STi7710
Single-chip, low-cost high definition set-top box decoder
Rev. 1
DESCRIPTION
The STi7710 is STMicroelectronics' first single
chip set-top box decoder for high definition
applications, and meets the requirements of all
services in the United States, Japan, Australia, as
well as the emerging European market.
By combining all the features of an HD decoder
onto a single device, ST has ensured the lowest
possible costs for set-top box manufacturers.
As well as including ST's enhanced security
features, the STi7710 supports the High Definition
Multimedia Interface (HDMI) and High-band width
Digital Content Protection (HDCP) standards.
These features ensure the STi7710 effectively
meets the security requirements of content
providers and operators.
The STi7710 embeds a wide range of peripherals,
including a high-speed USB host interface, and
provides connectivity options, including the ability
to provide DVR capability.
