Aggiornamento.
Sulla mia vecchia tv Philips LCD 32" del 2007 720p tuner digitale terrestre e 2 x porte HDMI
ho collegato i seguenti 2 adattatori HDMI :
. Cobra Fly, utilizzato per il mirroring tra cellulari/tablet Android e TV tramite lo standard Miracast
. Netgear PTV3000, utillizzato per il mirroring tra PC con Microsoft Windows e TV tramite Intel WiDi
Ora anche la mia cara e vecchia tv e' diventata ...una Smart TV !
Cobra Fly

Fly presenta la stessa forma di un “dongle” Android TV, misura 84,3×31,3×9,3 mm, si collega direttamente a una presa HDMI grazie alla spina integrata e si alimenta da una presa USB del TV o da un alimentatore sempre USB in grado di fornire almeno 0,5-1 Ampere di corrente.
Il chipset Cortex-A9 RK2928 con frequenza di lavoro di 1 GHz, abbinato a un modulo RAM DDR da 256 MB e a una Flash da 128 MB, permette di elaborare le informazioni che compongono le immagini e i suoni inviati dal device mobile con buona precisione. Il modulo Wi-Fi supporta bitrate fino a 8 Mbps (a 1080p e 720p) in un range massimo di 10 metri che si riducono a 6 durante lo streaming video.

Netgear PTV3000
=================

The new Push2TV Wireless Display Adapter supports wirelessly transmitted image display in up to 1080p full HD video resolution and 5.1 surround sound audio, so you can enjoy great quality movies, music, photos or any website on your big screen TV straight from your mobile devices. About one-third the size of its predecessor, PTV2000, and about the same length and width of a credit card, the Push2TV adapter PTV3000 can be conveniently placed in most home theater environments without adding more clutter. It is an ideal entertainment accessory for any Intel WiDi or Miracast compatible laptop, tablet or smartphone – even on the go.

Netgear PTV3000 Teardown
=========================

The PTV3000 is the third generation of the company's streaming media adapters, which support Intel's WiDi protocol (I discussed WiDi in a September 2012 feature article). The PTV1000 implemented up-to-720p WiDi v1.0, whereas the PTV2000 and PTV3000 comprehend the newer 1080p-capable WiDi specification variants. The PTV3000 is substantially more compact than its predecessor, and a firmware upgrade enables it to also support the WiDi-derived Miracast protocol (which I covered in some detail a few weeks ago).

I could have pried the tops off the Faraday cages, but this action would have rendered the PTV3000 unusable; I had hoped to keep it functional for future hands-on testing purposes. Fortunately, the WikiDevi site came through, as it has many times before. In addition to directly providing me with a partial parts list, it supplied a link to the FCC certification database page that served up under-metal shield photos.
Underneath the smaller shield on the left is an Atheros AR9374 dual-band 802.11a/b/g/n Wi-Fi controller (PDF). The larger shield to the right encompasses two notable ICs; Cavium's PureVu CNW6611L system SoC, and a SDRAM. The FCC photos reveal the memory's manufacturer: Hynix. But they're insufficiently clear to enable me to discern the product name portion of the package marking, therefore the DRAM density. Cavium's CNW6611L system block diagram strongly suggests, however, that it's a DDR3-technology memory device.
