Zoran Corporation announced that it is demonstrating at the HDTV conference a complete hardware and software solution for building an integrated Digital Television (DTV) targeted at the United States market.
The reference design, based on Zoran's SupraHD 660 processor, is a full featured system that
allows tuning, decoding and display of analog (NTSC) and digital (ATSC) terrestrial
broadcast. The SupraHD processor includes an MPEG-2 decoder, NTSC video decoder, HDMI
receiver, IEEE-1394 interface, audio DAC, and an advanced video processing engine to control
and directly drive LCD and other high definition television displays. The reference design
also includes Zoran's Cascade 2 front-end demodulator that supports VSB and QAM modulation
schemes.
The new ATSC/NTSC compliant reference design reduces the overall system cost for
manufacturers of digital televisions due to the high level of integration within the SupraHD
660 IC, the cost-effective Cascade 2 demodulator, and the partnerships Zoran has with other
component suppliers represented on the board.
Performance and picture quality is achieved through Zoran's video processing, which provides
edge enhancement, color correction, adaptive contrast enhancement, and motion adaptive
deinterlacing.
The reference hardware module accepts composite (CVBS), S-video (Y/C), and component (YPbPr)
inputs processed by the on-chip 3D comb filter color space converter. The output interfaces
can directly drive an LCD/PDP panel or a CRT TV. Other outputs include L/R audio for
internal speakers and SPDIF for multi-channel output to an external audio receiver. The
complete hardware design also supports basic application functionalities required for a DTV,
such as ATSC/NTSC software stack, Electronic Program Guide (EPG), closed-caption decoding,
parental control, basic audio control, and basic video control. For ease of connectivity to
external devices, the IEEE-1394 software stack is also bundled with the software package.
Complete reference designs (ZR8390660-ATSC-LCDX) are available now for qualified Zoran
customers. |
