With digital streams and do-not-copy-bits easily inserted into the stream, I was thinking it wouldn't be too burdensome to require advertisers to insert "commercial" bits, that signal the beginning and end of commercial advertisements. While there would be a variety of uses for such a bit, I would like to see an FCC mandate it to allow users to effectively enforce the FCC's own rule of not blasting the volume during commercial interruptions. With the bits inserted, the Tivo would know to lower volume levels to reasonable levels without interfering with program volume. Of course, this could be used to completely skip commercials,too I am sure big business would object, but isn't it about time for the FCC to step in in favor of the consumer? I mean we are required to subsidize DRM costs via the additional hardware required to be included in certain components (eg. Macrovision, HDCP, etc...), so why not throw the consumer a bone and allow them to benefit in this one area. Any thoughts?
