How much bandwidth do you need ?

It’s essential to have sufficient bandwidth to have an optimal streaming experience. So, let’s dig into the bandwidth requirements for different resolutions and streaming services.

Understanding Video Bitrate

Video bitrate is an important metric independent of other factors like resolution, frame rate, and audio quality that impact a viewer’s streaming experience. It represents the amount of data per second your video source supplies and is a critical factor in delivering an enjoyable experience.

Streaming Services and Bitrate

It’s interesting to note that compared to a Blu-ray disc, streaming services like Netflix need to use compressed streams with considerably lower bitrates. Despite their best efforts to maintain the quality through various compression techniques, a higher bitrate equals more data and a superior image quality.

Minimum Bandwidth Required

To sustain a smooth, buffer-free stream at varying resolutions, one should consider these average minimum bandwidth requirements. Whether you’re using older equipment or new streaming devices with the latest TV models, Broadcasters generally provide viewers with the best possible streaming experience.

Following is the general resolution for videos and Minimum download speeds required:

480p (SD):  Needs about 3-4 Mbps

720p (HD):  Needs about 5-8 Mbps

1080p (HD):  Needs about 8-10 Mbps

2160p (4K):  Needs about 32 Mbps

4320p (8K): Needs about 120 Mbps

Required Bandwidth

H264 H265

1280×720(HD) 3Mbps 1.5Mbps

1920X1080(FHD) 6Mbps 3Mbps

3840×2160(UHD) 25Mbps 12Mbps

3820x2160p(4K) 32Mbps 15Mbps

7640×4320(8K) See notes below

1080p Streaming required Bandwidth & Internet Speed

1080p streaming videos are at a display resolution of 1920X1080, and it offers full HD video content on the Internet. These videos have more clarity and resolution than an HD video at 720p. Also, 1080p video consumes more amounts of data compared to SD and HD streaming. As stated in the above table and with the H264 codec, the recommended bandwidth is 6 Mbps, and with the H265 codec, it usually requires up to 3 Mbps.

4K and 8K Streaming Bandwidth requirement / Internet Speed

To stream 4K HDR content, one needs a 4K UHD TV with HEVC decoder and HDR support. 

4K videos with a display resolution of 4096p x 2160p offer the most life-like video content on the Internet. These high definition videos have more visual information than ever about the texture, color, shapes than an HD video. Unfortunately, 4k consumes enormous amounts of data compared to SD, HD & FHD streaming. With the H264 codec, the recommended bandwidth is 32 Mbps, and with the H265 codec, it could be up to 15 Mbps. To stream 4K HDR content, one needs a 4K UHD TV with HEVC decoder and HDR support.

Even with an 8K streaming service, most people wouldn’t be able to use it. Platforms like Netflix specifies a 25 Mbps stream for 4K content. This requirement seems to quadruple as there is no H.265 standard alongside 8K to reduce the file size. Netflix consumes 3.1GB/hour at 1080p for 60fps video and even 7GB/hour at 4K. If we assume that the transition from 4K to 8K consumes an equivalent amount of bandwidth to 1080p – 4K transition, the per hour bandwidth requirement to stream 8K content would be nearly 6.44GB – 19.2GB/hour for 23.976fps content. This is still a high bandwidth rate to burn out.

The bitrate for 8K video services that use HEVC is between 85 Mbps for satellite and 65 Mbps for OTT. 

When you implement Content Aware Encoding (CAE) used in combination with HEVC, you can lower the bit rate for 8K distribution by another 50%. CAE leverages the mechanics of the human eye to assess video quality and optimize encoding parameters in real-time.

Video Production Tips: Pain Points & Solutions – What are your Suggestions?

Video production involves several stages, each with its unique set of challenges. Some common pain points in video production are:

1. Pre-production planning: To avoid delays, budget overruns, and scope creep, video production teams should establish clear goals and objectives, outline the desired outcome, and develop a detailed production plan that aligns with the production budget and scope. Project management software can help manage tasks, set deadlines, and monitor progress, while regular meetings and status reports can keep everyone on the same page.

2. Equipment-related issues: To prevent equipment failures or inadequacies, video production teams should invest in quality equipment, perform regular maintenance and testing, and have backup equipment on hand. Additionally, having a skilled technician on the team or on call can quickly resolve equipment-related issues and reduce downtime.

3. Creative and technical collaboration: Video production teams can improve creative and technical collaboration by establishing clear communication channels and processes, involving everyone in the brainstorming phase, and setting realistic expectations about the project’s technical feasibility. One solution is to use a review and approval platform that collects feedback and changes from all team members and keeps everyone informed about progress.

4. Time constraints: To manage tight video production timelines, video production teams should prioritize tasks, establish clear timelines with deadlines, and allow for some flexibility. Outsourcing some tasks or using pre-made templates and resources can also save time and reduce workload.

