Why is video always buffering on my iPhone 4?

Episode 1214

Joe from Florida

Joe is frustrated because video is constantly buffering on his phone. Leo says it could be the phone. Older hardware has to work harder to play hi-res video. But more likely, it's Joe's carrier, which can have limited bandwidth. Since Joe is using Sprint, they've been late in coming to the LTE party, and it may be that LTE isn't available in Joe's area. An older phone, like an iPhone 4, won't even support LTE. A new phone will help, but Joe should make sure LTE is supported in his area.

How can I stop my video from buffering?

Jim from Los Angeles, CA

Jim is frustrated because he'll be watching a video on his phone and it'll buffer. Leo says that's a speed/bandwidth issue. Streaming will buffer about 30 seconds of video before starting to get ahead. Then if the packets come out of order or slow down, the buffer is there. If it happens a lot, the buffer will just run out and rebuffer. So it has to do with connection, bandwidth, and the ability of your system to keep up. Faster internet will solve the problem, as will a lower resolution stream.

FCC Promises to Investigate ISP's Buffering

Episode 1092

If you're a Netflix customer using Verizon FiOS or DSL, you may have noticed a message being displayed when video streaming slows down. The message blames Verizon's network congestion for the video buffering. Netflix has been confirming that the issue is with Verizon by checking with other Verizon customers. Verizon sent Netflix a cease and desist letter saying that if they don't stop doing this, they will sue.

Why does my video stream buffer so much?

Kathy from Santa Clara, CA

Kathy watches Leo online through UStream and is frustrated because it buffers a lot. Leo says it's on UStream's end, and he can't do much about it. He also streams through BitGravity and Justin.TV, so she could try one of those. Also, choosing the lower resolution from BitGravity could help. Kathy should also look at her bandwidth online. If she only has 1.5 Mbps down, for instance, she will continue to have a rough time with streaming. It could also be a bad modem. She should ask for a new modem or buy her own. She could first try rebooting both the modem and router.

John from Kendrick, WA

John says that when he watches video online, it buffers and the quality devolves a lot. Leo says it's amazing how we expect streaming video to have the quality of television now. And often it is. But data doesn't arrive in order and on time like a broadcast signal is. It's transmitted in packets and sometimes those packets arrive out of order, and has to wait for the missing packets to be received in order to play them back. If it doesn't arrive, then it stutters to the next available packet. The computer John is using may not be fast enough, though.
