Product description The LT4600 Multi Format Video Generator with Lip Sync from Leader is a 1RU half-rack sized multiformat video generator applicable to 3G-SDI, HD-SDI, and SD-SDI systems. The LT4600 features color bar, SDI check field test pattern, ID characters, logo mark in QVGA size, safety area marker, embedded audio, genlock model for external reference synchronization, and three independent analog black signal systems. The Lip Sync function is a key feature of this video generator. - Accepts 3G-SDI, Dual Link, HD-SDI, and SD-SDI systems.
- SDI outputs can be used independently from each other.
- Lip Sync Function included as standard.
- The ID characters can be superimposed at any arbitrary position on the screen.
- A logo mark (up to 320 pixels by 240 lines) in QVGA size can be superimposed at any arbitrary position on the screen. Logo is converted from bitmap to four-grade monochrome data.
- 90% and 80% safety area markers can be superimposed on the screen.
- A 4:3 aspect ratio marker can also be superimposed in 3G-SDI or HD-SDI formats.
- Simple motion picture mode is provided to scroll the pattern.
- The 32 channels of embedded audio signals (link A and link B - each 4 channels by 4 groups) for 3G-SDI (level B), and the 16 channels of embedded audio signals (4 channels by 4 groups) can be superimposed. The frequency and level can be respectively set for each channel.
- The instrument can be locked to NTSC/PAL black burst or HDTV tri-level sync signal.
- In case of genlock input errors, a Stay-In function is available.
- Three independent analog black signal outputs are provided. The black burst signal with the same format as the SDI output, or HDTV tri-level sync signal with the same format of clock frequency can be selected for variable timing.
- A 48 kHz word clock output and a 48 kHz AES/EBU output are provided to synchronize the audio signal.
- Supports SNMP protocol to easily construct a network system.
- USB slot on the front panel to save and update user data settings.
