Η αναβάθμιση του δημοφιλούς προτύπου διασύνδεσης συσκευών HDMI (το οποίο έχει παγιωθεί την τελευταία δεκαετία ως ένας από τους πιο κοινούς τρόπους μεταφοράς δεδομένων εικόνας και ήχου) είναι γεγονός και η ανακοίνωση της έκδοσης 2.0 έρχεται πάνω στην ώρα που εξαπλώνεται η νέα γενιά των Ultra HDTVs.
Οι δυνατότητες πλέον είναι περισσότερες, με την πιο αξιοσημείωτη τη χωρητικότητα του εύρους ζώνης που φτάνει τα 18Gbps, κάτι που σημαίνει πως εάν υπήρχε περιορισμός για σάρωση με ρυθμό 30Hz σε τηλεοράσεις υψηλής ευκρίνειας ανάλυσης 4K, τώρα η ταχύτητα σάρωσης έφτασε στα 50/60Hz, με την κίνηση της εικόνας 4Κ να είναι άψογη.
Άλλα πλεονεκτήματα του HDMI 2.0 συμπεριλαμβάνουν την μετάδοση έως και 32 ηχητικών καναλιών, δυνατότητα έξυπνου «συγχρονισμού» χειλιών και ομιλίας στις ταινίες, καθώς και πρόσθετες λειτουργίες σχετικές με τον χειρισμό συσκευών μέσα από άλλες (CEC). Φυσικά, η έκδοση 2.0 παραμένει συμβατή με τις προγενέστερες εκδόσεις, 1.3 και 1.4, ενώ σημειώνεται πως οι νέες θύρες θα είναι συμβατές με τα υπάρχοντα καλώδια, αρκεί να είναι Category 2. Επιπλέον, θα υποστηρίζεται ο λόγος πλευρών 21:9 και το audio sampling frequency είναι πλέον στα 1536kHz.
Ήδη, το νέο πρότυπο HDMI 2.0, έχει προκαλέσει την ανησυχία καταναλωτών και κατασκευαστών, για το εάν όντως οι υπάρχουσες τηλεοράσεις τύπου UHDTV που βρίσκονται στην αγορά, θα μπορούν να την υποστηρίξουν. Θα μάθουμε τα σχέδια των εταιριών κατά τις επόμενες ημέρες.
Το θετικό όλων είναι ότι τα βύσματα παραμένουν τα ίδια και ο κόσμος θα χρειαστεί να αλλάξει μόνο το καλώδιο HDMI και όχι την συσκευή. [via]

BERLIN, Germany – September 4, 2013 – IFA 2013 – HDMI Forum, Inc., a non-profit, mutual benefit corporation, today announced the release of Version 2.0 of the HDMI Specification. This latest HDMI Specification, the first to be developed by the HDMI Forum, offers a significant increase in bandwidth (up to 18Gbps) to support new features such as 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution; 32 audio channels; as well as dynamic auto lip-sync and extensions to CEC. The complete Version 2.0 of the HDMI Specification is available to Adopters on the HDMI Adopter Extranet. HDMI Licensing, LLC will host a press conference to discuss the new features of the HDMI 2.0 Specification at IFA 2013 in Berlin on Friday, September 6 at 12:00pm in the TecWatch Forum area of Hall 11.1.
Version 2.0 of the HDMI Specification, which is backward compatible with earlier versions of the Specification, was developed by the HDMI Forum’s Technical Working Group whose members represent some of the world’s leading manufacturers of consumer electronics, personal computers, mobile devices, cables and components. The HDMI Forum currently has a membership of 88 companies.
“The introduction of the HDMI 2.0 Specification represents a major milestone for the HDMI Forum,” said Robert Blanchard of Sony Corporation, president of the HDMI Forum. “Our members collaborated closely to take the highly successful HDMI Specification to the next level by expanding audio and video features for consumer electronics applications.”
The HDMI Forum has chosen HDMI Licensing, LLC to be the Agent to license Version 2.0 of the HDMI Specification. In this role, HDMI Licensing, LLC will provide marketing, promotional, licensing and administrative services, as well as education on the benefits of the HDMI Specification to adopters, retailers, and consumers.
“We are pleased to continue our work in supporting the HDMI Adopter base as well as the entire HDMI ecosystem,” said Steve Venuti, president of HDMI Licensing, LLC. “Adopters can now continue to develop new product functionality over the HDMI interface as well as look to HDMI Licensing, LLC as their single contact for all their licensing and administrative needs.”
Version 2.0 of the HDMI Specification does not define new cables or new connectors. Current High Speed cables (category 2 cables) are capable of carrying the increased bandwidth.
The HDMI 2.0 Compliance Test Specification (CTS) is expected to be released before the end of 2013.
