How about a motherboard for an HTPC that enables me to eliminate my receiver, cable / satellite box, IR retransmitter, etc?
- Instead of built-in audio with line-out level outputs, grab some PCIe 8-pin GPU power from the PSU and use high-quality class-D amps to put out 5.1 or 7.1 audio. Use some of the expansion slot openings on the case for the speaker connections, with wires to internal terminals. Existing PCIe cards do this, but it would be better if it could be smaller and more integrated.
- Include up to 4 HDMI inputs that are switched to a single output shared with the onboard GPU. Inject overlays onto the other inputs when you need to show something like a phone caller ID, IR command, etc. Support audio decoding (including from the GPU signal) for Dolby True HD, DTS Master Audio, 8-channel PCM and the other Blu Ray formats.
- Include inputs to support XM or Sirius, with on-screen control using the switched HDMI overlay display
- Include 1 or 2 digital and analog audio inputs for legacy audio devices
- An IR output capable of controlling several components.
- An IR input for receiving commands from other vendors' Universal Remotes
- An RF remote control receiver (or BT?) that links up with the IR subsystem
- Onboard or daughter card satellite, cable (w/ two-way OCUR or whatever that's called) or terrestrial tuner(s) with a single shared COAX connection
- Onboard SSD (does not need to be super-performance) with a quick-boot secondary bootup that runs something like XBMC or better, but augmented to suppor the rest of the capabilities of this MB.
- Gb LAN connect
- HDMI 1.4-compatible output processing (configurable as video only w/ audio going to internal audio card, or combined video / audio). And for REALLY high-end, transform 3-D HDMI signals into two separate 2-D HDMI outputs such as to drive two projectors with polarized light per a recent THG article. Also use this output processor to use the HDMI to transmit and receive RC signals from other components.
- Digital audio out and/or analog audio outs for sending to other receivers for multi-room
The trick with this is probably the cooling and the licensing. If you get rid of all of the crap, you can probably fit a few HDMI connectors, a few USB ports, a LAN port, IR ports and one or two digital audio ins and outs into the back panel. Then half-height PCI slot breakouts can provide speaker-level, line-level, digital audio, sirius or XM radio I/O connections to the MB. With some cooperation from a case manuf, the speaker-level card manuf (noted in past HTPC article on THG), a Sirius tech manuf, an XM radio tech manuf, and a tuner manuf like Hauppauge, you can integrate all of this into a single board that stands alone and can actually look good as an HTPC.
A board like this with a PCIe-X16 slot for a high-power GPU and fully-loaded for good-quality 7.1 speaker out, cable card, switched-input HDMI and integrated RF/IR would be worth something... and would be totally unique in the consumer A/V space.
