Philips MPEG2 codec accelerates DVD recorder development

Royal Philips Electronics has launched the pnx7100, an integrated audio, video, and graphics MPEG2 codec that targets laser disk- or hard disk-based digital recording systems. It is claimed by the company to reduce DVD recorder development times by as much as 35 percent.

"The pnx7100 chip offers a total solution to Asian manufacturers of DVD recorders," said Jeroen Keunen, head of consumer and multimedia with Philips Semiconductors in Asia Pacific. "Until now, DVD recorder manufacturers have needed to use a separate MPEG2 encoder, separate MPEG2 decoder, sometimes even a separate chip to do transcoding from DV-to-MPEG2 format, and separate memory for each of these chips."

He added that "by combining all of these features on one chip greatly reduces the bill of materials and speeds up the development cycle."

The chip is supported by the DVD+RW software stack and provides compatibility with existing DVD-Video and DVD-ROM equipment to allow media interchange between consumer electronic equipment and PC platforms.

The pnx7100 performs MPEG2 encoding, decoding and transcoding capabilities, and can support multiple digital video-recording standards including DVD+RW or Hard-Disk Personal Video Recorder.

Based on the company's Nexperia platform, the IC also includes a high performance MIPS CPU core and a unified memory architecture that allows the MPEG subsystems, graphics and CPU to share the external SDRAM. External memory mapped peripherals can be connected to the PCI-XIO bus interface.

The encoder function includes a video-input processor, a video encoder, an audio encoder, an IEEE 1394 interface and software multiplexer. A watermarking detector is included for digital rights management.

The pnx7100 can be cascaded to form a DV-to-MPEG, or an MPEG-to-MPEG transcoder.
