Atlona has launched the Avance series of HDBaseT expansion kits, thereby expanding its lineup of HDMI expansion solutions. The new HDBaseT transmitter and receiver kits are based on the core functions of the company's UHD-EX series and have integrator-friendly additional functions. They provide a cost-effective and reliable solution to extend 4K/UHD AV signals to HDMI The distance of the cable is outside the limit.
Four Avance kits transmit 4K/UHD 60Hz 4:2:0 video up to 130 feet (40 meters) or 1080p 60Hz video up to 230 feet (70 meters) over Cat-6A/7 twisted pair cables, while the second one Transmission 4K 60Hz 4:2:0 video can be played at a distance of up to 330 feet (100 meters).
The Avance series lineup includes:
All Avance series extender kits have features that enhance reliability and simplify deployment by integrators and installers. EDID filtering prevents expansion of unsupported resolutions to improve the integrity of video transmission, while clock extension improves interoperability with traditional and low-quality HDMI video sources. The integrated HDBaseT link test verifies cabling, termination and link quality during installation.
A new feature of the Avance series is a two-way remote power supply, which can be used on AVA-EX70C-BP-KIT and AVA-EX100CE-BP-KIT. By choosing whether the transmitter powers the receiver or vice versa, it improves installation flexibility. Depending on the available outlets, this can allow the power source to be located near the signal source or display.
"The Avance series continues our tradition of providing multiple product choices, allowing customers to choose the right model according to their project requirements and budget," said David Shamir, Director of Product Management at Atlona. "The new EDID filtering, clock expansion, and link test functions also reflect our commitment to simplify installation and ensure maximum reliability, thereby making the job of system integrators easier."
The Avance series suites provide flexible installation options for commercial applications ranging from conference rooms and classrooms to long-distance video distribution.
Three of the Avance series kits (AT-AVA-EX70-2PS-KIT, AVA-EX70C-BP-KIT and AVA-EX100CE-BP-KIT) can be used immediately through Atlona’s authorized channel partner network. The remaining kits will be available in late August.

Roku is a very popular name in the home streaming world. The company provides a large number of streaming media joysticks and smart TVs, so if Roku doesn't work properly, what should you do? Although we cannot teach you how to build your favorite apps for this platform, we can provide you with many troubleshooting tips. The following are the most common Roku problems and their solutions.
Ideally, your Roku should never really face these problems. However, it is important to master some skills. If none of these methods seem to work, then it may be time to check our
Used for new streaming media devices.
The good news is that the most common Roku problems can be solved with a simple system update, reboot or reset. Obviously, updating or restarting is faster than resetting, but we will guide you through all three processes.
Most Roku updates are done automatically in the background, but no one is perfect. Sometimes, you may find that you have to roll up your sleeves and update yourself. What does this do:
If you encounter problems, there are actually two ways to restart the Roku streaming device. If your remote is working and can be fully controlled, the first method is best, and if the device seems to be frozen, the second method is better. There are two methods:
Factory reset is the most extreme way to fix most Roku issues. As the name suggests, it will restore your streaming media device to its default settings. You must re-download and re-login all applications, but this should help fix common errors. What does this do:
You can also use Roku's physical reset button to skip the menu steps. Some devices have large buttons that you can press with your fingers, although you need a paperclip or something similar to press the pinhole reset button on the Roku Ultra.
Roku streaming devices are generally reliable, but no one is perfect. Sometimes, you will find that the hardware itself is the source of the problem. There are not many things that can go wrong, but please pay attention to the following points:
If you place the Roku on top of other devices or in a narrow space, it may overheat. This shouldn't be very common, but if the Roku overheats, you will see a warning on the screen. Some Roku devices also have LED lights that will light up red when overheated.
When you see a warning or LED indicator on the screen, immediately turn off Roku and unplug the power plug. Wait ten minutes or more, then reconnect the device and turn on the power again. If the problem persists, turn off Roku and unplug it. If you cannot find a way to cool the device, you may have to contact Roku, as this may indicate a major hardware problem.
You may also encounter a problem where the Roku's power supply is insufficient, displayed as a red LED or a warning on the screen. If you have plugged a USB-powered Roku device into the TV in a closed loop, it may be the cause of the problem. Some TVs have USB sockets that have less power than other TVs, while others are not intended to provide power at all.
