In recent years, the gimmicks of 4K TVs have flooded the entire TV market. Several Japanese manufacturers have launched corresponding 4K TVs, and high prices have appeared under high resolution. But because of this 4K, it has brought business opportunities to H.265 chip makers.
First-tier chip manufacturers are doing their best to develop H.265 codec. In 2013, 4K & TImes; 2K display will bring new development to the TV industry. Not only are brand factories actively expanding their layout, including heavyweight chip manufacturers such as STMicroelectronics, Qualcomm and Broadcom, but also stepping up research and development of a new generation of video codec standard-H. 265 (HEVC) chip solution to improve the performance of video codec and solve the challenge that the existing H.264 codec is not capable of 4K & TImes; 2K pixel processing.
Chen Xicheng, marketing manager of STMicroelectronics, believes that the expansion of 4K & TImes; 2K panel resolution to four times that of FHD will boost the experience of using naked-eye 3D functions.
Chen Xicheng, technical marketing manager of STMicroelectronics, said that after Smart TV, 4K & TImes; 2K TV is expected to become the new focus of the industry, which has attracted overweight investment from the world's top brands, panel suppliers, chip and content companies. However, the surge in the resolution of 4K × 2K panels has also brought a comprehensive impact, driving the innovation of the TV ecosystem, especially the compression performance of the H.264 (AVC) codec has become stretched, leading to the next generation of H.265, or The standard called HEVC (High Efficiency Video Coding) is rising rapidly.
The H.265 standard is expected to be officially finalized in the first half of 2013, and then to take over the status of H.264 in the 4K × 2K development boom. It is reported that H.265 improves the compression ratio to twice that of H.264 through the advanced picture prediction mode and precise coding architecture, reaching 400: 1 level, in addition to shortening video compression time by 50%, reducing system workload and power consumption In addition, it has greatly increased the utilization rate of network bandwidth, helping telecommunications operators and cable TV operators to place more content services under cable bandwidth to create revenue.
At this stage, the first-tier chip manufacturers have scrambled to unveil a new generation of H.265 codec research and development plan, the card bit action frequently. Among them, STMicroelectronics will use 28 nanometers (nm) advanced manufacturing process in 2013 to create H.265 chips, which will be used with its TV system single chip (SoC) to build a complete 4K × 2K TV solution. Chen Xicheng further emphasized that with the increase in 4K × 2K TV shipments, the company also plans to integrate the H.265 chip into the TV SoC in 2014, reducing the printed circuit board (PCB) footprint and creating better Cost-effectiveness.
Coincidentally, Qualcomm and Broadcom are also rapidly developing H.265 chips. The former has added the H.265 codec function to its latest multi-core mobile processor to improve the efficiency of bandwidth usage; the next step will be to import TV dedicated processors to attack 4K × 2K TV business opportunities. As for the latter, for home gateways (STBs) and digital set-top boxes (STBs) and other applications, plus investment in H.265 video codec technology research and development, the relevant chips are ready to go.
At the same time, since 4K × 2K content production cannot keep up with the development speed of hardware such as panels and codecs, STMicroelectronics will also mass produce frame update rate conversion (FRC) chips suitable for 4K × 2K applications in 2013. To make up for the shortcomings that cable or content providers can only provide 1,080p video in the short term. In addition to the company, chip vendors such as Pixelworks, Qijing Optoelectronics and Novatek are also actively developing FRC solutions to seize the market opportunities.
Chen Xicheng analyzed that even if the TV panel is upgraded to 4K × 2K resolution, if the content source is still full high-definition (FHD), it must be processed through the FRC chip to fill up the insufficient pixels in the 1,080p file to fully display 4K. × 2K display function value.
On the other hand, in order to strengthen the 4K × 2K panel and TV SoC signal communication mechanism, panel makers have also invested heavily in the design of a new generation of timing controllers (T-CON), and interface chip suppliers have turned to multi-serial low-voltage differential signals (LVDS), V-by-One HS or eDP (Embedded DisplayPort) and other high-speed image interfaces. Chen Xicheng also revealed that STMicroelectronics will launch LVDS / V-by-One HS dual-mode chips for 4K × 2K TVs to help brand customers achieve flexible design solutions. In addition, for 4K × 2K displays, they will focus on developing eDP products. To optimize connectivity with PC.
H.265 introduction:
H.265 is a new video coding standard formulated by ITU-T VCEG after H.264. The H.265 standard revolves around the existing video coding standard H.264, retaining some of the original technologies, while improving some related technologies. The new technology uses advanced technology to improve the relationship between code stream, encoding quality, delay and algorithm complexity to achieve the optimal setting. Specific research contents include: improving compression efficiency, improving robustness and error recovery capabilities, reducing real-time delay, reducing channel acquisition time and random access delay, and reducing complexity. Due to algorithm optimization, H264 can achieve standard definition digital image transmission at a speed lower than 1Mbps; H265 can achieve 720P (resolution 1280 * 720) ordinary high-definition audio and video transmission at a transmission speed of 1 ~ 2Mbps.
