its not about filesize and more about the bitdepth of the stream and the stability and latency of the link. as a general rule, 30Mb/s (megabit) or so would be a minimum for 720 video. you can stream 720p smoothly over a wirelessG link (max of 54Mb/s). There are many other factors than just network latency, such as the quality of the client video codec, player, and GPU/CPU. the load of the server, its read speed for that disk, and your comms protocol also have an impact. are you having specific issues streaming video from a particular source/protocol? |

Typical 480p/720p low-bitrate profile movie:
Required bandwidth: 0.106MB/s / 108KB/s / 0.8Mbit/s Typical 720p high-bitrate profile movie:
Required bandwidth: 0.676MB/s / 700KB/s / 5.4Mbit/s Typical 1080p movie:
Required bandwidth: 1.44MB/s / 1475KB/s / 11.5Mbit/s However, it seems that wireless connections are less reliable, and the actual transfer speed depends on the stability and latency of the link. These rates apply only for wired connections.
Wired connections are almost always preferred in terms of connection quality. |
