General description
The PNX7100 is a single chip AVG (Audio, Video and Graphics) MPEG-2 CODEC suitable for both laser and hard disk based digital recording systems. It provides manufacturers of DVD recorders with a total back end solution to facilitate quick product development within an emerging consumer market segment.
Combining high quality MPEG-2 encoder, decoder and transcoder functions with the memory required, the PNX7100 is a one chip solution which greatly reduces the bill of materials. To provide maximum compatibility and interoperability, the PNX7100 supports the industry standard DVD+RW software. This, combined with the highly integrated nature of the chip, allows for rapid development and short time-to-market.
By providing maximum compatibility with existing DVD-Video and DVD-ROM equipment, the PNX7100 allows for media interchange between consumer electronic equipment and PC platforms. It also enables both home-recorded and pre-recorded disks to be played on the same equipment.
The PNX7100's decoder function includes a sector processor, a CSS decryption block, an MPEG PS and TS demultiplexer, an MPEG video decoder, a DV decoder, a multi-format audio decoder and a DVD sub-picture decoder. The encoder function includes a video encoder, audio encoder, IEEE 1394 interface and software multiplexer. Functionality is also included for digital rights management. The PNX7100 can perform DV-to-MPEG or MPEG-to-MPEG transcoding. MPEG data is passed from decoder to encoder to aid in achieving a high quality transcoder. To further reduce system costs, the digital video encoders (DENCs) are also integrated into the chip.
