Completely free media player to open all video sources including file, disc, url, webcam and other professional features. This is the part two in our series of tutorials in how to use Windows Media Center as a DVR for your high definition clear QAM channels. Unfortunately the operation is most cases is not as plug and play as we would like and I lost a day in the process of figuring a way to make everything work.
In my case, although I knew KTTV-DT (the high definition Fox 11 affiliate in my area) had to be among the found channels, for some reason it wasn’t in the list. Don’t forget to restart the system so the background channel scanning services gets disabled. Here is a tip for anyone who’s channel scans do not pick up some Clear QAM signals in Windows Media Center, and who own a Hauppauge tuner.
A?Reproducir Cualquier Formato de VA­deo o Audio en Nuestro Reproductor Windows Media Player! Windows Media Audio (WMA) is the name of a series of audio codecs and their corresponding audio coding formats developed by Microsoft.
A WMA file is in most circumstances contained in the Advanced Systems Format (ASF), a proprietary Microsoft container format for digital audio or digital video.[17] The ASF container format specifies how metadata about the file is to be encoded, similar to the ID3 tags used by MP3 files.
Since 2008 Microsoft has also been using WMA Professional in its Protected Interoperable File Format (PIFF) based on the ISO Base Media File Format and most commonly used for Smooth Streaming, a form of adaptive bit rate streaming over HTTP.
Each WMA file features a single audio track in one of the four sub-formats: WMA, WMA Pro, WMA Lossless, or WMA Voice.
WMA can encode audio signals sampled at up to 48 kHz with up to two discrete channels (stereo).
Fundamentally, WMA is a transform coder based on modified discrete cosine transform (MDCT), somewhat similar to AAC, Cook and Vorbis. Like AAC and Ogg Vorbis, WMA was intended to address perceived deficiencies in the MP3 standard. Certified PlaysForSure devices, as well as a large number of uncertified devices, ranging from portable hand-held music players to set-top DVD players, support the playback of WMA files.
Screenshot of Windows Media Encoder 9 Series, displaying new encoding options for Windows Media Audio 10 Professional. Windows Media Audio Professional (WMA Pro) is an improved lossy codec closely related to WMA standard. The codec's bit stream syntax was frozen at the first version, WMA 9 Pro.[23] Later versions of WMA Pro introduced low-bit rate encoding, low-delay audio,[24] frequency interpolation mode,[25] and an expanded range of sampling rate and bit-depth encoding options. Despite a growing number of supported devices and its superiority over WMA, WMA Pro still has little hardware and software support.
Label for 5.1 surround sound, the maximum channel configuration for Windows Media Audio Lossless. Windows Media Audio 9 Lossless is a lossless incarnation of Windows Media Audio, an audio codec by Microsoft, released in early 2003. Windows Media Audio Lossless (WMA Lossless) is a lossless audio codec that competes with ATRAC Advanced Lossless, Dolby TrueHD, DTS-HD Master Audio, Shorten, Monkey's Audio, FLAC, Apple Lossless, and WavPack (Since late 2011,[36][37][38] the last three have the advantage of being open source software and available for nearly any operating system.) Designed for archival purposes,[39] it compresses audio signals without loss of quality from the original using VBR. Windows Media Audio Voice (WMA Voice) is a lossy audio codec that competes with Speex (used in Microsoft's own Xbox Live online service[46]), ACELP, and other codecs.
It is important to note that both MP3 and WMA encoders have undergone active development and improvement for many years, so their relative quality may change over time. The FFmpeg project has reverse-engineered and re-implemented the WMA codecs to allow their use on POSIX-compliant operating systems such as Linux. Software that can export audio in WMA format include Windows Media Player, Windows Movie Maker, Microsoft Expression Encoder, Sony Sound Forge, GOM Player, RealPlayer,[62] Adobe Premiere Pro,[63] Adobe Audition,[64] and Adobe Soundbooth.[65] Microsoft Office OneNote supports encoding in all WMA codecs,[66] and Windows Media Encoder supports all available bit rate and resolution options as well. The WMA codecs are most often used with the ASF container format, which has an optional DRM facility.

I use the Windows 7 taskbar heavily, because I like being able to launch programs using Win+[number]. In case you do not have administrator privileges you obviously can’t change the path environment variable.
Select Add QAM channel and input the channel name from the SiliconDust website (again, the channel name, not the virtual name. Since you cannot add more then 3 sub channel numbers to the add function in Media Center, try this instead, Install WinTV, and do your scan.
The sole exception to this is the WMA 10 Professional codec whose Low Bit Rate (LBR) mode is only backwards compatible with the older WMA Professional decoders at half sampling rate (similar to how HE-AAC is backwards compatible with AAC-LC).
Metadata may include song name, track number, artist name, and also audio normalization values. Related industry standards such as DECE UltraViolet and MPEG-DASH have not standardized WMA as a supported audio codec, deciding in favor of the more industry-prevalent MPEG and Dolby audio codecs.
