STi7710 Single-chip, low-cost high definition set-top box decoder DATA BRIEF 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. Figure 1.