5. Post-production challenges: To avoid post-production delays, video production teams should establish a clear post-production plan, including deadlines, resources needed, and project milestones. Collaborating with a post-production specialist or outsourcing some post-production tasks can also help manage the workload and free up resources and time.

6. Delivery and distribution: To ensure a smooth delivery and distribution process, video production teams should carefully consider the delivery platform and format and create multiple versions for different devices and platforms. Using cloud storage platforms can make sharing and delivering large files easier.

7. Budget and finances: To stay within the allocated budget, video production teams should create a detailed budget plan, track expenses, and prioritize expenses according to project needs. Being transparent about the budget and communicating any potential expenses can reduce surprises and avoid overruns.

Why We Care: PTP Clocks Hierarchy

PTP (Precision Time Protocol) is a protocol used for synchronizing clocks in a network. It is a time synchronization protocol that is designed to provide high-precision time and frequency synchronization for networked devices.

PTP (Precision Time Protocol) is an IEEE 1588 standard protocol that synchronizes real-time clocks of connected nodes in a distributed system using a network. This protocol establishes a leader-follower hierarchy among the nodes (referred to as clocks) where followers synchronize with their leaders, and the leader-follower relationship is determined by a Best Master Clock (BMC) algorithm. Through dynamic relationship determination, the PTP network can simplify the interconnect graph, resolving cycles down to a tree of leaders and followers. The grandmaster, located at the root of the tree, synchronizes with GPS and serves as the ultimate leader for all clocks. Interior nodes in this network are called boundary clocks (BC) and have follower ports and one or more leader ports. PTP can achieve high accuracy, even within sub-microsecond limits on local networks.

PTP works by sending time signals between devices, a best grandmaster, leader, and a follower clocks. The best grandmaster clock sends synchronization messages to leader clocks, and the leader clocks adjust their clock frequency and time to match the best grandmaster clock. The leader clocks send synchronization messages over their network(s), and the follower clocks adjusts their clock frequency and time to match the leader clock. Again, aka boundary clocks. PTP uses precise hardware timestamps to measure the time between devices.

PTP is often used in real-time systems, where accurate timing is essential, such as in audio and video production or industrial automation. It can also be used in some communication networks, such as 5G and industrial Ethernet.

Quick Reference: CDNs

A CDN (Content Delivery Network) is a geographically distributed network of servers that helps deliver content (such as web pages, images, videos, etc.) to users from servers that are geographically closer to them, resulting in faster page load times and better user experience.

A CDN typically works by storing cached copies of a website’s content on multiple servers distributed across different geographic locations, called edge servers. When a user requests content from the website, the CDN automatically redirects the request to the server that is geographically closest to the user, reducing latency and minimizing network congestion. The CDN also helps to distribute network load and protect against Distributed Denial of Service (DDoS) attacks, among other benefits.

Edge servers are a key component of CDN architecture. They are small-scale data centers that are strategically placed in multiple distributed locations around the world, as close to end-users as possible. 

When a user requests content from a website, the nearest edge server to the user intercepts the request and serves the cached content that exists on that edge server itself. If the content is not available, the edge server pulls it from the origin server, caches it locally, and then serves it to the requesting user.

Edge servers are designed to handle high traffic loads and to deliver content with low latency and minimal network congestion. They help improve the performance and reliability of websites by reducing the distance that data needs to travel, and by distributing network load across multiple servers.

25 CDN companies and what broadcasters generally use them for:

  1. Akamai – Used for live streaming, software downloads and website optimization.

9 Tips for Women in Business

1. Prioritize self-care: Make your physical and mental health a priority. Prioritizing self-care habits such as getting enough sleep, exercising regularly, seeking support from friends and family, and managing stress can help prevent burnout and increase productivity.

2. Have SMART (Specific, Measurable, Attainable, Realistic, Time-Based) goals for your careers and put systems in place to achieve them. By identifying achievable goals and breaking them into smaller, more manageable steps, women can avoid the feeling of being overwhelmed and stay motivated.

3. Learn to delegate: Delegating tasks to other team members, including household tasks, this can create more time and energy for your careers and reduce burnout.

4. Build a support system: Networking and building a support system of like-minded women can be beneficial for navigating challenges and responsibilities that come with a demanding career.

5. Practice time management: Effective time management can help juggle both work and personal obligations. Prioritizing tasks and setting boundaries for how much time and energy to allocate to specific tasks can help be effective.

6. Use technology to your advantage: Technology can be a useful tool to manage tasks, team communication and efficient work processes which can help maximize time and reduce stress.

7. Seek flexibility: Create a job that is flexible or allows for remote work arrangements. This can help create more work-life balance by eliminating long commutes and taking charge of schedules that may not work as per their needs.

8. Take breaks: Taking regular breaks throughout the day, and in life in general, can help you recharge and return to tasks with a renewed focus and energy.

