MICROCHIP H.264 encoder

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 yees duab uas lub block loj yog txhais li 16 x 16 thiab 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 thiab P ncej compression muaj plaub stages:

• Intra / Inter twv ua ntej
• Integer transformation
• Quantization
• Entropy encoding

H. 264 txhawb nqa ob hom kev encoding:

• Context Adaptive Variable Length Coding (CAVLC)
• Context Adaptive Binary Arithmetic Coding (CABAC)

Tam sim no version ntawm H.264 Encoder siv lub hauv paus profile thiab siv CAVLC rau entropy encoding. Tsis tas li ntawd, H.264 Encoder txhawb kev encoding ntawm I thiab P ntas.

Hardware Implementation

Tshooj lus no piav qhia txog qhov sib txawv sab hauv modules ntawm H.264 Encoder. Cov ntaub ntawv nkag mus rau H.264 Encoder yuav tsum nyob rau hauv daim ntawv ntawm raster scan duab hauv YCbCr 422 hom. H.264 Encoder siv 422 hom ntawv raws li cov tswv yim thiab siv compression hauv 420 hom.
Daim duab hauv qab no qhia txog H.264 Encoder thaiv daim duab.

Daim duab 1-1. H.264 Encoder – Modules

1. Intra Prediction
   H.264 siv ntau hom intra-prediction los txo cov ntaub ntawv hauv 4 x 4 thaiv. Qhov thaiv kev twv ua ntej hauv IP tsuas yog siv DC kev twv ua ntej ntawm 4 x 4 matrix loj. Lub DC tivthaiv yog xam los ntawm sab saum toj uas nyob ib sab thiab sab laug 4 x 4 blocks.
2. Integer Transform
   H.264 siv integer discrete cosine transform qhov twg cov coefficients raug faib thoob plaws lub integer transform matrix thiab cov quantization matrix xws li tias tsis muaj kev sib faib los yog sib faib hauv cov integer transform. Lub integer transform stage siv qhov kev hloov pauv siv hloov pauv thiab ntxiv cov haujlwm.
3. Quantization
   Lub quantization multiplies txhua qhov tso zis ntawm integer transform nrog ib tug predetermined quantization tus nqi txhais los ntawm QP tus neeg siv input tus nqi. Qhov ntau ntawm QP tus nqi yog los ntawm 0 txog 51. Txhua tus nqi ntau dua 51 yog clamped rau 51. QP tus nqi qis dua qhia tias qis compression thiab zoo dua thiab rov ua dua.
4. Motion kwv yees
   Qhov Kev Ntsuas Ntsuas Ntsuas 8 x 8 thaiv ntawm cov ncej tam sim no hauv 16 x 16 thaiv ntawm tus ncej dhau los thiab tsim cov duab vectors.
5. Motion Compensation
   Motion them nyiaj tau txais cov lus tsa suab vectors los ntawm Motion Estimation block thiab pom qhov sib thooj 8 x 8 block hauv tus ncej dhau los.
6. CAVLC
   H.264 siv ob hom entropy encoding-CAVLC thiab CABAC. Tus IP siv CAVLC rau encoding cov zis ntau.
7. Header Generator
   Lub header generator block tsim cov block headers, cov hlais headers, Sequence Parameter Set (SPS), Daim Duab Parameter Set (PPS), thiab Network Abstraction Layer (NAL) chav nyob nyob ntawm qhov piv txwv ntawm video thav duab. Hla thaiv kev txiav txim siab logic suav qhov Sum ntawm Qhov Tsis Txaus Siab (SAD) ntawm cov ncej tam sim no 16 x 16 macro thaiv thiab yav dhau los ncej 16 x 16 macro thaiv los ntawm cov lus tsa suab vector kwv yees qhov chaw. Kev hla thaiv yog txiav txim siab siv tus nqi SAD thiab SKIP_THRESHOLD cov tswv yim.
