Gadmei USB TVBox UTV380

A Small USB based analogue capture device using EM2860 and Xceive xc2028 chip Tuner.

It is currently not supported under Linux.

Overview/Features

  • It has Television and S-Video inputs via a Two separate 3.5mm tail cables
  • It falls under V4L's "Em28xx devices" category (being based upon an EM2860 usb bridge)

Components Used

  • Empia EM2860 (USB video bridge)
  • Empia EMP202 (AC'97 audio processor)
  • NXP/Philips SAA7113 (video decoder)
  • Xceive XC2028ACQ (Analog chip tuner)
  • 24C04 (EEPROM)
  • HCF4052 (4-channel Analog multiplexer)

Other Pictures

Current Status

  • Currently it works after patching the v4l-dvb.
  • Need to test the sound and Composite inputs.
  • Will release the patch soon.
  • I need help on releasing this as a Patch upstream.
  • Also I need help to upload some real pictures of the device into this Wiki( I can't figure it out till now(BAD ME).
  • Anybody interested can contact me jeevas.v AT gmail.com

To make it work

I have done these changes to make it work.

  • 1. extract the Xcieve firmware for xc2028 and copy to /lib/firmware as mentioned in the em28xx page.
  • 2. extract the latest v4l-dvb source as mentioned in the em28xx page.
  • 3. go to v4l-dvb/linux/media/video/em28xx folder.
  • 4. edit em28xx.h file and add the device:

. . 

 #define EM2870_BOARD_REDDO_DVB_C_USB_BOX          73
 #define EM2800_BOARD_VC211A			  74
 #define EM2882_BOARD_DIKOM_DK300		  75
 #define EM2860_BOARD_GADMEI_UTV380          76

. .

  • 5 edit em28xx-cards.c and add the card in card definitions

. . . 

 [EM2860_BOARD_GADMEI_UTV380] = {

.name = "Gadmei UTV380", .tuner_type = TUNER_XC2028, .tuner_gpio = default_tuner_gpio, .has_dvb = 0, .decoder = EM28XX_SAA711X, .input = { { .type = EM28XX_VMUX_TELEVISION, .vmux = SAA7115_COMPOSITE2, .amux = EM28XX_AMUX_VIDEO, }, { .type = EM28XX_VMUX_COMPOSITE1, .vmux = SAA7115_COMPOSITE0, .amux = EM28XX_AMUX_LINE_IN, } } }, . . .


And also add the card's usb id in the list if it is not already there. . . 

 { USB_DEVICE(0xeb1a, 0x50a3),

.driver_info = EM2860_BOARD_GADMEI_UTV380 }, . .


  • 6. Edit em28xx-core.c and make sure that the AC97 audio processor is properly detected. In this case I have to add one more vendor based on the dmesg output.

. .

/* Try to identify what audio processor we have */ if (((vid == 0xffffffff)||(vid == 0x83847650)) && (feat == 0x6a90)) dev->audio_mode.ac97 = EM28XX_AC97_EM202; else if ((vid >> 8) == 0x838476) dev->audio_mode.ac97 = EM28XX_AC97_SIGMATEL; . .

  • 7. Then execute the following commands to build and install the kernel modules.
 sudo make distclean
 sudo make menuconfig (Due to some error I have to disable one of the modules in the list to get past the compilation).
 sudo make
 sudo make install
  • 8. After this restart your machine, plugin your device and start your favourite tv app and enjoy.
