First Claim
1. A method comprising:
- a video source device and a first video repeater device cooperatively authenticating the first video repeater device to the video source device;
the first video repeater device and first at least one video sink device cooperatively authenticating the first video sink device to the first video repeater device; and
the video source device and the first video repeater device cooperatively authenticating the first video sink device to the video source device;
wherein said cooperative authentication of the first video sink device to the video source device comprises;
said first video repeater device providing, to said video source device, a device key selection vector for the first video sink device.

Abstract
A video source device and a video repeater device cooperatively authenticates said video repeater apparatus to said video source device. In one embodiment, the authentication is performed using an identical authentication process a video sink device would authenticate itself to the video source device. The video repeater device augment the identical process identifying itself as a repeater device. The video repeater device also in cooperation with at least one video sink device authenticates the at least one video sink device. The video repeater device in turn, in cooperation with the video source device, authenticates the at least one video sink device to the video source device. In one embodiment, the video repeater device also in cooperation with another video repeater device, authenticates yet another at least one video sink device to the video repeater device. In like manner, the video repeater device, in cooperation with the video source device, authenticates the yet another at least one video sink device to the video source device. In one embodiment, the video repeater device includes topological information of the video sink devices among the authentication information provided to the video source device. Accordingly, video sink devices may be hierarchically organized to the video source device.
