    摘要: An apparatus and method to generate and restore an RTP (Real-Time Transmission Protocol) packet. A setting unit assigns a CTS (Composition TimeStamp), a DTS (Decoding TimeStamp), and a PSN (Packet Sequence Number) that sequentially increase according to a packet generation order for each of a plurality of SL (Synchronization Layer) packets, extracting a time stamp length and a packet sequence number length from an SLCD (SL Configuration Descriptor) within each SL packet. A packet generating unit generates a header of the SL packet accommodated in an RTP packet header and the RTP packet based on the CTS, the DTS, the PSN, the time stamp length and the packet sequence number length. Since only difference values in the CTS, the DTS, and the PSN information between a previous SL packet and the present SL packet, are recorded, a number of bits can be reduced if the CTS value rolls over and a multiple SL packet can be made for the SL packet having a time stamp length greater than 32 bits. Also, a condition that a DTS delta value should always be a positive number is met.

    摘要: A method for setting the timer of a mobile telephone and a mobile telephone employing the method wherein a volume control button is used to control both a timer setting operation of the mobile telephone as well as the volume of the mobile telephone. When the volume control button is pressed on the mobile telephone, it is determined whether a predetermined amount of time has passed before the volume control button is then released. If the volume control button is held down for at least the predetermined amount of time, the mobile telephone enters a timer setting mode in which a time is entered for activating an alarm. If, on the other hand, the volume control button is pressed and released before the predetermined amount of time has passed, the mobile telephone enters a volume control mode in which the relative strength of the audible signals is controlled.

The illumination control apparatus includes a magnetic field detector for detecting a change in a magnetic field generated by a magnetized ferroelectric object to output a first signal having a voltage which is proportional to the change in the magnetic field; an amplifier for amplifying the first signal; a discriminator for discriminating a level of the amplified voltage to output an illumination on-signal having a first logic level if the level of the amplified voltage is higher than a predetermined voltage, and otherwise to output an illumination off-signal having a second logic level; an illumination controller for outputting an illumination driving voltage in response to the illumination on-signal having the first logic level; and an illumination portion for producing light in response to the illumination driving voltage. Thus, the illumination control apparatus can turn illumination on/off by detecting the approach of a key in any locking system for use in, for example, the front door of a house, cars or office supplies, which requires that the key made of a ferroelectric material is magnetized. Also, the illumination control apparatus can control illumination in response to a specific action of a user and can be easily installed in a limited space.

    摘要: A power control apparatus is provided that receives an input power voltage from a power source and supplies a corresponding output power voltage to a device. The apparatus contains a counter, a processor, and a switch. The counter inputs a power control signal and outputs a count signal that corresponds to a lapsed time from when the power control signal is input. The processor inputs the count signal and outputs a time out signal. The time out signal has a first value if the lapsed time and a predetermined time have a certain relationship, and the time out signal has a second value if the lapsed time and predetermined time do not have the certain relationship. The switch receives the input power voltage from the power source and the time out signal. If the time out signal has the second value, the switch does not output the output power voltage to the device. On the other hand, if the input power voltage is received and the time out signal has the first value, the switch outputs the output power voltage to the device. In addition, a method performed by the power control apparatus is provided.
