ABSTRACT:
Improved techniques for transmission and display of video data are described. A point of sale terminal includes a processor, memory and software executed by the processor to create frames of data and to analyze the frames of data to create differential data defining differences between preceding and succeeding frames of data. The differential data can be applied to the preceding frames to construct the succeeding frames. At least one frame is transmitted to an external video interface using an external connection such as a universal serial bus port. Differential data is also transmitted to the external video interface. The differential data is applied to the frame which has been transmitted in order to create succeeding frames. The frames of video data are displayed using a display connected to the video interface.
