Description

The BCM7320 is a highly integrated single-chip satellite set-top box decoder that incorporates dual QPSK receivers, an MPEG-2 A/V decoder, MIPS64™ CPU and peripherals. BCM7320 is the first complete DBS set-top box solution to simultaneously decode multiple transport streams, that BCM7320 can contain different program streams, delivered either via the external dual BCM3440 CMOS tuners or via the IDE host I/F from an external hard disk drive, or any combination thereof, and display the decoded audio and video on two TV monitors connected to the same set-top box. The Broadcom 2-D graphics engines incorporated into the chip offers true studio-quality text and graphics with extremely efficient use of memory and bandwidth. PVR capability in the chip offers personal viewing and scheduling, video-on-demand (VOD), and VCR "trick mode" effects on both TVs simultaneously.