The easiest way to solve this Roku problem is to plug the USB into the power adapter that came in the original box. Roku designed the adapter to provide the correct power level, so trust the hardware! If you still have problems, try moving the power adapter to a new outlet or power distribution panel.
Most Roku products come with simple IR remotes, but Streaming Stick Plus and Ultra complicate Wi-Fi remotes. Of course, they can enable you to point out any results, but you may experience connection problems. Most of these problems should be easy to resolve during installation, but if not, you can try the following:
Unfortunately, the infrared remote control still needs a direct line of sight to your streaming media device. This means that you have to move all obstacles between yourself and the streaming device. Make sure to check the line of sight from wherever you want to sit in front of the TV.
You can also replace the battery in the IR remote control to strengthen the connection. The infrared emitter works like a flashlight, only as good as its beam intensity. Replacing a new set of batteries should help solve this type of Roku problem.
Roku's Wi-Fi remote is slightly more complicated, but it is also significantly more powerful. You can try the battery tricks mentioned above, but it can also help restart or re-pair remote devices and streaming devices. Please try the following steps:
This should restart the two components, if you must re-pair the two components, you can do the following:
If you are not sure which remote to use, remove the battery cover. If you have a Wi-Fi remote control, you will see a small pairing button, but the IR remote control will not provide that button.
Your Roku device needs a stable internet connection to reliably pump content to the TV. One of the most common causes of Roku problems is if you don't have a strong enough connection. On the bright side, this is usually not because of a problem with your streaming device.
You can check the Roku connection status from the "Settings" menu. Just go to the "Network" section and look for the "Signal Strength" indicator. You should see "excellent", "good", "fair" or "bad" indicators. If your connection is normal or poor, you may want to try to improve the connection.
If your Roku device has an Ethernet port, try to connect to the Internet this way to test whether the problem is due to Wi-Fi. This may mean that you have to reset the router, or you may want to relocate the Roku. It is not always possible, especially if you have a streaming joystick, but you can also try to relocate the TV. The error code 009 on Roku means that it is connected to the router without the Internet. If this happens, restart Roku.
Audio and video issues on Roku can come from several different locations. There may be a problem with your application or software settings, but if the connection is incorrect, it may also be a hardware problem.
Before trying these more complex solutions, try restarting Roku first. Unplug the power plug, wait a few seconds, and then turn on the power again. This sounds like a stupid answer, but it usually works miracles.
Any question? Here are some possible solutions:
If you have a Roku, please check your HDMI input on both ends. All your cables should be firmly connected to the TV and streaming media device. You may also need to check if you are connected to the correct audio input. Finally, make sure to turn off the mute function, and then try to adjust the TV volume.
You can use the "Settings" menu to adjust the audio input. Press the "Home" button on the remote control and go to "Settings", where you will find the "Audio" option. If you connect via HDMI, please adjust the setting to "Stereo" and then change HDMI to "PCM-Stereo".
You may notice that your audio and video playback are out of sync. In this case, you may have to mess up the video refresh settings. Just follow the steps below:
Roku's companion app is an essential add-on for Android and iOS users, but it may cause some common problems. You can use the app as a remote control, which is the easiest way to add content to a streaming device. However, you must ensure that the connection settings are correctly obtained. Like most problems, the root cause may be your Wi-Fi connection, so here are some solutions:
Modern Wi-Fi routers usually come with two different networks-2.4 GHz option and 5 GHz option. You should make sure that both your phone and streaming media device are connected to the same network, just in case. The two networks should be able to communicate with each other, but sometimes you have to be extra careful.
Hope we can help you find solutions to the most common Roku problems. If none of the above techniques work, it may be time to replace your
. Fortunately, we have many favorites to recommend, please try them!

Flipkart has launched an Android-based smart TV stick-Motorola 4K Android TV stick. Although the device offers 4K output, its price is competitive at Rs 3,999. You will get the third-generation Amazon Fire TV Stick (
) Is sold at the same price, while Mi Box 4K (
) The price is Rs 3,499. Motorola 4K Android TV Stick can run directly on Android 9 and supports HDR10. It has 16GB of built-in storage space and 2GB of RAM. It also supports dual-band Wi-Fi. The Motorola 4K Android TV streaming stick will be available from the third week of March. This is a comparison of the specifications and features of Motorola 4K Android TV Stick with Fire TV Stick and Xiaomi Mi Box 4K.