These formats use different codes that are technically distinct and mutually incompatible.[clarify] Each codec is further explained below. Colloquial usage of the term WMA, especially in marketing materials and device specifications, usually refers to this codec only. The bit stream of WMA is composed of superframes, each containing 1 or more frames of 2048 samples.
It retains most of the same general coding features, but also features improved entropy coding and quantization strategies as well as more efficient stereo coding. A WMA 10 Pro file compressed with frequency interpolation mode comprises a WMA 9 Pro track encoded at half the original sampling rate, which is then restored using a new compression algorithm.[26] In this situation, WMA 9 Pro players which have not been updated to the WMA 10 Pro codec can only decode the lower quality WMA 9 Pro stream.
The Logitech Squeezebox Touch now supports the format natively despite previously only supporting it via transcoding.
Designed for low-bandwidth, voice playback applications,[47] it employs low-pass and high-pass filtering of sound outside the human speech frequency range to achieve higher compression efficiency than WMA.
The Microsoft Zune media management software supports most WMA codecs, but uses a variation of Windows Media DRM which is used by PlaysForSure. The rockbox project further extended this codec to be suitable for embedded cores, allowing playback on portable MP3 players and cell phones running open source software. Windows Media DRM, which can be used in conjunction with WMA, supports time-limited music subscription services such as those offered by unlimited download services, including MTV's URGE, Napster, Rhapsody, Yahoo! As a result of this, and the fact that it’s written in Java, it has some non-standard behavior characteristics on its edges. My desktop and laptop are configured identically, so Win+1 always opens Chrome, Win+5 is always iTunes. You should now be able to pin Eclipse to the taskbar, giving it a home among the rest of your permanently docked programs. They just forgot to say where to add the lines to the .ini add them to the beginning and not the end.
Also, for posterity sake, you could make a shortcut to Eclipse, then pin the shortcut to the taskbar. This part will describe how to add missing channels and set the proper Guide source so the right guide information and schedules are displayed. At this point the channel will appear in the Guide and you can try to test it to see if you actually can get any signal. You’ll need to select the right source from Windows Media Center EPG that will appear in the Guide for the new channel. If there are channels that are picked up by that, but not in WMC, go to settings in WinTV, and click on all channels.

Full fidelity decoding of WMA 10 Professional LBR bitstreams requires a WMA version 10 or newer decoder.
This container can optionally support digital rights management (DRM) using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing function.
Notably, many of the WMA standard's low bitrate features have been removed, as the core codec is designed for efficient coding at most bitrates. In the absence of the appropriate audio hardware, WMA Pro can automatically downmix multichannel audio to stereo or mono, and 24-bit resolution to 16-bit during playback.
The result is a bit-for-bit duplicate of the original audio file; in other words, the audio quality on the CD will be the same as the file when played back. Like WMA Standard, WMA Lossless is being used by a few online stores to distribute music online.[44][45] Similar to WMA Pro, the WMA Lossless decoder can perform downmixing when capable audio hardware is not present[citation needed]. One of them is the inability to pin the program to the taskbar like you can with most Windows programs. If all is good, you are ready for the next step, changing the Guide source for the new channel, so you can get access to EPG – Electronic Programming Guide. Each frame contains a number of blocks, which are 128, 256, 512, 1024, or 2048 samples long after being transformed into the frequency domain via the MDCT.
Furthermore, the MDCT implementation used in WMA is essentially a superset of those used in Ogg and AAC such that WMA iMDCT and windowing routines can be used to decode AAC and Ogg Vorbis almost unmodified. As of 2012, the ffmpeg and libav projects have open source WMA Lossless decoders based on reverse engineering of the official decoder.
For non-development purposes, you’ll generally want to be using the latest version of the JRE. Audio signals that are deemed to be imperceptible to the human ear are encoded with reduced resolution during the compression process. In the frequency domain, masking for the transformed samples is determined, and then used to requantize the samples. Players that support the WMA format but not Windows Media DRM cannot play DRM-protected files. Finally, the floating point samples are decomposed into coefficient and exponent parts and independently huffman coded. The primary distinguishing trait of the WMA Standard format is its unique use of 5 different block sizes, compared to MP3, AAC, and Ogg Vorbis which each restrict files to just two sizes. The format has never been publicly documented, although an open source decoder has been reverse engineered for non-Microsoft platforms by the libav and ffmpeg projects. Click on the category you want and a drop down list of all available channels appears in VLC media player. Just click on the channel you want to watch and streaming should begin almost immediately. How does it work? VLC media player also has great hotkey support and if you take the time to learn the shortcuts so it can be controlled without touching your mouse. VLC media player isn't as intuitive as iTunes as a media manager, but it's a much more flexible player in terms of file formats. In this dialog window use the exact Call Sign name from the previously highlighted channel, ex. The preferences menu is comprehensive without being overwhelming, and there is extensive documentation online. Complete and free VLC Media Player is quite simply the best multimedia application for Windows and Mac. Go to the Media Center (It will already be open) and look at the guide for the new channel, and test it out.
