Digital video, which has many formats, is a very beneficial tool. Companies can take advantage of its neglected power for internet marketing (the process of promoting, selling and distributing a product or service 24 hours a day, 7 days a week on the Internet). There is no better way to sell in a global market that buys 24 hours a day with a well-designed website with this great tool. She is also involved in a lot of litigation and quickly reaches audiences around the world.

In the following paragraphs, my goal is to help you understand digital video with respect to CCTV systems and its many formats.

In simple terms, digital video can be defined as a video that has been recorded with the help of software and stored digitally in a computer. A video surveillance system is a computer. This digitized information can be controlled from a computer and displayed directly on a computer screen.

All of the current digital video file formats, listed below, are based on PCM or Pulse-Code modulation. PCM is a digital representation of an analog signal where the amplitude of the signal is sampled regularly at uniform intervals, then quantized into a series of symbols in digital form (usually based on a binary code).

Here is a brief catalog of digital video file types to better understand how it is used.

CCIR 601 (or RE 601) is a file used for broadcast television stations due to the conversion of analog and digital television. This digital video file format converts and encodes the interlaced analog video signals into digital video.

Previously, television commercials were first broadcast on analogue and then on digital tape. Today, television commercials can be distributed electronically over wireless networks using digital video technology.

Services such as SpotMixer allow businesses to create their own online ads and distribute them on a variety of media, including TV and Internet.

MPEG-4 is ideal for the online distribution of large videos and videos recorded in flash memory. This is a digital format used for iPod video and download on YouTube and other social media networks, but keep reading.

MPEG-2 (used for DVDs) is a digital file format used to create DVDs. An MPEG-2 digital video file burned to a DVD will play the video on a DVD player and on a computer, provided that the computer has the ability to play DVDs. Some computers with older DVD technology will have difficulty reading DVDs burned with newer technology.

MPEG-1 is used for video CDs and was the first mass-marketed digital video format. It is rarely used today, but occasionally appears. Many DVD players will read MPEG-1, but not everyone can read this digital file format.

H.261 was the first truly practical digital video coding standard. In fact, all subsequent international coding such as MPEG-1, H.262, MPEG-2, H.263, MPEG-4, and H.264 (MPEG-4, Part 10) rely heavily on the H.261 design. which is now rarely used.

H.263 is a video codec standard originally designed as a low-bandwidth compressed format for video conferencing. H.263 has since found many applications on the Internet: much of the content Flash Video (used on sites such as YouTube, Google Videos, MySpace, etc.) is encoded in this format.

The original version of Real Video (which I recommend you leave) was based on H.263 until the release of Real Video 8. In other words, I'm talking about H.263 so that you can see the inheritance.

H.264, also known as MPEG-4 Part 10 or AVC, is the next enhanced codec developed for sharing digital video over the Internet. The H.264 protocol provides a significant improvement in capabilities beyond the H.263 protocol. The H.263 standard is now mainly considered as an inherited design (although it is a recent development).

Most new videoconferencing products now include H.264, H.263 and H.261 capabilities. Primeau Productions uses H264 digital video in Quicktime format to send to webmasters to encode Flash video on customer websites.

In summary: The above files are created using computers, including CCTV systems, and can be viewed with the help of video editing software and video editing software. digital video file converters.

H.264 technology is an excellent starting file format for creating Flash videos. Video editing software can produce various H.264 sizes and be used in different ways:

1. A source digital video file to create a Flash video for your website
2. A digital video file that can be emailed
3. A digital video file that can be uploaded to social media such as YouTube, Yahoo and Viemo
4. To view a converted CCTV video codec in court

Flash video is a digital video player based on the web. It is cross-platform, which is why I recommend using it for streaming digital video content on your website.

Although many editing programs such as Final Cut, Vegas, and Premiere are able to export finished video productions in Flash (.FLV) format, creating a complete Flash video does not limit itself not to a video file.

When a digital video file is created as an H.264 file (encoded to specifications less than 10 minutes and 1Gig) and loaded on YouTube, Yahoo, MetaCafe, and Viemo, the H.264 file is converted to Flash video for the download process.

Many services that publish PR videos on their websites do not accept Flash Video (.FLV) files anymore. HTML 5 is out and almost takes control of Flash, but it still has some way to go.

If you want to publish a Flash video to your website, you must have the following components in addition to the .FLV video file:

1. The part.html – the html web page that loads the flash drive
2. The part.swf – the compiled flash file for the web (contains the flash video player)
3. The part.flv – the actual video file of the flash drive
4. ac_runactivecontent.js: the javascript file that loads the reader into browsers.

Adobe, a non-video-based video production software called Flash, is used to create graphics and videos for websites.

Flash Video is a file format used to stream video over the Internet with the help of Adobe Flash Player. The format is quickly imposed as the format of choice for integrated video on the Web. Notable users of Flash Video include YouTube, Google Video, Yahoo, MetaCafe, Viemo, Reuters.com and many other news providers.

Flash video is visible on most operating systems, via the widely available Adobe Flash Player.

Finally, Theora standardized is still in development and is not used very often, but nevertheless deserves to be mentioned to complete your understanding of the different file formats available today.

An understanding of file formats and multiple uses of digital video is an important asset.
