Description

Overview

YDS8808EM Series Multi-Channel H.264 HD Encoder Modulator features high performance, ultra-low latency and low bit rates for DTV systems, and adopts state-of-the-art compression technology (H.264/AVC) to achieve compression efficiency of the former MPEG-2 standard by over two times, as well as excellent resolution.

YDS8808EM Encoder Modulator is the preferred device for content source encoding of DTV broadcasting system to address the ever-increasing demand for more premium viewing experiences. It is a cost-effective device newly developed by our company that integrates The device supports 8 HDMI input, 1 Gigabit IP input/output; supports 4 single carrier (ATSC, ISDBT, DTMBT, DVB-C/-T) output and MPTS output and SPTS output. Support OSD function, can insert subtitles, station logo, QR code, etc. Features high integration, high performance and low cost It has the characteristics of high integration, high performance and low cost. A single device integrates a set of front-end system functions, which is very suitable for digital TV transmission systems such as hotels, clubs, hospitals, and baths.
