Bidirectional Cable
Bidirectional Cable
Is a HDMI cable bidirectional and does it carry the sound signal as well?
My uncle's tv's sound won't play through the Surround Sound speakers.
The DVD is connected to the speakers and the sound of DVDs plays through the speakers.
The only connection between the TV and the DVD player is the HDMI cable.
Should that be enough to transmit sound from the TV to the speakers (through the DVD player) or does he need another cable?
The HDMI specs support standard NTSC and PAL, enhanced, and high-definition video formats (720p, 1080i, and 1080p up to 60Hz), plus 8-channels, of 192kHz, 24-bit uncompressed digital audio on a single HDMI cable. And still, there is bandwidth to spare to accommodate future enhancements and new requirements.
Note that support for 1080p/60Hz is not mandatory and therefore equipment manufacturers may opt to implement only 1080i.
Also, beginning with HDMI ver. 1.2 (released August 05), HDMI now includes support for One-Bit Audio format used in SACD (SuperAudio CD's) Direct Stream Digital.
