We were expecting Amlogic S905X4 TV boxes with products like Ugoos X4 or Mecool KM6 by the end of last month, but due to supply issues manufacturing has been delayed. However, if you’d need a device to get started with your own project as soon as possible, for example, to work on AV1 hardware decoding implementation, SEI Robotics has launched an Amlogic S905X4 developer kit for Android TV & RDK development under their DroidLogic brand. The devkit looks like a standard TV box, and the company also provides a choice of tuners with DVB-S2, DVB-T2/C, DVB-S2+DVB-T2/C Combo, ISTB-T, or ATSC-T. DroidLogic Amlogic S905X4 developer kit specifications: SoC – Amlogic S905X4 quad-core Cortex-A55 processor with Arm Mali-G31MP2 GPU (Amlogic S905X3 as option) System Memory – 2GB DDR4 Storage – 8GB eMMC flash Video Output – HDMI 2.1 up to 4Kp60 with CEC, HDR, and HDCP 2.2 support; CVBS (composite video) Video Decoding AV1 MP-10 L5.1 up to 4Kx2K @ 60fps VP9 […]
Intel launched various Core i3/i5/i7 Tiger Lake processors in early September, shortly followed by more Core i3/i5/i7 UP3 Tiger Lake Embedded SoCs, so I was a little confused when Congatec launched a Tiger Lake COM Express module with of choice of processors including the usual Core processor plus an unnamed Celeron Tiger Lake processor because none were listed in Intel Ark. But a few weeks have passed, and there are now three new Celeron and Pentium Tiger Lake processors in the list namely: Pentium Gold 7505, Celeron 6305, and Celeron 6305E with the later optimized for embedded & IoT applications with a wider temperature range from 0 to 100°C. All three processors come with a 15W TDP and are manufactured using Intel’s 10nm process. As we can see from the table below both Celeron 6305 and Celeron 6305E have the exact same key features. The main difference between the Celeron and Pentium part is that the latter supports Hyperthreading and […]
AOMedia AV1 royalty-free video codec delivers up to 50% better compression than H.264 and up to 20% better than VP9 for the same video content, so streaming companies like Netflix and YouTube enabled the codec a while ago. When I play a YouTube video in Chrome in Ubuntu 20.04 and check the stats for nerds info, it will usually show the video is played with “av01.0” codec which refers to AV1, but it’s played with software video decoding using libraries like Dav1d leveraging SIMD instructions. But ideally, you’d want hardware video decoding for lower power consumption for increased battery life, and potentially smoother videos. One good news is that Microsoft has recently announced support for AV1 GPU-accelerated hardware video decoding in Windows 10. The less good news is that support will be limited to recent and fairly powerful GPUs. So for instance, if you own mini PCs with older Intel SoC featuring integrated Intel HD/UHD graphics, AV1 hardware decoding won’t […]
We’ve heard about Amlogic S905X4 processor for 4K TV boxes with AV1 support for about year, and while we’ve written about upcoming S905X4 TV boxes such as SDMC DV8919, none of them have launched so far, as silicon design and/or software development have taken a bit longer than expected, and we’re now far from the Q4 2019 launch date shown on the roadmap. But we may not have to wait much longer, as I have been offered a review sample – which sadly, I may have to refuse due to local import regulations – for Mecool KM6 TV box based on Amlogic S905X4 quad-core Cortex-A55 processor coupled with up to 4GB RAM, 64GB storage, Gigabit Ethernet and WiFi 6 connectivity, and running Android 10 on Android TV (Android 10.0 ATV). The company will sell two models with Mecool KM6 Deluxe and Classic editions with the following specifications: SoC – Amlogic S905X4 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz […]
4K TV boxes capable of playing AV1 content are coming later this year. Many of the entry-level models will feature Amlogic S905X4 processor, but some higher-end set-top boxes will instead be equipped with Broadcom BCM7218X or Realtek RTD1319 processor with better video post-processing capabilities and often more extensive DRM support which can be important to operators. Dune HD AV1 4K TV box is coming later this year with Realtek RTD1319 media processor, and support for either Android 10 AOSP or Android TV for Android 10. Dune HD AV1 4K TV box specifications: SoC – Realtek RTD1319 quad-core Arm Cortex A55 processor with Mali-G31 GPU with OpenGL ES 3.2 API support System Memory – 2 GB RAM Storage – 16 GB flash (32 GB or more as an option) Video & Audio Output – HDMI 2.1 up to 4Kp60 with HDR support, 3.5mm AV port with composite video and analog stereo audio Video Playback AV1 up to 4Kp60 VP9 Profile 2 […]
AOMedia AV1 video codec has been in the works for several years, and has strong industry backing since it’s open-source, royalty-free and delivers compression similar or even superior to H.265. Some services like YouTube and Netflix have already started using AV1 on PCs where the CPU is powerful enough to handle software video decoding. But relying on software video decoding is not ideal on typical Arm-based devices, either because of battery life concerns (e.g. phones) or simply impossible because the processor won’t be able to cope. The latter is especially the case on TV boxes who are not usually fitted with Arm Cortex-A53 cores leaving hardware video decoding to a video processing unit (VPU). Since AV1 is still fairly new, most VPU doesn’t support the new video codec, and while we have seen several AV1 capable processors including Broadcom BCM7218x, Realtek RTD1311/RTD1319, and Amlogic S905X4. as well as at least one Android TV box for operators, I’m not aware of […]
We’ve previously covered several TV box & set-top box SoCs with support for the royalty-free AV1 video codec including Broadcom BCM7218X SoC, and Amlogic S805X2, S905X4, and S908X processors. But so far, apart from an AV1 demo on the RTD1311/RTD1319 development board (Pymparticle EVB?), and new about Technicolor Jade STB, I had not really seen AV1-capable TV boxes so far. SDMC DV8919 appears to be the first Amlogic S905X4 TV box on the market and one of the first running the recently released Android 10 on Android TV OS. SDMC DV8919 specifications: SoC – Amlogic S905X4 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G31MP2 supporting OpenGL ES3.2, Vulkan 1.1 and OpenCL 2.0 System Memory – 2GB DDR memory (options: 1GB or 4GB) Storage – 8GB eMMC flash (options: 16GB, 32GB, 64GB), MicroSD card slot Video Output – HDMI 2.1 up to 4K @ 60+Hz with CEC & HDCP2.2, AV output with composite video Input – HMDI […]
AOMedia AV1 open, royalty-free video codec has come a long way since it was first introduced in 2016, and we’ve recently seen AV1 hardware video decoding integrated into higher-end STB SoCs such as Broadcom BCM7218X or Realtek RTD1311/RTD1319 processors. But AV1 codec is also coming to lower-cost media processors as shown by Amlogic 2020 roadmap below. We should expect at least three new AV1 capable processors in 2020. Amlogic S905X4 Specifications: CPU – Quad-core Arm Cortex-A55 processor GPU Arm Mali-G31MP2 Video 4Kp75 H.265, VP9, AVS2 4Kp120 AV1 HDR support Smart Audio Voice Activity Detector (VAD) Asynchronous Sample Rate conversion (ASRC) Equalizer (EQ) Dynamic Range Compression (DRC) 2x DSP for audio front end (AFE) and wake word engine (WWE) Amlogic S905X4 looks like an update to Amlogic S905X3 with AV1 codec support, and maybe extra audio features. Amlogic S908X We’ve previously seen Rockchip RK3588 with Cortex-A76 / A55 cores, 8K video output and decoding support, as well as 4K encoding, is […]
