In today's MPTF meeting, we seemed to be converging on the idea that CT2 (which specifics a lower limit for average bit rate), is not necessary. The reasoning behind this is that a client that plays ABR content is choosing the content to play based on quality level and bandwidth already. Specifying a minimum bandwidth suggests a target, but if that minimum bandwidth can't be delivered, there's likely nothing the client can do to force more bandwidth. Therefore, the options are to buffer content (possibly while stopping playback) or generate an error condition. Also, there is no common way to specify quality across different implementations. Unless and until we can resolve these issues, there seems to be little support for CT2. I am hereby soliciting comments on this issue. We will discuss this in more detail during next week's call and either produce viable use cases that meet our requirements, or remove the requirement. Thanks, -Clarke
