Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.
Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
The invention provides a video output method of a docking station, which is applied to the docking station, as shown in fig. 3, the docking station includes a video module, a docking module and a device source interface, wherein the video module includes a video interface, the docking module includes a data interface, and the device source interface is used for being electrically connected with a device source end. Specifically, the video Interface is an HDMI (High Definition Multimedia Interface), and the HDMI can send audio and video signals at the same time, so that the installation difficulty of the system line is greatly simplified because the audio and video signals adopt the same wire. The data interface comprises one or more of a USB3.0 interface, a USB2.0 interface, an SD interface, a TF interface and a Type-C interface. The applicability of the docking station is improved by arranging a plurality of data interfaces. The equipment source interface comprises a Type-c interface, and along with the popularization of the Type-c interface on a notebook and a mobile phone, the Type-c port is increasingly favored by consumers. Therefore, the uplink port of the docking station is also designed to be a Type-c port to meet the development requirements of the market.
In a first embodiment of the docking station video output method, referring to fig. 4, the following steps are included:
step S10: when the preset condition is met, the signal switching module receives a switching instruction;
step S20: after receiving a switching instruction, the signal switching module disconnects a first signal channel between the signal switching module and the expansion module and communicates a second signal channel between the signal switching module and the video module, so that a video signal can sequentially pass through the equipment source interface, a third signal channel between the signal switching module and the equipment source interface, the signal switching module, the second signal channel and the video module to be output.
The technical problem that in the prior art, the video output of the docking station can only support the video definition output of 8K30 frames, cannot be switched to the video output with higher definition and smoothness, and cannot meet the better viewing requirement of a user is solved.
In order to solve the above technical problem, in this embodiment, when the preset condition is satisfied, the signal channel resource connected to the expansion module is supplied to the video module for the video module adds a new signal channel on the basis of the original signal channel, and the transmission amount of video output is increased, so that the video output with higher definition and smoothness is realized, and the better viewing requirement of the user is satisfied.
Specifically, a fourth signal channel is arranged between the device source interface and the video module, so that the video signal can be output through the device source interface, the fourth signal channel and the video module in sequence. The fourth signal channel is an original signal channel between the device source interface and the video module. It can be understood that before switching, the device source interface may be connected to the video module through the fourth signal channel, or may be connected to the expansion module through the third signal channel, the signal switching module, and the first signal channel in sequence, and when data transmission is performed by using the data interface, video output may also be performed by using the video interface.
Specifically, in order to ensure that the video format at the device source end can smoothly utilize the second signal channel for video output, the command module may send a switching command to the signal switching module, and at the same time, send a signal conversion command to the device source end through the device source interface, so that the device source end converts the video format into a corresponding format type that can be transmitted through the second signal channel in advance.
Specifically, the first signal path comprises RXP-RXN-TXP-TXN, the second signal path comprises RX2P-RX2N-RX3P-RX3N, and the fourth signal path comprises RX0P-RX0N-RX1P-RX 1N. With this arrangement, considering that the data interface and the device source interface are mainly used for data transmission, as data transmission involves data output and data input, corresponding differential input terminals (RXP-RXN) and differential output terminals (TXP-TXN) need to be provided, and a differential transmission group is formed by combining the differential input terminals and the differential output terminals for data transmission, so that corresponding four transmission lines need to be configured on the first signal channel and the third signal channel. When the signal switching module is switched to be connected with the video module, only the differential input end (which can be input from the perspective of the video module) is reserved because the video output is mainly involved, and because two transmission lines (TXP-TXN) are idle on the third signal channel at this time, two sets of differential input ends RX2(RX2P-RX2N) and RX3(RX3P-RX3N) are designed. And the four groups of differential input ends are matched with the other two groups of differential input ends RX0(RX0P-RX0N) and RX1(RX1P-RX1N) arranged on the fourth signal channel to improve the video output effect.
Further, a second embodiment of the video output method of the docking station is proposed based on the first embodiment, and referring to fig. 5, in step S10, the method includes the following steps:
step S11: judging whether the data interface is in an idle state or not;
step S12: and when the data interface is in an idle state, judging that a preset condition is met.
When the method is applied, whether the data interface is in an idle state is judged firstly; and when the data interface is in an idle state, judging that the preset condition is met. By the technical means, the signal switching module is switched to be connected with the video module when the data interface is in the idle state, so that the phenomenon that the signal channel resource is idle to cause resource waste is avoided.
Specifically, referring to fig. 6, in step S11, the method includes the following steps:
step S111: detecting whether the data interface generates current or not;
step S112: and when detecting that no current is generated in the data interface, judging that the data interface is in an idle state.
So set up, because data interface is connected with external equipment, and data interface must have the electric current to produce, consequently through detecting whether data interface has the electric current to produce, when detecting out that data interface does not have the electric current to produce, then judge that data interface is in idle state, the simple practicality of principle is strong.

step S13: judging whether the network interface is in an idle state or not;
step S14: and when the network interface is in an idle state, judging that a preset condition is met.
When the method is applied, whether the network interface is in an idle state is judged; and when the network interface is in an idle state, judging that the preset condition is met. Considering that a network interface is also provided on a general expansion module, the device source end is connected to the network through the network interface. By the technical means, the signal switching module is switched to be connected with the video module when the network interface is in the idle state, so that the phenomenon that the signal channel resource is idle to cause resource waste is avoided.
Specifically, referring to fig. 8, in step S13, the method includes the following steps:
step S131: detecting whether the network interface is connected with a network cable or not;
step S132: and when the network interface is not connected with the network cable, judging that the network interface is in an idle state.
According to the arrangement, because the conventional network interface is generally provided with a device for detecting whether the network interface is smoothly connected with the network, when the device detects that the network interface is not connected with a network cable, the network interface is judged to be in an idle state, the principle is simple, and the practicability is high.
