摘要： A class library footprint file for authenticating a dynamically loaded class library during the execution of a JAVA application and a JAVA application authentication method using the class library footprint file are provided. The class library footprint file includes: authentication information for verifying the integrity of one or more class libraries used by the JAVA application before the JAVA application is executed. A list of class libraries to be authenticated is provided, in advance, to a JAVA application.

摘要： A trellis encoding device includes a plurality of trellis encoders to perform trellis-encoding of a transport stream into which a supplementary reference signal (SRS) has been inserted, and performs a memory reset in a region that precedes an SRS; and a parity compensation unit to compensate for parities of the transport stream in accordance with values stored in memories included in the trellis encoders. The plurality of trellis encoders may be implemented in diverse types. The trellis encoding device can perform a memory reset selectively using the stored value of the memory and the inverted value thereof, or selectively using the stored value of the memory and a fixed value. By properly resetting the memory in processing the transport stream into which the SRS has been inserted, DC offset can be reduced.

摘要： A digital broadcasting transmission and/or reception system having an improved reception performance and a signal-processing method thereof. A digital broadcasting transmitter comprises a TRS encoder for to TRS-encode an MPEG-2 transmission stream having null data for inserting an SRS data and a TRS parity at predetermined positions, randomizer to input and randomize data stream from the TRS encoder, a SRS exchanger to replace the null data for inserting the SRS data to the known data, and an encoder for encoding a data streams to which the Known data is inserted. Accordingly, the present invention detects the known data from a signal received from a reception side and uses the detected known data for synchronization and equalization and further uses the TRS parity for correcting error of the received signal, so that the digital broadcasting reception performance can be improved at poor multipath channels.
