To avoid buffering while streaming, you can follow these four methods:
- Limit connections: Even if your router is relatively new, it may not have the capacity to be fully powerful.
- Fill the cache: Some data is temporarily saved every time you access the internet.
- Use an Ethernet cable.
- Disable hardware acceleration.
Streaming Time and Data Usage
People often ask how much time is needed for streaming on Twitch. Typically, connection speeds are expressed in Mb/s or Gb/s, while the amount of data is expressed in Mb/s or Gb/s. For streaming a 1080p60 video on Twitch, you need 6Mb/s, which is equivalent to 0.75 MB/s. Therefore, it consumes 0.75 MegaBytes (MB) of data per second. Another common question is how many GB is used for streaming. Here’s the answer:
- Low: up to 0.3 GB per hour per device.
- Average: up to 0.7 GB per minute per device.
- High: up to 3 GB per hour in HD; up to 7 GB per hour per device in Ultra HD.
Streaming adjusts automatically to internet connection speeds to ensure the best possible quality.
Bitrate and ADSL
Bitrate refers to the amount of digital data that can be transmitted over a communication channel in a specific time interval during a connection or transmission.
The maximum upstream bitrate for ADSL is ITU G.992.4 ADSL2 (G.bis.lite) with a speed of 1 Mbit/s in ITU G.992.Appendix JADSL 23.5 Mbit/s ITU G.992.4. LRE-ADSL Annex 21.2 Mbit/s ITU G.992.
After reaching 5 ADSL2+1 Mbit/s, the Universal Service Law requires internet connections to have a minimum bandwidth of 30 kbit/s and voice service.
Streaming 1080p
For HD 1080p video streaming, the upload/download speed is 1.8 Mbps. The quality of ultra HD images requires a minimum network speed of 7 Mb/s. However, some streaming services may require ultra-fast connections of 25 Mb/s. On average, active streaming services in Italy have a network speed of 19.31 Mb/s and work well.
To adjust audio on OBS, follow these steps:
- Select the "Settings" section of the software.
- Click on the "Output" tab.
- Set appropriate bitrates for video and audio, ensuring that the total sum of video and audio bitrates never exceeds the limit of your plan.
