System, method and computer program product for generating remote views in a virtual mobile device platform using efficient macroblock comparison during display encoding, including efficient detection of unchanged macroblocks

A method for efficient frame processing in a virtual mobile device platform, comprising:

• at a virtual mobile device platform coupled to a physical mobile device over a network,
• executing a virtual mobile device on a virtual machine, the virtual mobile device associated with the physical mobile device communicating with the virtual mobile device platform over the network, the virtual mobile device including a guest operating system (OS) and one or more applications executing on the guest OS, the guest OS generating a frame of display data from an application executing on the guest OS;
• generating a converted frame by an input/output (I/O) thread of a video encoder by performing color space conversion on the frame of display data generated by the guest OS;
• generating an encoded frame at a display encoder of the video encoder by encoding the converted frame generated by the I/O thread, wherein the I/O thread includes a zero motion vector (ZMV) detector to identify, for each macroblock of the frame, whether the macroblock is a ZMV macroblock by comparing the frame to a previous frame;
• and
• sending, by the virtual mobile device platform, the encoded frame to the physical mobile device.
