Re: Anyone else notice Bell has Mediaroom now?

The following pictures are just an example of what I see on a regular basis on my PVR unit connected via component cable. I understand this is a rough approach since I am taking a picture with an external camera, but I think it gives a general idea of the issues I am talking about.
The first image is a fairly slow moving scene, and is in my opinion acceptable as an HD image. The second image is a fast moving scene, and lasts approximately 2 seconds. You can see that even the channel labels blur up in this scene. This is from the same show, on the same channel. I just want to know if this is acceptable in terms of HD Picture Quality on the Telus system. |

Vancouver, BC | Well my TV was one of the the first Sony HD sets and is now 5 years old.
I have no problem with Optik TV and movement.Could it be your TV.If not, if it was I, would get a Telus Technician to adjust this for you. |

Don't forget that telus is probably grabbing the OTA feed, which is MPEG2, albeit 19mbps. It's completely possible that the mpeg2 feed had compression artifacts already, and the reencode process amplified that. |

It's a small minority of sources (mainly specialty and foreign channels) that come in MPEG2. Most are transport feeds directly from the provider. If we can get dark fiber, we'll get a baseband feed (HD-SDI) directly over fiber, in locations where that isn't possible, we'll use MPEG4-AVC at over ~20mbps to bring it back to head-end.
In both cases, we are obviously limited by the quality of source content. If there is macro-blocking or heavy pixelization in the source, there is little we can do to make it look good. As the saying goes, shit in, shit out. |
