It would be just a continuous tape . The tape would go past the playback head, the erase head then the record head . It would require a great big reel of tape . While not impossible it does not seem all that practical . Besides, the heads would become so dirty that they would have to stop the machine to clean the heads at least once a day, perhaps more . But in these digital days, I doubt if they would use tape at all . Is it, perhaps, something similar to a DVD rom? I have a DVD rom and I can record and playback at the same time but I cannot erase while recording, so if that were the method, they would run out of room before too long . So how do they do it? Thanks for your help .	Roscoe (6288)

The TV broadcast is (As far as I'm aware) recorded and the files it saves to the HDD are "split" into, say, 1GB files. As the files are played and finished, they are then deleted, and the system then rotates onto the next file seamlessly during playback. Similar thing happens when you play back DVD files from a DVD disc, the main movie is quite likely several 1GB .VOB files long, but the DVD player automatically jumps over to the next one. It's just that in this case, they have software continuously feeding it a new file. ...or so I'd imagine, this isn't all purely speculation, but rather a semi-educated guess :)	Chilling_Silence (9)

Jane hears the sound and wants to watch on her computer – her clip starts at the beginning and she continues to watch with her sound and pictures being 30 seconds behind Jim’s. Then Dmitri and Ivana in Russia do the same - 30 seconds apart. They all start watching at the beginning regardless of how many others are already watching. YouTube is a giant shared network storage device. The TV stations rely on shared network storage devices.	coldot (6847)

1314727	2012-11-26 02:13:00	The real question is why bother, I think they are just keeping the channels active until they might eventually have a need for more channels. I have a TiVo, I can record anything I want to see if I'm not home.... broadcasting it twice seems pointless.	dugimodo (138)

Also it doubles their marketing (ad revenue) and I don't think they'd have to pay as much for a re run so it must make them some money. Despite the fact you have a TiVo most people don't and I can see the 1hr timeshift being valuable for some.	The Error Guy (14052)

I had no idea at all as to how that worked. What you have said makes sense. I could not see how they could delete the file that they were recording and playing at the same time, but if it is, as you say, made up of many files, then the played back files can be deleted as soon as they have completed each individual 1GB. Thanks for your explanation. Nice to have a sane voice amongst the crowd.:thanks	Roscoe (6288)
