Was I having a stroke on Monday night, or was the MNF HD broadcast a
disaster? The picture kept switching from a "normal" HD broadcast to a blurry mess whenever the HD SkyCam was used, and randomly throughout normal camera transitions. Not only was the game blurry, but - and this I just don't understand - the GRAPHICS were blurry too. I was watching OTA, so I called a friend with Comcast in HD, and he said he was seeing the same thing - on both the local affiliate (6 ABC) *and* on ESPNHD. Did anyone else see this? What caused this? Bad truck? ~ Zymer |

The local ABC affiliates in local markets have broadcast rights to MNF
games and soon, the NFL channel games on Thursdays. Do you have an opinion about the picture quality, Larry?

Clearly you were having a stroke, since MNF is not broadcast on ABC anymore, so how your friend was seeing the "same thing" on ABC is beyond me. |

Larry,
I'm the friend who WAS watching on ABC. Comcast Delaware County carried the broadcast simultaneously on ABC and ESPN. It was of equally bad quality on both. Is THAT beyond you? |

Is THAT beyond you? I was watching it on ESPN here in NY with Cablevision and I thought it looked great. Maybe it was a local problem? Thanks Mike. I really appreciate the input. Were you watching in hi-def? (Yes, I realize we're in the HD group here, but I want to be sure we're all on the same page...) If it was a *local* problem, then either Comcast in Philly would need to get the feed through the ABC affiliate (O&O by ABC/Disney company) or the other way around... Maybe CC was getting a bad feed and feeding it to the local ABC station? That would *seem* to be plausible, but if that were the case, then why did the signal deteriorate for 5 seconds or so when the MNF producers switched between cameras? That makes no sense to me. Here's a related article on TVPREDICTIONS which calims the ESPNHD signal was better: http://www.tvpredictions.com/whipgame100406.htm Commentary Can Multicasting Hurt HDTV Picture? By Joseph Whip HD Observer Editor's Note: Many high-def owners are concerned that a local station's HD signal can be diluted if that station broadcasts additional digital feeds at the same time. This is known as multicasting. Here's one reader's take on the subject. Philadelphia, PA (October 4, 2006) -- The effects of multicasting on a broadcaster's primary video signal was well in evidence Monday night during the Eagles-Packers Monday Night Football game on ESPN HD. The game was simulcast on the ABC affiliate in Philadelphia, WPVI. We therefore had a chance to compare the full bit rate ESPN HD feed and a bit rate starved HD feed on WPVI which has two subchannels (additional digital channels). The results were not pretty. While the broadcast was not one of ESPN's best efforts, its picture was sharp and detailed compared to the over the air telecast on WPVI. This was the case whether watching both on Comcast cable and comparing the ESPNHD feed to an over the air feed on WPVI. The WPVI feed was blurry in comparison and out of focus. It was like trying to watch the game through a haze. As usual, the engineering department at WPVI, when contacted about this, blamed the setting on their encoder. I have seen the effects of a Harris encoder set to adaptive as was the case last night vs. one that was set to fixed and this was not the problem last night. The problem last night was continual. They also claimed that Comcast does not allocate enough bits to their broadcast and favors ESPN even though they are both owned by Disney. This is simply an excuse and one that does not hold water given the poor quality of the over the air broadcast compared to ESPN HD and given the high quality of the other HD broadcast signals on Comcast.. Clearly, the over the air broadcast was bit starved. One would have expected that WPVI (and ABC) would have wanted the game to have looked its best for those in the Philly market without cable. They did not and failed to properly serve the needs of their viewers. Why not simply turn off the subchannels during a significant HD event in the market? Why ruin a broadcast by running an infomercial channel and a weather channel of poor picture quality? Of all the HD sets in the Philly market last night, just how many do you think were turned into the WPVI Accuweather channel instead of the Eagles game? I can't imagine there were any! WPVI, please turn off the subchannels the next time the Eagles are on Monday Night Football and consider turning them off during any HD broadcast as well! |

Thanks Mike. I really appreciate the input. Were you watching in hi-def? (Yes, I realize we're in the HD group here, but I want to be sure we're all on the same page...) Yep it was HD. |

The ABC affiliate was broadcasting the ESPN feed whole-cloth. Same
everything. I sent a TVPredictions analyst in the Philly area this e-mail: My first question is, when I was watching the OTA feed why would the picture (and graphics package) suddenly go blurry SPECIFICALLY on certain cameras, like the SkyCam shots, if it was a merely a transmission problem? - That would seem to me to be a SOURCE-related problem, not a re-broadcast problem. Secondly, was the ESPNHD feed (as you watched it) ever blurry? Thanks again! His response: The intermittent blurriness you saw was due to the fact that WPVI was playing with their Harris Flexcoder and had it set to adaptive and not fixed to see if it would deal with an issue with the color red during certain broadcasts. ABC has specifically informed all of their stations to set the Flexcoder to fixed and I was shocked to see them fool around with it in this way when they knew it would cause the whole screen to go blurry. This has been known in the industry for several years. In fact, Comcast Sportsnet had the same issue about three years ago which was changed after I told them about it. At the time, they had no one on their staff who had an HD set at home so no one noticed it. As a result, [they have] asked me to check out their broadcasts for problems which I still do, although they don't have many these days thankfully. My concern was the difference in the picture once the intermittent stuff stopped. It was NOT on the ESPN broadcast anyway. The issue was the lack of clarity or snap that was missing from WPVI-DT. That was due solely to their multicasting efforts. Thanks for the feedback! |
