An encoder/modulator is a device for generating digital TV channels (multiplexer) that contain audio and video services generated by other devices such as cameras, computers, TVSAT receivers, etc. The encoder/modulator Ref.563852 also offers the function of generating a multicast stream. The device has two operating modes: AV-IR/RF encoder - converts two audio/video signals into an IP stream and simultaneously into an RF multistream (DVB-T or DVB-C). In this mode, the audio/video content in HDMI format is available through components (YPbPr) or as composite video (CVBS) in the form of a multicast stream in their output IP and additionally as RF multistream (DVB-T or DVB-C).
