Sony has announced that owners of a compatible Bravia TV can purchase the BRX-A320 DVR, which has a 320GB HDD for recording up to 27 hours of HD video and 55 hours of SD, or up to 249 hours of content in LP mode. There is just one HDMI port in the device, though users can still record SD content thanks to one of four selectable recording modes. In the name of space efficiency, the DVR can mount on the back of the compatible Sony TVs thanks to a mount purchased separately.

The A320 has a built-in digital tuner, compatible with digital terrestrial and BS 110 broadcasts. The recorder is compatible with X7000, X5050, X5000, W5000, V5000, V3000, J5000, J3000, XR1, X1, W1, F1, V1, J1, V5 and J5-series TVs; a remote control is included.

The DVR will be priced at the equivalent of about $550 when it goes on sale in Japan on February 20th. [via ImpressWatch]
