Google Chromebit: Η νέα προσέγγιση στο Chrome OS

Recommended Posts

[NEWS_IMG=Google Chromebit: Η νέα προσέγγιση στο Chrome OS]http://www.hwbox.gr/images/news_images/google.jpg[/NEWS_IMG] Η Google μας δίνει έναν ακόμα λόγο για να προτιμήσουμε το Chrome OS, με ένα νέο dongle το οποίο συνδέεται στη HDMI θύρα της τηλεόρασής μας.

Το νέο dongle με την ονομασία Chromebit έχει όλες τις απαραίτητες βάσεις για να τρέξει το λειτουργικό σύστημα της Google, Chrome OS. Εφοδιάζεται με ένα Rockchip 3288 System on Chip (SoC) και συνοδεύεται από μνήμη RAM 2GB ενώ ο αποθηκευτικός χώρος που μπορούμε να χρησιμοποιήσουμε ανέρχεται στα 16GB. Παρά το μέγεθός του, το dongle διαθέτει θύρα USB 2.0 για περιφερειακές συσκευές εισόδου/εξόδου και αποθήκευσης, υποστήριξη ασύρματου δικτύου WiFi ac, ενώ το υποσύστημα γραφικών είναι το τετραπύρηνο ARM Mali 760.

Η σχεδίαση του dongle δεν καταφέρνει να ξεχωρίσει, όμως είναι αρκετά λειτουργική αφού μπορεί να περιστραφεί ώστε να μην εμποδίζει το πίσω μέρος της τηλεόρασης. Η συσκευή θα κατασκευάζεται από την ASUS και θα έρθει με προτεινόμενη τιμή τα $99 σε ασημί, μπλε και πορτοκαλί το καλοκαίρι.

ουτε 264 βλεπω ουτε 265 στα σπεκς

[h=3]10 characteristics and 5 advantages of RK3288, the latest generation chip [/h]

6. Perfect Play 4Kx2K H.265 Video

Pixel of 4K video is 4x of the 2K video. Therefore, image quality has greatly been improved, and a visual effect beyond imagination is achieved. H265 is an updated video coding and decoding criteria, and upgraded version of H264. Under the same condition of image quality, compression rate of H265 reaches twice that of H264.

This will not save storage space, but also greatly lower bandwidth requirement for online video. RK3288 is equipped with a powerful, 10 bit H265 hardware decoder supporting 4K2K, 60 frame per second. That can easily decode H265 video at 100M bit stream.

7. 4Kx2K HDMI2.0 Output @60fps Supported

When 4K2K and H265 technology are available, we need better technical conditions to embody it on TV. HDMI2.0 is just what we want. HDMI2.0 is the updated HDMI standard. This is the only version supporting display at 4K2K 60 frames per second. RK3288 is currently the only Android STB chip supporting this technology and in mass production.
