 ENC-204IP (4 in 1 IP output)
|
|
ENC-204IP 4 in 1 IP encoder is a user-friendly,powerful MPEG-2 encoder. It supports analog composite video and mono/analog stereo signal, and combined with one ASI input which supports MPEG-2 transport stream re-multiplexing. The format of the output of compressed data is ASI/SPI, besides it support IP output, which can be connected with the Internet. It can maximally encode 4 A/V inputs and multiplex the correspondent 4 SPTS as 1 MPTS output. By compressing input as MPEG-2 MP@ML format, coder real-time encodes and multiplexes audio signal according to MPEG-2 format, and then, generating DVB transport stream. It completely complies MPEG-2 standard, and it has high compatibility. Its dimention is 1U standard case. By watching the LCD display on the front panel, user can finish the setting of auto-running of this machine.
