HD video-over-coax interface for surveillance, industrial image applications

Gennum Corporation has developed a new audio video interface for professional and industrial applications, such as advanced video security and surveillance systems. Aviia (Advanced Video Interface for Industrial Applications) is a robust interface for high definition (HD) video over coaxial cable lengths up to 100 meters.
This allows users to upgrade their existing analog over coaxial systems, the dominant technology implemented in surveillance systems today, to full bandwidth HD video, up to 1080 lines progressive. The new interface expands the technology into new markets including video surveillance, machine vision, medical, digital signage, passenger infotainment, industrial imaging and video conferencing.

Highlights and features of this product are,

1. The Aviia interface and accompanying suite of products can be easily integrated into the architecture of digital video equipment, such as cameras, monitors and digital video recorders (DVRs).
2. Featuring transmit and receive functions to enable bi-directional transmission, the Aviia solutions create a new I/O capable of transmitting across coaxial cables.
3. The use of this interface ensures that the HD stream from source (camera) to destination (DVR, monitor, etc.) is transmitted at full bandwidth with no video compression needed.
4. Suite of A/V products brings an alternative to Ethernet, Cat-5 implementations. Gennum uses its serializer/deserializer technology to achieve this end-to-end upgrade path for HD video transmission over 100 meters plus of coaxial cable.
5. Gennum's new Aviia suite of products deliver a high-bandwidth, all-digital, long-reach A/V interface for professional and industrial applications.
6. Integrating into existing digital architectures, the products provide high-definition video; digital audio; bi-directional control such as pan-tilt-zoom and camera configuration, over a single-wire.
7. The Aviia suite of solutions provides for power over the coaxial cable itself, operating at 3 to 25 volts DC, up to 25 watts.
8. Gennum's Aviia suite includes the GV7500/01 Aviia SD transmitter/receiver; the GV7600/05 Aviia transmitter/receiver (supports both SD & HD video) and the GV7601 Aviia receiver (SD and HD support with integrated cable equalizer technology).
9. With support for 720p, 1080i and 1080p video formats, as well as 525i and 625i (D1) video, Gennum's new Aviia solutions enable HD video to be transmitted without the use of in-camera compression.
10. Providing a single 75-ohm coaxial bi-directional multi-media interface, the new suite of products can provide link bandwidth up to 3 Gb/s downstream and can support up to 8 channels of linear PCM audio at 48 kHz sampling.
11. Aviia solutions provide support for 6 Mb/s auxiliary data channel, for applications such as up-the cable control, "intercom" audio back channel, and remote status and monitoring.

Availability:

1. A complete reference design for the HD over coaxial cable solution will be available in April.
2. The GV7600/05 HD devices are available now in high volume
3. The GV7601 receiver will be available in September

Price: $7.56 each in quantities of 10,000/month for GV7600/05 HD devices
