How to make my own hardware support TVH?

Wilbert Lin

Hello everyone,

I build my own dvb device using ite bridge and montage DVBS2 demod/tuner , sony dvbt2 demod/tuner.

How can i make my own device support tvh?

Now i already build my own driver and i can run it under linux to lock signal and receive TS.

it seems that i have to make it support dvbfe (the driver is from ite , montage and sony but ite is an usb to ts bridge)

can i modify tvh to make it support my own driver?

How device is connected to Linux?

USB/PCI/Network other way?

Usually are used DVBAPI protocol with is connected to kernel etc.

then DVB application communicate with it.

Most of device driver/modules are Open Source but firmware for them are not.

the device hw diagram is like this:

Montage RS6060 <-------------->
Sony DVBT2 CXD2881_1 <-------->---> it9305 (TS to USB) <-----> USB <----> SoC

Sony DVBT2 CXD2881_2 <-------->

In Linux, there are devices under /dev/ called it930x0/it930x1/it930x2. I inserted the .ko module using insmod, and the ko was modified and built from the ITE driver porting, Montage, and Sony driver porting.

But it seems totally incompatible with dvbapi.

Is it necessary to modify it to be compatible with dvbapi?

I'm not so sure how TVH connects with HW.

It need to appear in

/dev/dvb
