Cisco TelePresence - more detailed specs and questions
I am currently conducting a light research into various video-conferencing systems and would love to know a little more about Cisco TelePresence video-collaboration solutions.
I have read the on-line publications made available by Cisco, but have a few remaining questions.
Following is the list of such questions, should you find yourself being able to answer any of them - please do net hesitate to do so:
Q. What is the frame rate of a 1080p video stream when it is being transmitted at no greater than 5Mbps bandwidth consumption?
Q. What is the maximum possible frame rate for a 1080p video stream?
Q. Given the 5 Mbps bandwidth consumption limits, what is the latency (without taking into account the underlying network latency) to encode and then decode the 1080p video stream at 25 fps?
Q. For the purposes of subjective visual evaluation - are there any downloadable images such as a single frame (1:1 screen-shot) of the 1080p video stream transmitted at 5Mbps and 25FPS?
Q. Security-wise ? what kind of encryption (if any) is being used to encrypt the video streams and how interoperable such encryption systems happen to be? For instance, are the encryption keys communicated in accordance with certain protocol/standard or is the process specific to Cisco products?
Q. Has anyone (formally or otherwise) tried to interoperate Cisco Telepresence with other video-streaming solutions (e.g. Conference-XP, VLC, etc.)? If, so what were the results?
Q. Do Cisco Telepresence systems support multicast traffic (e.g. one source / many recipients idiom).
Re: Cisco TelePresence - more detailed specs and questions
also, just have 1 more question:
Q. In case if someone (i.e. a 3rd party software developer) was prepared to integrate their own video-streaming solutions (e.g. VLC, Conference XP, AccessGrid, etc.) with Cisco's Telepresence systems - is / will be there any way to obtain necessary technical documents regarding the functionality of Telepresence systems in order to achieve the desired interoperability?
To start with, such interoperability would be done at the very "basic" level: e.g. being able to see Telepresence's video streams in say VLC or AccessGrid or some other system and then may be being able to transmit video streams from VLC or similar in a format that allows Telepresence system to see the 3rd party content.
