Frequently Asked Question
What does encode parameter VFORMAT De-interlace mean?
Using de-interlace mode improves compression efficiency by 40% to 50%. In de-interlace mode, two consecutive fields are compressed together. In non-de-interlaced mode, each field is compressed individually.
De-interlaced mode is useful for network applications or low bandwidth applications where encode and decode are performed by the ADV2x2.
VFORMAT de-interlace can be used for NTSC or PAL.
In decode, de-interlace mode is only a valid decode mode if the compressed input codestream is a previously encoded ADV2x2 codestream that has been encoded with VFORMAT set to de-interlaced.
