Abstract: A method for inferring and estimating a wireless channel state using an observation parameter and a method for inducing a bit error rate/parameter inference model are provided to improve the error recovery by inferring and estimating the bit error rate of a reception data packet by using an observation parameter. An observation parameter for estimating a channel state is determined from one data packet received through a wireless channel(400). A BER(Bit Error Rate) for the reception data packet based on the determined observation parameter is estimated(406). The estimated BER is fed back to a transmission side.

Abstract: A system and a method for tracking gaze are provided to increase the accuracy of small and inexpensive equipment, and respond to vertical movement of a user pupil sensitively in a terminal equipped with a display device. An image obtaining module(100) obtains a user eye image refracted to 45 angular degrees by irradiating infrared to the eyes of a user and refracting the lighted user eye image to 45 angular degrees. An image processing module(210) obtains a central point of the pupil in the user eye image by operating a selected algorithm and maps the central point of the pupil to a display screen plane of a display device(300) through a predetermined conversion function. The image obtaining module includes an infrared lighting unit(110) irradiating the infrared to the eyes, an infrared refractor(120) refracting the eye image lighted by the infrared, and a small camera(130) capturing the eye image refracted to 45 angular degrees.

Abstract: PURPOSE: An apparatus and method for protecting constituent elements of a digital broadcasting program using an MPEG-4 system are provided to control illegal access to various contents to be provided in a digital broadcasting environment. CONSTITUTION: An apparatus for protecting constituent elements of a digital broadcasting program includes a transport stream analyzer(100), a data generator(300), a multiplexer(500), and a controller(400). The transport stream analyzer analyzes a transport stream including the constituent elements to extract a corresponding program map table. The data generator generates an intellectual property management and protection descriptor for protecting the program constituent elements, an object descriptor for connecting the IPMP descriptor with a specific interval of the program constituent elements, and a new program map table that is connectable with the object descriptor. The multiplexer multiplexes a transport stream including a corrected program map table, the IPMP descriptor and object descriptor generated by the data generator. The controller controls the transport stream analyzer, data generator and multiplexer.

Abstract: Disclosed is a program recommendation system and method which receive PSIP/SI and programming information on digital broadcasting and provide a program recommendation service to viewers in an EPG application. The system receives personal information in order to set information of each viewer, confirms the received PSIP/SI information, and generates watching information through a viewer watching TV, in a predetermined format. In addition, the system inputs the generated watching information to a database, converts watching information of each viewer which is stored in the database input unit into divided input patterns using a fuzzy membership function to analyze the input patterns, and extracts information on a program with a high degree of preference from the analyzed result. Furthermore the system outputs preference program information of each viewer on a screen in order to recommend a program.
