It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

referring to fig. 1, a first embodiment of the present invention provides a method for Miracast message processing based on inheritable state machines, which is executed by a Miracast message processing device based on inheritable state machines (hereinafter referred to as a message processing device), and in particular, executed by one or more processors in the message processing device, to implement the following steps:

s101, when detecting that screen projection equipment is accessed, establishing virtual equipment for the screen projection equipment, and distributing a state machine for the virtual equipment; the state machine comprises a plurality of states at different levels, and inheritance relationships exist among the states at the different levels.

In this embodiment, the message processing device may be, for example, a smart television, a smart projector, a smart tablet, or the like, and may receive a screen projection picture sent by a screen projection device, such as a mobile phone, and display the screen projection picture on a display of the message processing device.

In this embodiment, the screen projection device and the message processing device may be connected through P2P, and when the message processing device detects that the screen projection device is accessed, the message processing device creates a virtual device for the screen projection device and allocates a state machine for the virtual device; the state machine comprises a plurality of states at different levels, and inheritance relationships exist among the states at the different levels.

As shown in fig. 2, fig. 2 shows one possible state machine. In fig. 2, the state machine includes:

a default state at a first level;

a WFD valid state at a fourth level that inherits the IP valid state;

In which a device can only be in one state, and if the device is in the P2P connection state, it is impossible to be in the P2P disconnection state at the same time. An inheritance relationship exists between the states, the inheritance relationship is represented by arrows in fig. 2, the WFD (Wi-Fi Direct, i.e., Wi-Fi screen projection) is in a sub-state of the WFD valid state, and the WFD valid state is in a sub-state of the IP valid state.

It should be noted that, in the embodiment of the present invention, the different states correspond to different states of different levels of P2P and rtsp, so as to conform to the P2P connection flow. In other embodiments of the present invention, the states of the state machine and the inheritance relationship between the states may also be set according to actual needs, and the state machine is only an example of the present invention and is not to be construed as a limitation of the present invention.

S102, obtaining the execution action of the screen projection equipment, and triggering the state machine to enter a corresponding state according to the execution action.

S103, receiving the message to be processed, and judging whether the message needs to be processed or not according to the message to be processed and the current state.

S104, when the message is judged to need to be processed, acquiring the state corresponding to the message from the current state and the parent state inherited from the current state, and processing the message in the corresponding state.

In the present embodiment, the messages can be processed in different states, for example, in the P2P disconnection state, the messages of P2P disconnection can be not processed, i.e., the messages are directly discarded. And when the P2P connection state receives the P2P disconnection message, some disconnection operations are needed.

In this embodiment, the message that is not processed by the child state may be handed over to the parent state, for example, the IP acquiring state may choose not to process the P2P disconnect message and be handed over to the parent state P2P connection state (as compared with the prior art, the P2P disconnect message needs to be processed step by step according to the connection flow, that is, the P2P disconnect message needs to be processed three times).

In this embodiment, the message processing mode may be defined by a preset message-state mapping table, which defines messages that may need to be processed and their corresponding states, so as to ensure accurate processing of the messages.

In addition, some operations can be selected when entering and leaving the state machine, such as entering the WFD conducting state, the screen projection interface can be started, and leaving the WFD state, the screen projection interface can be cancelled.

In summary, in this embodiment, when multiple Miracast screen projection occurs, one state machine is allocated to each screen projection device, and one state machine can only be in one state, the manner of processing the corresponding message in each state is different, and different states correspond to different states of different levels of P2P and rtsp, so as to attach the P2P connection flow, thereby achieving the purposes of reducing errors and improving the connection success rate. Research shows that the average success rate can be improved to more than 98% from about 80% by the method.
