Best Practices for At-Home Solutions
A typical AHP includes two or more cameras with LiveU field encoders (LU200/LU300/LU500/LU600) and typically the same number of LU2000 receiver/server output ports back in your Production Control Room (PCR). There is no limit to how many field encoders you can deploy with this solution. As with the field encoders, there’s no limit to the number of receiver/servers that can be deployed as long as the facility has adequate bandwidth available (Depending on unit – 5 to 8 Mbps per camera source). Back at the PCR, the LiveU receiver/servers provide synchronized SDI, NDI or MPEG-TS output(s).
