Abstract:
A remote controller is described. The remote controller can remote control a plurality of electrical equipments, e.g. digital video recorders, simultaneously or respectively. The remote controller includes a signal emitter, a memory, and a plurality of keys. The memory stores a plurality of controller identification codes, and the keys can select at least one of the controller identification codes and the same is sent to the electrical equipments through the signal emitter. The electrical equipment compares the controller identification code with an equipment identification code stored in the electrical equipment when the electrical equipment receives the controller identification code. If the controller identification code corresponds to the equipment identification code, the electrical equipment executes subsequent commands from the remote controller, and if the controller identification code does not correspond to the equipment identification code, the electrical equipment refuses to execute the subsequent commands from the remote controller.
Abstract:
A method for reducing memory size and amount of data accessed of a buffered-frame storage device in a video codec is provided. It is applicable to a codec compliant with a video encoding and decoding standard. When a block is decompressed, the block is stored in the buffered-frame storage device using either compression data or reconstructed data based on its encoded mode and the positions of its reference frames, or based on a topological pattern and a pre-determined memory capacity constraint. With this method, not only the memory size of the buffered-frame storage device, but also the computational complexity requirement for decoding compression data of reference frames is reduced. The present invention compromises among the buffered-frame memory size, amount of data accessed, and computational complexity requirement.

Abstract:
A monitoring system including N cameras, a digital video recorder (DVR), a monitor, a remote controller, a receiver and a host is provided. N is a positive integer. The N cameras successively shoot N sceneries, and output N successive images accordingly. The DVR receives and stores the N successive images. The monitor displays a monitoring screen. The remote controller outputs a wireless remote signal. The receiver receives the wireless remote signal and outputs a wire transmit signal accordingly. The host controls the monitor to display at least the successive image in the monitoring screen. The host has an on screen display (OSD) program. When the controller receives the wire transmit signal, the host utilizes the OSD program to process the wire transmit signal to become a screen adjusting signal. The host adjusts the monitoring screen according to the screen adjusting signal.
