I. rec.709 HDTV color EncodingRec.709 defines the YCbCr color encoding. Unfortunately, unlike sdtv's range factor definition, YCbCr encoding is divided into two types. One is used for small image (sdtv) encoding, and the other is used for large image (HDTV) encoding.

What is HD?
"High Definition" in English, meaning "high resolution ". The definition of HD has four meanings: hd TV, HD device, HD format, and HD movie.

In the past few years, HDTV has achieved great success thanks to the promotion of the consumer electronics market and the positive transformation of CRT TVs into LCD and plasma TV screens. With the use of HDTV in the video surveillance field, the definition of SD, HD, and full HD in monitoring basically follows the definition of HDT
Comparable vs. Comparator
Comparable and Comparator are two interfaces provided by Java core APIs. From their names, we can roughly guess that they are used to compare some things in some way. But what are the differences between them? The following two examples answer this question. This example is used to compare the HDTV size. After reading the following code, you will be clear about how to use Comparable and Comparator.1. Comparable

This is achieved through Signal-to-Noise RatioType (SNRProfile) subsets are implemented by hierarchical coding, that is, as the receiving conditions become worse, the image quality is moderately degraded to prevent the inherent "Cliff effect" of digital b
standards have been developed and are currently being developed for MPEG:
MPEG-1: the first official Video audio compression standards, followed by the Video CD is adopted, the audio compression level 3 (MPEG-1 Layer 3) referred to as MP3, it has become a popular audio compression format.
MPEG-2: broadcast quality video, audio, and transmission protocols. It is used in digital TV-ATSC, DVB, ISDB, Digital Satellite TV (such as DirecTV), digital cable TV signal, and DVD video disc technology.

By now, all analog TVs have been eliminated, and TV Station shooting, recording, and editing devices have also been replaced, what people will see on TV screens will be high-definition TV pictures and more functions. HDTV will bring TV into a new era.Someone asked if the current digit
, and 858 sample points can be sampled for each scan line. For the NTSC system, the sample points are. Because each line of the TV signal includes a certain synchronous signal and a return signal, there are not so many valid image signal sample points,CCIR 601 specifies that for all standards, the valid sample points for each row are 720 points. The number of valid lines per frame varies according to different standards (PAL and SECAM are 576 rows, and NTSC is 484 rows ),CCIR defines 720x484 for
to be "HD" and "Full HD. It is not difficult to find that their image quality is uneven, and some images are of the same quality as ordinary plasma and liquid crystal. This is because sellers confuse the video resolution with the display resolution. In fact, the two are not necessarily related. The video resolution is determined by the camera shooting and the later or compressed encoding settings, the resolution of the display is determined by the manufacturing process.
