According to an embodiment of the present disclosure, if the first data transceiving component further includes a first data transmission component, the data processing apparatus 200 may be connected to the input device 3 through the first data transmission component, and the first processor 210 may further send the control information received through the first data transmission component to the cloud device, for example. The control information can be responded by the cloud end equipment or forwarded to the terminal equipment remotely connected with the cloud end equipment by the cloud end equipment, so that the remote control of the cloud end equipment or the terminal equipment remotely connected with the cloud end equipment is realized.
Illustratively, the control information may include, for example, parameters of one or more control events, one control event corresponding to one operation of the input device by the user.

An application principle of the data processing apparatus provided by the present disclosure in the first scenario will be described below with reference to fig. 4.
Fig. 4 is a schematic diagram of an application principle of a data processing apparatus according to an embodiment of the present disclosure.
As shown in fig. 4, in the first scenario 400, a display device 41, a first data processing apparatus 42, a cloud device 43, a second data processing apparatus 44 adapted to the first data processing apparatus 42, and a terminal device 45 may be included. Wherein the first data processing device 42 is a device comprising a first processor as described above and the second data processing device 44 is a device comprising a second processor as described above.
In this first scenario, the second data processing apparatus 44 and the first data processing apparatus 42 may communicate with each other through the cloud device 43. When the two data processing apparatuses perform communication, the transmitted data may be added with indication information to indicate whether the destination of the transmitted data is the first data processing apparatus or the second data processing apparatus, so as to ensure that the cloud device 43 can forward the transmitted data between the two adapted data processing apparatuses when forwarding the transmitted data. The indication information may be identification information such as an ID code of the data processing apparatus.
Illustratively, the second processor of the second data processing device 44 may obtain the first multimedia data collected by the terminal equipment 45 through the video input component. If the first multimedia data is acquired, the indication information (first indication information) of the adapted first data processing device 42 is added to the first multimedia data. The first multimedia data containing the first indication information is then sent to the cloud device 43 through the second network communication component. After receiving the first multimedia data including the first indication information, the cloud device 43 may forward the first multimedia data to the first network communication component of the first data processing apparatus 42 according to the first indication information. The first processor of the first data processing apparatus 42 may send the first multimedia data containing the first indication information to the display device 41 through the video output component in response to the first network communication component receiving the first multimedia data. Through this process, the display device 41 can display a display image of the terminal device 45, a video, or an audio played by the playing terminal device 45.
Illustratively, the first multimedia data may be encoded and compressed, for example, before the second data processing device 44 transmits the first multimedia data. The first indication information is then added to the encoded and compressed multimedia data, and the encoded and compressed multimedia data including the first indication information is sent to the cloud device 43. Accordingly, after acquiring the multimedia data including the first indication information, the first data processing device 42 may decompress and decode the multimedia data, and send the decoded multimedia data to the display device 41. By compressing and transmitting the multimedia data, the data transmission efficiency can be improved, and the network bandwidth requirement can be reduced.
According to an embodiment of the present disclosure, as shown in fig. 4, an input device 46 may also be included in the first scenario 400. The first data processing means 42 may be connected to the input device 46 via a first data transmission component and the second data processing means 44 may be connected to the terminal device 45 via a second data transmission component. Through the information interaction between the first data processing device 42 and the second data processing device 44, the input device 46 can remotely control the terminal device 45, so as to update the multimedia data of the terminal device 45.
For example, after the user views the multimedia data through the display device 41, if the user wants to update the multimedia data of the terminal device 45, the user may cause the input device 46 to send the first control information to the first data processing apparatus 42 through the first data transmission component of the first data processing apparatus 42 by a touch operation on the input device 46. The first processor of the first data processing apparatus 42 may, for example, generate the second control information by adding second indication information indicating the second data processing apparatus 44 to the first control information in response to receiving the first control information through the first data transmission component. The second control information is then sent to the cloud device 43 through the first network communication component. After receiving the second control information, the cloud device 43 may forward the second control information to the second data processing apparatus 44 according to the second indication information in the second control information. The second processor of the second data processing arrangement 44 may, in response to receiving the second control information via the second network communication component, send the second control information to the terminal device 45 via the second data transmission component.
Upon receiving the second control information, the terminal device 45 may update the displayed or played multimedia data in response to the control information, and send the updated multimedia data to the second data processing apparatus 44 in a manner similar to the manner in which the first multimedia data is sent.
