The clear image and shocking sound effects brought by digital television technology are creating user's home entertainment expectations, but even well-informed users may not realize that in a wide variety of AV systems, simulation technology is to create the reality that most people expect, The key to an immersive high-definition (HD) experience.
Because the high-definition (HD) video, audio, and interconnect interfaces require significantly more signal processing performance than standard-definition (SD) TVs, Analog Devices introduced the AdvanTIvTM Advanced Television (ATV) family of solutions. To meet the most difficult multi-format ATV design challenges, it provides low-cost analog signal, digital signal and mixed signal solutions.
Advanced TV: Meeting Multiple Design Challenges
According to DisplaySearch's research report, HDTV's sales growth from 2005 to 2010 is expected to grow at a CAGR of 44%. The rise in HD popularity has brought many design challenges that standard definition (SD) television technology cannot solve. These challenges include: digital content protection, complex HD signal routing, increased flat panel display, surround sound with 7.1-channel surround sound, and connectivity issues with long cables and new interface standards. Analog Devices addresses the challenges of composing all electronic devices in the advanced television ecosystem, including HD DVD players, digital video recorders (DVRs), audio video receivers (AVRs) and HD camcorders, and HDs that ensure delivery of digital content to millions of homes High fidelity signal interconnect technology.
ADI's AdvanTIvTM Advanced TV Series Solution: Connectivity for Audio, Video, and HD Environments
The essence of a true home theater experience is a thrilling sound, clear images, and seamless system connectivity. ADI's AdvanTIv Advanced TV Series solutions include the following product and design support offering a wide range of system-level features:
Audio: Even though today's flat-panel HDTVs provide users with unprecedented flexibility when configuring their entertainment centers, manufacturers still face many very important design challenges in order to match HD video performance and HDTV's beautiful appearance to audio performance. Ironically, it is the highly anticipated ultra-thin, wall-mounted LCD TVs and plasma TVs themselves that limit the selection and placement of the best speakers and the efficiency of power amplification. To solve this problem, ADI's advanced audio processor provides HDTV developers with a variety of improved audio options, ranging from basic speaker equalization to sophisticated surround sound virtualisation. In addition, Analog Devices' small package-sized Class-D audio amplifiers provide users with the power they need to experience the same audio experience as large TV speakers. All audio subsystems can seamlessly access ADI's video processing subsystem.
Analog Devices Expands Its AdvanTIv Advanced TV Series Solution, Introducing the ADAV43x2 and ADAV44x2 Advanced TV Audio Processors, which feature a variety of features including automatic sound control, dynamic bass change, multiband equalizers, and audio and video synchronization Up to 200 ms stereo delay memory. TV manufacturers have also begun to use ADI's audio processing solutions to solve many related problems, such as adjusting the volume during commercial hours or when television viewers change channels. Analog Devices also announced today the ADAU1590, ADAU1592 and ADAU1513 Class D audio amplifiers, which provide twice the 18W and 0.005% THD+N, making it ideal for connecting to a TV audio processor.
Video: HDTV users expect to maintain a very clear video quality forever, but when faced with "information loss" or image distortion when wireless HD connection occurs, the home theater's sharpness will drop. Many users want to simply add a wireless HD connection to solve this problem but do not realize that high-performance image compression is the key to guaranteeing their image quality. The main reason for the degradation of a video quality found in many wireless video systems is that most image compression formats cannot provide true lossless compression in real time at consumer prices. These formats are also very susceptible to data flow interruptions, and data flow interruptions often occur in wireless environments. ADI's WavescaleTM image compression technology, part of ADI's Advantiv Advanced TV Series solution, can even provide HD picture quality in noisy wireless environments, radically reducing possible errors in wireless transmission channels. The impact of video. ADI's ADV216 Wavescale Video Compression Codec (CODEC), introduced today, delivers wireless and wired HD video in consumer applications.
Connectivity: A common problem with HD home entertainment systems is the confusion caused by the variety of remote controls required to control televisions, DVD players, cable or satellite TV set-top boxes, and mobile peripherals such as video recorders and portable media players. . Users must manipulate different menu configurations and feature options, and multiple remote controls can be confusing and require more batteries and frequent battery replacement. Analog Devices has the industry's broadest portfolio of HDMI connectivity solutions and recently introduced the ADV7520NK HDMI v1.3 compliant transmitter for portable media and DVD players, video recorders and other mobile HD multimedia devices. The ADV7520NK, the newest member of ADI’s Advantiv Advanced TV Series, is the industry’s first HDMI transmitter with built-in support for Consumer Electronics Control (CEC). It reduces component count, simplifies design complexity, and speeds time-to-market for portable HD devices, eliminating the need for design engineers to develop separate CEC support channels. This new transmitter consumes half the power of similar products in its operating mode and only 10% of the similar products in standby mode, extending the battery life of portable consumer electronics.
In summary, Analog Devices offers a wide range of industry-proven solutions and corresponding products for ATV applications, enabling customers to enjoy a comfortable experience and enjoy using the latest HDTVs, DVD players, digital cameras, audio and video receivers, camcorders There is also a cable and satellite TV set-top box.
The so-called portable projector, also known as pocket projector, mainly through the 3M LCOS RGB three-color projector and decoding technology, the traditional huge projector is compact and portable, making the projection technology closer to life and entertainment.
Advantages compared with traditional projectors:
1. Small size, light weight, easy to carry.
2. Low calorific value and low noise.
3. The price is relatively cheap.
4. Most models support wireless connection through software projection.
Applicable fields:
1. Replace some functions of TV: some machines can have built-in CMMB function, or can be directly connected to the set-top box to put TV, which can be used as a 21-inch TV during the day and a 60-100-inch TV at night (Note: Because of lumen and resolution issues, lumens during the day If the degree is not enough, it must be projected at a close distance) to achieve the effect of home theater; it is convenient to move and break through the traditional film and television space. Even if you are on the mountain, you can also share today's TV series, movies, and MTV with your lover.
2. Business trip: Portable projectors are easy to carry because of their small size and light weight. When you need to display computer content or mobile phone content, you only need to connect the portable projector to achieve the demonstration effect.
3. Private space: For dormitory beds or small private spaces, in the absence of a computer, you can use a portable projector to project the content of your mobile phone to watch video pictures, etc., without staring at the mobile phone at close range.
