Product Description

4 HD-SDI to QAM DVB-C Encoder Modulator

H.264 SDI to RF Encodulator   Model: COL5011U-4SC                    




This 4/8CH SDI Encodulator is a professional HD and SD audio & video encoding and multiplexing device with powerful functionality. It has 4/8 channel SDI input interfaces, supporting MPEG4AVC/H.264 High Profile code format. This device can simultaneously encode 4/8 channel HD programs; moreover, it has an ASI input and can multiplex the input TS with the 4/8 encoded SPTS to generate a MPTS output. Also, the PSI/SI information can be inserted into MPTS output. In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
