H264 COFDM Receiver Module
– 160MHz ~ 860MHz HD kanema COFDM wolandila gawo ndi HDMI/AV/Efaneti/USB linanena bungwe
– H.264 video decoder
This COFDM receiver module is a compact digital diversity receiver with integrated H.264 decoding, oyenera kugwiritsidwa ntchito pamadzimadzi komanso kuyenda kwambiri. Ma module olandila amalandila ma siginecha kuchokera ku tinyanga ziwiri kuti apititse patsogolo magwiridwe antchito ndikuwonjezera magwiridwe antchito. Ma module olandila amatha kupeza ndikutseka basi kumayendedwe omwe akubwera mwachangu malinga ndi ma frequency omwe adakhazikitsidwa kale ndi bandwidth.. Module yolandila iyi imakhala ndi zotulutsa zambiri zama siginecha kuphatikiza HD pa 720p ndi 1080P, pansi-otembenuzidwa HD CVBS polojekiti kanema, and two analog audios is supported.
The receiver module also includes DVR record functionality with Micro SD card or USB disk. Kuphatikiza apo, the receiver module has a built-in RTSP sever that enables video streaming over Ethernet for remote software or hardware decoders. And the receiver module also enables video streaming over USB for remote Android device decoders like Smart phone or Android PAD. Izi zimalola owonera angapo akutali kuti azitha kuyang'anira kanema yemweyo nthawi imodzi. Gawo lolandila limathandiziranso zingwe zowonetsera pazithunzi zowonetsera kanema ndi kanema palimodzi mumayendedwe a OSD.
When paired with the COFDM transmitter module, module yolandila imapereka zambiri, mavidiyo ndi ma audio omwe amatha kutumizidwa mwachangu omwe amathandizira kuzindikira kwanthawi yayitali. Itha kukhala ndi gawo lofunikira popereka makanema apanthawi yeniyeni kuchokera pamapulatifomu am'manja komanso owulutsa ndege.
- Kutsitsa kwa COFDM ndi decoder ya kanema ya H.264
- Full HD resolution, 1080P@60fps
- Chitetezo chachikulu ndi AES decryption
- DVR kujambula ndi Micro SD khadi kapena USB litayamba
- Seva yomangidwira ya RTSP imathandizira kuti makanema aziyenda pa Ethernet
- Enables video streaming over USB host for remote device
- Imathandizira zingwe zowonetsera pazithunzi zowonetsera kanema mumachitidwe a OSD
- Kusamutsa kwazizindikiro kokhazikika mu NLOS komanso kuthamanga kwambiri
- Ma frequency osinthika ogwirira ntchito, band width
Wophatikizidwa ndi COFDM transmitter
This module can also be paired with SUE5&RCB transmitter module(or SUE5SA&RCB module) for lowest video latency application when manufactured with specified firmware. The specified firmware enable proprietary H.264 video compression/decompression only used p-frames for lowest latency. Kanemayo latency kuchokera pakuyika kwake kwa transmitter kupita ku HDMI kuwonetsa wolandila ndi pafupifupi 50ms mpaka 130ms..
