Patent number: 11582529Abstract: A satellite IRD (Integrated Receiver Decoder) complies with DiSEqC protocol and is capable of receiving a program of a specific channel from a single cable interface device through a cable. The DiSEqC transmitter transmits a first command corresponding to the specific channel to the single cable interface device through the I/O interface and the cable. The DiSEqC receiver acquires a second command transmitted on the cable through the I/O interface in response to the DiSEqC transmitter transmitting the first command. The detecting circuit compares the second command with the first command to generate a comparison result. The DiSEqC receiver monitors the I/O interface in response to the comparison result indicating that the first command and the second command are different to determine whether there is a command other than the first command transmitted on the cable.Type: GrantFiled: June 18, 2020Date of Patent: February 14, 2023Assignee: NOVATEK Microelectronics Corp.Inventors: Guo-Tian Su, Chun-Chien Chien
