https://lnkd.in/eKMeePJa D2X Multicast Broadcast Disaggregation System Architecture supports an SFN underlay RU Category (A) and SFN Wide Area RU Category (B), From perspective RU on a symbol-by-symbol basis under control D2X scheduler via eCPRI protocol messages D2X virtual frame (1000ms) is constructed. First VFS Bootstrap + L1 Signaling (1 + 2) time domain I/Q is sent to I/Q DAC, upconverted RF, PA. Then emitted antenna air interface aligned GPS 1PPS to begin D2X virtual frame. The D2X virtual frame (1000ms) shows highlighted (red) the virtual sub-frames with a mixture of D2X services for SFN underlay and the SFN wide area topologies. The remaining virtual sub-frames have only SFN wide area D2X services. The D2X scheduler eCPRI protocol messages for RU Type (A) sub-frames. The virtual sub-frame SS (3 + 4) is sent from cloud to RU D2X sites (1, 2, 3). Then all PRB for a symbol with D2X services (5) for wide area SFN are sent. Then RU generates three duplicate symbols for each sector (A, B, C) of SFN. Then for all VBP the PRB for D2X services (5) geo-targeted for SFN underlay is sent with eCPRI signaling to direct to a specific Site RU and sector. These are inserted by RU shown in the correct sector as signaled to complete a symbol. This process repeats for each symbol of a virtual frame with SFN underlay D2X services. If virtual sub-frame has only SFN wide area D2X services, then the SFN sectors are generated and the next step for insertion SFN underlay is skipped by D2X scheduler for each symbol of the virtual sub-frame. This is only an example the D2X scheduler, and algorithms are not specified in D2X standard. Only L1 signaling syntax and semantics for receivers (UE) and eCPRI messages to enable innovation using D2X harmonized 5G NR and aligned using O-RAN principles. #D2X #ORAN

I developed and open sourced a script that runs ffmpeg and uploads the result to an S3 bucket. By making this available as a service in Eyevinn Open Source Cloud you can benefit from this and use it to for example extract a section of a large video file without having to writing a single line of code. In this blog post I provide a step-by-step tutorial for this use case. https://lnkd.in/dxcsz2UJ

In this blog post I describe how you can setup an S3 compatible object storage service in Open Source Cloud. This service was added by the Open Source Cloud automated supply chain and made available as a service earlier this afternoon. You can try it out for free. https://lnkd.in/dGFvT5vm

Want to get started with using the ffmpeg-based transcoder and open source project SVT Encore but don't know really how? Check out this tutorial on how to setup a VOD transcoding pipeline based on SVT Encore in Open Source Cloud. Then if you decide this is something for you and want to bring it to your own infrastructure you can, or chose not to. It is up to you. https://lnkd.in/dCjktAKN

Example D2X OFDMA Multicast Broadcast D2X Virtual Frame 1000ms. Each Virtual Frame Consists of (N) Virtual Sub-Frames. Each Virtual Sub-Frame consists of (N) Virtual Spectrum Slices. A OFDMA Resource Unit (RU) Size = (24) Sub-Carriers. D2X Virtual Slices are (N) x RU. This is used to schedule OFDM resources (8) Virtual slices shown. With D2X Multicast Broadcast (One-to-Many) this OFDMA approach is new and very Flexible. https://lnkd.in/epjUJKRJ

Lumen: The Good, The Bad, and The Ugly Lumen is enjoying a Renaissance under new CEO, Kate Johnson. She recognized the hard truth that Lumen had too much debt and managed to sell the South American and European assets above fair value to Colt and one other player. Less widely known is that Lumen sold off its ILEC business to Brightspeed for $7.5 billion. In addition, she is focusing on fibre-to-the-home deployment as opposed to trying to protect legacy twisted copper wire assets. Many telecom CEOs are unable to make the hard choice of cannibalizing or selling slow growth PSTN services like POTs and DSL in order to deploy new, technologically more advanced services. But the stock market approves the strategy as far sighted. Furthermore, Johnson has recognized that Lumen should finally integrate its five networks into one. These five networks reflect purchases of distressed assets that previous CEOs made over 15 years ago, including Qwest Communications, Time Warner Telecom, Global Crossing, and others. Integration is estimated to slash network expenses by a billion USD a year. If Lumen has integrated these assets in a timely fashion, Lumen's shareholders would be about $15 billion dollars richer today. It would still have its international assets and be a global player. Kate Johnson is making Lumen's focus the AI industry. This is good marketing and investors are likely to buy it short term. Nonetheless, AI has all the marking of a gigantic bubble as the revenue potential of generative AI is limited and certainly not great enough to justify the massive investments in the sector. Large language models are simply gigantic nonlinear statistical models that ape whatever language samples are used to estimate them. Reasoning ability is extremely limited. If a model was estimated using Donald Trump's tweets, it would insist that the 2020 election was stolen and that he is the most oppressed man on the planet. This so-called AI is basically regurgitation. It will be sensible if trained on the Wall Street and New York Times or downright crazy if trained on the proceedings of the Flat Earth Society. It is likely Lumen will benefit from being a partner of the Digital Titans, but I suspect the growth benefit will peter out in a few years when AI undergoes its own crisis just like the bursting of the dotcom bubble in 2000. I would focus more on reducing head count as transport and transit services can be profitable, but only if the company is lean and mean. I wish Lumen the best of luck. #lumen #renaissance #integration #leverage #katejohnson #ai

Cord Cutters not seeking live TV certainly should be a red flag to cable companies. But more importantly, it should be a harbinger of doom for the off-air stations that broke the CATV market to begin with by demanding higher than justified rates. With the limited coverage area of UHF digital signals, local TV stations need the CATV and streaming markets to retain their customer base. Without that added base, advertising dollars will go down, resulting in increasing costs to the remaining CATV and streaming platforms; a continuing death spiral. Rural areas will be hurt the most, as they will lose reliable local news and weather sources. https://lnkd.in/g8P7Ae6b

The impact we can have with #BPS is immense and important for the United States. Recent NSSA report puts it in the trillions. And with #ATSC3 being deployed by other natuons, the opportunity is even bigger.

During my decades, yes decades, of being involved with the design, implementation, and configuration of network control and audio distribution people were always surprised by how vehemently I did not recommend making systems being connected to or requiring the “cloud” or Internet to function. I still have this opinion. Today is a day when I believe that some of the people to understand why systems need to be localized. Imagine if an airport paging and flight information display system stop functioning today. A theme park? Sports venue? Malls? Train & Subway systems? This also applies to home automation. I know that today’s CrowdStrike is likely not directly impacting the systems I have mentioned. The outages did show how the interconnected systems impact each other even when not directly involved. But Microsoft Teams or Zoom Rooms not functioning today are definitely an issue. The meeting is not starting Is the problem the AV hardware?
