MediaTek MT8127 SoC to Bring H.265 Video Support to Mid-Range Android Tablets

MediaTek has just announced MT8127, a quad core ARM Cortex A7 processor @ 1.5 GHz with Mali-450MP GPU, that provides hardware support for HEVC (H.265) video playback, and targets “super-mid” range Android tablets. HEVC/H.265 video codec will allow to half the required bandwidth and/or storage for a given quality compared to H.264, or to greatly improve quality at the same bitrate. The latest Mediatek processor will also support 1080p video playback and recording, and up to 13MP cameras, as well as  1920×1200 LCD screen display. As with other Mediatek SoCs,  a Bluetooth 4.0, Wi-Fi, FM receiver and GPS combo-chip can be coupled with MTK8127. The company also claims Miracast and NFC support. The first tablets to integrate this solution will be ALCATEL ONETOUCH PIXI 7 and Cube U25GT, as well as ALCATEL ONETOUCH PIXI 8, which will be launched later this year.

New ARM Set-Top Box SoCs – Sigma Designs SMP8734 / SMP8756, STMicro STiH312 / StiH412, and Entropic EN7310 (Videos)

Broadcom and STMicro has the two companies that dominate the set-top box SoC market with respectively 44.7% and 34% market share by revenue in 2012, followed by Ali, a distant third at 6.9%. Other companies include Entropic, who has acquired Trident Systems, (4.4%) and Sigma Designs (1.4%) which has suffered in recent years. MIPS was the predominant architecture in the STB SoC market, but with the advent of Android, most companies have announced ARM based STB SoC for better compatibility with Android apps. TV Connect 2014, an event gathering stokeholder involved in Connected TV such as STB manufacturers, content providers, and SoC vendors, took place on March 18-20 in London, and Charbax,, interviewed three companies who promoted their latest ARM based STB SoCs: Sigma Designs with their SMP5734 & SMP8756/58 SoCs featuring single or dual cores Cortex A9 and a Mali-400 GPU STMicro with their STiH312 Cannes and STiH412 Monaco […]

BrightSign 4K Digital Signage Player Delivers 4K 10-bit HEVC Video Playback at 60 fps via HDMI 2.0

When you buy a media player advertized as supporting 4K (aka 2160p, 4K2K, or UHD), you have to read the fine print to find out what you really get. First on the market were media players capable of decoding 4K videos put outputting to 1080p60 maximum such as Mele M9, then we’ve been shown some media players such as Geniatech ATV1800, decoding 4K video using 2160p resolution (3840×2160) as expected, but with a framerate limited to 24 fps or 30 fps due to limitation of HDMI 1.4. However, if you want to experience 4K video with the maximum framerate (60 fps) or “True 4K”, you’ll need a player and a TV support HDMI 2.0 standard. There are not many players currently supporting 4K @ 60fps, but BrightSign 4K digital signage media player is one of them, and it also happens to support  HEVC/H.265 video codec. The company did not disclose […]

Play HEVC/H.265 Videos and Embed HEVC Streams into MP4 and TS Files with openHEVC and GPAC

I wrote an introduction to H.265 (aka HEVC) at the end of last year, including instructions showing how to encode videos to HEVC using the reference implementation. It worked but since it was not optimized for speed, it was extremely slow. Today I’ve stumbled across openHEVC, a open source compliant HEVC video decoder written in C, created as a fork of Libav. This is supposed to work pretty well as the implementation was used at Roland Garros Tennis tournament to playback an 720p50 HEVC stream transmitted over DVB-T2, IPTV, and MPEG DASH. Today I’ll mainly tried out the instructions provided on openHEVC github repo including: Build the source and playing a raw HEVC stream with hevc utility Build GPAC (open source multimedia framework), to get MP4Box, mp42ts, and MP4Client utilities. Import a raw HEVC stream into MP4 and TS containers, and play it back with GPAC tools. I’ve performed the […]

Xiph Daala Codec Aims to Better H.265/HEVC Video Codec

H.265 (aka HEVC) video codec will eventually supplement H.264 over the years as it offers better compression at the same bitrate, or better quality for the same compression ratio. There’s a already some experimental implementation that allows to (slowly) decode and encode H.265 on your PC, as well as some HEVC implementations optimized for ARM SoCs. At least two other codecs aim to compete against, and better, HEVC: Google VP9, and Daala codec (temporary codename) developed by, the open source community that brought Vorbis or Theora open source codecs to the world. The Xiph developers explains that next generation codecs such as VP9 and HEVC are incremental improvement of codec designs using DCT (Discrete Cosine Transform) that have been used for years, and they’ve decided to take a new approach with lapped transforms, a technique that is also used in audio codecs such as MP3 and Vorbis. Lots of […]

Ittiam HEVC Decoder To Provide H.265 Video Decoding for Existing ARM Cortex-A Devices

H.264 is now the favorite codec for many applications, and all ARM SoC providing multimedia capabilities support it. However, a new codec called H.265 (aka HEVC) is coming with twice the compression ratio with the same quality saving a lot of money for those who have to pay for the bandwidth. The transition between video codecs is normally a slow process, but as it happens you may wonder if you’ll be able to play H.265 videos on your existing ARM Cortex A9/A15 devices which do not support H.265 hardware video decoding. The answer appears to be “Yes You Can!”, as Ittiam Systems announced an HEVC decoder specifically designed for ARM Cortex A processors. More specifically their software decoder will support: ARMv7 Cores with NEON –  Cortex A8, Cortex A5, Cortex A9, Cortex A15, Cortex A7 and the multi core variants Qualcomm Snapdragon APQ8064/MPQ8064 , MSM8960 Ittiam HEVC decoder mainly targets devices such […]

H.265/HEVC (High Efficiency Video Coding) Status and How-To Encode Videos to H.265

Now H.264 is the main standard used for video compression, and most devices that can support video playback feature an SoCs capable of H.264 hardware video decoding. Since 2004, however, work has been done to improve H.264, and a new standard called High Efficiency Video Coding (HEVC), also referred to as H.265, will eventually replace H.264, even though this will take a few more years to really gain traction. HEVC will be able to double the data compression ratio compared to H.264 with the same quality, or improve the quality using the same bitrate, and it can support 8K UHD (Ultra High Definition) with a resolution of 7680×4320 (4320p). This new video codec is a big deal for those who pay for video bandwidth (80% of internet traffic according to Ericsson), and it should also be welcomed by consumers, as it will magically double their storage device capacity, and they may […]
