Especificaciones de cables HDMI

[Carlos Alanis]

Una pregunta:

¿ TODOS los cables HDMI transfieren Video a 1080P y audio digital 7.1 sin compresion ?
¿ Es una cuestión solo de los conectores de i/o de los equipos o el cable tambien tiene sus especificaciones ?
No he visto nada de esto en las especificaciones de los sitios clasicos de Best Buy o Circui city, pero en los comentarios de los clientes sí lo mencionan, ¿ que onda ?

No todos....

Lo que he encontrado es que una de las versiones mas actuales de cables HDMI, son los que cumplen con la Version del protocolo que usa NDMI 1.3a Categoría 2.
Lo que indica que puedes pasar 1080P/24fps, LPCM 24/192KHz en 8 canales, Dolby Thrue HD, DTS HD Master, Deep Color o x.v.Color, HDMI CEC para el control de los equipos via esta interfase, todo esto al mismo tiempo.
Esto da un ancho de banda un poco mas a 10Gbps.
Aquí pongo una lista de las versiones de HDMI y sus cualidades, creo que una de las pocas marcas como Sony, en su producto en el empaque menciona de forma segura que es un cable para HDMI 1.3a Categoria 2 de alta velocidad.

Por cierto en los cables de Monster para HDMI, tienen algunas cosas que las menejan como merkadotecnia para venderse mas

A 36-bit support is mandatory for Deep Color compatible CE devices with 48-bit support being optional.[87]
B Maximum resolution is based on CVT-RB blanking which is a VESA standard for non-CRT based displays.[88] Using CVT-RB blanking 1920x1200 would have a video bandwidth of 3.69 Gbit/s and 2560x1600 would have a video bandwidth of 8.12 Gbit/s.
C Using CVT-RB blanking would have a video bandwidth of 8.12 Gbit/s.
D Using CVT-RB blanking would have a video bandwidth of 7.91 Gbit/s.
E Using CVT-RB blanking would have a video bandwidth of 7.39 Gbit/s.
F Even for audio bitstream formats that a given HDMI version cannot transport it may still be possible to decode the bitstream in the player and transmit the audio as PCM with no loss of quality.
G CEC has been in the HDMI specification since version 1.0 but has only begun to be used in CE products with HDMI version 1.3a.
H Playback of SACD may be possible for older HDMI versions if the signal source (such as the Oppo 970) converts to LPCM. For those receivers that have only PCM DAC converters and not DSD this means that no additional resolution loss occurs.
I Large number of additions and clarifications for CEC commands. One addition is CEC command allowing for volume control of an AV receiver.
