The GC6500 is a highly integrated, low-power H.264 Codec that supports video encoding up to High Definition (1920 x 1080p60) resolution. The GC6500 features advanced video encoding and processing with HD H.264 encoder and processors such as High Dynamic Range (HDR) Image Signal Processor (ISP), Geometric processor (eWARP®), and Video preprocessors. The device also incorporates an Xtensa LX4 processor and a RISC processor along with a number of peripheral and serial device interfaces for I/O and system control integration.

Combining high-quality video encoding with advanced video processing, the GC6500 is an ideal, cost-effective solution for secured video monitoring and internet video conferencing applications.

Leveraging the chip’s high performance and integration capabilities, the GC6500 delivers superior video and audio quality while significantly reducing cost and power consumption of the system. The advanced video processing blocks coupled with the flexible hardware architecture provide best in class video processing capabilities such as ultra wide angle and fish-eye correction, wide dynamic range video processing, and multi-stream encoding support. The audio processing algorithms such as beam forming, noise suppression, and echo cancellation implemented in the firmware improve signal noise ratio removing the need for external audio processing. The integrated Analog to Digital Converter (ADC) and power circuitry eliminate the need for external components reducing overall system cost.
