Audio solution offers uncompressed sound

SST Communications' MelodyWing SP advanced wireless audio solution provides uncompressed, wire-equivalent sound quality for home theater surround sound and multi-room audio broadcasting.

SST Communications has released the MelodyWing SP advanced wireless audio solution.

It offers uncompressed, wire-equivalent sound quality for home theater surround sound and multi-room audio broadcasting found in a growing number of home entertainment applications; including HDTVs, home theatres, set-top-boxes, headsets, game consoles, home gateways, multimedia PCs and audio streaming.

The new solution enables each transmitter to wirelessly stream high-quality sound to two full-range speakers and a sub-woofer.

MelodyWing SP Smart Channel automatically selects the un-congested industrial, scientific and medical (ISM) radio bands at both 2.4 and 5GHz, to avoid interference with other wireless equipment and realise pop-free sound effects.

"The consumer electronics market has seen tremendous growth over the past few years, fueled primarily as a result of greatly enhanced video quality in large-screen displays".

"However, still lacking in the market is the superior sound effects that can match the high-definition video experience", said Bing Yeh, President and CEO of SST.

"The MelodyWing SP offered by SST perfectly addresses the needs of the home entertainment market by delivering customers unprecedented sound effects for both multimedia and multi-room music streaming without the need for wires".

"MelodyWing SP will revolutionise home entertainment by redefining the excellence in audio quality for next-generation A/V products".

Daniel Chow, President of SST Communications, added, "Existing wireless audio solutions mostly operate at the congested 2.4GHz radio bands and often exhibit poor audio quality in the form of distortion and noticeable breaks in the audio".

"As a result, consumer demand for wireless surround sound and multi-channel, multi-room audio streaming for digital home entertainment systems have been slow to develop".

"Now, with the introduction of the dual-band 2.4 and 5 GHz MelodyWing SP audio solution with Smart Channel, consumers will be able to enjoy high-quality, pop-free sound effects from wireless surround speakers and high fidelity audio streaming for multi-room broadcasting".

The MelodyWing SP supports two standard digital audio interfaces, the Sony/Philips Digital Interface (S/PDIF) and I2S, offering flexibility in supporting a variety of existing and future consumer electronic audio/video products.

Support for factory programmable worldwide ISM 2.4 and 5GHz radio bands (2.4GHz and 4.9-5.8GHz) and output power allows a single product design to meet the certification requirements of multiple markets.

The Smart Channel feature permits the solution to select an uncongested channel in the available ISM bands to avoid collision with other co-site wireless equipment.

As part of a wireless digital home entertainment system, the MelodyWing SP chipset can be configured in four flexible solutions.

These include: The Single Link wireless configuration mode allows a single wireless S/PDIF or 2.1 channel I2S connection between the audio source, such as a digital TV, and a 2.1 multi-channel speaker system comprised a subwoofer and left and right speakers with a wired connection to the subwoofer.

The Triple Link wireless configuration mode allows three simultaneous wireless connections between the audio source and a 2.1 multi-channel speaker system comprised of a sub-woofer and left and right channel speakers.

The Hextuple Link wireless configuration mode allows six simultaneous wireless connections between the audio source and a 5.1 multi-channel speaker system comprised of a centre speaker, a sub-woofer, left and right front speakers and left and right rear speakers.

The Multi Link wireless configuration mode allows multiple simultaneous wireless connections between the audio source and multiple 2.1 multi-channel speaker system located in multiple rooms.

The physical distance supported is 20m for single-room applications.

The distance supported for the Multi Link solution can be further extended according to customer needs.

The MelodyWing SP supports up to 24 bits per channel for stereo (also compatible with 16-bit stereo), a 90dB dynamic range and offers IEC support for MP3, AAC, AC3 and DTS modes.

The consumer-friendly MelodyWing SP solution requires no firmware drivers or additional hardware for setup.

The embedded SuperFlash memory provides flexibility for system configuration and a 48-bit security code for privacy protection.

The MelodyWing SP wireless audio boards are comprised of the SST11SC03 transmitter board and the SST11SC04 receiver board.
