The Yamaha DSP-1 is a processor of early home theater surround sound equipment, produced in 1986. [1] The DSP-1 (referred to by Yamaha as a Digital Soundfield Processor) allowed owners to synthesize up to 6-channels of surround sound from 2 channel stereo sound via a complex digital signal processor (DSP).
An integrated receiver/decoder (IRD) is an electronic device used to pick up a radio-frequency signal and convert digital information transmitted in it. Consumer IRDs [ edit ]
Devices designed for Enigma2 (i.e. satellite receivers, set-top boxes and IPTV receivers, often simply called boxes) are equipped with one or more DVB-S, DVB-C and DVB-T tuner(s) (unless they are pure IPTV receivers), a Remote control receiver and an Ethernet and/or Wi-Fi network adapter. To receive coded/scrambled programs the box may be ...
If there is no medium/transmitter to put the message through, then the message cannot be delivered to the receiver. If there is no receiver/decoder then a message can’t be decoded and hold any value whatsoever (Eadie and Goret 29). When there is no value to a message the decoder cannot make meaning out of it (Eadie and Goret 29). [2]
A digital TV converter box. A digital television adapter (DTA), commonly known as a converter box, DTV converter , or decoder box, is a television tuner that receives a digital television (DTV) transmission, and converts the digital signal into an analog signal that can be received and displayed on an analog television set.
Some DCS codes are inverted data of others: one code with the marks and spaces inverted may form a different valid DCS code (413 is equivalent to 054 inverted). Because of the use of the 136 Hz code, many receivers will decode a DCS signal when tuned to the CTCSS tone of 136.5 Hz (depending on receiver system tolerance).
Because period is the inverse of frequency, lower tone frequencies can take longer to decode (depends on the decoder design). Receivers in a system using 67.0 Hz can take noticeably longer to decode than ones using 203.5 Hz, and they can take longer than one decoding 250.3 Hz. In some repeater systems, the time lag can be significant. The lower ...
AF (alternative frequencies list) This provides the receiver with a list of frequencies that allows a receiver to re-tune to a different frequency providing the same station when the first signal becomes too weak (e.g., when moving out of range). Before performing the switch, a radio will check for a matching PI code to ensure the AF is the ...
