Abstract: An LED light bulb includes a holder for electrically connecting with a power source, an LED mounted on the holder, an envelope mounted on the holder and covering the LED, and a light dispersing plate attached to an inner surface of the envelope. The light dispersing plate is made of a transparent material with a plurality of irregular air bubbles therein. Light generated by the LED and radiating to the envelope is refracted, reflected and scattered by the bulbs before the light emits out of the LED light bulb.

The communication device transmits a recording instruction or a watching instruction to the multimedia device according to the user's choice, and the multimedia device records the scheduled program or tunes in to the scheduled program as chosen by the user. A prompt method for selected scheduled programs is also provided.

Abstract: A recording device for recording a program is provided. The recording device has a local storing unit and communicates with a network storage device. The recording unit transmits the recorded program to the network storage device, to allow users access to the network storage device to watch or download the recorded program. When the recording device is disconnected from the network storage device, the recording device stores the recorded program in the local storing unit temporarily, and then transmits the record program in the local storing unit to the network storage device when the recording device reconnects with the network storage device, to avoid the loss of the recorded program. A method for recording a program is also provided.

Abstract: A recording device for recording a program includes a display, a setting unit, a recording unit, a controlling unit, and a detecting unit. The setting unit sets recording parameters in response to users' operations. The recording unit records the program according to the set recording parameters and generates a control signal when the recording process for recording the program is finished. The control unit displays an indicator on the display to indicate the recorded program in response to the control signal. The detection unit detects whether the recorded program is opened. The control unit removes the indicator corresponding to the recorded program when the recorded program is detected to be opened. A method for recording a program is also provided.
