EM2838XD is an H.264 hardware compression capture solution that supports BT1120 digital video interface input. The chip is equipped with a built-in hardware encoder to complete video compression, which does not occupy any CPU resources of the host. It can capture multi-source videos such as BT1120/HDMI/CVBS into H.264 video streams and is widely used in monitoring DVR recording and multi-channel video capture scenarios.

Core Features:

• Video input: BT1120 digital video interface (16 bit YCbCr 4:2:2)
• Transfer support: HDMI/CVBS input can be expanded through external HDMI Rx or Video ADC
• Hardware Encoding: The chip is equipped with an H.264 hardware encoder, pure hardware compression, and zero CPU usage
• Encoding parameters: Bitrate adjustable (1Mbps -20Mbps), GOP/I/P frame configurable
• Output format: Standard H.264 TS stream, can directly save video or stream
• Output interface: USB 2.0 High Speed, UVC/UAC drive free
• Multi channel expansion: supports 4-channel DVR acquisition card solution, single-chip multi-channel encoding

Advantages of the solution:

• Real hardware encoding, does not occupy host CPU resources, low power consumption, long battery life
• H. 264 TS standard streaming format, directly compatible with general-purpose players and NVR systems
• The BT1120 interface can be directly connected to SOC Sensor modules, eliminating the need for intermediate conversion chips

Typical application:

• Monitoring DVR/NVR Video Recorder
• 4-channel BT1120 video capture card
• CVBS/HDMI to H.264 video encoder
• Vehicle mounted driving recorder DVR solution
• Remote video surveillance streaming encoder
