[Cloud Browser] Some comments on the Architecture chapter

Hello Alexandra and others:
I have some comments on the Cloud Browser Architecture [1]:

*        In the section on Terminology, what is the difference between the "TV UI zero client approach" and the "Cloud browser"? The description seems to be much the same, but perhaps there are subtle differences? If there isn't, I'd keep one of these and add the other to the "Also known as" cell of the one retained .

*        Also in the section on Terminology, Out-of-band media and In-band media are defined as the principal terms, with Double Stream Approach and Single Stream Approach, respectively, placed as secondary under "Also known as". However, in later sections the terms out-of-band and in-band are not used and the double stream and single stream terms are used extensively. Thus, I would suggest that the placements be reversed and that double/single stream be the primary terms and the out-of-band/in-band be placed under "also known as".

*        Depending on the resolution of the above points, the section "Evolution of the TV UI" may need to be updated. It would be best if the same and principal term were used throughout rather than use every variant (in "also known as") in different sentences. (The idea of having "also known as" seemed like a good one at the time, but it can be very confusing if the primary terms are not used consistently throughout the document.)

*        In the section "Architecture", in the table with cell [Single Stream, Cloud Player], second bullet , I added the word "original" as highlighted: "This Scenario implies decryption capabilities of the Cloud Environment. The client doesn't need to support the original source encryption."

*        In "Architecture" in the cell Double Stream, I think the following change (highlighted in red) should be made: "In this approach there are different ways of content injection. However, in both cases the content UI is rendered in the Cloud and is sent to the client in two separate streams -an UI stream and a media stream." I made the change on the page.

*        Finally, in Double Stream Local Player Approach Functions, I did not understand the sentence following the table "Cloud Environment functions notice: also the UI enryption in case of sensitive video elements might be applied. Here also the video decryption function might be required." What is it trying to say?  Maybe these could be added to the table with the words "(if required)" or "(optional)", as appropriate.

I also made some minor editorial corrections (grammar, spelling etc.) throughout the text of this chapter, too trivial to describe in detail.
Thanks,
Nilo
