SupraTV 260

Interactive Cable Set-Top Box Processor

Overview

Overview

SupraTV® 260 processor also supports single or dual tuner Digital Video Recording (DVR) through a USB 2.0 high speed interface.

Combining the key functions required to support digital cable Set-Top Boxes, the SupraTV® processor enables products with enhanced flexibility and performance to be developed at the lowest possible system cost.

A high performance MIPS® processor provides access to Zoran and industry standard middleware and leverages previous SupraTV® software. With a comprehensive set of software drivers, proven tool kit and reference platforms, the SupraTV® 260 processor keeps product development times to a minimum.

SupraTV® 260 Development Platform

A comprehensive development platform is available for the SupraTV® 260 processor, including tuner boards for digital cable Set-Top Boxes. An Integrated Development Environment includes a proven windows based GNU tool kit, Zoran’s SiliconSoftware® registration drivers, and applications that add functions such as flash memory burning, high performance code download, software protection, a sophisticated GUI development tool, (Embedded Wizard), and an automatic code generator.

The SupraTV® 260 platform significantly reduces the time taken to develop high performance, cost optimized cable Set-Top Box products. The SupraTV® 260 processor based evaluation board supports all needed peripherals including ethernet and USB. The platform is available with a cable tuner. Single and dual tuner Digital Video Recording capabilities can be achieved by adding a USB based hard drive, Zoran’s DVR software, additional memory, and a second front end (for dual tuner DVR).

Zoran SiliconSoftware® API Package

Zoran provides software support for the SupraTV® 260 processors and a documented Application Programming Interface. Based on the company’s extensive Set-Top Box, DVD and Digital TV experience, the API provides a stable base on which users can build their own applications.

The software stack, including the operating system (Nucleus+), is available on a royalty-free basis. Zoran’s SiliconSoftware API is supported from previous SupraTV® ICs.

Software portability from one generation to the next minimizes project design time and effort while enabling the software to be reused. Other components of the standard software package include a sample Electronic Programming Guide (EPG), close captioning, DVB and US subtitle and OSD Teletext decoding.
