13 | help | ||
14 | Here you can fine-tune some parameters of the CinergyT2 driver. | ||
15 | |||
16 | Normally you don't need to touch this, but in exotic setups you | ||
17 | may fine-tune your setup and adjust e.g. DMA buffer sizes for | ||
18 | a particular application. | ||

26 | USB Request Blocks for Highspeed Stream transfers are scheduled in | ||

53 | help | ||
54 | This is the interval for status readouts from the demodulator. | ||
55 | You may try lower values if you need more responsive signal quality | ||
56 | measurements. | ||
57 | |||
58 | Please keep in mind that these updates cause traffic on the tuner | ||
59 | control bus and thus may or may not affect receiption sensitivity. | ||
60 | |||
61 | The default value should be a safe choice for common applications. | ||

81 | help | ||
82 | If you have a very fast-repeating remote control you can try lower | ||
83 | values, for normal consumer receivers the default value should be | ||
84 | a safe choice. | ||
