The DVR Software GUI

The DVR Software GUI is one determining factor of the user-friendliness of a specific DVR Application. Less is better when it comes to this element. It's straining in the eyes and kind of confusing to look at a crowded or a not-so-very-well organized user-interface. Would you go for a complicated GUI with lots of buttons filling out the screen or a simplified version offering the same functions. A sound mind will surely go for the simplified version. However, simplifying the GUI is not enough. We need to take into account the organization of the buttons - they should be arranged throughout the screen in the most orderly way as possible.

Here are just some of the better DVR Software GUIs in my opinion.

The DVR DDNS resolves this problem.

The DDNS Service works to track your IP address and report it back to the DDNS Provider. The DDNS Provider then assigns an extension (that's unique to you) to a publicly available Domain. Each time you type that Domain name into a browser, the DDNS Service translates what you've typed back to the current IP address of the internet that your DVR is located at.

MPEG-4 vs H.264 Video Compression Technology

Despite its pristine technology, why is it that a lot of CCTV Installers still prefer MPEG-4 DVRs over the more advanced H.264 DVRs? Would there be anything (functions or processes) that you can do better with MPEG-4 Videos that you cannot seem to execute falwlessly with H.264 Videos? Do you believe that the MPEG-4 Video Compression Technology will soon be obsolete and casted off the CCTV market thru the advancement of the H.264 Video Compression Technology? Your comments, opinions, relevant knowledge and information are mostly welcome.


Stated below is a General Comparison of the MPEG-4 and H.264 Video Compression Technologies:

Overview of MPEG-4 Encoding Format:

• MPEG-4 is a standard used to compress audio and visual data. The MPEG-4 standard is generally used for streaming media and CD distribution, video conversation, and broadcast television. MPEG-4 incorporates many features of MPEG-1, MPEG-2 and other related standards.

• MPEG-4 is still a developing standard and is divided into several parts. The standard includes the concept of “profiles” and “levels,” allowing a specific set of capabilities to be defined in a manner appropriate for a subset of applications.

• MPEG-4 is able to crunch massive video files into pieces small enough to send over mobile networks. While these blurry pictures are unlikely to persuade millions of people to upgrade immediately their mobile phones but holds enough promise for future.

• Perhaps more important are the interactive features that MPEG-4 offers. The video functions almost like a Web page, but allowing people to interact with the picture on the screen or to manipulate individual elements in real time.

• MPEG-4 also allows other types of content to be bundled into a file, such as video or images. These files require special software to play.

• MPEG-4 would allow the interactivity of the video which may open potential to do far more than just point and click at links on the screen. Individual elements of the video like a character, a ball in a sporting event, a rocket ship in a science-fiction epic can exist in a separate layer from the rest of the video. This could allow viewers to interact with these elements somehow, even changing the direction of the story.

Overview of H.264 Encoding Format:

• Also known as MPEG-4 Part 10 or AVC (for Advanced Video Coding).

• Poised to become the next standard for format of convergence in the digital video industry regardless of the video playback platform . Big Internet players like Google/YouTube, Adobe, and Apple iTunes are all backing this cross-platform format.

• H.264 standard is jointly maintained with MPEG so that they have identical technical content.

• The intention behind H.264/AVC project was to provide good video quality at substantially lower bit rates than previous standards. An additional goal was to provide enough flexibility to allow the standard to be applied to a wide variety of applications on a wide variety of networks and systems.

• H.264/AVC/MPEG-4 Part 10 contains Multi-picture inter-picture prediction including the features like using previously-encoded pictures as references in a more flexible way than in past standards, allowing up to 32 reference pictures to be used sometimes.

• H.264 provides quarter-pixel precision for motion compensation enables very precise description of the displacements of moving areas. For chroma the resolution is typically halved both vertically and horizontally, therefore the motion compensation of chroma uses one-eighth chroma pixel grid units.

• H.264 provides six-tap filtering for derivation of half-pel luma sample predictions, to lessen the aliasing and eventually provide sharper images.

• H.264 provides flexible interlaced-scan video coding features, includes Macro block-adaptive frame-field (MBAFF) coding, using a macroblock pair structure for pictures coded as frames, allowing 16×16 macroblocks in field mode compared with 16×8 half-macroblocks in MPEG-2. An enhanced lossless macroblock representation mode allowing perfect representation of specific regions while ordinarily using substantially fewer bits than the PCM mode. Picture-adaptive frame-field coding, allowing a freely-selected mixture of pictures coded as MBAFF frames with pictures coded as individual single fields (half frames) of interlaced video.

• H.264 is more attractive for video network delivery and for delivery of HD, high definition video.

• H.264 or AVC is an open format with published specification and is available for anyone to implement.

Overview

The following diagram illustrates how text may be inserted onto the video.




The DVR listens to incoming TCP/IP connections from other devices connected to the network. These devices may be a Point-Of-Sale terminal, an access control system or any application capable of sending data via TCP/IP.

Once the DVR receives data, the DVR authenticates the sender and validates the data. If valid, the text information is superimposed onto the video of the camera or cameras specified by the sender. Simultaneously, the text information is stored to disk with the video, and stored to a database for search purposes. Search may be performed on the DVR or remotely via a client software application.
