H.264 Video Compression

Txhawm rau txhim kho peb cov neeg muas zaub ib qho kev siv tshaj plaw, Tenveo yuav ntxiv H.264 video compression technology.

Tenveo's USB2.0 Tag nrho HD series yuav txais H.264.

Thaum peb tham txog H.264, tibneeg tsis totaub txog qhov ntawd. H.264 yog dab tsi? Dab tsi yog qhov zoo ntawm H.264?

Hauv qab no yog cov lus qhia ntawm H.264, peb ntseeg koj yuav nkag siab nws tom qab koj nyeem cov ntsiab lus.

H.264 yog dab tsi?

H.264 lossis MPEG-4 AVC (Advanced Video Coding) yog hom video coding rau kev teev cia thiab faib tag nrho HD video thiab suab. Nws tau tsim thiab tswj los ntawm ITU-T Video Coding Experts Group (VCEG) nrog rau ISO / IEC JTC1 Tsiv Daim Qauv Kws Tshaj Lij (MPEG).

Feem ntau yog siv rau kev kaw lus, kev sib txuam, thiab kev faib tawm cov ntsiab lus yees duab, H.264 hom ntawv yog kev sib txuas lus hauv kev sib txuas lus uas xa cov duab zoo uas tsis muaj bandwidth phuam.

Dab tsi yog daim ntawv thov H.264?

H.264 video compression hom yog zoo meej rau AV faib rau ib los yog ntau dua video sources (multicasting ntws rau ntau yam lus). Nws siv tau tshwj xeeb txaus kom ntev-kis kis ntawm cov teeb meem siv cov xov tooj cua thiab cov khoom qub. Nws yog yoo ua qhov qauv video compression hom rau kev yees duab ntiaj teb saib, piv txwv.

Nws cov kev siv tau los ntawm sab nraud broadcast (OB vans), lub zog sector, kev kawm, tsheb thauj mus los yeeb yaj kiab video rau kev saib xyuas kev siv raws li Video Wall Processing , Digital Signage Solutions thiab video conferencing.

Dab tsi yog qhov txiaj ntsim ntawm H.264?

• Tsawg cov kev pab cuam bandwidth thiab kev daws teeb meem dua.
  H.264 raug tsim los muab kev tshaj tawm zoo rau kev yees duab tho yeeb yaj kiab nrog cov kev cai txo qis dua thiab qis dua cov qauv qis dua, xws li MPEG-2. H.264 siv tus codec zoo heev uas muab cov duab zoo tshaj plaws thiab siv tus nqi tsawg ntawm bandwidth.

• H.264 bitrate yog qis dua lwm hom ntawv
  H.264 muaj ib qho 80% tsawg dua ntawm kev tshaj suab Motion JPEG. Nws tau kwv yees tias qhov kev khaws nyiaj cia me ntsis yuav ua tau li 50% los yog ntau tshaj piv rau MPEG-2. Piv txwv li, H.264 muaj peev xwm muab cov duab zoo dua qub rau tib lub ntsis compressed. Ntawm qis tus nqi qis, nws muab cov duab zoo tib yam.

• Txo cov xav tau kev yees duab cia
  H.264 siv qhov ceev cia tsawg dua los khaws video nrog rau lwm cov qauv uas yog qhov tseem ceeb los ua kom yooj yim video sib kis tau los ntawm IP

• Vendor agnostic video extension kua
  Vim hais tias H.264 video yog cov qauv-raws li, nws muab ib qho khoom muag vijor agnostic video extension. Cov neeg siv yuav sib xyaw thiab ua si H.264 cov khoom siv los ntawm cov neeg muag khoom sib txawv tsis muaj kev txhawj xeeb txog kev sib haum xeeb lossis cov teeb meem tshwj xeeb.
