A pixel circuit for an organic light emitting display includes first, second, third, fourth, fifth, and sixth MOS transistors, a first capacitor, and an organic light emitting diode. The remote control associated with the TV has a microphone and speaker so that a person can use the RC not only to control the TV but also to respond to phone calls, with the TV system relaying voice signals from the RC back to the phone. Recording is carried out in one or several cycles, the brightness values of the corresponding points in the images are averaged for all recording cycles, the significant brightness range of the averaged image is established and broadened by way of re-calculation with regard to the entire dynamic range of the display device. The storage management host may be a terminal server that provides both Ethernet access to a local area network connected to the master storage units and serial communication with the master storage units. The master subnet manager is elected from the set of subnet managers through the master election, wherein other subnet managers within the number of subnet managers poll the master subnet manager to allow the other subnet managers to elect a new master subnet manager if the master subnet manager fails.
