What To Know About Bitstream
Bitstreams are responsible for ensuring that all types of digital data get where they need to go. However, not many people know how these data streams work. Learning about them could help you see where your current setup needs improvements.
In this article, we’ll explain how bitstreams work across different industries and how to manage them properly.
What Is Bitstream?
A bitstream is a series of binary digits that a system transmits as a continuous data stream. Any industry that relies on data processing or digital communication depends on bitstreams.
Bitstreams show data entirely as ones and zeroes. They can encode any form of information, up to and including text, video, and audio. When you listen to music, you’ll likely use a bitstream.
In an audio context, bitstreams turn sounds into bits and send them to a receiver. You’ll hear the “decoded” version. Both PCM and HD audio rely on bitstreams. Here are just a few reasons why these technologies need bitstreams to work well:
- Flexibility: Because bitstreams are digital, they’re far easier to edit.
- Efficiency: Bitstream transmissions save bandwidth by compressing data.
- Consistency: The end result will closely match the original audio.
- Broad support: Bitstreams generally support many modern codecs.
How Do Bitstreams Work?
Bitstreams work differently across every industry, though the key principles stay the same. From transmitting communications to streaming video, your system’s backend will follow roughly the same steps. These are as follows:
1. Encoding
The system encodes and compresses audio and video data. Depending on the application, your system might apply special encoding techniques. For example, non-return-to-zero encoding will maintain distinct voltage levels to interpret data more efficiently.
2. Transmission
Your system then transmits the data over a communication channel, such as Wi-Fi or fiber optic cables. The bitstream will be serial (one bit at a time) or parallel (many bits at once).
3. Synchronization
At this stage, the data arrives at the receiver. A clock signal helps it figure out every bit’s precise timing. Without seamless synchronization, files will face corruption or other minor glitches, such as lip sync issues.
4. Decoding
Once the receiver has synchronized the data, it’ll start decoding everything. The bitstream then becomes a series of frames or samples. Your device will interpret these as a complete audio or video file.
Which Industries Use Bitstreaming Solutions?
Bitstreams are highly effective at transmitting and processing data. This makes them vital in many industries. Here are eight sectors that rely on bitstreams:
- Telecom: VoIP and video call systems use bitstreams to connect their users. They transmit speech in real-time, and usually without a noticeable quality loss.
- Streaming video: Online video platforms such as YouTube and Netflix use bitstreams to share content. These use special encoding formats such as MPEG or MP3.
- Electronics: Bitstreams are vital for updating or configuring electronics. For example, an FPGA circuit uses bitstreams to assess logic, routing, and memory values.
- Cloud computing: These systems stream and store data with bitstreams. If you’ve ever uploaded a file to the cloud, bitstreams made this possible.
- Aerospace: Aircraft should be in constant communication to safely fly in the same skies. Bitstreams help air traffic controllers coordinate this via real-time telemetry.
- Healthcare: Medical imaging generates high volumes of data. Bitstreams let a hospital’s systems manage this data flow while developing a clear and accurate image.
- Gaming: Video game consoles process a game’s code, textures, and more to create an impressive 3D world. Bitstreams also help developers update their games.
- Defense: The defense industry relies on bitstreams for encrypted communication. It also uses them to transmit control signals to drones and even guided weapons.
What Kind of Equipment Do You Need for Bitstream Management?
As with any form of data transmission, you’ll need special equipment to manage bitstreams. For example, PCs and data servers will encode and process the streams themselves. You’ll also need networking equipment (such as routers and modems) to transmit or receive streams.
In addition, hard disk drives or solid-state drives could help you store large volumes of data. The latter, in particular, boasts faster read and write speeds.
To accurately decode the bitstream’s files, you’ll need a specialized player. For example, a video player should be able to accommodate a file’s H.265 codec.
Digital signal processing chips are another key component of bitstream setups. They compress the original file by implementing space-saving codecs. For audio, this includes MP3 and AAC.
Bitstreams in AV Technology: What To Pay Attention to When Using Them
You can only make the most of bitstreams with the right tools and tips. Here are eight essential considerations to bear in mind when working with bitstreams:
- Format support: The source and receiving devices must support the right formats. Not every set of speakers has Dolby Atmos, for example.
- Hardware compatibility: Similarly, make sure your tools can handle intense bitstreams. For example, HDMI 2.1 tech has a higher bandwidth.
- Connection type: Your connection type will also affect your bitstream. HDMI is better for lossless audio, which optical cables can’t use.
- Bitrate: Your bitrate is how much data the bitstream handles. A bitrate that’s too high will lead to an unnecessarily complex (and possibly corrupted) bitstream.
- Codec support: Audiovisual media relies on codecs for encoding and decoding. Your system or device must support modern codecs, such as AV1.
- Bandwidth: HD audio or video will naturally require more bandwidth to transfer. Ensure your tech has high-speed data transfer features.
- Updates: If you run into an issue, the first step is to update your firmware. Alternatively, you can switch to another provider with fewer bugs.
- Future-proofing: Consider investing in new AV equipment. These can handle a greater range of codecs and formats and last much longer.
Final Thoughts
Bitstreams are fundamental for any digital data transmission. They act as a universal language, one that virtually any new device can interpret. So long as you use modern technology, you can easily decode bitstreams.
If necessary, you should consider investing in new audiovisual equipment. Upgrading your setup might be the only way to find support for modern video or audio codecs.
