For immediate release

See Leader on stand 11.A38 at IBC2014, RAI Amsterdam, September 12-16, 2014

Fullerton, California, USA, August 1, 2014: Leader Instruments will introduce the new LT4600 multi format video generator at the September 12-16 International Broadcasting Convention, IBC, in Amsterdam.

Developed from the established LT4400 HD-SDI and SD-SDI generator, the LT4600 adds compatibility with 3G-SDI and dual link systems.  Its two SDI outputs can be used independently from each other. A lip sync testing function, optional in the earlier model, is included as standard in the LT4600. This feature allows measurement of timing offsets caused by latency differences between video and audio processors. The compact 1U half-rack-width dimensions of the  dimensions of the LT4400 are retained.

The LT4600 can generate ID characters for superimposition at any operator-assigned position on the output display. A user-defined logo of up to 320 pixels width by 240 lines depth (QVGA) size can also be positioned anywhere on the screen. This logo is converted from a bitmap to four-levels of monochrome.

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. A motion picture mode is provided to scroll the pattern.

Audio facilities include the ability to generate 32 channels of embedded audio. These consist of link A and link B, each comprising 4 channels by 4 groups for 3G-SDI. 16 channels of embedded audio signals (4 channels by 4 groups) can be superimposed.  Frequency and level can be set for each channel.

The LT4600 can be locked to NTSC/PAL black burst or HDTV tri-level sync signal. A Stay-In function can be used in case of genlock input errors.

Three independent analog black signal outputs are provided.  Black burst can be selected with the same format as the SDI output. HDTV tri-level sync with the same format of clock frequency can be selected for variable timing. A 48 kilohertz wordclock output plus a 48 kilohertz AES/EBU output are provided to synchronize the audio signal.

The  LT4600 supports SNMP protocol, allowing easy integration into a networked system. User data can be saved or updated via a USB interface.

Exhibiting on stand 11.A38, Leader will be represented at IBC2014 by Masahiro (Hiro) Sawa (President, Leader America), Richard Heath, Koichi Fukugawa and Christian Young.
