1.    All entities MUST support H.264

Are you in favor of this option [Yes/No/Acceptable]: YES

2.    All entities MUST support VP8

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:

Interoperability with installed base is critical.  Interoperability should not requires additional burden such as deploying a farm of transcoders.

3.    All entities MUST support both H.264 and VP8

Are you in favor of this option [Yes/No/Acceptable]: Acceptable.

Do you have any objections to this option, if so please summarize them:  Supporting of H.264 is essential for interoperability with installed base.

4.    Browsers MUST support both H.264 and VP8, other entities MUST support at least one of H.264 and VP8

Are you in favor of this option [Yes/No/Acceptable]: Acceptable.

Do you have any objections to this option, if so please summarize them:  Supporting of H.264 is essential for interoperability with installed base.

5.    All entities MUST support at least one of H.264 and VP8

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  Non-support of H.264 causes an enormous burden on the Enterprises to leverage their current video deployment. Enterprises want to add browser-based apps but as a natural extension of their current deployment. Asking them to buy/deploy/manage a farm of transcoders does not allow an seamless extension to their deployment.

6.    All entities MUST support H.261

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:

7.   There is no MTI video codec

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them: Interoperability necessary.

8.    All entities MUST support H.261 and all entities MUST support at least one of H.264 and VP8

Are you in favor of this option [Yes/No/Acceptable]:  NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base and provides high quality experience.

9.    All entities MUST support Theora

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  Interoperability with installed base required

10.    All entities MUST implement at least two of {VP8, H.264, H.261}

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base and a high quality experience.

11.    All entities MUST implement at least two of {VP8, H.264, H.263}

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base and a high quality experience.

12.    All entities MUST support decoding using both H.264 and VP8, and MUST support encoding using at least one of H.264 or VP8

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base.

13.    All entities MUST support H.263

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:

14.    All entities MUST implement at least two of {VP8, H.264, Theora}

Are you in favor of this option [Yes/No/Acceptable]:  NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base.

15.    All entities MUST support decoding using Theora.

Are you in favor of this option [Yes/No/Acceptable]: NO.

Do you have any objections to this option, if so please summarize them:  does not assure H.264, which is necessary for interoperability with an installed base.

16.    All entities MUST support Motion JPEG

Are you in favor of this option [Yes/No/Acceptable]: NO.
