INS-VPS
SDI 신호에 basic VPS를 삽입하는 장비
RS-232 컨트롤
입력 : 1 x SDI
출력 : 2 x SDI VPS Signalling Encoder
Features
Insertion of basic VPS information
Front Panel or Remote Control
1U rack mounting unit
Serial Digital Video
The Microvideo VPS Signalling Encoder provides a means of inserting the basic control data that
is provided within the VPS stanadard as described in document IRT Paper no. 8R6, Jan. 1993.
For Example
Youth protection
TV Station Identification
Sound Coding Data
Note : The unit does not implement the VTR control information (program delivery data) words.
The unit can be controlled either from the front panel or remotely using GPI inputs.
1 of 4 functions can be controlled remotely.
GPI 1 Youth Protection
GPI 2 Audio Mono
GPI 3 Audio Stereo
GPI 4 2 Channel Audio
An analogue input option allows insertion of analogue teletext and analogue VPS data.
An Monitoring Option provides a Analogue PAL output
If required Insertion Test Signals can also be generated internally and inserted. These may be
either ther UK patterns or the CCIR patterns (CCIR17,18,330,331)
Product Codes
INS-VPS VPS Data Inserter for SDV(270Mb/s), in 1U frame with front panel controls
option
-AN Analogue Data (Teletext or VPS) input
-MON Monitoring PAL output
-ITS Insertion Test Signals (UK or CCIR)
Product Specification
INPUTS: SDV(270Mb/s) on BNC to EBU tech 3267, SMPTE 259M
OUTPUTS: 2 x SDV(270Mb/s) on BNC to EBU tech 3267, SMPTE 259M.
On power failure the SDV input is routed to the Main Program (PGM)
output by an RF relay.
Note : The digital video path through the unit is 10 bit and transparent to
Embedded Audio. The unit will pass the EDH checksum packet but
does not recalculate a new value for it.
With the Analogue Input option the follow are also provided
Analogue 1 For Analogue Teletext VBI data
Analogue 2 For Analogue VPS data input.
