Fushicai USBTV007

The Fushicai USBTV007 is the recommended analogue capture device for the Portsdown Transmitter. Other devices may work, but are not so well supported. You can identify your video capture device by entering "v4l2-ctl -d /dev/video0 --info".

Inputs

The USBTV007 has 2 video inputs, composite and S-Video. The composite video input is selected by setting the input number in the Portsdown Menu (System Setup, Set-up EasyCap) to 0, and the S-Video input by selecting the input number to 1. In other Linux installations, the commands "v4l2-ctl -d /dev/video0 --set-input=1" and "v4l2-ctl -d /dev/video0 --set-input=0" may be used. The audio inputs are common to both video inputs.

Standards

The USBTV007 is capable of capturing PAL or NTSC. PAL is selected by setting the standard number to 6 in the Portsdown Menu, and NTSC by setting the standard number to 0. In other Linux installations the commands "v4l2-ctl -d /dev/video0 --set-standard=6" and "v4l2-ctl -d /dev/video0 --set-standard=0" may be used.

Capture Resolutions

The capture resolution is 720x576 for PAL and 720x480 for NTSC. 1440 bytes are captured for each line in YUYV format.
