1.  Release note

    This software package release is version 9.12.18.1.

    Driver component version information:

	1. Firmware :   v1_0_12_0

	2. API      :   2.0.20091116.0



    The driver is for ITEtech 9135 based USB TV module and operates

    on Linux platform.



    This release supports x86 32bit and 64bit CPU families in Linux.



2.  Revision history

    Features added and bugs fixed in v9.12.18.1,

    (1) First release.







3.  File and folder descriptions



    \32bit\IT9135_SRC.tgz                   ITE9135 USB device driver source code package for 32 bit CPU

    \64bit\IT9135_SRC.tgz                   ITE9135 USB device driver source code package for 64 bit CPU



4.  Feature descriptions

    IT9135 Linux driver is implemented with the video for Linux (V4L) interface

    that greatly simplifies software integration. It performed the tasks such as

    initialization, channel bandwidth selection, channel scanning and acquisition,

    , and PID filter setting. Users also have access to all the relevant

    signal statistic information generated by the IC, post-Viterbi bit error

    rate(BER), uncorrectable Reed-Solomon (RS) packet count, signal strength,

    and signal quality indicator.



    One sample program with source codes are included in the driver package.

    The sample program demonstrate how to access the V4L and the device in

    DVB-T mode.



    For users who are not familiar with Linux & LinuxTV, please refer to 'User Guide Linux FC6-3' which

    details package & player installation step-by-step.



5.  Package Installation for Linux



    a. Install driver with source code

        Alternatively, you may compile and install the driver source code manually,



        1) In the folder 'IT9135_SRC', type the following command to compile & install it9135 DVB-T driver dvb-usb-it9135.ko.

            # make clean

            # make

            # make install



        2) Plug in the device and check the message to make sure the driver is work normally.

            # cat /var/log/messages



            log messages:



            dvb-usb: found a 'ITEtech USB2.0 DVB-T Recevier' in warm state.

            dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.

            dvb-usb: ITEtech USB2.0 DVB-T Recevier successfully initialized and connected.

6.  Driver uninstall

	To remove ITE's driver, input

	    make remove



	To delete .ko files, input

	    make clean



7. Remote Controller support

    To enable IR Remote Controller, the configuration settings in EEPROM  should be set properly

    The IR type supported is NEC or RC-5, the configuration is set in EEPROM.

    By default, The IR type for the Remote Controller shipped with 9135 USB dongle, is

    consistent with EEPROM setting.



    If the RC is acquired elsewhere, you should run ITE's EEPROMEdiotr in Windows to program the

    IR type field properly.



    RC key mapping table,

        The RC key mapping table is stored in af35irtbl.bin.

        A "Windows" tool IR_Editor.exe from Afa is available for users to customize the key mapping table.





8.  Known problems & limitations

    a.CPU architecture:

        Currently only x86 architecture is supported.

    b.USB support:

        Currently only USB2.0 is supported.

    c.Device VID/PID:

        0x048D/0x9005; 0x048D/0x9006.

    d.IR is supported and IRTable is named "af35irtbl.bin".

    e.Officially supported distributions:

        Linux Kernel - kernel 2.6.10 upward.



9. Future work

    USB1.1 support.
