Names and Functions of Parts
Overview
The MSB-2000 Multi-Format Stream Bridge provides
SDI, SDTI-CP, DVB-ASI and 100Base-TX with
MSBA-20IP network adapter board, and is a stream
converter which performs MPEG2 encoding/decoding
(sdi_to_asi, sdti-cp _to_asi, asi_to_sdi, asi_to_sdti-cp,
tx-rx (sdi_to_asi/asi_to_sdi), tx-rx (cm)).
Features
Audio and video compression
The MSB-2000 has several encoding modes (IMX,
Normal, Normal BL, Low delay and so on) that
provide the best balance between the encoded picture
quality, the codec latency and the bit rate depending on
the particular manner of use.
The MSB-2000 has audio encoding and decoding to
MPEG1 Layer II Audio (four channels) and SMPTE
302M LPCM Audio (eight channels).
For more details, see the List of Menus (page 36).
Parameter referring re-encoding
1)
Parameter referring re-encoding keeps up the superb
MPEG picture quality at mutual conversions between
Long GOP and Short GOP (All I CBG (IMX)). It can
minimize generation loss when reiterating GOP
conversions by using the history data.
Simultaneous encoding/decoding function
In case of tx-rx (sdi_to_asi/asi_to_sdi) or tx-rx (cm)
mode, encoding and decoding can be carried out
simultaneously.
Operation control
The operator can control the MSB-2000 from the front
panel or through an HTTP, Telnet, or RS-232C
interface. The system incorporates a GUI which can be
accessed with an Internet browser without requiring
special-purpose control software, for unit setup and
VTR/disk recorder remote control via an RS422A
interface.
Network monitoring function
The system supports SNMP (Simple Network
Management Protocol) used in the telecommunications
industry for network monitoring/control.
VBI Transmission
The MSB-2000 (TX side) transmits VITC, closed
caption (available only in a 525 video system), UMID
1)
and uncompressed data in the VBI information of SDI
input video as private data.
Resume function
The resume function preserves mode settings after a
power off, allowing the system to be started up after
power on with the saved settings.
Fitted with alarm contact output
If an error occurs in the MSB-2000, in addition to the
alarm indicator on the unit, both SNMP and relay
contact outputs are available.
Self-diagnosis function
The self-diagnosis function operates when the unit is
powered on, and the self-diagnosis information (log
message) is output on the Telnet and RS-232C
interfaces and SNMP.
Optional Accessories
MSBA-20IP network adapter board
This network adapter board, installed in the unit,
provides UDP/IP based bidirectional realtime material
transfer by RTP (realtime transport protocol).
Maintenance manual
This manual contains the information needed for
servicing at the main component level (error messages,
service parts list, overall block diagram and so on.)
Power cord
This connects the AC power inlet on the rear panel of
the unit to a power source.
RMM-30 Rack Mount Rail
Consists of slide rails to mount this unit in a 19-inch
standard rack.
