But remaining each device must will be by manually setting by the user.The domestic network system of conventional art exists following problem.The 1st, because to being connected the time of each device on the network, all need be by the user by manually setting, so very loaded down with trivial details.The 2nd and since time of each device by the user by manually setting, therefore each other can be consistent.
Summary of the invention
Purpose of the present invention is developed in order to solve above-mentioned traditional problem, its purpose is to provide a kind of time setting method of domestic network system, this method need not gone in addition to set and can carry out time set automatically and accurately yet by the user, simultaneously is consistent the time of all devices.
Domestic network system time setting method of the present invention is characterized in that: be provided with a some device in forming home network, and from outside acquisition time information, and the stage that stores; Be provided with by the device that is storing temporal information and send instruction, transmit the stage of temporal information separately to the device of remainder; Be provided with the stage that sends instruction back wait acknowledge temporal information; Be provided with the device that is storing temporal information, the temporal information of being replied by other device temporal information with oneself is compared,, so just the temporal information of oneself is sent to corresponding device thereof, and go to set the stage of the time of related device if inconsistent.
In the present invention, also have a feature to be, the device of acquisition time information will be the broadcast program receiver of analog form or digital form, and can connect the Internet and can the device of data download in a kind of.
The time setting method of domestic network system of the present invention, because in being connected to the device of network, by some temporal informations of obtaining with reliability, then with certain cycle, when perhaps device is reset, when perhaps connecting new device, will all be desynchronized the time of each remaining device, need use by manually coming the trouble of setting-up time by the user so can not only remove, and can also often aim at the time of all devices exactly.
