Fine HD Quality Streaming Options for You

Not so long ago, we were approached by a client who is engaged in video broadcasts of auctions and horse races on the air. The events are held in Australia, but the bets on them are made by players in Macao – the game capital of Southeast Asia. Of course, he was faced with the delay of the signal – as without it. The delay is the time between taking a frame and its appearance on the screen of the final device. And if to the usual spectator the delay of 5 or even 10 seconds is not critical, then those who bet on the sweepstake, this difference can cost a lot of money. Hence the problem arose – to minimize the time of passage of video from the source to the viewer. In Demand Africa you will be able to have the best deals.

As a result, the task was solved, it was possible to reduce the delay in the whole chain to 500 ms. We remembered at the same time the case when with the help of our software another client reduced the time of broadcasting the video from Android to the computer screen to 1-2 seconds, which turned out to be the best indicator in comparison with other options that he tried.

We thought that some of the techniques that we applied will be interesting not only to us.

So, the chain of video delivery can be schematically divided into 6 stages: shooting, compression, transmission over the local network from the encoder to the media server, transmission via the Internet, decoding and display on the user’s device.

Let’s see what the costs are determined at each stage and how they can be reduced.

  1. Shooting video

Everything is simple – it all depends on the camera that is used in the shooting. The delay here is less than 1 ms, so when choosing a device, you can focus on the consumer qualities – codecs and protocols, picture quality, price, etc.

  1. Compression (encoding)

Video compression (encoding) is the processing of the original video in order to reduce the size of the transmitted data. The goal is to stream the stream using a suitable codec for the task. Currently, the de-facto standard is the video in H.264 with audio in AAC.

The work at this step affects the whole chain in the future

It is better to give preference to hardware solutions, because Software adds the time needed to work with resources, and the operating system overhead. A correctly tuned encoder does not add any appreciable delay, but it specifies the bitrate of the resulting stream and its type. There are variable bitrate (VBR) and constant bitrate (CBR).

 

The main advantage of VBR is that it produces a stream with the best image quality ratio and the amount of data it occupies. However, it requires more computing power. In addition, if the bitrate at a particular time exceeds the bandwidth of the channel, this will further entail buffering at the decoding stage. Therefore, for real-time video transmission with a low delay, it is recommended to use CBR.

Air conditioners and its installation types

Air conditioners are of different types. They are differentiated on the basis of their efficiency, functions and also on how they are installed. Window units are those air conditioners that are installed in the open window of a building. On the interior, the air will get cooled as the fan blows over it and the exterior [art is where the heat is drawn from the inner side of the building. This air is then dissipated into the outer environment. A packaged terminal air conditioner is the one which is also called as wall split ACs. These types of air conditioners are normally used in hotels and places like that. They do not have any duct that is attached to them. This type of AC is made up of two units which operate separately. The interior portion has the part that is responsible for evaporation and the exterior part is connected to the condenser. There will be an opening in the wall which helps in connecting the two separate units. Mini split ACs are those that can help in cooling one or some rooms of a building. Multi zone systems are those that are made up of ductless systems and can cool up to 8 rooms in a building. This can be done with the help of a single outdoor unit. Central ducted systems are those that can cool a large house as a single unit or are suitable for large commercial spaces. These are only some of the types of Air Conditioners.

More notes on aircon repairs

Air conditioning repair can be done with the help of a good aircon repair Singapore. Most of these service providers are very easily contactable and dispatch for help once they are contacted. But this is not the case always. They also have their peak hours when the service might take hours to reach the destination of the customer. When people read more on aircon servicing, they will definitely know that it is not that difficult to carry out the normal maintenance routines on their own without the help of a qualified professional. It is also important to read more on aircon repair to take care of the urgent situations that might occur all of a sudden. First of all, it is very important to be able to identify the part that has the problem. Only then, anyone will be able to work on it and rectify it.

Clean Room Commissioning

Cleanrooms are used in a wide variety of industries such as Pharmaceutical, Biotech, and Medical Device. Each Cleanroom play critical roles in maintaining contamination free production environments for critical processes. To ensure your cleanroom is working as designed it is essential that a well planned and executed cleanroom testing and certification and maintenance program is undertaken for operation and regulatory compliance. APT cleanroom testing offers clean room testing and clean room commissioning certification.

Clean Room Environment

It is imperative that companies know if any airborne contaminants put products at risk.  It is also very important to understand what the contaminants are, and their origin.  Important environmental measurements, like airborne viable particle measurements, assist with keeping processes in control and with helping to find the root cause of unwanted events such as the ingress of filter pollutants such as microbes, dust, and chemical vapours. With so many hazards to contend with it is essential to monitor cleanrooms for viable particles and other potential contaminants to ensure a clean environment is maintained at all times.

These controlled environments when used in conjunction with the correct protective clothing, equipment, and practices, keep people safe while allowing manufacturing, research, and even medical procedures to be performed consistently and with minimum downtime.

To ensure this consistency, standards have been created by the International Standards Organization. With the implementation of ISO 14664-1: 2015 and ISO 14644-2: 2015 through to 10 as well as ISO14698-1 through 3. These documents outline terminology and measurement units, compliance testing standards, surface and air contamination definitions, and more referenced when undertaking clean room commissioning and validation testing.

Cleanroom Technology

Cleanroom technology has been greatly refined over the last 20 years. Improved HEPA filtration along with HVAC efficiency and construction technology is improving efficiency. HVAC and filtration is especially important in cleanroom design, as the air-change rate ranges help determine a cleanroom’s classification. The ACR is how many times per hour the volume of air in the room is replaced. In a normal home, the ACR is a maximum of 2, but cleanrooms can reach over 700 – the higher ACR the higher the ISO standard for the cleanroom.

According to the latest ISO standards, there are 8 classes of cleanrooms, with different standards required for various applications. Each of the eight ISO classes is determined by how much particulate of specific sizes exist per cubic meter.

Required Testing (ISO 14644-1)

The corresponding ISO standards necessary for each particular class of cleanroom should remain consistent across all equipment to ensure full protection. Without ISO adherence, contamination can cause equipment breakdown and quality degradation.  Considering most cleanrooms are a company’s main critical it is essential that they are maintained in-line with relevant ISO standard.

Each classification also has different testing requirements to ensure standards are being met. The following chart lists mandatory tests and frequency to maintain ISO compliance

In addition to the Particulate Count Testing and HEPA filter testing you can also undertake containment leakage, recovery, and airflow visualisation. These additional tests aren’t required for compliance but can help proactively maintain a cleanroom environment, especially in high-risk environments with stringent ISO standards.
