The video surveillance industry is surging rapidly not only in terms of technological advances, but also in terms of adoption in new applications sectors. The first new products of the video decoder family are targeted to the PCIe-based DVR and video security systems. The new and highly integrated video decoders help to solve the signal integrity of the incoming images. By using a proprietary sync-tip design, and integrating industry leading PCI Express technology, Pericom's new 4 and 8-channel video/audio decoder IC's recovers and boosts a weak, unstable composite signal over a long single cable connection.
Features and Benefits
Pericom's industry leading PCIe technology with advanced 4 and 8-channel video decoder functionality to handle the latest system monitoring requirements.
- Built-in Automatic Gain Control (AGC) and Digital Signal Processor boosts the 60mVp-p weak composite video signal.
- Proprietary sync-tip detection can decode a signal across up to 500-700 meters of coaxial cable for standard NTSC/PAL video signals.
- 5-line adaptive comb filters for optimal Luma-Chroma separation reduce the color bleeding effect.
Solution Diagram
Pericom single chip video decoders can support both 4 and 8-channel live composite inputs with 10-bit audio ADC, and can also support non-real time 8 or 16-channel inputs. The PC7C9X9208 together with PCIe GEN2 packet switching, can support up to a maximum of 64-channels. Standard I2C audio output can activate the audio sensible recording systems to efficiently control the security storage capacity management.
