Abstract: A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.

Abstract: Disclosed are methods and apparatuses for compressing and decompressing data at a sample rate lower than a Nyquist sampling rate for the data. The data compression apparatus comprises a domain converting part performing a domain conversion on input data to generate domain-converted input data, and a data compression part generating compressed data by down-sampling the domain-converted input data at a sampling rate lower than a Nyquist sampling rate. Therefore, data to be transmitted can be compressed in a transmitting end by sampling the data at a sampling rate lower than a Nyquist sampling rate, and then the data can be reproduced in a receiving end. Therefore, a higher compression ratio can be achieved as compared with that of conventional technologies.
