Patent number: 11943077Abstract: A multidrop network system includes N network devices. The N network devices include a master device and multiple slave devices, and each network device has an identification code as its own identification in the multidrop network system. The N network devices have N identification codes and obtain transmission opportunities in turn according to the N identification codes in each round of data transmission. Each network device performs a count operation to generate a current count value, and when the identification code of a network device is the same as the current count value, this network device obtains a transmission opportunity. After a device obtains the transmission opportunity, it determines whether a cut-in signal from another network device is observed in a front duration of a predetermined time slot, and then determines whether to abandon/defer the right to start transmitting in the remaining duration of the predetermined time slot.Type: GrantFiled: May 31, 2022Date of Patent: March 26, 2024Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Yung-Le Chang, Wen-Chih Fang, Deng-Shian Wang, Shieh-Hsing Kuo
