit cumbersome |
||
6 | * Updates to the quality meter indicator refreshed the grid in a way that is bad UX. Ticket #108 |
||
7 | 1 | Andreas Smas | |
8 | 4 | Andreas Smas | Therefore the plan is to totally redesign how Tvheadend interacts with hardware. |
9 | This rewrite will not be configuration compatible and will therefore bump Tvheadend version to 3.x |

87 | = Device mapper = |
||
88 | |||
89 | Upon startup Tvheadend will try to map the available hardware to the adapters as good as it can. |
||
90 | In Tvheadend 2.x it was required that the stored configuration about the adapter exactly matched the plugged in hardware. |
||
91 | |||
92 | Instead Tvheadend 3.x will try to map hardware to configured devices according to the following ruleset: |
||
93 | |||
94 | * device type AND device name AND bus-id AND device path |
||
95 | * device type AND device name AND bus-id |
||
96 | * device type AND device name |
||
97 | * device type AND bus-id |
||
98 | * device type |
||
99 | |||
100 | ||device path||Path in filesystem||/dev/dvb/...|| |
||
101 | ||bus-id||Hardware address||Bus 001 Device 004: ID 0ccd:0038 TerraTec Electronic GmbH Cinergy T2 DVB-T Receiver |
||
102 | ||device-name||Name of device(vendor) as reported via DVB API||ST STV0297 DVB-C|| |
||
103 | ||device-type||Frontend type(s)||DVB-T, DVB-C, etc|| |
||
104 | |||
105 | 5 | Andreas Smas | It will start will all devices and try rule 1 then all devices that could not be mapped and rule 2, and so on. |
106 | 4 | Andreas Smas | |
107 | This will mitigate problems when USB controllers probe devices in different order, etc |
||
108 | |||
109 | Also you can swap your DVB hardware to a new one (different vendor) and still have tvheadend map it correctly. |
