SHD4 Video Decoder Board

— H.264 video decoder, high definition output up to 1920*1080@60
— Ethernet input, HDMI+AV output
— Audio codec with audio output
— Video record with a Micro SD card or USB disk
— Web UI or uart for management
— The normal video latency is about 200ms when paired with encoder module
— Support proprietary H.264 video decompression only used p-frames for lowest latency as 50ms to 130ms

SHD4 video decoder board implements H.264 video decoding and audio codec, the video stream input via Ethernet is decoded and sent to display via HDMI and AV interface. The SHD4 decoder board features a range of comprehensive signal outputs including an HD video at 1080P/720P, down-converted HD CVBS monitor video, and two analog audios supported. SHD4 board includes DVR record functionality with a Micro SD card or USB disk using record switch controls. 此外, the SHD4 board supports a built-in RTSP server that enables video streaming over Ethernet for remote software or hardware decoders(选项). This board is in compact size and suitable for embedded applications and real-time live video monitoring via wireless link or Ethernet.
