A network device to control a transmission rate of one or more fax data units transferred between a transmitting and a receiving network device. The combination of the switching layer of ZnTe and the electrodes of TiN or Pt is designed to achieve desirable performance characteristics, such as low current leakage as well as low and consistent switching currents. Also, the improved cooling methodology for high brightness light emitting diodes employs one or more high-density, high-surface-area, single or multiple-element metallic structures having superior heat-transfer properties in the presence of low-speed, minimally turbulent air flow, and enhanced electronic-power-management. The user may also be provided options for displaying, processing, creating time lapse videos of, or sharing captured image data or video data. In this manner, the video coder may update precisions used to represent depth range values for coding multiview plus depth video data.
