A system for modifying display information on a first device to be viewable on a second device, the system comprising:

• a memory operable to store computer-executable components;
• and
• one or more processors operable to execute the computer-executable components stored within the memory to perform:
• converting a resolution of a source image frame from a first resolution to a second resolution to produce a first intermediate image frame at the second resolution;
• receiving the first intermediate image frame;
• converting a vertical or a horizontal image size of the first intermediate image frame to another vertical or another horizontal image frame size to produce a first viewable image frame;
• receiving and displaying the first viewable image frame from the image conversion component on a first display;
• performing a color space conversion comprising a luminance conversion and a chrominance conversion by receiving the first viewable image frame and converting a first set of luminance values and a first set of chrominance values of the first viewable image frame to a second intermediate image frame having a second set of luminance values and a second set of chrominance values;
• and
• encoding the second intermediate image frame in a format to be displayed on a second display,
• wherein the source image frame, the first intermediate image frame, the first viewable image frame, the first set of luminance values, and the first set of chrominance values are stored in separate input buffers on the first device.

A non-transitory computer readable storage medium comprising instructions that cause one or more processors to perform a method for modifying display information on a first device to be viewable on a second device, the method comprising:

• converting a resolution of a source image frame from a first resolution to a second resolution to produce a first intermediate image frame at the second resolution;
• receiving the first intermediate image frame;
• converting a vertical or a horizontal image size of the first intermediate image frame to another vertical or another horizontal image frame size to produce a first viewable image frame;
• receiving and displaying the first viewable image frame from the image conversion component on a first display;
• performing a color space conversion comprising a luminance conversion and a chrominance conversion by receiving the first viewable image frame and converting a first set of luminance values and a first set of chrominance values of the first viewable image frame to a second intermediate image frame having a second set of luminance values and a second set of chrominance values;
• and
• encoding the second intermediate image frame in a format to be displayed on a second display,
• wherein the source image frame, the first intermediate image frame, the first viewable image frame, the first set of luminance values, and the first set of chrominance values are stored in separate input buffers on the first device.

A first device, having a first display and a first camera, operable to modify display information to be viewable on a second device having a second display, the first device comprising:

• at least one processor;
• and
• a non-transitory computer readable medium comprising instructions that cause the at least one processor to perform a method comprising:
• receiving video information from the first camera of the first device;
• receiving a video conference request from the second device, wherein the video conference request comprises information related to a video format for displaying the video information on the second display of the second device;
• converting the video information to the video format;
• and
• transmitting video in the video format.
