In recent years, 4K TV's head is full of full TV markets, and several manufacturers in Japan have launched the corresponding 4K TV, and high resolution also has high price. However, due to this 4K, it brings business opportunities to H.265 chip aggress.
The first-line wafer big factory is fully R & D H.265 codec. In 2013, 4k2k showed a new development of the TV industry, not only the brand factory actively launched the layout, including the weight-scale wafer merchants such as Semiconductor, Qualcomm and Bo Tong, but also stepped up research and development of a new generation of video codec standards --H. 265 HEVC) Wafer scheme to improve video codec efficiency, solve the challenge of existing H.264 codec can't be competent in 4k2k phenologumes.
Be
Chen Xizheng, a semiconductor marketing manager, believes that the 4k2k panel resolution is amplified to FHD four times, which will be able to promote the use of naked eye 3D function.
Chen Xizheng, a salesman of STMic Technology, said that after smart TV (Smart TV), 4k2k TV is expected to become a new focus of industrial, attracting a few large brands, panel suppliers, wafers, and content owners. However, 4K × 2K panel resolution also brings a comprehensive impact, affecting TV ecosystem innovation, especially the compression effectiveness of the H.264 (AVC) codec, which has been stretched, and the next generation H.265, or The High Efficiency Video Coding standard is rapidly rising.
The H.265 standard is expected to be officially decided in the first half of 2013, thereby replacing the status of H.264 in the 4k × 2k development boom. It is reported that H.265 increases the compression ratio to twice the compression ratio to H.264 through the advanced picture prediction mode, reaching 400: 1 level, in addition to 50% video compression time, mitigation system work burden and power consumption In addition, there is also a substantial increase in network bandwidth utilization, help telecommunications, cable TV operators, place more content services to create revenue.
At this stage, the first-line wafer large factory has been struggling to reveal the new generation of H.265 codec research and development plan, the card position moves frequently. Among them, the semiconductor will use 28 NM (NM) advanced processes in 2013 to create a H.265 wafer, thereby with a single wafer (SOC), a complete 4k × 2K TV solution. Chen Xicheng emphasized that with 4K × 2K TV shipments climbed, the company also organized H.265 wafer in the TV SOC in 2014, reducing the printed circuit board (PCB) placeholder space, and creates better Cost-effectiveness.
Coincidentally, Gao Tong, Boyong is also a rapid horses to develop H.265 wafer. The former has installed H.265 codec function in the latest multi-core action processor, enhances the frequency wide use efficiency; the next step will import TV dedicated processor and attack 4K × 2K TV business opportunities. As for the latter, it is also for applications such as Home Gateway, Number Machine (STB), and Code Investment H.265 Video Code Technology R & D, related wafers have been honest.
At the same time, since 4K × 2K content production is not on the panel, the hardware of the codec is the development speed of the codec, so that the semiconductor will also be used in 2013 to add picture update rate (FRC) wafers for 4k × 2K applications. Make up the cable TV or content owner can only provide 1,080p video in the short term. In addition to the company, Dingyun Technology (PixelWorks), Wonderful Optoelectronics and Linkai and other wafer manufacturers have also actively developed the FRC program and the card market.
Chen Xicheng analysis, even if the TV panel upgraded to 4K × 2K resolution, if the content source is still full high quality (FHD), it must pass through the FRC wafer, fill in the 1,080p file insufficient pixels, and can fully display 4K × 2K display value.
On the other hand, in order to strengthen the 4K × 2K panel and the TV SOC signal communication mechanism, the panel factory also puts into design a new generation of timing controllers (T-CON), and interface wafer supplier offensive multi-string low voltage differential signal (LVDS), high-speed image interfaces such as V-BY-One HS or EDP (Embedded DisplayPort). Chen Xicheng also revealed that the semiconductor will launch the LVDS / V-BY-One HS dual-mode wafer for 4k × 2k TV, to help brand customers to achieve an elastic design, and another in the 4K × 2K display, the development EDP product is mainly , Optimize the connection between the PC.
H.265 Introduction:
H.265 is a new video coding standard established after ITU-T VCEG followed by ITU-T VCEG followed. The H.265 standard surrounds the existing video coding standard H.264, reserves the original technologies, and improves some related technologies. New technology uses advanced technology to improve the relationship between code stream, coding quality, delay and algorithm complexity, reaching optimization settings. Specific research contents include: increasing compression efficiency, improving robustness and error recovery capabilities, reducing real-time delays, reducing channel acquisition time and random access delay, reducing complexity, etc. Since the algorithm optimization, the H265 can be achieved at a speed of less than 1 Mbps, and H265 can realize the transfer of 720P (resolution 1280 * 720) to transmit 720P (resolution 1280 * 720) to transmit the transmission speed of 1 to 2 mbps. , Reading the full text, the technology area
