摘要

The present invention relates to an image information encoding and decoding method and a device for same. One embodiment of an image information encoding method according to the present invention, as an image information encoding method according to another embodiment of the present invention, includes the steps of: generating a restore block; applying a deblocking filter on the restore block; applying a Sample Adaptive Offset (SAO) on the restore block having the deblocking filter applied thereon; and transmitting information on the SAO application. During the applying of the SAO, the SAO is applied to chroma pixels, and during the transmitting of the information, in addition to information on whether the SAO is applied on the chroma pixels, at least one of area information, division information on the SAO coverage area, SAO type information, and SAO offset information is transmitted.

說明書

}

When an SAO parameter is indicated using the slice header syntax, parameters necessary for applying the SAO are transmitted over the SAO parameter syntax. The parameters to be transmitted include sao_split_param related to division of the SAO application region and sao_offset_param related to an offset to be applied in the SAO, as in the example shown in Table 4.

In the example shown in Table 4, when the value of sao_flag is 1, it means that the SAO can be applied (enabled) to at least a part of a current picture. When the value of sao_flag is 0, it means that the SAO cannot be applied (disabled) to the entire current picture. Therefore, when the value of sao_flag is 1, the SAO parameters may be indicated.

Table 5 schematically shows an example of a sao_split_param related to division out of the SAO parameters as a syntax structure for applying the SAO.
