The loudspeaker is stated in Claim 4 where the actual data of the program's loudness will be. Part of the field indicating the combined loudness of the audio program without any gain adjustment caused by dynamic range compression 1 0. Loudness Processor is specified in claim 4. Where the actual data of the program's loudness will have Section is a field indicating loudness that is combined into one unit of the audio program without any gain adjustment due to the adjustment of the dialogue section to the interval 1. 1. The loudness processor is specified in clause. Holds 4 rights where the audio processor is configured to Perform adaptive loudness processing using the actual program loudness data 1 2. The loudness processor is specified in one of the 1-11 claims. Where the bit stream of the encoded audio Will it be an AC-3 bit stream or an E-AC-3 bit stream? 1. 3.
