`    esponsive Brief, the purpose of the buffers    Patent,
`
`including the user-side buffer, is to ensure a steady flow of media for continuous playback. The

`disclosure states:

`
`range in this process, because the size of the individual data elements in the buffer can vary. This
`
`consequence yields the “about.”
`
`Depending on the encoding scheme, there are typical, known bounds to the variation
`
`between bitrates in complicated / high bitrate portions of the media, such as the “action scenes”
`
`versus less complicated / low bitrate portions of the media, such as still scenes. The differential is
`
`a result of the encoding and is known to a POSITA, or easily determined from the specification
`
`for the encoding scheme or a sampling of typical content so encoded. This is the basis for the
`
`variability required in the “about a predetermined number of media data elements,” and it is a
`
`well-understood variation.
`
`Google makes the argument that the number of media data elements stored in the buffer
`
`is not necessarily related to the size of each element. This may be true if one is free to arbitrarily
`
`shrink the encoding, but this directly reduces reproduction quality. In the real world, where
`
`quality of the presentation is also    , the size and number of elements are
`
`obviously interrelated, as the entire purpose is to maintain a buffer sufficient to avoid running out
`
`of media due to irregular reception, while maintaining the highest quality possible. This is why

`
`media does not reflect the ordinary meaning of the word “source,” but rather a special, limited

`
`Google points to disclosures about theoretical highest speed of a connection, actual
`
`highest speed of a connection, and average speed of a connection. These are all beside the point
`
