Title: Method and apparatus for processing an audio signal
Inventor: PANG HEE SUCK
IPC: H03M7/30
Filed: 2007-02-16
Abstract: A method and an apparatus for processing an audio signal are provided to improve sound quality of the audio signal by reducing an amount of operations by decoding an expansion signal selectively. A downmixing unit(10) generates a downmix signal by downmixing a multi source audio signal. A downmix signal encoding unit(20) encodes the downmix signal. An ancillary signal encoding unit(30) encodes an ancillary signal. An expansion signal encoding unit(40) encodes an expansion signal. The encoded signals are transmitted to a multiplexer(50). The multiplexer generates a bit stream by multiplexing the downmix signal, the ancillary signal, and the expansion signal. The generated bit stream is transmitted to a decoding device. A demultiplexer(60) receives the bit stream and divides the downmix signal encoded from the bit stream, the encoded ancillary signal, and the encoded expansion signal. A downmix signal decoding unit(70) decodes the encoded downmix signal. An ancillary signal decoding unit(80) decodes the encoded ancillary signal. An expansion signal decoding unit(90) selectively decodes the encoded expansion signal. An upmixing unit(100) generates an audio signal by using the ancillary signal.

Title: Partial duplicate and encryption for packets, and decryption
Inventor: UNGER ROBERT ALLAN
IPC: H04L9/16
Filed: 2002-12-13
Abstract: An encryption arrangement for multiple encryption of television programs. A system according to embodiments of the present invention multiple encrypts only a portion of the data required for full presentation of a television program to permit multiple manufacturer's set-top boxes (36 and 136) within a single system. In one embodiment, only critical packets such as those carrying a payload incorporating packetized elementary stream header information is encrypted. By only encrypting a portion of the program, dramatically less bandwidth is consumed than the alternative of multiple encryption of all program data, thus permitting a larger number of multiple conditional access systems in a single cable television system. ® KIPO & WIPO 2009
