Nasa TV UHD on HOTBIRD: "Service not supported"

Hi everyone,

just a curiosity: until a couple of weeks ago this channel was broadcasting in 4K a looped playlist of 4k contents.

Then for a couple of days it showed a TESTCARD image.

Now it's showing nothing and "service not supported" pops up (obviously I tried already to retune it)

This is the channel:

Can anyone see it, is it a firmware problem or it's the channel itself?

Usually I analyze this using a satellite card on a pc but I don't have that now.

 

P.S.

I own an OLED CX65  but I don't think is a TV problem. It looks like they are testing codecs or other stuff.

I am just curious if at the moment it is visible or what.

Hi I also receive the same info: "Service not supported". Don't know what they did to the hardware but there was some changes. Here is link to reddit topic, Would be good to ask what is the reason that we don't have image: 

This is strange because on LG I get this message as mentioned but on Samsung TV I have only sound. At least I'm not the only one with the same issue :D Found some info that it's now broadcasting at 60 fps and that might be the issue. Previously it was on 30 fps.

NASA UHD is back on air again just checked and boom it works - hurray ! :) Hope it will stay longer this time 

Last two updates from reddit topic this month:

 

UPDATE: 20 Mar 2022, we've installed a Harmonic ProView 7100 at our satellite dish location in Eugene, OR. This receiver is performing far better than the previous "GT Media" IRD that we had began this project with, and of course resolves the 'blips' we had every ~26 minutes using the GT Media TSoHTTP websocket... We thank Harmonic folk for sending us this unit, gratis, and appreciate their support of our project!

For stats nerds, what the ProView thinks about the NASA Galaxy 13 downlink parameters: 

RF Status: Locked
C/N (dBc): 17.2
Eb/No (dB): 15.79
Link Margin (dB): 10.29
BER: 0E-10
Modulation Standard: DVB-S 
Carrier Frequency (GHz): 3.920124
L-Band Frequency (GHz): 1.230124
Frequency Offset (kHz): 124
Spectral Inversion: Inverted
Modulation & FEC: QPSK 3/4
Symbol Rate (Msym/s): 28.070316

UPDATE: 3 Mar 2022, NASA has reverted to standard 8-bit luma+chroma on the UHD satellite feed, after reports of some compatibility issues with 10-bit formats. We are still converting to a 10-bit format for the 30 fps stream to allow for best-case decoder performance and visual quality. Since most folks are using software players on the web, we enjoy broad main10 profile support, in contrast to 'hardware' decoders which often do not. NASA TV folks advised us to keep an eye out for updated and new segments being aired soon. Hopefully more folks who enjoy this stream can send emails to NASA TV folks and thank them for their work on creating and managing good content for the UHD channel. We've also added a handy, 1080/HD scaled flavor of the 30 fps stream, with a handy HTML5 player & Chromecast support. Scroll down for that URL.

      EDID version of OLED55C6V or supported resolution detection
      By dolbnya
      I have a mediaplayer connected to my TV OLED55C6V through HDMI. For every video playback the player tries to select an output HDMI signal format automatically depending on both video framerate/resolution and framerate/resolution supported by the connected TV to show the video as close to original as possible with the TV without any scaling. And here I have a problem: the maximum resolution the player selects is 1080p despite of the videofile has resolution 4k and the TV supports playback of the input signal up to 4K60p. I can change the output signal resolution on the player manually after blayback starting and it works, but it's not convenient. As far as I know the only way of getting information about videosignal format supported by TV for the player is EDID on HDMI channel. So is it possible to fix the issue? Maybe some hidden setting in TV could change the version of EDID?

      New LG CLOi ServeBot Delivers Smooth Performance for Reliable Customer Service
      By News Reporter
      With Six Wheels and Independent Suspension, LG’s Latest Autonomous Serving Robot
      Offers Enhanced Service Delivery in Food Retail Environments

