I also developed a simple lossless compression protocol for use in compressing telephone logs in the days when some phone switch manufacturers had to make do with a few 14MB data cartridge drives. I can tell you that my experience with data compression is also quite rudimentary.. Although probably somewhat more detailed than yours. As I have told you. I worked in the "Broadcast Industry' for most of my life.. Since I was 14. In the early-eighties I worked for a short period of time for a small Redwood City Company that developed Digital processing equipment for broadcast and government. Our research led to the issuance of several patents for the basis of the technology which commonly became known as Run-Length-Encoding. Of course, back then. RF Bandwidth was not our primary goal.. It was memory!! It was very very expensive at the time, and the project that we worked on required storing several thousand frames of NTSC video into RAM. I am even listed on the patent! Not that this has much to do with codecs currently being used. But you can't get away from the fact that neither company is using HM now, I don't know this as a FACT.. You keep saying it is a fact. But, I haven't seen any verifiable information to say one way or the other. (No, I don't consider your Bitter Anti-SIRIUS viewpoints as verifiable). (well, some would argue SIRI cannot without interfering with existing channels) Not interested in Chat Room Gossip and opinions.SIRI "states" a lot of things (as do you). Well, at least I have a link to the comanies web site to support what I say, while you my boy.. Well, you have a bunch or wild stories about interludes with On-Line Chat Room 14 year old boys who claim they have "modulation analyzers".. LOL!! Lee Abrams has publicly stated he expects to get to about 200 channels in all with "technology advances" (which can only be HM) and I believe you'll see that XM has this functionality before Sirius does, if XM's current engineering lead holds. All opinion.. Hmmm.. twenty or so more audio channels or 3 Video Channels.. Tuff to call that a engineering lead? PCSTEL
