Title: Methode for processing slave device event in device link system based television
Inventor: IM KANG HEE
IPC: H04N5/44
Filed: 2005-05-10
Abstract: A method of processing a slave device event in a device link system based on television is provided to connect slave devices to a master device using stereo jacks in a daisy chain manner and allow the master device to control the operations of the slave devices. A request message corresponding to an event generated in a slave device is generated when the event is generated in the slave device in a television-based device link system, and the request message is transmitted to a master device. The master device receives the request message, confirms the event, and performs an event processing operation corresponding to the event. The slave device waits until the communication state of the master device becomes an idle state when a local event is generated by a user's key operation, and then transmits a request message corresponding to the event. The master device confirms the event, automatically switches an input mode to the slave device when the event corresponds to initiation of reproduction, generates a request message for turning off power of a specific device that is operating before the event is generated and outputs the request message to the specific device.

Title: Method of ultra-fine bit count control of video frame
Inventor: PARK KYU HO
IPC: H04N19/124
Filed: 2005-05-23
Abstract: A method for precisely controlling a bit count of a moving picture frame is provided to adaptively select the positions and the number of macro-blocks and control a quantization parameter of the macro-blocks to rapidly and correctly make a generated bit count of a compressed frame correspond to a target bit count. A generated bit count of a compressed frame is compared to a target bit count. When the generated bit count is greater than the target bit count(S100), the quantization parameter of predetermined macro-blocks is increased to reduce the generated bit count such that the generated bit count approximates the target bit count(S200). When the generated bit count and the target bit count have not been changed even though the generated bit count is reduced, the number of macro-blocks is increased and the quantization parameter of the macro-blocks is increased to decrease the generated bit count such that the generated bit count approximates the target bit count. When the generated bit count is smaller than the target bit count, the quantization parameter of predetermined macro-blocks is reduced to increase the generated bit count such that the generated bit count approximates the target bit count(S300). When the generated bit count and the target bit count have not been changed even though the generated bit count is increased, the number of macro-blocks is increased and their quantization parameter is reduced to increase the generated bit count such that the generated bit count further approximates the target bit count.

The first LNA(202) cancels a noise from a signal filtered through the first duplexer(200). The first splitter(204) splits an output signal of the first LNA(202) into two. The first BPF(206) extracts only a valid signal from the first output signal of the first splitter(204). The first amplifier(208) amplifies an output signal of the first BPF(206). The first mixer(210) combines an output signal of the first amplifier(208) with an output signal of the first PLL(Phase Locked Loop)(212). The first noise attenuator(214) cancels a noise from an output signal of the first mixer(210). The first HPA(216) receives an output signal of the first noise attenuator(214) through the first switch(312) and performs linear high-power amplification for the received signal.
