What’s SKD121X Encoding & multiplexing modulator? Introduction SKD121X is a device that combines encoding, multiplexing and modulation. 12 channels of HD or SD input, one RF and one IP output. Easy operation, intelligent functions such as alarm system, parameter import and export, and abnormal reminder. The left side of the chassis is equipped with a server-level cooling fan, automatic temperature control to adjust the speed ,extend the life of the fan while ensuring normal heat dissipation. Characteristics 12 HDMI or AV input Optional MEPG2 or H.264 encoding Synchronous RF and IP output DVBC（J.83A、J.83B）、DVB-T output No complicated system settings, just adjust the frequency to the required, simplify system debugging PC or Smartphone app operation 3 temperature control fan powerful cooling Technical Parameters Encoding parameters HDMI (1.4a) encoding Video Encoding standard Resolution H.264 1920*1080_60P,1920*1080_50P;1920*1080_60i, 1920*1080_50i;1280*720_60p, 1280*720_50P 1-19.5Mbps Bit rate Audio Encoding standard Sampling Rate Bit rate MPEG1 Layer II AAC 48KHZ/44.1KHZ/32KHZ 384kbps Programmable program name, pmt PID, Video PID, Audio PID PSIP MGT、CVCT、STT、RTT Modulation parameters J.83A Modulation standard Annex A Constellation MER RF frequency range 64QAM, 256QAM ≥40dB 50 – 1000 MHz stepping 1KHz ≥105dBuV range 0-20dB ， stepping 0.5dB） Minimum Output electrical level （ Adjustment
