The mobile terminal according to any of claims 7 to 9, wherein the CPU is configured to, after receiving the remote video decoding mode selection information input by the user, enable the remote video decoding mode, stop DSP software tasks of the mobile terminal, cut off data communication between the CPU and the DSP, and place the DSP in a sleep state.
11. The mobile terminal according to claim 10, wherein the virtual coprocessor task module is specifically configured to receive a video data block to be decoded and a decoding command sent by its CPU, buffer-process the video data block and the decoding command, and send the buffered video data block to the remote video decoding task module;
the remote video decoding task module is used for converting a decoding command sent by the virtual coprocessor task module into a remote calling command of a distributed program interface of the video decoder, binding and packaging the remote calling command and a video data block sent by the virtual coprocessor task module, and sending a data packet to the transmission adaptation task submodule;
and the transmission adaptation task submodule is used for converting a wireless protocol data format of the received data packet, transmitting the data packet to the wireless task module of the mobile terminal and transmitting the data packet to the wireless task module of the computing entity by the wireless task module of the mobile terminal.
12. The mobile terminal of claim 11, wherein the CPU is further configured to switch the remote video decoding mode to the local video decoding mode when detecting that the remote video connection of the remote video connection module is disconnected, close the remote video connection module, the virtual coprocessor task module, and the remote video decoding task module, and wake up the DSP and start a DSP software task.
