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, armdevices.net, 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 SoC both featuring a dual core ARM Cortex-A9 with a Mali-400MP4 GPU
- Entropic with their EN7310 featuring ARM Cortex-A9 cores (1 to 4) and a Mali-400 GPU
Sigma Desigms SMP8756 was announced at CES 2014. It is part of the company’s new SMP8750 series SoC, supports 4K2K and HEVC, broadcast TS processing, secure media processing, multi-format Full-HD video decoding, VXP display processing and certification of CAS technologies (Verimatrix and Nagravision) are planned. Sigma previous secure media processors, which are still in used in new design today, were all based on MIPS, and this is their first ARM based SoC. SMP8734 is a least powerful version without support for 4K.
Android and Linux SDKs are both available. The Android SDK is based on Android 4.2 with support for OpenMAX, OpenGL ES 2.0, DVB software stacks, and hybrid STB API for support for tuners and demodulators. DTV middleware stacks and IPTV middleware ports, such as Netgem middleware for IPTV & VoD and OpenTV. Hardware reference platform are also available.
In the video below, we can see SMP8734 Vantage reference platform running Android, as well as SMP8756 showing 4K2K decoding and playback.
Products basedon SMP8734 should be available in Q4 2014, and SMP5756/SMP5758 in Q2 2015. There’s still no SMP8700 series page on Sigma Designs website.
ST Micro switch to ARM from SH-4 architecture back in 2011, and I’ve already wrote about StiH416 dual core cortex A9 SoC and its development resources last year. THe company has now announced two other ARM based SoC with StiH312 (Cannes) and STiH412 (Monaco) dual core processors which support Ultra HD, HEVC video decoding & encoding, video transcoding, concurrent conditional access and DRM, USB 3.0, PCI-e, SATA and Gigabit Ethernet, and more. The SoC interfaces allow for MoCA 2.0 (Multimedia over Coax Alliance), DOCSIS 3.0 (Data Over Cable Service Interface Specification), satellite, 802.11ac Wi-Fi, etc… Their processor runs Android, “Google TV”, as well as Cisco & Nagra solutions, and the Cable RDK.
Entropic EN7310 features one to four ARM Cortex A9 cores, a Mali-400 GPU, and is designed for satellite STBS with dual DVB-S/S2 cable reception capability, MoCa 2.0 support, HEVC decode up to 1080p60, and DRM. They also have EN730x family for cable, satellite, and IPTV that’s designed for Hybrid STBs, but it’s not shown in the videos.
In the video we’ll find an HDMI stick and a development board based on EN7310, as well as Eagle Kingdom Technologies (EKT) DCP5205 (5:10 in the video), a nice and small set-top box (based on EM730x?) that you can plug directly into your wall socket (no power adapter, no power cable) with a connector for cable, HDMI output, and Wi-Fi that comes with an RF remote. The box runs Solid TV middleware. It’s a full STB, still a prototype, and should hit the market later this year.
There’s some more details on Entropic EM730x page.
