Also, the Hauppauge pvrusb2 also uses an FX2, with an almost identical firmware command set, except special commands to handle the cx23416 encoder are not present in the Medion and DViCO devices. Both the Medion box and the pvrusb2 return 0x08 as a success message in response to firmware commands, in particular, 0x08 - i2c write. However, the Bluebird box always returns 0x01. Once again, the driver doesnt care about the return codes, so we have no problem here. >> - Support for FusionHDTV ATSC using alt setting 7 on DVB-T firmware > > Do you think you can try that easily?

AFAIK, there are four different bluebird boxes, each using different tuner / demod combinations. LG-H064F, containing lgdt3303+tua6034+tda9887, for use with ATSC / NTSC . Some others: LG-Z201 + Zarlink MT352 (DVB-T) Thomson7579 + Zarlink MT352 (DVB-T) Dnos104Z + Zarlink MT352 (dual DVB-T) I haven't tried it yet, but it should be as simple as just changing the Alt setting to 7, while using the DVB-T firmware on the ATSC box. I will give that a try, and I have no doubt that it will work. What I would like to do is support both firmwares for the ATSC box. I think it would be nice, if the driver would allow for using the DVB-T firmware if the ATSC firmware isnt present (or vice versa) However, this has some implications.... I'll try the DVB-T firmware first, It would be nice, if anybody has the DVB-T version of this box, to let me know and test out some patches. ...or maybe it would be better to ONLY support the DVB-T firmware, since it should work on all the bluebird boxes, using different alt settings. I'll have to test that first... > Otherwise: (Don't know what is correct): > > Signed-off-by: Patrick Boettcher <pb@xxxxxxxxxxx> > or > Acked-by: Patrick Boettcher <pb@xxxxxxxxxxx> > > regards, > Patrick. I'm not sure either which is better.... I guess I'll decide when I commit it to cvs, if you dont pick one first. ;-) Cheers, Mike
