Bandwidth efficient frame design

Even with 16X FSAA enabled, frame rates start at a respectable 60 fps, and remain above 20 fps even when displaying the most complex frame. It is particularly in these circumstances that the ability to efficiently perform de-interlacing may be jeopardized.

Bits vs Bytes In video surveillance, bandwidth is typically measured in bits but sometimes measured in bytes, causing confusion. The choice for Reed-Solomon coding as the outer error correction code is based on the observation that the Viterbi decoder used for inner convolutional decoding produces short error bursts when there is a high concentration of errors, and Reed-Solomon codes are inherently well Bandwidth efficient frame design to correcting bursts of errors.

The best known tile-based renderer company, PowerVR, performs Hidden Surface Removal HSR onchip by introducing a pre-rendering pass and filling the z-buffer with values that track which pixels are visible.

Bandwidth Per Camera Bandwidth is typically measured per camera and the amount of bandwidth each camera needs can vary significantly. Although the guard interval only contains redundant data, which means that it reduces the capacity, some OFDM-based systems, such as some of the broadcasting systems, deliberately use a long guard interval in order to allow the transmitters to be spaced farther apart in an SFN, and longer guard intervals allow larger SFN cell-sizes.

RSVP can be deployed in existing networks with a software upgrade. When you clear this check box, the cutoff frequency is specified on the block dialog through the Filter Cutoff frequency Hz parameter. However, in many competitive marketing environments, the success of a video processing device does not merely depend on the processing power of the device, but also depends on the cost of the device.

For instance, traffic with an IP Precedence field value of 7 gets a lower weight than traffic with an IP Precedence field value of 3, and thus has priority in the transmit order. The apparatus of claim 24, wherein the graphics processing module includes multiple texturing units associated with the plural inputs and the other input.

This includes the market for handheld 3D graphics and multimedia hardware such as mobile phones, PDAs, Tablet PCs, game consoles and in-car infotainment and navigation systems. Flow RED is used to deal with such flows. With interlaced video, alternate lines of the video image are sampled at alternate moments in time.

As a part of the Mali graphics cores, Falanx ships a full set of ARM optimized pre-verified software stacks, including all Khronos APIs, and the following software components: An apparatus according to claim 13, wherein the performing of the operation comprises de-interlacing the principal video stream.

You can also define priority and custom queuing at the VC or subinterface level. Useful for one-manufacturer systems.

AES E-Library

WANs can deliver the same or more bandwidth as the LAN but the costs tend to be significantly higher in the order of 10 or x more expensive per bit because these networks need to run great distances and across many obstacles. Of course, if you increased both the resolution AND the frames per second of the cameras, your requirements would increase even further.


For example, the recorder might be in a rack in an IT closet but the viewer i. In one implementation, different texturing units are assigned to the principal video stream and the video sub-stream, respectively.

Falanx targets semiconductor SoC vendors delivering platform and infrastructure products for mobile communication and computing. However, OFDM can be combined with multiple access using time, frequency or coding separation of the users.

For baselining a network, you can use RMON probes and an application such as Traffic Director to develop a good understanding of traffic characteristics. WRED uses a minimum threshold for each IP precedence level to determine when a packet can be dropped.

You can also use rate enforcement with the existing data-link connection identifier DLCI prioritization feature to further improve performance in this situation.

It was designed to give strict priority to important traffic. Conforming traffic can be transmitted, and exceeding traffic can be reclassified to a lower IP precedence setting and then sent to the next CAR statement for additional conditions.

This was briefly described in the "Classification" section, earlier in this article, as it pertains to classification. Am I interpreting this feature correctly? On the other hand, a video sub-stream refers to auxiliary video data that can be presented along with the video frames of the primary video stream.

Space diversity[ edit ] In OFDM-based wide-area broadcasting, receivers can benefit from receiving signals from several spatially dispersed transmitters simultaneously, since transmitters will only destructively interfere with each other on a limited number of sub-carriers, whereas in general they will actually reinforce coverage over a wide area.

For instance, methods, apparatuses, and computer readable media are described for de-interlacing a principal video stream at the same time that at least one video sub-stream is combined with the principal video stream.

Jumbo frame

In the latter case, the graphics module can constitute a graphics processing unit GPU card that can be detachably coupled to the computer, game console, or other kind of device. More specifically, the system shown in FIG.

This allows the router to make the decision on which packets get dropped when the queue depth increases. This allows for finer granularity in the prioritization and queuing of traffic, and provides more control over the traffic flow on an individual VC. Cisco IOS software QoS features give VoIP traffic the service that it needs, while providing the traditional data traffic with the service that it needs as well.

Bandwidth Fundamentals For Video Surveillance

Without FSAA, the tile-based architecture requires less bandwidth than immediate mode for the geometry complexities that can be expected by advanced mobile games, which will be about k polygons, while the Mali architecture is even more efficient.

Then, in a second pass, the chip can render and fetch the textures for only those visible pixels. Real-Time Transport Protocol header compression increases efficiency for many of the newer voice over IP or multimedia applications that take advantage of Real-Time Transport Protocol, especially on slow links.

The same can be seen when you increase the FPS of the cameras instead. Specify bandwidth from input port When you select this check box, the bandwidth of the IIR filter is input through the BW port.Towards bandwidth efficient TDMA frame structure for voice traffic in MANETs Abstract: Time division multiple access (TDMA) based channel access is one of the most widely used mechanisms in Mobile Ad hoc Networks (MANET) with its efficient channel access and collision free transmissions at its core.

For GPUs, memory compression isn't theoretical: they use it to compress frame, depth and stencil buffers to save bandwidth. Overall performance (i.e.


frame rate) improvement is typically % AFAIK. In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, used in applications such as digital television and audio broadcasting, DSL internet access, wireless networks, power line.

Stack Exchange network consists of Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share. The most efficient and cost-effective time to make fundamental infrastructure decisions is at the design stage, so architects, specifiers, and designers can incorporate security best practices early in the planning and construction process to save time and money while helping plan for future system needs.
