determining a target bottom-layer processing from among a plurality of bottom-layer processings, wherein the determining is based on the processing demand information; and
transmitting the target image to the target bottom-layer processing based on the given transmission protocol.

2. The data processing method according to claim 1 , wherein receiving the target data transmitted by the external module based on the transmission parameter comprises:
receiving at least one data packet of the target data transmitted by the external module based on the transmission parameter; and
determining the target data based on the at least one data packet.

3. The data processing method according to claim 2 , wherein determining the target data based on the at least one data packet comprises:
extracting data from the at least one data packet respectively in response to detecting that the at least one data packet meets a given requirement; and
generating the target data based on the data.

4. The data processing method according to claim 3 , wherein detecting that the at least one data packet meets the given requirement comprises:
determining that there is no loss of data of the at least one data packet.

5. The data processing method according to claim 3 , wherein detecting that the at least one data packet meets the given requirement comprises:
determining that there is no damage to the data of the at least one data packet.

6. The data processing method according to claim 3 , further comprising:
sending a data repeat request to the external module in response to detecting that the at least one data packet does not meet the given requirement, wherein the data repeat request is used for requesting the external module to resend the target data.

7. The data processing method according to claim 1 , further comprising:
executing an operation corresponding to a control instruction in response to receiving the control instruction in a process of receiving the target data, wherein the operation comprises at least one of:
interrupting transmission of the target data, pausing transmission of the target data and ending transmission of the target data.

8. The data processing method according to claim 1 , wherein the given transmission protocol comprises a User Datagram Protocol (UDP) transmission protocol or a Transmission Control Protocol (TCP) protocol.

9. A data processing method, performed by an external module connected into a terminal device and comprising:
