A video playback apparatus includes a user interface, an image processing module and a playback module. The user interface allows a user to select an original playback mode or a compensated playback mode, and outputs a corresponding playback mode signal. The image processing module is for receiving a video signal and the playback mode signal and sending the video signal substantially unaltered or compensating the video signal before sending according to the playback mode signal. The playback module is for playing back the video signal from the image processing module. The aforementioned video playback apparatus provides the user different playback mode selections for the same video.

A quadri-filar helical antenna structure includes a cylindrical body having a relative dielectric constant greater than 4, and four radial metal plates on a distal end of the cylindrical body, and each radial metal plate is extended along the cylindrical body. The ends of every two adjacent radial metal plates are connected to form two antenna structures, and a circuit board is fixed. A ground surface is installed on one side of the circuit board and coupled to one of the antennas. An impedance matching circuit is installed on another side of the circuit board, and one end of the impedance matching circuit is coupled to another antenna. A feeder is installed at another end of the impedance matching circuit. Four radial metal plates having an electric length about odd multiples of a quarter of wavelength of the cylindrical body can receive satellite signals.

The present invention discloses a quadri-filar helix antenna structure, which comprises a cylindrical body made of a dielectric material with a relative dielectric constant εr greater than 4, and four radiating metal plates disposed on a distal end surface of the cylindrical body and extended along the radial direction of the center of the cylindrical body to its periphery and then along the radial direction in a spiral course on the circumferential surface thereof to its periphery on the other end respectively, wherein the ends of every two adjacent radiating metal plates are coupled with each other to constitute two sets of antenna structures, a penetrating hole is disposed at the central position of the cylindrical body and is precisely embedded into a coaxial cable, and a shield cable disposed at the periphery on one end of the coaxial cable is coupled to an end of another set of antenna structure. Therefore, the antenna not only reduces the overall volume, but also greatly lowers its production costs.

A parity-check-code decoder includes: a verifying device that multiplies (N) bit nodes by a matrix provided with (N) columns so as to obtain a plurality of check nodes; a reliability generator that generates a reliability index for each of the bit nodes in accordance with a channel; a reliability-updating device that uses the bit nodes and the check nodes to exchange message iteratively, and following each iteration, updates (N) exchange results corresponding to the (N) columns; and a recording controller that includes a separator, a quantizing determiner and a quantizer. The separator divides the matrix into at least one column group based on the characterizing signals. The quantizing determiner determines a shift signal for each column group based on the characterizing signals. The quantizer quantizes the characterizing signals according to the shift signals for subsequent output.

An earthquake-triggered emergency indicator includes an earthquake detector, an indicator, a controller, and a battery module. The earthquake detector is configured for detecting a vibration. The indicator is configured for generating an indication signal in a form of light, sound or vibration to guide a user to take an emergency measure. The controller is configured for generating a trigger signal based on a magnitude and a lasting time of the vibration so as to trigger the indicator to output the correspondent indication signal. The battery module is configured for providing power supply required for operation of the earthquake-triggered emergency indicator. Preferably, the above-mentioned earthquake-triggered emergency indicator includes a wireless communication module for connecting multiple earthquake-triggered emergency indicators to reduce adverse effects caused by malfunctioning single emergency indicator.

A vehicle recording apparatus includes a video capturing unit, a storage unit and a processing unit. The video capturing unit is for capturing a video. The storage unit includes a file including an index block and a plurality of storage blocks. The processing unit stores the video into the storage block according to a data index in the index block. The aforementioned vehicle recording apparatus may prevent an execution of file opening or closing from causing the video unable to be recorded, or an abnormal file close from leading to the damage of the file. A video recording method is also disclosed.
