Abstract:
PURPOSE: A system for providing targeting augmented content, a method thereof, a device thereof, a method for registering augmented content, and a device thereof are provided to enable a specific viewer to display desired information to other targeted viewers in a predetermined section of a broadcast program and predetermined time. CONSTITUTION: An augmented metadata generation device generates augmented metadata(S310). A second broadcast terminal analyzes the augmented metadata and requests augmented content to an augmented content providing device based on the augmented metadata(S360,S370). The augmented content providing device transmits the augmented content to the second broadcast terminal(S380). The second broadcast terminal outputs broadcast content provided from a broadcast content providing device and the augmented content(S390).

Abstract:
PURPOSE: A legal monitoring apparatus, monitoring target apparatus, monitoring system, and method thereof are provided to enable a network service provider to instantly monitor a monitoring target by receiving monitoring activation information from the monitoring target through a communication network. CONSTITUTION: When a monitoring target apparatus(102) accesses a new communication network(105) which does not have a legal monitoring right, a communication unit(1090) receives monitoring activation information acquired from the monitoring target apparatus through a communication network which has the legal monitoring right. A monitoring execution unit(1092) successively monitors the monitoring target apparatus by using the received monitoring activation information.

PURPOSE: A string matching method is provided to perform string matching for high speed data streams, thereby increasing efficiency. CONSTITUTION: An input buffer(101) aligns an inputted data stream based on a size to generate a string stream. A delay buffer(102) delays a string of the input buffer by 1 clock. A comparator(105) outputs a detection signal showing detection of sub strings. A chain circuit(106) determines whether a target string is detected. An encoding circuit(107) outputs a string ID corresponding to the detected target string.

PURPOSE: An apparatus and a method for detecting appropriateness of a 8B/10B code group are provided to remove a double process and an additional device for forming a nibble clock by using only byte clocks. CONSTITUTION: An apparatus for detecting appropriateness of a 8B/10B code group includes a 6B/5B disparity sort unit, a 4B/3B disparity sort unit, an RD6 detection unit, an RD4 detection unit, a 8B/10B code rule infraction detection, an RD error detection unit, and an output unit. The 6B/5B disparity sort unit(310) sorts disparity of 6 low-bit nibbles of an 8B/10B code group and outputs the characteristic information thereof. The 4B/3B disparity sort unit(315) sorts the disparity of 4 high-bit nibbles of the 8B/10B code group and outputs the characteristic information thereof. The RD6 detection unit(330) generates the running disparity of the 6 low-bit nibbles of the 8B/10B code group and using the running parity of the 8B/10B code group and the characteristic information of the disparity of 6 low-bit nibbles. The RD4 detection unit(335) generates the running disparity of the 4 high-bit nibbles of the 8B/10B code group by using the running disparity of the 6 low-bit nibbles and the characteristic information of the disparity of 4 high-bit nibbles. The 8B/10B code rule infraction detection(350) detects an infraction of the 8B/10B code group. The RD error detection unit(345) detects an error of the running disparity of the 6 low-bit nibbles and an error of the running disparity of the 4 high-bit nibbles. The output unit outputs the appropriateness of the 8B/10B code group.

PURPOSE: A multi-tone transceiver system is provided to be able to use TEQ(Time-domain Equalizer) efficiently according to characteristic of each band by using VDSL transceiver system on DMT base. CONSTITUTION: The first buffer unit outputs with dividing into each sub-band after storing temporary transmission band of signal coded sequentially . A DMT modulation part outputs signals modulating each sub-band signal from the first buffer unit into multi-carrier. The second buffer unit stores temporary the real number of signal of each sub-band modulated into the multi-carrier. A composition bank of CMFB(520) trans-multiplexor transmits signals from the second buffer unit to frequency division multiplexor channel. A decomposition bank of CMFB(540) trans-multiplexor separates the frequency division multiplexor signal transmitted from the channel into each frequency and divides into the each sub-band signal. The third buffer unit divides the real numbers into the each sub-band after storing temporary the real number of signal divided into each sub-band and outputs the real numbers sequentially. The firth buffer unit outputs original signals of the whole transmission band after storing temporary modulated signal for each the sub-band.
