A hybrid ATSC USB 2.0 device by Evga.
Overview/Features
This device supports ATSC (i.e. OTA Digital TV) and analog NTSC. The package includes a small telescoping monopole antenna and a short USB extension cable, a remote control, and a connector to svideo or composite video inputs.
Components used:
- (tuner & analog demodulator)
- (digital demodulator)
- (video decoder)
- Empiatech em2883 (USB bridge and analog audio)
Identification
The device identifies itself as a "eMPIA Technology, Inc" and the subsystem information provided by lsusb -v is ebla:2883.
Making it Work
This tuner is very difficult to get to find channels when scanning OTA ATSC. There is a thread about getting it to work which assuming you are familiar with the concept of frequency lists, as defined in /usr/share/dvb/atsc is very helpful at http://www.digitalhome.ca/forum/showthread.php?t=134023
Making it work is actually pretty simple. You will need to modify the standard ATSC frequency list which has the wrong center frequencies for this tuner. Using vim or your favorite text editor modify the center frequencies in the intial-tuning-data contained in the text file /usr/share/dvb/us-ATSC-center-frequencies-8VSB and save it in /usr/share/dvb/atsc as my-ATSC. You need to subtract roughly 400 Khz from each center frequency. I subtracted 403615 Hz from each frequency so it falls in the exact center of what the InDtube Tuner can lock. From then on be sure to specify this file when scanning for channels with scan:
Scanning for channels.
scan -a 1 /usr/share/dvb/atsc/my-ATSC -o zap mychannels.conf
