Spatial information associated with an audio signal is encoded into a bitstream, which can be transmitted to a decoder or recorded to a storage media. The bitstream can include different syntax related to time, frequency and spatial domains. In some embodiments, the bitstream includes one or more data structures (e.g., frames) that contain ordered sets of slots for which parameters can be applied. The data structures can be fixed or variable. The data structure can include position information that can be used by a decoder to identify the correct slot for which a given parameter set is applied. The slot position information can be encoded with either a fixed number of bits or a variable number of bits based on the data structure type.

Provided are an apparatus, system and method for detecting malicious code inserted into a normal process in disguise. The apparatus includes a malicious code detection module for extracting information on a thread generated by a process running on a computer system to identify code related to the thread, preliminarily determining whether or not the identified code is malicious and extracting the code preliminarily determined to be malicious; and a forcible malicious code termination module for finally determining the code as malicious code based on an analysis result of behavior of the extracted code executed in a virtual environment and forcibly terminating execution of the code.

Provided are a virtual server and method for identifying a zombie, and a sinkhole server and method for integratedly managing zombie information. The virtual server includes an authentication processing module authenticating a host using a CAPTCHA test and providing a cookie to the authenticated host when a web server access request message received from the host does not include a cookie, a cookie value verification module for extracting a cookie value from the web server access request message and verifying the extracted cookie value when the web server access request message includes a cookie, a web page access inducement module for inducing the host to access a web server when the cookie value is verified, and a zombie identification module for blocking access of the host when the cookie value is not verified, and identifying the host as a zombie when the number of blocking operations exceeds a threshold value.

Methods and apparatuses for encoding and decoding a multi-channel audio signal are provided. In the encoding method, spatial information is calculated based on a multi-channel audio signal and a down-mix signal, and a compensation parameter that compensates for the down-mix signal is calculated based on the multi-channel audio signal and the down-mix signal. Thereafter, a bitstream is generated by encoding the spatial information, the compensation parameter, and the down-mix signal and combining the results of the encoding. Therefore, it is possible to prevent deterioration of the quality of sound regarding a multi-channel audio signal by compensating for the multi-channel audio signal using a compensation parameter that compensates for a down-mix signal.

The invention relates to a method for decoding an audio signal, to allow an audio signal to be compressed and transferred more efficiently. The inventive method comprises steps of receiving an audio signal with spatial information signal, obtaining location information using the number of time slot and parameter of audio signal, establishing a multi-channel audio signal by applying spatial information signal to down-mix signal, and performing a multi-channel array for a multi-channel audio signal in response to the output channel.
