Abstract: An apparatus for multi-standard Intra prediction decoding in a video decoder for decoding two video streams coded in two different video coding standards is disclosed. The apparatus comprises a first Intra prediction decoder to decode a first bitstream comprising one or more first Intra prediction coded blocks, and a second Intra prediction decoder to decode a second bitstream comprising one or more second Intra prediction coded blocks. The first Intra prediction coded blocks are coded according to a first video coding standard and the second Intra prediction coded blocks are coded according to a second video coding standard. The first Intra prediction decoder and the second Intra prediction decoder are arranged to perform Intra prediction decoding on the two video streams simultaneously by decoding the two video streams in an interleaved manner at a picture level, slice level, or largest coding unit (LCU)/macroblock (MB) level.
