digital tv headend cctv network video encoder

(our device is reliable quantity with reasonable price)

Outline

The 4 in 1 Encoder is a professional audio & video encoding and multiplexing device with powerful functionality. It has 4 channel CVBS video and 4 pairs of unbalanced audio input interfaces, also, it can support MPEG-2 encoding format, analog composite video and single/ analog stereo audio mode. The output interface of compressed data is ASI, whose condensed method is MEPG-2 MP@ML,This device can simultaneously encode 4 channel audio & video; Moreover, it can multiplex the input TS with the 4 encoded SPTS to generate a MPTS output. In conclusion, its high compatibility and cost effective design are totally comply with MPEG-2 standard, and  the device is widely used in varieties of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV, etc.