9. Not sure about achieving your goals? Develop a Why Not? attitude. Don’t give yourself excuses of why you can’t achieve your goal. Don’t look at the barriers or how “something has always been done”, don’t be afraid to challenge the norms, find out about a company you can help, and the solutions you can provide. Why Can You Do It? Keep an open-mind.

Broadcasting Tips: QC’ing and Transcoding files

In media production, building QC (quality check) and transcode files for use in manual and automated workflows typically involves the following steps:

1. Determine the specifications: Identify the technical requirements for the media file based on the delivery platform or distribution channels. This includes file format, resolution, aspect ratio, bit rate, frame rate, audio format, and other technical parameters.

2. Encode or transcode: Once the file specifications are defined, use a transcoding software to encode or transcode the media file to the desired specifications. This process converts the file from its original format to the required delivery format. Ensure the output quality is up to the expected standards.

• Note: Encoding and transcoding are both processes of converting digital media files from one format to another. However, there is a distinction between these two processes that is important to understand.

Encoding refers to the process of compressing digital media files into a specific format to reduce file size while retaining as much quality as possible. This compression can be lossless or lossy, depending on the encoding method used.

Transcoding, on the other hand, involves taking an already compressed media file and re-compressing it into a different format or bitrate. This can involve changing the media file’s resolution, aspect ratio, frame rate or other technical parameters.

While both encoding and transcoding can be used to reduce file sizes, encoding typically involves compressing high-quality files for use in delivery platforms while transcoding focuses more on adapting existing media files to suit a variety of distribution and delivery platforms.

The main difference lies in the fact that encoding is the process of compressing an un-compressed file for storage or streaming purposes, while transcoding is the process of converting an already compressed file into a different format, resolution, and/or bit rate.

3. QC check: Once the file is transcoded, it must be tested to ensure it meets technical specifications and quality levels. This can be done manually or through an automated quality control system that checks for technical issues such as pixelation, color accuracy, brightness, and resolution.

To specifically test QC’d video and ensure it meets technical specifications and quality levels, you can follow these steps:

• Check the video resolution: Ensure the video resolution matches the intended output specifications. For instance, if the video is meant for a 1080p output, verify that the resolution is 1920×1080.

• Verify aspect ratio: Verify if the aspect ratio of the video is correct. This can typically be set to 16:9 or 4:3.

• Check bit rate: Verify that the video’s bit rate meets specified requirements. This will affect the video quality, and too high or too low bit rates can result in poor quality.

• Test audio quality: Check audio levels, clarity, and timing. Ensure audio levels don’t clip or distort, and that the audio is synced correctly to the video.

• Check color and exposure: Verify the color accuracy and exposure levels of the video. Ensure that the colors are not too saturated or de-saturated and that the exposure levels are not too bright or too dark.

• Run tests for technical issues: Quality control software can automate this step by running a series of automated tests to check for technical issues. Some common issues software can detect include pixelation, interlacing, dropouts, and compression errors.

Here are ten series of automated tests that are commonly used to check for technical issues in the broadcast media industry’s QC process:

– Video signal analysis: This involves analyzing the video signal to detect issues such as missing or duplicate frames, video compression artifacts, and signal dropout.

– Audio level analysis: This involves analyzing the audio levels to verify that they are within acceptable levels and that there are no audio dropouts.

– Lip sync analysis: This test checks that the audio and video are in sync with each other, with no noticeable delays or desyncs.

– Closed captioning analysis: This involves analyzing the closed caption data to ensure that they are synced correctly with the audio and video.

– Loudness compliance analysis: This test ensures that audio levels comply with relevant loudness guidelines, such as CALM Act.

– Video quality metrics: This measures various video quality metrics, such as Peak Signal-to-Noise ratio (PSNR), Structural Similarity (SSIM) and Mean Opinion Scores (MOS), to ensure that the video is of high quality.

– Aspect ratio and resolution compliance: This test ensures that the video’s aspect ratio and resolution comply with relevant specifications.

– Subtitle and caption compliance: This verifies that subtitles and captions adhere to standards and are free from errors.

– Compression analysis: This test checks that the video encoding and compression have been applied correctly, and verifies that bitrates aren’t too high or low.

– Color and gamma analysis: This test verifies correct color space and level and image brightness or dark values through gamma analysis. 

These automated tests help ensure that broadcast media content is delivered to its intended specifications, and adheres to industry standards for technical quality.

– Check for legal compliance: Verify that the video does not contain any copyright infringements or other legal compliance issues.

4. Review and revise: Once QC checks are complete, review the results and revise any errors or issues that were found. This can involve making additional cuts, color correction, or other adjustments.

5. File-naming convention and metadata: Consistent file naming convention and metadata is essential to ensure the media assets are managed and distributed optimally. Using a bespoke asset management system or media production software that tag and track the files and the corresponding metadata allows for efficient and accurate searching and retrieval for the use of the assets in future projects.

By following these steps, media producers can ensure that their assets are optimized for different platforms and workflows while also making sure that the files meet the required technical standards for delivery.
