Explain compressed domain preprocessing for inserting forensic watermark in a video asset

Watermark generation, which is also called watermark preprocessing, randomly scrambles watermark information in a video asset to enhance the security of the watermarking algorithm. Watermarking in the compressed domain is often preferred over watermarking in the spatial domain since decompressing and then recompressing the entire video data might not always be feasible due to high storage capacity requirements. Reencoding an MPEG stream also significantly increases the processing time, sometimes even rendering it unsuitable for real-time applications where embedding processes go parallel to compression.

However, some constraints in compressed-domain video watermarking are the increase in computational complexity and restriction in the amount of watermarking information (going beyond the capacity of watermarking information might enhance the bit-rate of the watermarked video). Hence, watermarking schemes are implemented during the compression of video by partially modifying the structure of compression standards, such as MPEG-2, MPEG-4, AVC (Advanced Video Coding)/H.264, HEVC (High Efficiency Video Coding)/H.265, etc.

MPEG is a compression scheme for standard digital television and high-definition TV, and has a coding rate ranging from 3 Mbit/s to 100 Mbit/s. MPEG-2 program streams and MPEG-1 system streams are multiplexed streams containing at least two elementary streams, i.e., an audio and a video elementary stream. An efficient watermarking scheme should be able to deal with multiple streams, which is the primary requirement in an OTT environment which pushes DRM protected content. Typically, the original stream is demultiplexed into the constituent elementary audio and video streams which are then processed to embed the watermark. The watermarked elementary streams are then multiplexed again to produce the final MPEG stream. However, this method has a high computational cost and complexity. Hence, many watermarking algorithms in the compressed domain only perform partial decoding in the embedding process and deal with the multiplexed stream itself.

H.264, which is also the 10th part of MPEG-4, is a highly compressed digital video codec standard that has a higher data compression ratio and video picture quality. Most robust watermarking schemes based on AVC/H.264 embed watermarks into DCT coefficients. H.265 is the successor of H.264 and has a better compression performance. It can transmit higher quality network video with limited bandwidth, and only needs half of the original bandwidth to play a video with the same quality.

How to drive traffic to your ecommerce store

A good email list can boost your revenue with a good email marketing strategy by driving traffic to your store. Either if you decide to reach out to an Ecommerce Email Marketing Agency or do it inhouse you should consider some basic points that will help you increase your website traffic and eventually convert.

The content you send should talk about your products/services, process of production, brand mission and philosophy and what works the most is How to and Tips & Advice Newsletters that are connected to your main products or collections.

  1. Use visually appealing Templates

Make sure you’re using attractive layouts for your email campaigns so that your subscribers are driven to click, go to your website and eventually convert. If you don’t feel inspired here are some Great Email Templates for Email Marketing that will help you get some nice ideas to engage your list.

  1. Don’t give everything in the email

Even though we want to offer good content to hook our subscribers we don’t want to give them the whole information in our Newsletters so make sure you just give a hint of what they can find in your site. One great advice is to have a blog in your ecommerce store where you can drive them to when you talk about specific subjects.

  1. User friendly website

The journey doesn’t end once they’ve clicked on your email. Since our main goal is to convert, make sure your website is easy to navigate and user friendly, this way you’ll manage to avoid high bounce rates that might affect your site performance and analytics.

  1. Offers & Promotions that hook your customers

For big holiday campaigns make sure that you’re using attractive offers that catch their attention and make them click. Remember that once they are navigating in your website the information should also be displayed, discounts applied and all the FAQs responded. This way we increase the probability of conversions and address any kind of doubts or fears they might have.

Advertising is not the only way to drive traffic to your website, there’s also other channels to do it and Email is one of them, don’t underestimate this media that beyond disappearing – as much would say – is still growing and helping us overcome challenges such as the new iOS and Google privacy updates.

Moving Overseas When You Have Kids

A move overseas can be a big enough decision, but when you have kids, it can be even more difficult. Kids are sometimes resistant to the idea of moving abroad, and you may find that you need to ensure they keep the same sort of lifestyle when they move, so they don’t feel alienated. If you’re considering a move abroad with children and aren’t sure where to start, follow the tips below.

Get them prepared for the move

Preparation is key when it comes to a big move. You can do this by:

  • Talking to them about the move well in advance
  • Letting them research your destination and find things they’ll like
  • Making sure they know they can stay in touch with family and friends
  • Making sure they pack sentimental items, so they have them when they arrive

Kids are usually adaptable and able to cope with change, but it’s important to get them prepared.

Choose the right school

The right school can also help them to settle in, and means their education isn’t disrupted. You may want to consider Thailand Bangkok international school, as they can still get lessons given in English, while also learning the local language at their own pace. International schools can also be excellent for expat kids, as they have their own community, and your child is more likely to make friends when they arrive.

You can have a better work life balance

One of the reasons many people become expats is because some countries have a more family-focused culture. This can mean a better work/life balance, where you spend less time at the office and more time with your kids. If you can achieve this, then your child may be happier moving abroad, as they’ll enjoy a much better lifestyle. Before you leave, research where you are going and look into what’s around the area. You can then plan some amazing family days out with your kids and enjoy great family time together.

If you’re thinking of moving overseas, having children shouldn’t stop you from doing so. But you will need to put extra plans in place for them. Children can sometimes be upset by the thought of moving abroad, but it can be a big boost for your family and can give you more time to enjoy together. While your child may be resistant at first, over time, you’ll find they settle into a new pace of life.
