Functional Needs: Decoders
The Advantage of Open-Standard Encoding
Although the enormous size of raw digital video streams makes source compression essential to managing their transmission and storage, on the receiving end, compressed video streams must be decompressed for use. In other words, every location where compressed video streams are viewed requires a decoder, able to restore the compressed stream to an accurate representation of its original (pre-compressed) state.
Since compressed transmissions are typically viewed at multiple locations, efficient decoding is a vital consideration in selecting an encoder. Encoders that support popular open standards, like H.264/AVC, offer customers the widest choice of decoding options. Choices range from freely available software decoders, to inexpensive set-top boxes, to professional IRDs; with each alternative available from multiple vendors.
In other words, choosing a Telairity open-standard H.264/AVC encoder never locks you into a narrow set of decoding options. To the contrary, you are always free to choose whatever solution best fits your needs, as well as to change solutions as your circumstances change.
Available Options
Want the most economical decoder? Competition among many competing vendors keeps prices down to a minimum. By shopping around, you can usually find a great deal.
Want to buy from a preferred supplier? Virtually every decoder vendor either already does or shortly will produce a H.264/AVC line. Finding the right model for your requirements is likely as simple as explaining your requirements to a sales representative.
Want an encoder that interoperates smoothly with your own proprietary H.264/AVC decoder? Telairity is happy to test with your device and guarantee compatibility.
Whatever solution you chose for decoding our compressed H.264/AVC stream, we will work with you to optimize your entire end-to-end transmission chain to achieve the best possible picture at your target bitrate. Best of all, our standard risk-free 30-day evaluation period provides ample opportunity to test any encode-decode solution before purchasing gear.
Telairity IRD
For customers looking for an efficient encode/decode solution from a single vendor, Telairity offers the BE-IRD-5502, guaranteed to interoperate with any Telairity encoder.
The BE-IRD-5502 comes with Tuner options for satellite, cable, and terrestrial transmissions included. Also accepts DS-3 input, ASI input, and IP input. Decodes 2 audio stereo pairs with embedded, analog and digital output; these can be either MPEG-1, Layer 2 or AAC compression formats.
For full information on the BE-IRD-5502, see the Integrated Receiver Decoder in the Products section.
