Dual Channel VANC Modem


VANC multiplexing for two lines of input

VANC modem applications:

  • Multiplexes data such as camera platform and lens sensor data in virtual systems into video signals, or demultiplexes data from the video signals

  • Program-related data and other information can be multiplexed in video signals for data transmission between broadcasting stations

  • File transfer capability using a specialized application


Ancillary transmission

Using the ancillary space of SDI data (as defined in BTA S-005B and STD-B6), multiplexes information from the serial port as data packets (as defined in ARIB TR-B22 or TR-B23). Two HD/SD-SDI lines are supported.

Ancillary reception

Data acquired from ancillary data packets supplied via SDI input are used in output from the serial port. Ancillary data packets used in transmission are replaced with dummy packets before SDI output. Two HD/SD-SDI lines are supported.

Transmit/receive switching

On the unit, operation can be switched between transmitting and receiving.

Selection of multiplexing packets

DID/S-DID values of ancillary data packets to multiplex can be freely set, as can the packet multiplexing line and packet position.

Up to two lines for one serial input/output port

Simultaneously transmits up to two lines of serial data.

Multi-block function

Supports a high baud rate by creating packets.

Packet monitoring

Packets passing through can be checked in test mode, enabling monitoring of packet positions available for recorders or the transmission path.

SD/HD support

Supports both HD-SDI (1080/60i, 59.94i, 50i, 24PsF, 23.98PsF, 24p, 23.98p) and SD-SDI (480/59.94i).

Status indicators

Front LEDs show the status of SDI input and serial communication.

Display for communication status

Indicates the status of packets and lines used in transmission or reception. Settings can be viewed or adjusted in menu mode.

SDI pass-through

Pass-through of one line of SDI input is maintained during power outages.


Transmission in conjunction with EVM-2530T/2530R or EVM-2600 is supported.

Emergency data transfer

In emergencies that disable fax machines or other communication, documents or files can still be sent via video networks. Useful as an alternative means of file transfer.
