Abstract
A HID system comprising a HID is disclosed. The HID comprises a data generation device, configured to generate a plurality of first data units with target data in a first mode; and a transmission device, configured to selectively use second data units or third data units to output the target data in the first mode. Second sizes of the second data units are different from third sizes of the third data units. By such system, packets with proper sizes may be selected, thus the required time of processing packets and necessary power consumption for transmitting packets may be optimized.

A HID (Human Interface Device) system, comprising:
- a HID, comprising:
- a data generation circuit, configured to generate a plurality of first packets with target data in a first mode;
- and
- a transmission circuit configured to selectively use second packets or third packets to output the target data in the first mode, according to data quantities of the target data or according to a parameter used by the HID;
- wherein second sizes of the second packets are different from the third sizes of the third packets;
- wherein the second sizes are smaller than the first sizes;
- wherein the third sizes are smaller than or equal to the first sizes.
A data transmission method, applied to an HID (Human Interface Device) system comprising a HID with a data generation circuit and a transmission circuit, comprising:
- (a) generating a plurality of first packets with target data by the data generation circuit in a first mode;
- and
- (b) selectively using second packets or third packets to output the target data by the transmission circuit in the first mode, according to data quantities of the target data or according to a parameter used by the HID;
- wherein second sizes of the second packets are different from third sizes of the third packets;
- wherein the second sizes are smaller than the first sizes;
- wherein the third sizes are smaller than or equal to the first sizes.
A HID (Human Interface Device) system, comprising:
- a HID, comprising:
- a data generation circuit, configured to generate an analog data signal containing analog target data;
- and
- a transmission devicecircuit, configured to transform the analog target data to digital target data, and configured to selectively use first digital packets or second digital packets to output the digital target data;
- wherein first sizes of the first digital packets are different from the second sizes of the second digital packets.
