+Use this setting to translate broadcaster-specific, country-specific or other customised genre tags into tags recognised by tvheadend.
+
+Example:
+
+```
+192=20
+208=16
+224=35
+```
+
+| Line | Meaning |
+| ------------- | ------------- |
+|192=20|Translate decimal 192 (0xC0 = Australian-specific 'comedy') to decimal 20 (0x14 = ETSI standard 'comedy').|
+|208=16|Translate decimal 208 (0xD0 = Australian-specific 'drama') to decimal 16 (0x10 = ETSI standard 'movie/drama (general)').|
+|224=35|Translate decimal 224 (0xE0 = Australian-specific 'documentary') to decimal 35 (0x23 = ETSI standard 'documentary').|
+
