Texas Instruments (TI) today announced the availability of three new multi-channel video decoders which the company promises will deliver superior picture quality. The new decoders namely TVP5158, TVP5157 and TVP5156 feature advanced 2D adaptive comb filter core and image enhancement techniques such as auto contrast and video noise filtering, claims the company.

The new TVP515x series solutions are designed for applications such as video surveillance as well as video conferencing systems. The new solutions can also be used digital video recorders (DVR), digital video servers (DVS), hybrid DVRs, cameras for video conferencing and digital signage products.

TI also claims that flexible video outputs on the TVP5158 and seamless interface to TI digital media processors reduce system cost by $ 10 by eliminating the need for an external FPGA.

Key features and Benefits of the new decoders:

• Four high-quality NTSC/PAL video decoders on each TVP515x chip can concurrently decode four video channels and then stream a single output to the DSP, enabling customers to benefit from a lower cost per channel.

• High-quality five-line adaptive comb filter algorithms for all NTSC/PAL standards.

• Multi-chip operation with two TVP5158 devices allow for simultaneous eight channel half D1 or eight channel CIF output.

• Auto contrast improves image quality under poor lighting conditions and off-loads processing from the associated DSP, giving customers more headroom to implement other algorithms.

• Video noise reduction with 2D spatial filtering improves image quality and compression ratio under poor lighting conditions for better storage compression.
