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

https://lnkd.in/efWpqBMs RAN slicing is one of the important new features of 5G networks; it makes differentiated services possible, enabling new features for customers and network monetization opportunities for operators. The 3rd Generation Partnership Project (3GPP) specifications define the slice mechanism, but they don’t say anything about how to implement the slices. Also, we haven’t seen many production-level, real-world implementations of RAN slicing, perhaps because 5G business roll-out is complex. We have done research and produced new results related to RAN slicing and I’d like to enumerate a few that will make it easier for operators to use it with Microsoft Azure.

While in most cases it is not a problem to have a CDN pull directly from a FAST Channel Engine in Open Source Cloud there are use cases where you need to push the channel to another live origin. One use case is that you want to just-in-time repackage to HLS and MPEG-DASH. Find a step-by-step guide in this tutorial on how you setup a bridge between FAST channels in Open Source Cloud and origin in AWS: https://lnkd.in/dxnvWzGr

D2X is a New Multicast Broadcast RAN Aligned with 5G NR for future Interworking https://lnkd.in/eUgyWWA2 D2X OFDM Frames are based on Resource Block (RB) of (24) Sub-carriers in Frequency and supports Bandwidths shown table below. The (24) is LCM of 3, 4, 6, 8, 12 the spacing frequency of the (5) scatter pilot patterns selectable. For the best spectrum Efficiency and Economics, a 24 MHz D2X Carrier shown table is shared by Broadcast Virtual Network Operators (BVNO). This could be comprised of (4) 6 MHz or (3) 8 MHz continuous broadcast carriers. With D2X Baseband CU/DU in Cloud and sent to Shared RU and antennas at transmitter / cell sites makes economics for operators attractive. A D2X 24 MHz UE will work on a global scale. Just as a 20MHz LTE UE was successfully deployed by MNO using (5, 10, 15, 20) MHz carriers. The graphic below shows 24 MHz D2X UE and support for reduce service capable IoT, Wearable with extended battery requirements. The D2X thesis is such a Multicast Broadcast RAN harmonized with 5G NR (MBS) with diverse Single Frequency Network Topologies D2X which could overlay and interwork offload 5G traffic or complement with converged services in future. D2X is currently being considered (Studied) by ATSC standard organization https://www.atsc.org/ and interested 5G MNO and or 5G Vendors are welcome to give input to consider feasibility for broadcast and or IMT bands. D2X is designed using O-RAN cloud-native principles. The Terrestrial Broadcast RAN architecture has not changed in 75 years until emergence of O-RAN.

Customer feedback and reception have been overwhelmingly positive since we launched our Gen-IC Cloud Intercom service at the start of the year. Transitioning production workflows from on-premises to cloud-based tools is not always smooth, and getting crews and personnel fluent with new systems can come with many teething challenges. However, one of the main pieces of customer feedback we get is how intuitive Gen-IC is to use especially with the self-serve SkyPort portal. Moreover, the users of the system continue to work with the same virtual clients or physical panels (hybrid systems) that they have come to love for many years. This results in much lower deployment costs as no user training is required. Gen-IC is our first product venture into managed cloud services, and it’s hugely rewarding to hear that it is enabling our customers to save time and money, making productions as efficient as possible.

https://lnkd.in/eMMkBc_v The concept of rApp is defined by Open RAN. The rApps are software application designed to run on the Non-Real Time RAN Intelligent Controller (from now on the Non-RT RIC) to realize different RAN management and optimization use cases in an automated way, with control loops on a time scale of one second and longer. Ericsson extends the scope of the rApps to purpose-built RAN in addition to O-RAN definition. Ericsson defines four main rApp categories: Network evolution rApps Network deployment rApps Network optimization rApps Network healing rApps #rAPP #RAN #Automation #ORAN

Live-event testing is particularly critical since live programming introduces distinct variables that aren't present in other types of streaming content.   https://lnkd.in/gT95Yy5d Issues could occur with firewalls adding jitter and interruptions to media flows. Outages can happen if the network overloads. And there are challenges adapting between IP media domains such as from unicast to multicast. It can often be tricky to determine the source of quality issues in your IP media network.   Maintaining consistent content quality across varied network conditions and regions is paramount. Having a media specific toolkit to manage these challenges can be key.   Net Insight provides the highest performing, most open video transport and media cloud technology around. We are trusted by 500+ global customers with AWS, The Switch, BBC, Tata Communications, NBC and France 2 among them. You may not know us, but we can guarantee you have seen the results of what we do, every day.   #liveeventstreaming #livevideocontribution #contributionlinks #netinsight #ipmedianetwork #unicast #openvideotransport #ipvideotransport #TrustBoundary

What is D2X? Introduced NAB 2024 this week Las Vegas. https://lnkd.in/eKMeePJa D2X standards recognize the essential role software plays in defining the Network, disaggregated RAN, UE, and service applications (APPs). Figure 6-1 shows the D2X service reception model, which facilitates market driven APP development and innovation using D2X standards. The horizontal dashed line shows the division of model between what is defined in the D2X standard and what is defined in the market. Figure 6-1 is shown from receiver UE perspective. 1)     The D2X Receiver / UE 2)     UE RF and Baseband Signal Processing Hardware (SDR) D2X (L1-L2) 3)     D2X (DLP) Interface Between HW (SDR) /Software on UE 4)     UE Software (L2-L7) processing for a Service Category (APP_ID) 5)     DST Specific Signaling and D2X Header Extension Signaling for (APP_ID) The L1/L2 layers shown are processed by Hardware/ SDR (2) on UE to acquire D2X signal and demodulate, FEC decode, time de-interleave, etc. and pass DLP L2 streams over DLP Interface (3) from hardware/SDR to software (4) on UE. The APP_ID for a specific Service Category uses extended (5) DST and D2X Header Extension for specific L2 signaling to support APP functionality. Example (10) Use Cases mapped to Service Categories and APPs Developed: ·        Emergency Alerts ·        Entertainment ·        Education ·        Mobile Television ·        Radio, Podcasts ·        File Delivery, Firmware Updates ·        Automotive ·        Smart City ·        5G Convergence ·        5G Convergence First Responders Each use case envisioned in market and developed is virtually mapped to a Service Category and can have a maximum 256 APPs developed and registered D2X network (APP_ID). These use cases are for D2X Multicast Broadcast that may be combined with 5G NR for QoS. The last service category 5G Convergence First Responders is seen as synergistic. Since, D2X and 5G NR (MBS) standards are diverse and optimized with different strengths and topologies. They can be used together synergistically for innovative use of the spectrum in times of emergency. The 5G convergence first responder use case is excellent for 5G NR (MBS) based on unicast framework with low latency and a single cell topology (strength) for first responders group communications. When complemented by D2X with a larger service area topology (strength). That multicast common data video in wider service area for first responders either at or in route to emergency scene. This D2X and 5G NR convergence is synergistic and can help save lives.  Note: for private APP development by government agencies, public safety service, homeland security, etc. These services are usually encrypted in addition virtual sub-frame carrying private service category is not discoverable by public.
