Microchip PolarFire® FPGA H.264 Encoder IP Tus Neeg Siv Qhia
Taw qhia
H.264 yog tus qauv nrov video compression rau compression ntawm cov yees duab digital. Nws tseem hu ua MPEG-4 Part10 lossis Advanced Video Coding (MPEG-4 AVC). H.264 siv block wise mus kom ze rau compressing cov yeeb yaj duab uas lub block loj yog txhais raws li 16 × 16 thiab xws li block yog hu ua macro block. Tus qauv compression txhawb ntau yam profiles uas txhais cov compression ratio thiab complexity ntawm kev siv. Cov video thav duab yuav tsum tau compressed yog kho raws li kuv ncej, P ncej thiab B ncej. Ib qho I thav duab yog ib qho intra-coded thav duab uas compression yog ua los ntawm kev siv cov ntaub ntawv muaj nyob rau hauv tus ncej. Tsis muaj lwm cov thav duab yuav tsum tau txiav txim siab rau tus ncej I. AP thav duab yog compressed los ntawm kev siv cov kev hloov pauv nrog rau cov ncej ua ntej uas tuaj yeem yog I ncej lossis P ncej. Lub compression ntawm B thav duab yog ua los ntawm kev siv cov kev hloov pauv nrog kev hwm rau ob qho tib si ua ntej thiab cov ncej tom ntej.
Cov txheej txheem I ncej compression muaj plaub stages-Intra twv ua ntej, Integer transformation, Quantization thiab Entropy encoding. H.264 txhawb nqa ob hom kev encoding—Context Adaptive Variable Length Coding (CAVLC) thiab Context Adaptive Binary Arithmetic Coding (CABAC). Tus IP version tam sim no siv Baseline profile thiab siv CAVLC rau entropy encoding. Tsis tas li ntawd, tus IP txhawb nqa encoding ntawm kuv tus ncej xwb.
