18565250908Product Overview
The integrated encoder integrates MPEG-2 encoding and DVB-T/C/DTMB/ATSC/ISDB-T modulation functions; Support HDMI signal input; It can accept signals from various sources, such as satellite receivers, CCTV cameras, Blu ray players, and other devices. After encoding and modulation, the input signal can be directly output or mixed with the original closed circuit television signal for output. The RF output signal can be received by DVB-T/C/DTMB/ATSC/ISDB-T standard televisions or set-top boxes, and real-time audio/video playback can be achieved. In the television distribution system, this device can be widely used in places such as home entertainment, security monitoring, hotel signage, and mall advertising.
1. Support MPEG-2 video encoding
2. Support MPEG1 Layer II, AAC,AC3
3. Integrating encoding and modulation functions
4. Supports two video modes, VBR
5. Support CC、LCN