      SEOUL, July 19, 2023 — LG Electronics (LG) has unveiled its newest LG CLOi ServeBot (model LDLTR30), a smart service robot convenient for places where service is needed, including restaurants. Boasting a quick and stable autonomous driving system that can handle various types of flooring, and an upgraded design with enhanced features, LG CLOi ServeBot ensures reliable service delivery. The new model also has a guide function for helping customers to find their way around, freeing up staff to spend more time on management and administrative duties.
      First launched in early 2020, LG CLOi ServeBot is designed to be deployed in public spaces such as restaurants, hospitals and office buildings to assist humans without human-to-human interaction, and is optimized for in-person customer service. The latest version offers enhanced driving performance with 6 wheels and independent suspension, allowing for stable operation on different kinds of flooring, including carpet and braille blocks. It also has a 3D camera and a light detection and ranging (LiDAR) sensor. This enables the CLOi ServeBot to securely transport beverages and meals, including soups and noodles, even when travelling over surfaces with a slope of up to 5 millimeters (0.2 inches). Additionally, this advanced technology lets the CLOi ServeBot navigate obstacles smoothly, ensuring that none of its valuable “cargo” is upset.
      The new LG CLOi ServeBot also delivers increased storage capacity and flexibility. Its 4 easy-to-access shelves (21 x 17 inches) – including one that can be used as main drawer – can collectively manage a load of up to 40 kilograms (88 pounds). The upgraded LG CLOi ServeBot offers further convenience with its upper pockets and cup holders, and features an additional bottom drawer that can be used for storing items such as napkins and utensils. For extra versatility, the LG CLOi ServeBot’s shelves are detachable and can be adjusted up or down within a range of 2.8 inches.
      LG’s newest CLOi ServeBot provides smarter service thanks to its large 10.1-inch display and built-in content management system. Operators can adapt the autonomous robot for a specific use scenario by choosing an appropriate facial expression and by displaying videos, images or text. As such, LG CLOi ServeBot can communicate relevant information to customers, such as menu recommendations or in-store promotions, and also advertise services from partner companies. Additionally, LG CLOi ServeBot can be used for entertainment purposes, such as displaying customized content for special events and celebrations. What’s more, LG’s new service robots communicate with each other to coordinate their movements; facilitating smooth, efficient operation in food retail environments.
      “LG CLOi ServeBot is a reliable partner capable of efficiently carrying out various service delivery tasks, from serving and guiding customers to providing engaging entertainment and useful information,” said Roh Kyu-chan, vice president and head of the robot business division of LG Electronics Business Solutions Company. “Leveraging LG’s autonomous robotic technology, we will continue to consistently deliver new and exciting experiences that bring greater value to our customers.”
      LG’s new CLOi ServeBot is currently available in the United States and Japan, with plans for a global rollout in the future.

      LG CEO Inspects Service Site, Emphasizing Uncompromising Customer Experience
      By News Reporter
      According to LG, nothing is more important than providing outstanding customer experiences through its advanced products and services. Driven by its core value of always delivering an ‘Uncompromising Customer Experience,’ LG prioritizes the creation of first-class customer experiences above all else.

      The company strives to deliver exceptional quality at every stage of the product life cycle, from initial product planning and providing after-sales service to the release of a new model.
      With this in mind, LG CEO William Cho recently took the time to inspect a service site before Korea’s peak summer season hits.

      On June 16, the CEO visited the company’s service center in Hongdae – a vibrant, youthful district of Seoul – to look into how preparations for its after-sales service peak season, from June to August, were going.
      He first examined the status of securing special support personnel in areas where service requests are concentrated, building a system that enables service managers in neighboring areas to provide immediate support so that customers don’t have to wait long at a time when the heat is almost unbearable.
      The CEO also reviewed the manuals used in the event of natural disasters, such as a heat wave or torrential rain. And as more rain is forecasted this summer, the system has been reorganized to provide immediate recovery support during a disastrous flooding event.
      CEO Cho then went on home appliance repair calls related to LG’s refrigerators or ACs, which allowed him to listen to stories and feedback from customers in their own homes.
      “My heart goes out to customers worried about the recent hot and humid weather,” said CEO Cho. “We will continue to do everything we can to respond to and address customer inconveniences on time without delays.”
      The company has made continuous efforts to make summer as cool and enjoyable as possible. For instance, LG has been conducting AC pre-inspections since March, which involves a service engineer visiting the customer’s home to check the appliance’s performance free of charge. In fact, the company has already made three times more pre-inspections of its ACs than last year.
      CEO Cho has also talked directly with service managers to better understand the factors that increase their sense of accomplishment and the difficulties they have felt in the field, and to brainstorm new ideas for providing faster, more efficient services. “Symbolic of LG’s customer service, service managers play the most important role in bringing a smile to customers as the real faces of our company,” mentioned Mr. Cho, who continued by reiterating the company’s commitment to discovering various ways to make life good for customers.

      The company has long prioritized providing quality after-sales services. Since 2002, LG held an internal event called the ‘Service Olympics,’ which challenged service managers to put their service capabilities to the test and share their know-how with other service workers so that every possible appliance issue can be handled swiftly going forward.

      In March, CEO Cho visited Hi-Teleservice, an LG subsidiary specializing in customer service, to meet customer counseling consultants. Recognizing that a better working environment for customer service pros can lead to excellent customer experiences, he encouraged the introduction of a “balanced work system” that allows them to work from home three weeks per month, as well as activities promoting effective communication in the workplace.
      The company plans to continue conducting on-site service inspections by executives to best reflect customer feedback into its service policies. “True customer experience innovation begins with listening to the customer and is only complete when that customer is left smiling with satisfaction,” said CEO Cho.
