Introductions Integrated with MPEG-2 and MPEG-4 AVC/H.264 compression formats, RES2308 MPEG-2/H.264 Four-Channel SD Encoder realizes multi-function and powerful operations of SD encoders. Flexible designs and configurations of inputs, 8*CVBS, 8*SD-SDI, and 2*CVBS+2*SD-SDI, provides more options for diversified applications in a cost-effective way. The device supports MPEG-1 Layer II, LC-AAC and HE-AAC audio compression formats, with 8*unbalanced stereo LR or 8*SD-SDI embedded or 2*unbalanced stereo LR+2*SD-SDI for options. RES2308 offers an additional ASI input interface, making input local programs to be multiplexed with its SPTS or MPTS signals. This feature makes it more powerful, functional and not only limited as an encoder. RES2308 performs well in ultra-low bit rate and low latency for each channel. The device outputs with ASI and TSoIP(in 1*MPTS or 4*SPTS, UDP protocol), to meet variety of needs in digital TV industry, such as IPTV, DTV broadcasting head-end systems, and so on. Diagram
