EN8130 SD H.264 Video Encoding
Inputs
SDI Input via 75 ohm BNC connector.
Digital Audio Input via 15 way D-Type connector
Overview
The EN8130 SD H.264 VCM can encode one standard definition video input.
The video input signal is processed in to a compressed encoded bit-stream in accordance with the H.264 specification (ITU-T H.264
or ISO/IEC MPEG4 AVC).
A constant bit rate (CBR) output can be produced and may be set to between 0.5Mbps and 12.5 Mbps, depending upon the
configured encoding profile. The card can also produce a variable bit rate output when operating as part of a Reflex statistical
multiplexing system.
Video Compression Functionality
The following is a summary of the Video Compression functionality available from the EN8190 HD H.264 VCM.
Test Patterns
The video pre-processor has the facility to generate a
test pattern
.
Loss of Video Input
On loss of video input, the SD H.264 VCM can be configured to select one of the default
test patterns
or a freeze frame as the
output. It is also possible to configure it to stop generating the compressed video component on loss of the video input.
Impairment Reduction
The video pre-processor provides spatial/temporal noise reduction which is motion adaptive.
