2-2-3 Detailed Feature
DVD-Video Feature 1When Developing the DVD Software, various addition and modification is possible.
As the storage capacity increases, the DVD-Video separates the main data and the additional data such as the
Multi-Function into different data areas, enabling the control of time-data ratio to provide the format that enables
the flexible Software development
? 1 Movie (3.5Mbps)
+ Subtitle (1 Language)
+ Surround Audio (1 Language)
= 160min storage (4.673Gbytes)
? 1 Movie (3.5Mbps)
+ Subtitle (4 Language)
+ Surround Audio (4 Language)
= 160min storage (4.680Gbytes)
? 1 Music Video (4Mbps)
+ 2ch High quality Audio (96kHz/24bit)
= 72min storage (4.648Gbytes)
DVD-Video Feature 2Application of the MPEG-2 compression technology.
DVD-Video uses the variable compresion technology, the MPEG-2 to compress the moving image optimally, mini-
mizing the Data loss to Provide a clear, natural screen while increasing the storage time.
? MPEG-2 (Variable compression : Max. 1/40)Amount of data
? Field unit compression.
? Compression rate change according to the amount of Data.
DVD-Video
?Differentiates the still image anf the moving image
compression rete, reducing Data loss and enables Time
efficient compression.
Loss area
? MPEG-1 (Fixed compression : Max. 1/140)Amount of data
? Frame unit compression.
? Compresses all data using the same ratio.
