Introduction of a powerful "core" HD player mainstream program
Tag: HD player
This article refers to the address: http://
High-definition players are probably unfamiliar to most HD fans and audio-visual players. As a broadcast carrier for high-definition movies, with convenient and easy operation, powerful decoding capabilities, convenient expansion of audio and video files and convenient resource saving and communication. It has become a must-have machine for audio-visual enthusiasts and HD players.
HD players are increasingly popular with video players
In fact, as early as 2008, there were high-definition player products in China, but before 2008, there were very few readers, and it was only after the end of the year that it began to be widely publicized and popularized. There are two reasons for this. One is that the 2008 Olympic Games in 2008 was the first commercial high-definition broadcast in China, which made more people feel the attraction of high-definition pictures.
High-definition Olympics broadcasts high-definition programming
The second is in 2008, the optical storage format battle of Sony Blu-ray and Toshiba Red Light camp, which lasted for several years, was won by Blu-ray. The unification of large-capacity optical storage formats has enabled the world's major film companies to speed up the release of the latest movie HD version, and the richness of high-definition video and audio resources has been greatly improved. Even since then, some large-scale DVD versions and HD Blu-ray versions have been released at the same time. This also allows movie lovers to access the latest HD movies.
Blu-ray unified provides more HD resources
By 2012, only the high-definition playback of high-definition players has become commonplace for everyone. 3D file playback, intelligent system, free installation software, tablet remote control and even remote control are all implemented in the HD playback body. For powerful computers, we all know that we need a strong CPU, then for HD. For the player, it also needs a strong heart. The following editors will introduce you to the "core" of several major HD players currently on the market.
For the small crab logo on the left below, I believe that friends who know a little about computer hardware or have disassembled the motherboard will have a feeling of deja vu. That's right, this "small crab" almost climbed onto the integrated network card and integrated sound card chip of more than 90% of the motherboard.
Small crab familiar to hardware players
"Little Crab" is named "Ruiqi Semiconductor", the full name of Realtek in English, is an internationally renowned IC professional design company located in Hsinchu, Taiwan. With the R&D and design of integrated circuit products as the enterprise positioning, the most widely known is the integrated sound card and integrated network card.
In the high-definition player market, Realtek's chip solution also occupies a considerable share, especially in the past five years, its program almost occupies an absolute share of the market high-definition player market solution, full-featured, full-format, cost-effective It is the biggest feature of its products, so there are many products in the market.
RTD1073ES solution that once occupied half of the high-definition player
As the latest main program in 2012, RTD1186 can be described as strong performance, 750Mhz clock speed, 512MB RAM, 4GB large ROM, 1186 no matter from high-definition playback, network video, 3D, picture quality, sound effects, integrated applications, overall performance, etc. On the other hand, it has taken a step compared to the previous generation.
Compared with the previous generation mainstream solution RTD1185, RTD1186's chip core processing frequency reaches 750MHz, which is much higher than RTD1185. The memory has also improved a lot, reaching 512MB, and the flash memory is as high as 4GB. At the same time, the USB3.0 input terminal is built in, which can meet the transmission of large-capacity high-speed movies. The most prominent part of the RTD1186 solution is the built-in 3D graphics processing chip, which can harden the 3D image and even allow users to play 3D games smoothly. This is not available in the RTD1185 solution.
Current big hit RTD1186
In addition, due to the greatly improved performance of the chip, the latest high-definition player using the RTD1186 solution has built-in Android system, free to install software, facilitate the expansion of various games and software, and freely browse the network, greatly expanding the HD player. The function.
Sigma Design SMP8642
Referring to the previous RTD series, it is necessary to mention another chip solution brand, Sigma Design, also known as Sigma in China. Its SMP series has been one of the mainstream solutions for the HD player market in recent years, and it is also the main rival of the RTD series.
SMP8642
The SMP8642 has always had a good reputation among high-definition players who are pursuing effects, especially the original menu support and HD source output, making it a dominant place in the competition with rival Realtek.
The following are the main features of the SMP8642/8643:
* Blu-ray players ? IPTV ? Cable ? Network players (DMAs)
Support technology:
* Blu-ray, AVCHD, HDV, DV, DVD- Video, DVD-R/-RW/+R/+RW, SVCD, VCD, CD/-R/-RW, Picture CD (JPEG) media formats
* ATSC, DVB, ARIB and IPTV
* Audio DSP supports wide variety of audio codecs
* Security CPU supports wide variety of conditional access (CA) and digital rights management (DRM) solutions
Video decoding:
* MPEG-4.10 (H.264) BP@L3, MP@L4.0* and HP@L4.0*
* SMPTE 421M (VC-1) MP@HL and AP@L3
* WMV9 MP@HL
* MPEG-2 MP@HL
* MPEG-4.2 ASP@L5 (up to HD, 1-point GMC)
*AVS Jizhun profile@L2.0, 4.0 and 6.0**
* DV (IEC 61834 and SMPTE 314M)
* L4.1 for Blu-ray applications
** up to 20 Mbps for L4.0 and 40 Mbps for L6.0
marvell88DE3010
Compared to the previous two programs, I am afraid that most HD players are relatively new to this third solution.
Marvell Technology Group [1] (Marvell Technology Group), an American chip manufacturer specializing in manufacturing storage, communications and consumer electronics ICs. Founded in 1995 in Santa Clara, California, the company ranked 18th among the top 20 semiconductor manufacturers in the world in 2010.
Marvell 88DE3010 is also an unsuccessful chip. The reason is that Marvell design 88DE3010 is not for the player market, but for the Blu-ray player market. The rogue 88DE3010 does not have an integrated servo chip, so it is defeated by other Blu-ray chips. The servo-player market is more than enough.
88DE3010
Take a look inside 88DE3010:
The hardware configuration should be regarded as a luxury lineup. In addition to the dual core, the decoding of the video, the decoding of the audio, and the decoding of the picture are all realized by hardware. Especially for the audio DSP, the chip has the function of the audio decoder. Pay special attention to the video transmission processing of QDEO, which is why other chips cannot be compared with this chip. The same source can be better with QDEO transmission processing, which is the most important reason why the Marvell 88DE3010 can be used as a high-end player. With the DSP of the audio (the frequency of 500M Hz is still quite strong), then Dolby TrueHD, DTS MA is no problem. In video processing, the 88DE3010 supports dual-channel HD decoding, which supports 3D decoding and playback.
Although it entered the hard disk HD player market late, with the excellent audio and video performance of the 88DE3010, it is gradually favored in the middle and high-end products market, and more and more products adopting this solution appear.
