Overview:
OTV-EP25 Multi-Channel HD Encoder with H.264/H.265 video encoding mode by default, H.265 high compression ratio can help to save bandwidth up to 75% than H.264. Besides that, this device can provides MPTS/SPTS/ASI independent multiplexing output and IP output channel switch.
With PSI/SI technology to modify the audio and video PID information of the output program, OTV-EP25 Multi-Channel HD Encoder also supports to insert a NIT information table into the WEB to achieve better compatibility with the backend devices. OTV-EP25 supports to edit program number and name of the output video stream, and the logical channel number setting can also be added to the encoder.
Overall Dibview's encoder/modulators with OSD/Logo/QR code Insertion function, which perfectly suit any professional SD/HD Video company, including TV Channels, Live broadcasters, Government applications, Hotel, Campus, Entertainment facilities, education broadcasting systems at schools and government buildings and many others. Many outstanding features are integrated into OTV-EP25, In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as cable TV digital head-end (CATV), digital TV broadcasting (DTV), and OTT IPTV streaming projects.
