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

🚨 Features of "Video Quality Monitor", episode 4 🚨 In previous posts, I detailed the metrics, the many different video and audio inputs and the reporting functions in "Video Quality Monitor" (VQM). Today, let's see the special features in VQM. VQM includes several original features: - if you plug an infrared receiver/emitter, you can capture infrared codes from a remote control and re-play them in a script. VQM can also send network commands to control a STB. Useful for STB test and validation. - if you plug a GPS receiver to your PC (a laptop for example), you can create geographic maps showing the quality of video and audio with respect to location. Useful for 3G/4G/5G deployments. - if you want to measure lipsync, VQM can generate an audio/video test signal that you can use as input of your processing chain (encoding, transport, decoding...) in order to check the synchronization between audio and video - VQM can extract the PTS (Presentation Time Stamp) and DTS (Decoding Time Stamp) of a video. Useful to detect lost frames. - VQM can detect pre-defined content (logos, error messages, etc) - VQM can generate particular videos to measure contrast modulation and it can measure colorfulness. Useful to benchmark display devices. - VQM can measure video camera noise, with or without motion compensation. Useful to benchmark video cameras. - VQM can save video samples of problems (low quality, too much blur, etc.). And since all inputs are buffered, VQM can save samples showing how was the video BEFORE the problem happens (so you see the video before and you see the problem appearing). - VQM can save the packets of an MPEG-2 Transport Stream. - VQM can detect the dead pixels in a video - In VQM, you can create scripts to automate processing steps - VQM can be controlled by command line and more... Would you like to test some of these special features of VQM? Evaluation is free!

INSIGHT: State of UHD Broadcast in Europe With the 4K Summit taking place from November 11-14 in Seville, Spain, where broadcasters from France, Spain, and Italy will present their progress on UHD deployments, now is the perfect time to review the state of UHD broadcasting in Europe. In Spain, Televisión Española (TVE) was the first terrestrial broadcaster to offer Ultra High Definition (UHD) content. In February 2024, TVE launched a nationwide free-to-air UHD channel via Digital Terrestrial Television (DTT), initially simulcasting its main channel, La 1, in UHD/HDR. Notably, the SD switch-off has not yet fully occurred in Spain, and once SD broadcasting ceases, more spectrum will become available for additional UHD channels. In France, France Télévisions (FTV) was the first to offer UHD content on terrestrial television. During the Paris Olympic Games in August 2024, FTV launched a nationwide free-to-air UHD channel via DTT, initially simulcasting its main channel, France 2, in native 4K resolution for Olympic coverage, while France 3 content was upconverted from HD to 4K.France is looking at deploying UHD only channels by 2028, this would only be possible if it is mandatory regulation. The solution deployed in Spain and Italy are DVB compliant and is a brute force simulcast of UHD in addition to the already deployed HD channels, needless to say those solutions are not efficient in terms of spectrum usage. Germany, on the other hand, has so far limited DTT transmission to 1080p SDR and has shown little interest in advancing beyond that resolution. However, German broadcasters may deliver UHD services through other distribution networks, such as pay TV (DTH, Cable, IPTV). Italy lags in UHD adoption for two main reasons. First, a significant number of TVs in Italy still cannot decode HEVC signals, and the current priority is to migrate all broadcast channels to 1080p SDR in HEVC. Second, there no spectrum available for UHD, making solutions like MPEG-5 LCEVC appealing due to its bandwidth efficiency. In this setup, the HD channel would serve as the base layer (in SDR), with the LCEVC enhancement layer providing a UHD HDR signal that only newer TVs could process. Notably, such a backward-compatible scheme has yet to be deployed, meaning Italy would be the first to do so. In the UK, there are no plans to upgrade the DTT network for UHD, with an IP transition planned instead for all broadcast channels. The BBC is expected to lead this transition, although the timeline remains undefined. Nordic countries have established a UHD specification,  but no deployments have occurred to date. If you consider attending  the 4K summit, this is the best place to network with professionals on UHD topic: https://lnkd.in/gunDCrPy Jacques Donat-Bouillud Stephan Heimbecher Mickaël Raulet Benjamin Schwarz Ian Nock Simone Ferrara Jan Outters Jason Power

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.

This should be the way to go I believe even now in Africa in markets like Kenya, Uganda, Tanzania and Rwanda this would be a great way to expand the media players space and to have new entrants accommodated while largely reducing the cost of operations for small scale and Community based Broadcasters. This would create more variety and yes new offering into the market.

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

Another reason #euro2024 should be a fun watch – 5G will be involved! Broadcaster RTL Deutschland and Deutsche Telekom are working together to use 5G services via a private 5G network to deliver “data-intensive applications” with the network running in the 3.7GHz to 3.8GHz range and offering up to 100MHz of bandwidth to the broadcaster. Great to see innovation being driven by events in the market to actually test use cases and push barriers rather than there merely being a lot of talk about how great private networks could be. #connectivity #networks #privatenetworks #private5g #investment #innovation #mnos #Germany #2g #3g #4g #5g #business #enterprise #growth #mobile #mobilenetworks #telecoms #telecommunications #technology #stadiums #sport #football https://lnkd.in/e_QH3wPi

#NAB2024 Report on Edge CDN We are all familiar with public CDNs and their ability, or lack thereof, to handle the peak traffic of major live events. Conversations with insiders at the show reveal that events exclusively available through OTT providers, not broadcasted, are putting significant strain on public CDN infrastructure. Now, imagine the event isn't a US football game but the FIFA World Cup final, where billions of people will flood all public CDNs, spanning a wide range of ISP network connections to the internet. The solution to this is to bring additional capacity through mechanisms like Open Caching. However, Open Caching, initially championed by Disney, receives limited support from the content provider community and even vendors, aside from Qwilt, who fully support the technology. The industry is now seeking alternative methods to build Edge caching capacity, with the ultimate goal being an Edge Cloud infrastructure available at every major ISP, ready to be activated on demand to handle peak live video traffic. However, this is not expected to happen for some time, so in the meantime, we must rely on more practical solutions. I've written an article on the subject of CDN diversity that can provide a better understanding of the various options available: https://lnkd.in/dEgtMW9d One such option is to utilize the caching infrastructure already deployed at ISPs for their on-net traffic (ABR TV on private networks, also known as IPTV 2.0), and expand this capacity to handle internet video traffic. A few companies have already taken this approach, such as Broadpeak and Synamedia. Other companies, like Velocix, are exploring a hybrid model where steady traffic could be served from on-net caches, while bursty traffic from live events would rely on public CDNs. Companies like Netskrt, which just closed a round A of $7.5M, are considering deploying edge caches inside ISPs that lack sufficient connectivity. I'm certain the CDN Alliance is closely monitoring this evolution of CDNs moving inside ISP networks with great interest, so stay tuned for their next move. Once again, delivering IP at scale with broadcast-quality of experience (QoE) is going to be the challenge of our industry in the next five years, especially when countries like the UK will migrate major broadcasters like the BBC over 100! “We are not in Kansas anymore.” Jason Thibeault Mark de Jong Xavier De Clercq Gwendal Simon Steve Miller-Jones Ian Nock Colin Dixon
