Detailed Description

In order to make the scheme of the present application better understood, the following is a brief introduction to the Universal Plug and Play (UPnP) protocol used in the present application.

The UPnP protocol is an architecture for common peer-to-peer networking of PCs and smart devices (or appliances), especially in the home. UPnP is based on Internet standards and technologies (e.g., TCP/IP, HTTP and XML) that allow such devices to automatically connect and interoperate with each other, thereby making networks (especially home networks) possible for more people. The UPnP architecture does not have a device driver and replaces the device driver with a common protocol, so that the UPnP can be used across various operating system platforms, application programs can be developed, language limitations do not exist, only the UPnP protocol is added on the basis of the existing network facilities, and the UPnP architecture can be used without adding new facilities or assuming network media again. And the UPnP device can dynamically enter the network, then obtain the IP address, learn or search the information of the operation and service which the UPnP device should perform, sense whether other devices exist and the action and the current state of the other devices, and all the operations can be automatically completed. That is, as long as any device is connected to the network, all devices on the network can immediately sense that a new device is added, the devices can communicate with each other, and can be directly used or controlled through the control end, and all the devices do not need to be set in advance, and plug and play are completely achieved.

Therefore, UPnP can fully utilize the functions of TCP/IP and network technologies, not only can seamlessly interface with similar networks, but also can control network devices and the transmission of information between devices, and based on this, the current applications of UPnP are very wide, such as home automation, printing, picture processing, audio/video entertainment, kitchen devices, automobile networks, and similar networks in public venues, and so on. For a UPnP device playing music, the current control end can only push audio to the device end to play, but cannot display lyrics, so that the method for pushing synchronous lyrics to the device end through the UPnP is provided, and the user experience is further improved.

Fig. 1 is a schematic flowchart of a lyric transmission method provided by the present application, and as shown in fig. 1, the lyric transmission method provided by the present application includes the following steps:

s101: and the control end calls the first data transmission interface to send a lyric type query instruction to the equipment end.

In a specific embodiment of the present application, the lyric type query instruction is used to instruct the device side to query and return a supported lyric type, and the control side and the device side establish a connection using a universal plug and play UPnP protocol. That is, the control end is a control end that can send out a service control message to the device end, and the device end is a device end that can respond to the service control message, return a related result, or return an error. The control terminal may be an application program on a terminal such as a mobile phone, a computer, or a PC, for example: cell phone QQ music, PCQQ music, etc., and are not limited herein. The device side may be a UPnP terminal having a music playing function and a display screen, for example: a television, a sound device, etc., and is not particularly limited herein.

In a specific embodiment of the present application, before the control end sends the lyric type query instruction to the device end through the first data transmission interface, the method further includes: the control end and the plurality of equipment ends are connected with a network in a wired or wireless mode; the control end obtains the control end IP address in the network through a Dynamic Host Configuration Protocol (DHCP) Protocol and an automatic IP address allocation Protocol, and the plurality of equipment ends obtain the corresponding equipment end IP address in the network through the DHCP Protocol and the automatic IP address allocation Protocol; the control end searches a target equipment end in the network through a Simple Service Discovery Protocol (SSDP); the control end receives device description information and service description information of the target device end, which are sent by the target device end through an SSDP protocol, wherein the device description information comprises an IP address of the device end, and the service description information of the device end comprises service control interface information, first data transmission service control interface information and second data transmission service control interface information; and the control terminal calls a service control interface of the equipment terminal to establish connection with the equipment terminal according to the IP address of the control terminal and the IP address of the target equipment terminal.
