The invention relates to a signal processing method and system used in an electric device carrying a remote controller; wherein, a plurality of common keys and function keys for combining with the common keys to form combination keys are arranged on the remote controller. The method comprises the following steps: after receiving the remote control signals transmitted from the remote controller, the electronic device judges the key types corresponding to the remote control signals; if the key types is function keys and the remote control signals transmitted reach a certain amount, the electronic device will detect if the remote controller transmits the remote control signals. If the remote control signals are corresponding to the ordinary keys, the remote control signals corresponding to the function keys and common keys are output to the electronic device in the forms of the signals corresponding to the combination keys, which are used by the electronic device to conduct relevant processing. Therefore, the invention has the advantages that: the electronic device can be controlled by means of the combination keys under the prior remote control device communications protocols.
Description
technical field [0001] The present invention relates to a signal processing method and system, and more specifically, relates to an electronic device applied to a remote control device equipped with common keys and function keys that can be used to cooperate with the common keys to form a combination key, and can be used in Under the existing communication protocol of the remote control device, the signal processing method and the system of controlling the electronic equipment are controlled by means of combination keys. Background technique [0002] Usually, many electronic devices such as TVs, digital TVs or computers are equipped with remote controllers. However, according to the communication protocol of the current remote controllers, when a button is pressed on the remote controller for a long time, the remote controller will continue to The remote control information corresponding to the button is transmitted to the electronic device. At this time, if the user does no...
