NSCC Executive Summary CBG Communications, Inc. <br /> • Access Signal Origination via Fiber Optic Connections <br /> These connections from fixed locations throughout the NSCC area needed to continue in <br /> order to provide programming from the various local governments and school districts to <br /> CTV to be further distributed on the access channels. However,these connections are <br /> currently provided in a SD (Standard definition)format. In order to meet the needs <br /> assessed,they will need to be converted to an HD (high definition)format. This will <br /> require upgrading the equipment on both ends (both at the local government and school <br /> district signal origination site and at the CTV receive site) in order to enable HD <br /> transport. <br /> Similarly,the multiplexed, aggregated, feed from CTVS' offices to Comcast over the C- <br /> RAN, currently provides signals in an SD format. Here again,the equipment on both <br /> ends (at CTV and at Comcast's Roseville headend)needs to be upgraded in order to <br /> provide HD transport. <br /> In each case,this includes upgrading encoders and decoders (for a higher HD encoding <br /> rate) as well as optical transport equipment(HD requires a higher transfer rate, and <br /> potentially some different multiplexing gear so additional colors of light may be utilized) <br /> in order to enable HD signal transport. <br /> • Upgrade of the HFC I-Net or Replacement with an Alternative <br /> The HFC I-Net has experienced both some reliability and maintenance issues, as more <br /> specifically detailed earlier in this Executive Summary. Since remote video origination <br /> also needs to be able to facilitate HD transport,the HFC I-Net will need to be upgraded to <br /> provide highly reliable, higher capacity connections. This would enable remote <br /> origination in HD for productions provided through use of each of the remote production <br /> trucks, or the use of portable"mini-mobile"production equipment(the encoders <br /> currently in use by the trucks, as well as that recommended for the mini-mobile unit, <br /> would need to be upgraded to HD transport as part of each of these solutions). <br /> One possible method to meet the data transportation needs currently being fulfilled by the <br /> HFC I-Net is to implement a high capacity DOCSIS 3.0 cable modem system that would <br /> xvi <br />
