Scalable Streaming Technologies

Streaming TechnologyBy

In today’s modern world it is imperative that video can be handled in many different ways. The transportation of video from one location to another has become critical in delivering the services that are required for professional AV projects. From real time remote access of surveillance cameras to the distribution of video content and recording & storing of data for later retrieval, the needs of the markets demand technologies that meet these requirements.

Datapath’s range of SQX technologies gives customers the power to handle video to meet the

needs of the Professional AV market. At the heart of SQX is the ability to take video and encode it

for streaming or remote storage and to decode compressed data for use on a video wall or

monitor. The Datapath SQX technology portfolio offers a series of products that can either work

alone or as part of a much wider system to manage a vast amount of video in ways customers

require.

INTRODUCING DATAPATH SQX TECHNOLOGIES

Scalable Streaming TechnologiesSQX is Datapath’s collective name for video streaming & compression technologies. Datapath’s

SQX products open up a world of possibilities for video delivery, transmission and storage whilst

maintaining the ability to easily scale projects from the management of a single stream to full

inclusive systems that accommodate a wide array of inputs and outputs streaming from a variety of

sources to a number of destinations.

SQX decoding technology can uncompress encoded media for viewing locally on a video wall.

The SQX decoding capabilities include the SoftSQX application, where the core system processor

receives and decodes the IP stream and PCIe card based ActiveSQX which includes a dedicated

processor which can work alongside additional SQX cards, in the same system, to provide

scalability and a huge number of simultaneous decodes under a single operations platforms. Once

decoded video can be passed to a graphics card (such as the ImageDP4) for display on a video

wall, allowing video captured and streamed from New York can be received in London and spread

across many screens.

The SQX family of technologies provide the ability to capture several channels of high quality,

high bandwidth video simultaneously and encode each of them before providing the user with the

choice of final destination, whether that is streaming on-line for viewing elsewhere, storage to

network video recorders for archiving or saving to a local disk for future access.

Datapath’s SQX encoding cards are capable of compressing up to 1920x1200 video at 60 frames per

second or two 1920x1200 videos at 30fps using the global H.264 standard. This is achieved through

the use of a dedicated on board processor. Synchronisation is maintained across multiple cards

and inputs by way of hardware time stamps allowing two or more streams to be accurately frame

matched once viewed.

Once combined with Datapath’s MultiStream technology, multiple instances of the encoded data

can be used independently.

H.264 H.264 is the de-facto standard in video compression and streaming. Used by CCTV equipment manufacturers, streaming

media companies and broadcast markets, H.264 provides a globally accepted standard for video compression. SQX has been

designed to work with H.264 compression and allows customers to interact with video from a wide range of sources.

H.264 encompasses a number of profiles. SQX technology supports the following profiles:

• Baseline Profile: Commonly used in video conferencing systems

• Main Profile: As used in Digital TV broadcasting

• High Profile : Critical for High Definition applications and storing to disk

VisionHD2-SQX

ActiveSQX

SoftSQX

The VisionHD2-SQX is a triple channel capture and encoding

device for a Windows based operating platform. Capture two HD

1920x1200 videos and encode them directly into H.264. Each

encoded video can be streamed via our media server or shared

to a disk. The VisionHD2-SQX is capable of two simultaneous

1920x1200 30fps encodes or a single 1920x1200 60fps encode.

Supporting PCIe technology multiple VisionHD2-SQX cards can

be used in a single system offering flexibility and scalability.

Additionally captured video can be transferred directly to a

graphics card for display.

Datapath’s ActiveSQX is a powerful PCIe card designed to decode

multiple streaming videos using an on-board processor. Multiple

ActiveSQX cards can be used in a single system to support the

management of entire CCTV systems or connect to online media

libraries, streaming and decoding video for immediate video wall

display.

SoftSQX is part of Datapath’s Wall Control SQX application. Designed for new and existing systems that may require the

management of a fixed number of compressed streams. Used as part of a Datapath WallControl SQX, SoftSQX uses the

system processor to decode streams. Datapath PCIe technology allows video to be captured and displayed on a video wall

without the system processor being involved, this leaves valuable system resources free for decoding. SoftSQX uses these

resources and can decode approximately 12 x 1080p 30fps streams, dependent on the underlying CPU.
