        The Evolution1 series is based on the Philips STB810 reference platform, which is built around the Nexperia PNX855x Home Entertainment Engine, a multi-core system-on-chip (SoC) processor that includes a MIPS32 CPU core along with dual TriMedia media processing cores.

        Basic hardware specs of the STB810 reference platform -- which are shared by all three Telegent Evolution1 STB platforms -- include:
        • CPU speed -- 250/280/310 MHz
        • Media core CPU -- 240/270/300 MHz
        • DDR RAM -- 32 to 128 MB
        • Flash -- 16 to 64 MB
        • Video out -- PAL or NTSC, S-Video, Composite Video, HDMI, S/PDIF
        • Audio out -- Stereo RCA jacks
        • I/O ports:
          • 10/100 Ethernet, RJ45
          • 4 USB 2.0
          • Asynchronous serial port
        • Expansion -- MiniPCI slot option
        The platform supports variable bit rates from 300Kbps to 4Mbps and resolutions up to full D1 at 30fps and 720p. Supported "trick modes" include:
        • Play / Pause / Stop / Step / Goto / Fast Forward / Rewind
        • Change video playback speed
        • Record and timeshift of DVB
        Telegent says it has several extensions planned, including:
        • WiFi and Bluetooth wireless using the MiniPCI slot
        • Hard disk up to 250GB via USB
        • DVD Player/Recorder via USB
        • Photo Printer via USB
