Cov TV Headend MPEG2 rau H. 264 Transcoder

Jul 05, 2016

DIBSYS ENC3580 yog ib tug neeg bidirectional transcoder los siv yees duab ntawm H.264 thiab MPEG-2 hom ntawv thiab kuj tau transcode ntawm cov kev pab cuam HD thiab SD tau ib txhij. Nws yuav nruab muaj 6 DVB-S2/C/T tuner inputs raws tau ncaj qha mus, los yog ASI /IP inputs tau raws cov. Tom qab transcoding, nws outputs MPTS & SPTS los ntawm qhov chaw nres nkoj tus IP tej ntaub ntawv los sis ASI. Ib tug ntawm cov yam ntxwv tseem ceeb ntawm kev ENC3580 yog kev HD-rau-SD os Converting, ua lub community launch txog txhais kev pab cuam, xws li ib tagnrho-HD tawm rau SD lineup yooj yooj yim thiab nqe zoo. Feature ntawm ENC3580 koj yog hais tias nws yuav transcode HD/SD H.264 los MPEG-2, thiaj li yooj yim rau phlis H.264 Pib ntsais koj teeb satellite ua luaj rau kom raug nyiaj tsawg MPEG-2 daim ntawv lawv.

No transcoder kev txhawb zog siab heev rov multiplexing thiab ua zoo muab tswv nrog real-time chaws twg hloov thiab optimize tus yees duab nrog nws txoj kev kawm ntawv siab. BISS muaj nuj nqi tam sim no kos rau descramble koj tuner input cov kev pab cuam thiab kev zov menyuam zoo thiab coj tau koj kaw npe duab (los yog teletext). Nws yuav yooj yim tswj los ntawm lawv lub WEB NMS, thiab kuj yog ib qho muab zoo tagnrho rau tus neeg teb xov tooj ntawv zoo video trans-coding.
