Overview

The OV788 is a highly integrated multimedia camera processor aiming for consumer, security & surveillance, automotive (after-market) and video conferencing applications. It provides low system integration cost without requiring external memory while maintaining the flexibility of expanding an external SDRAM as needed. The OV788 runs efficiently and consumes low power.

The OV788 supports up to three camera interfaces, including one dedicated single-lane MIPI receiver, one dedicated DVP input port, and one shared DVP input ports.

The OV788 has an embedded advanced image signal processor (ISP) to support 720p HD raw image sensors at 30 frames per second (fps). Along with an embedded compression engine, the OV788 supports still picture capture up to 16MP at 5 fps. It also supports still picture playback.

The OV788 implements an advanced video engine to achieve high-performance video recording or decoding up to the 720p resolution at 30 fps without requiring any external memory. The engine is capable of recording dual video streams up to VGA resolution at 30 fps, or decoding dual video streams up to VGA at 30 fps and quad video streams up to QVGA at 60 fps. Along with an embedded audio engine and depending on audio formats, the OV788 records and decodes mono/stereo audio with video clips.

The OV788 supports various types of LCD displays up to 720p HD with color depth up to 24-bits (RGB888). The LCD interface shares one DVP output port that can connect to external devices such as an HDMI transmitter. The OV788 also supports analog TV output.

The OV788 combines various parallel and serial peripheral interfaces including a storage card interface, serial interface, serial audio interface, SCCB interface, UART interface, USB device interfaces with embedded PHY.

OmniVision has teamed up with Texas Instruments and created a reference design for battery-operated smart home security cameras. This new reference design combines OmniVision's power-efficient Video Processor and HD image sensor with Texas Instruments' Wi-Fi® technology that can help innovative startups and small- to medium-size smart home camera manufacturers compete in the rapidly growing do-it-yourself (DIY) smart home security system market.
