A method for automated channel updating is provided. In step (a), a frequency carrying channel data is detected. In step (b), it is determined whether a channel list comprises the frequency by retrieving a frequency table, where the frequency table stores information indicating whether the frequency is comprised in the channel list, and the channel list records a mapping relationship between a channel number and the frequency. In step (c), an unused channel number in the channel list is assigned to the detected frequency not in the channel list, where the unused channel number does not map to the frequency.

Systems and methods for automated channel updating

A method for automated channel installation comprises the following steps. In step (A), a frequency scanning operation is executed to lock on to a frequency. In step (B), it is determined whether the frequency scanning operation is complete, if so, the process proceeds to step (F), otherwise, to step (C). In step (C), it is determined whether the locked frequency corresponds to a reserved channel number, if so, the process proceeds to step (D), otherwise, to step (E). In step (D) the corresponding reserved channel number is assigned to the locked frequency, and then proceeds to step (A). In step (E), the locked frequency not corresponding to the reserved channel number is stored in a caching table, and then proceeds to step (A). In step (F), an unused channel number is assigned to the frequency stored, if any, in the caching table.

Systems and methods for automated channel installation consuming less time and thus increasing user convenience

A method for searching a frequency band to locate a channel. The method includes the steps of setting an initial frequency and a first frequency step; determining a frequency point based on the initial frequency and the first frequency step; determining whether the frequency point satisfies a first condition, which is continuously detecting a horizontal signal a predetermined number of times. When the first condition is satisfied, the frequency point is recorded as an entrance point. A second frequency step based on the entrance point determines a second frequency point, wherein the second frequency step is less than the first frequency step. It is then determined if a channel exists at the second frequency point. The entrance point is recorded as the updated initial frequency for the next search. The described steps are repeated for the entire frequency band.
