the width and height ratio of viewport widths and heights, a 16:9 scale display can be defined like this aspect-ratio:16/9device-aspect-ratio: like Aspect-ratio, Aspect ratio color based on device render plane width and height: the number of bits per color, for example, MIN-COLOR:16 detects whether the device has a 16-bit color Color-index: The number of colors in the device's Color index table, and the value must be a non-negative integer monochrome: Detects the number of bits used per pixel i

Many mobile phone audio and video applications in the market, but the need for network bandwidth is not the same, if the high bandwidth, mobile phone video 3G network is a bit miserable.At present, there are four main types of network: ADSL dial access, optical fiber access, 3G dial-up access, LAN.ADSL Dial access mode is an asymmetric network access, downstream traffic usually has 2Mbps, 4Mbps, 6Mbps, and upstream traffic is usually 512kbps, that is, the upstream rate and downlink rate is asymm

It is a standard digital TV display mode with 750 vertical scanning lines, 720 visible vertical scanning lines, resolution of 1280 × 720, line by line/60Hz, the line frequency is 45 kHz. D5 is in the 1080p format. It is a standard digital TV display mode, with 1125 vertical scanning lines, 1080 visible vertical scanning lines, and a resolution of 1920x1080

component interfaces, do not have an internationally harmonized standard, and the most common are Japan's D terminals, European SCART terminals and US three-wire terminals. China is currently using the United States, a three-wire terminal, this terminal is the United States EIA (Electronic Industry Association) standard EIA-770.2A provisions. According to this standard, down to 480i to 720p signal is the use of this terminal transmission, and there i

Some technical video resources2014 MarchRecently, some interesting video resources have been found on some websites abroad. Usenix Video of the conference. Usenix, formerly known as the Unix Users Group, can download all of the conference video Https://www.usenix.org/conferences/multimedia from 2008 to the present on its website, typically 480p. Because I personally prefer to read Usenix paper, it is more biased industry. So I like to watch their speeches. Google developers at Yout

elements in the JSONArray are all jsonobjects. Another method of parsing: json data is like this, {"Type": ["terrorism", "plot"]}, In this form of analysis, braces are parentheses. That is, the array is displayed in the form of a key-value pair. The outermost layer is a JSONObject, and the KEY corresponds to JSONArray. It should be like this: JSONArray jsonArrayType = JSONObject.getJSONArray("type");String[] type = new String[jsonArrayType.size()];for (int j = 0; j In this way, the desired dat

conferencing for universal image transmission, which is part of the ITU H.261 protocol. As you can see, the number of chroma samples per resolution and the number of rows are half the corresponding resolution. Yes, because this standard takes into account the performance of the camera and the performance impact of transmission, the use of the interval pixel sampling and interlaced scanning mechanism, and the interval pixel sampling through interpolation to complement.But these parameters seem t

any new technology can achieve a smaller capacity of higher definition? That was the later launch of the MPEG-2.MPEG-2 This standard is the first popular global compression technology, the standard set Time is 1994 (VCD Standard is 1993). Although it has been over more than 20 years, it is still one of the most important video compression formats today. In addition to a large number of DVD products, more important is the current radio and television field of digital TV DVB-T standard, still usi

should I emphasize that it is a concept on a software system? Because when you buy a cell phone, you often hear another parameter called PPI, which is the pixel density on the phone screen, but this is the concept of physics, it is an objective existence will not change. DPI is a user-specified value after the software references a physical pixel density, which ensures that the physical pixel density within a range uses the same value on the software. This will help with our UI adaptation.For e