The price of the Motorola 4K Android TV Stick is Rs 3,999. The price of Motorola 4K Android TV Stick is the same as Amazon Fire TV Stick (3rd generation). The Amazon Fire TV Stick has FHD resolution, but this will be covered more in the next section. in order to get
, Then you have to pay 6,000 rupees. On the other hand, the price of Mi Box 4K is Rs 3499.
The Motorola 4K Android TV Stick is equipped with 16GB of built-in storage, 2GB of RAM and a Cortex A53 quad-core processor with a clock frequency of 2GHz. On the other hand, the third-generation Fire TV Stick has 8GB of built-in storage and is powered by a quad-core 1.7GHz CPU. Although RAM is not officially mentioned, it is speculated that it has 1.5GB of RAM. On the other hand, Mi Box 4K is driven by a Cortex-A53 quad-core 64-bit clock with a clock frequency of 2.0Ghz, and is equipped with 2GB RAM and 8GB storage space.
All three streaming media devices support dual-band Wi-Fi. The third-generation Fire TV TV stick has Bluetooth 5.0, while Mi Box 4K has Bluetooth 4.2.
Both Mi Box 4K and Motorola 4K Android TV Stick can run on Android, allowing you to access the Google Play Store. On the other hand, Fire TV Stick has its own app store, which gives you access to all popular streaming services. All three sticks can use popular OTT platforms, including
,
, Zee5, YouTube, voting, etc. For popular OTT platforms, it is clear that they are equivalent. However, Fire TV Stick supports
, Is not available on the other two devices. The category of apps in the Google Play Store may be larger, but insist on using apps that are used with such devices (including Plex, Internet browsers, etc.), all three are the same.
The Motorola 4K Android TV Stick and Mi Box 4K both come with a voice-enabled remote control, as does the Fire TV Stick. Motorola Stick and Mi Box 4K support Google Assistant, while Fire TV Stick supports Alexa. Both of these assistants allow you to control your own smart appliances from the convenience of each device.
All three devices have simple remote controls. The remote control of the Motorola 4K Android TV Stick looks a lot like the remote control on Nokia Media Streaming. It also has hot keys to start Netflix, Zee5, YouTube and Prime Video. The Mi Box 4K has the same Mi TV remote control as the Netflix and Prime video hotkeys. There is no Fire TV Stick with OTT hotkey on the remote control. All three remote controls have functional dimensions.
The appearance of Motorola’s 4K Android TV Stick is similar to that of Nokia’s Media Streamer (
), but the corners are sharper. The HDMI connector is located at the end of the small extension, so the streaming device will not block other HDMI ports on the TV. There is an HDMI cable in the Mi Box 4K box. Although the length is not very long, it can ensure that the device will not block the HDMI port of the TV. The Fire TV Stick box also contains an HDMI extender to ensure that the HDMI port of the TV will not be blocked. If the extender is not used, the joystick itself will be so thick that it cannot be connected to the adjacent HDMI port.
Motorola 4K Android TV Stick and Mi Box 4K support
Built-in, and Fire TV Stick supports screen mirroring.
Motorola 4K Android TV Stick and Mi Box 4K both support 4K, HDR 10 and HLG resolutions. They do not support Dolby Vision. For audio, both support Dolby Audio, but not Dolby Atmos.
The resolution of the Fire TV Stick is 1080p and supports HDR, HDR10+ and HLG Full HD. Again, there is no support from Dolby Vision. However, it does support Dolby Atmos, which is missing from the other two.
Motorola 4K Android TV Stick and Mi Box 4K seem to be homogeneous in terms of functionality. Of course, Motorola streaming media sticks have more storage space, but Mi Box 4K has a USB port that allows you to play content on external devices. Both support 4K resolution and support HDR. The Fire TV Stick is the only device that supports 1080p. However, it does support Dolby Atmos, which other devices lack.

The HDMI 2.1 specification introduced compression through VESA’s Display Stream Compression, but what does this mean for integrators looking for the best cable?
Somewhere in the process, "compression" means
Technology has become a bad word. why? Over the years, the promotion of HDMI connections to an uncompressed state may have something to do with it. This part is related to quality, but mainly related to interoperability. But the situation is changing, and integrators should regard compression as their friend, which will increase functionality while reducing cable stress due to the ever-increasing demand for bandwidth.
