Arcsoft Totalmedia 3 TV/Video/Picture application software
Dimension of 310u is about 6 inches by 4 inches with an LED in front
and signal connectors in back. From the drivers installed the main chips
used in the device are eMPIA usb interface and Xceive silicon tuners.
No problem installing drivers or Arcsoft app on AMD64 XP SP2 system.
Arcsoft Totalmedia detects one internal tuner and the external 310u.
Philips silver sensor antenna is connected up with Kworld supplied RG59
cable and after signal detection of channels. lists five. This is less than
half available channels, so thicker RG6 is used for antenna connection
and now eleven channel are detected.
With antenna positioned in one direction, approx four of channels come
in clearly while the others require careful adjustments to acquire both
audio and video.
One NBC WX station screen capture is attached.
Overall quick assessment is combination of tuner and app software
for under $70 is good, but hope that an inexpensive antenna less
than $50 is available to complete a satisfactory budget system.
