The Codec2x29 represents a new generation of video compression and multiplexing
capability. Targeted for ISR video data link applications, the Codec2x29
includes the following features:
Simultaneously supports multiple channels of asynchronous and synchronous data, toll quality audio, video, and GPS meta-data.
Reconstructs all needed clocks automatically at the receive end of the link.
Airborne-quality unit occupies just 29 cubic inches and can be configured as either an encoder/multiplexer or a decoder/demultiplexer.
Error-resilient, low-latency, high-quality motion JPEG video compression with restart markers. Latency of 3 frames or less with usable video at BER worse than 1e-4.
Works with all standard definition analog video formats: NTSC / PAL / monochrome / color / composite / Y-C.
Multiplexed bit stream rate from 20 kbps to 10 Mbps with clock generated internally or provided by host system.
Cascade units to support multiple simultaneous video streams on one data link. Share bandwidth in any proportion between the video sources.
Operating temperature from -20 to +70°C.
<350-mA curent draw with MIL-STD-704 28 BDC input power.
Codec2x29
The Codec2X29 is built around a flexible and expandable multiplexing protocol designed specifically for ISR applications. This on-demand protocol introduces very little overhead and allows the combination of a wide variety of different data types, including asynchronous data whose bandwidth demands may vary widely over time. The protocol provides bandwidth to data services first and then uses all remaining bandwidth for video, adjusting frame rate as needed to maintain image quality in the available bandwidth. Support for per-frame meta data allows tagging individual frames with GPS, time of day, and other user-defined information.
