Katznelson Public Comments in Rulemaking Proceedings http://works.bepress.com/rkatznelson/47 http://works.bepress.com/rkatznelson/47 Wed, 03 Sep 2008 13:50:10 PDT This note addresses the impact of broadband return loss of frequency agile modulators when combined through headend combining networks. In particular, the effect of less-than-ideal output return loss values are examined and it is shown that even under the worst case conditions, a broadband return loss of 10 dB produces only small reductions in isolation that still permit cable operators to meet their headend combining specifications.

It shows that the impact of a proposed change is negligible and that the advantages far outweigh the perceived disadvantages of adopting such a change. Ron D. Katznelson Standards Setting Organizations - Comments and Submissions http://works.bepress.com/rkatznelson/45 http://works.bepress.com/rkatznelson/45 Wed, 03 Sep 2008 12:43:24 PDT This submission supported Broadband Innovations' (BI) opposition to relaxing the Out-of-Band Noise and Spurious specifications in QAM downstream transmission of Edge-QAM ("EQAM") devices. The specifications relaxation was proposed by a consortium of equipment vendors who called it the Joint Proposal for Self-Aggregate noise and spurious ("JPSA"). This note explains why the adoption of the JPSA would strip CATV systems from having sufficient operational noise and interference margins. Post submission note: Despite the overwhelming majority of the Working Group's acceptance and recommendation of the JPSA, CableLabs' Technical Board voted to accept BI's proposal and to reject the JPSA.

It contains responses to a proposed changes offered by European proponents. This note addresses the in-channel (Active Output Channel) return loss requirements and the 'Other Channels' spurious and noise requirements. Ron D.

It utilizes advanced Digital Signal Processing ("DSP") methods for effecting low cost broadband access control signal security compatible with most addressable converters in use today. It provides economically viable option for cable system operators to provide their subscribers with a truly "subscriber friendly" cable service while distributing scrambled video signals on the cable plant and avoiding the need for set-top descramblers.Unlike existing "single-channel-at-a-time" descrambling technologies, the DBD technology simultaneously descrambles and provides all authorized channels in the clear by means of broadband selective coherent injection at RF. It enables subscribers to enjoy all the features of their cable ready TVs and VCRs in a whole-house service, including built-in VCR programming functions, remote controls, watching and recording from different scrambled channels simultaneously or consecutively, and viewing multiple channels at once (picture-in-picture). Furthermore, the DBD devices pass into the home all other unprocessed channels including digital compression signals, thereby allowing compatibility with future digital transmission. Ron D.
