Introduction: The high-definition code modulation and all-in-one machine is a newly developed high-performance device that integrates high-definition encoding and modulation. The device supports 8 channels / 12 channels HDMI input, 1 channel Gigabit IP input + 1 channel 100 Mbps IP input; supports 4 DTMB single carrier output or 4 MPTS output. The device is characterized by high integration, high performance and low cost. The single device integrates a set of front-end system functions, which is very suitable for digital TV systems such as hotels, clubs, hospitals and baths. Features: 1. Support 8 / 12 HDMI input, MPEG-4 AVC / H.264 high / SD encoding 2. Support MPEG-1 Layer 2 audio encoding format 3. Support 1 channel Gigabit, 1 channel 100M IP input, 128 IP addresses, UDP, RTP protocol 4. Support 4 DTMB carrier outputs 5. Support 4 MPTS outputs (DATA1), UDP, RTP protocol 6.
