ATSC Program and System Information Protocol (PSIP). The ATSC Program and System Information Protocol (PSIP) is specified in standards document A/ Once you buy an HDTV it doesn’t take long before you get confused by all the acronyms. We love us some HD, but the days of simply bringing. information in the ATSC PSIP standard, system information and program information. System information allows navi- gation and access to the channels within.

Program and System Information Protocol
PSIP Pro is the system of choice by television station broadcasters who are looking for a proven system at an affordable entry level price. This equipment generates PSIP information. Retrieved 24 March QAM This is a term thrown around a lot these days because it’s actually pretty useful to understand. The one thing we didn’t touch on though was satellite technology and mostly this is because both of the providers in the US require you to use their STBs anyways, and there really aren’t many reasons you’d need to know what types of modulation they used — at least not in the context of this port.
Retrieved from ” https: While understanding the ins and outs of either standard is well beyond the scope of any article, you should know that both use the same size channels 6MHz and that until a channel goes all digital, it is actually broadcasting on both frequencies simulcasting. Views Read Edit View history.
It also serves as a support platform for applications such as data broadcasting. So in other words as technology evolves we find new ways to send more bits across the same 6MHz channel.
Unfortunately in practice this isn’t the case, and our beautiful HD turns into block city. With the advent of HD bandwidth has become a problem for all content providers, but it helps if you understand how it is managed. It is pretty obvious by the latest surveys that most people don’t understand exactly what it takes to enjoy HD on their HDTV, but even if you do, you may not understand what most of it means.
HD 101: What is ATSC, PSIP, QAM, and 8-VSB?
Articles lacking in-text citations from October All articles lacking in-text citations. This is where instead of sending every channel to every house, all the time, only the channels that are being arsc are being sent. Advanced functions such as recurring events, default event, search event gaps, search event overlap and event over run control are provided to minimize user input.
Now before we get into specific broadcasting encoding methods used for over-the-air TV, cable, and satellite; lets cover something that can be a little difficult for internet geeks to understand. Television stations work the same way, but the frequencies are mapped to channel numbers to make things simple — so for example, channel 8 in the US is at Archived from the original on 25 July This is actually pretty cool technology but the problem is there is the off chance that a channel won’t be available when you want to watch it — very rare — and even more common, your one-way CableCARD enabled Media Center or TiVo won’t be able to tune in the channels at all.
Advanced Television Systems Committee.
One way they do this atzc by putting multiple HD streams on one channel. The good news is that while technology continues to change, due to compatibility reasons these technologies evolve slowly. The two channels have no paip on each other, they each have their own discrete channels. Hit us up at ask at engadgethd dawt com and keep an eye on this space — your topic could be next. What this really means is that everyone gets their own dedicated channel.

PSIP is a collection of tables designed to operate within every digital broadcast transport stream. American broadcast television Template: Packet switched vs circuit switched Now before we get into specific broadcasting encoding methods used for over-the-air TV, cable, and satellite; lets cover something that can be a little difficult for internet geeks to understand.
The Program and System Information Protocol PSIP is the MPEG a video and audio industry group and privately defined program-specific information originally defined by General Instrument for the DigiCipher 2 system and later extended for the ATSC digital television system for carrying metadata about each channel in the broadcast MPEG transport stream of a television station and for publishing information about television programs so that viewers can select what to watch by title and description.
Delivering PSIP data is essential for digital terrestrial and cable broadcasters. So even if channel 10 is off the air, channel 12 can’t use the throughput.
Tired of Google’s complicated answers when you asked paip a simple explanation? Please help to improve this article by introducing more precise citations. Each of these channels is like real estate — they aren’t making any more of it — and broadcasters get a license from the FCC to use it with some non-monetary strings attached.