Remember, the only truly uncompressed video we see comes from the graphics processing unit (GPU), such as video from a game console. All other content is delivered in compressed form. a lot of. Broadcasting, streaming media, optical discs, they are all highly compressed as sources, and then uncompressed to be transmitted through the HDMI system. I think we can all prove the extraordinary performance potential of these resources, so compression itself is not an issue for quality. Well, if it is not done well, but we should avoid doing it badly anyway!
The key is interoperability. The range of video compression methods and processing capabilities is very wide, and the devices must all be on the same page. In addition, many methods take some time to perform compression, which means waiting time. This is also a problem. Since its inception, HDMI transmission has been absolutely decompressed, so the device does not have to deal with this additional complexity, and always remains latency-free. But with the development of video, bandwidth becomes indispensable for every four times the resolution is increased.
This
This specification introduces compression through VESA's Display Stream Compression (DSC). This is an ultra-fast line code "sandwich" compression codec with a very light variable ratio ranging from 1.3:1 to approximately 3.5:1. I calculated the numbers and found that the delay is lower in two-digit microseconds at 4K/60. This is completely imperceptible and has no effect on image quality. By the way, this is the same codec included in the DisplayPort 1.4 and 2.0 specifications, and can also be used with HDBaseT 2.0 to achieve 18Gbps support.
Two things can be achieved by using DSC in HDMI transmission:
DSC is optional and automatic if supported, but only provided when needed-if the system can send uncompressed files in a given format, it can. The caveat about interoperability is that all devices from the source to the sink need to support DSC to work properly.
The only exception is any bit-accurate throughput without decoding HDMI signals; for example, a fiber extender with direct bit mapping doesn't care what is inside—it has nothing to do with DSC, HDCP, etc. The raw data rate is critical. However, for AVRs, etc., the situation is quite different, because they do decode HDMI signals. However, if such a repeater device does not support DSC, the source will not send it first (EDID will do).
DSC has been standardized for the HDMI specification, which is the first step to achieve interoperability. But for this, integrators need information to make informed decisions. This is where the manufacturers come in and disclose the importance of functionality through appropriate labels. In other words, what the product can and cannot do.
The HDMI Forum has proposed a method to disclose the DSC function-list each supported video format and append "A" (only for uncompressed), "B" (only for compressed) or "AB" ( Indicates that both can be supported at the same time). It is proposed to use it in the manufacturer's specification sheet and marketing to support it in the indicated format, but it depends on whether and how the manufacturer discloses the format. I hope such a list can indicate the available data rate of the device, so this information is only for explanation, not absolute.
For example, a device with 40Gbps capability may declare 4K/120AB and 8K/60AB (despite 4:2:0), but can only support 8K/120B because there is not enough bandwidth for uncompressed 8K/120. Therefore, at 40Gbps, 8K/60 4:2:0 media will be sent in an uncompressed manner.
However, this may cause confusion-assuming the media is 8K/60 4:4:4, it needs to be compressed and sent. From 4:2:0 to 4:4:4 is enough to make it exceed 40Gbps, so some knowledge and explanation are needed. In another example, suppose the media is 4K/120, but there is something (device or cable/extender, etc.) between the source and the sink that limits the bandwidth, and the link training protocol limits the link speed to 24Gbps. As long as all devices support DSC (and 4K/120B), the source must send compressed 4K/120.
This is just my opinion, but I think the marking convention is not complete because it only focuses on resolution and refresh rate, and cannot distinguish between 4:2:0 and 4:4:4/RGB or bit depth. What I really want to see is the obvious difference. For example, a device with 40Gbps capability and DSC is declared as capable of supporting 8K/60AB 10-bit 4:2:0 (may be uncompressed) or 8K/60B 10-bit 4:4:4 (compressed only).
As always, the availability of information and education to interpret the information are the keys to the successful implementation of the HDMI system. I encourage discussion around this topic, and consider the standardization of using DSC in HDMI systems, industry-wide labeling conventions.
And please remember to pay attention to the new CEDIA/CTA-RP28 (previously known as CEB28) HDMI system design and verification recommended practices, which is an important free industry tool that does contain information about compression in HDMI transmission.
