  • Introduction of new generation Bluetooth Audio (LE Audio) – Audio Rendering Control
    LE Audio LE Audio is based on Generic Audio Framework which consists of four building blocks for integrating in different audio products. Generic Audio Framework of LE Audio is a middleware designated for configuration and utilized by upper Profiles. The middleware includes Audio Content Control, Audio Rendering Control, Audio Topology Control and Audio Streaming Control. Each building block uses Client/Server mode defined in the GATT specification so that Client can send control command to Server to modify value of characteristic and also Server can initiate sending change of its characteristic value to Client via Notification. Architecture of LE Audio is illustrated in picture below, the blue areas mean completed and adopted specifications and the gray areas mean specifications that are under development. The specifications in red box of the lower right corner are the latest Audio Rendering Control related specifications which were officially adopted by Bluetooth SIG on 15 Dec 2020. Audio Rendering Control is defined based on Volume Control Profile (VCP) which includes Volume Controller and Volume Renderer roles. Volume Controller is acted as GATT Client while Volume Renderer is acted as GATT Server. Volume Renderer as GATT Server must support Volume Control Service (VCS) and may optionally support Volume Offset Control Service (VOCS) & Audio Input Control Service (AICS). The relationship of Audio Rendering Control related Profile and Services is illustrated in picture below: An example of Audio Rendering Control implementation in actual product is shown in picture below. AICS is applicable for devices with multiple audio input types and VOCS is applicable for devices with multiple audio speakers. VCS (Volume Control Service) defines characteristics related to volume control such as volume setting, mute control, as shown in table below: AICS (Audio Input Control Service) defines characteristics related to audio input control such as audio input state, audio input type, audio input description, as shown in table below:  VOCS (Volume Offset Control Service) defines characteristics related to volume offset control such as volume offset, audio output positions, as shown in table below: Audio Rendering Control is one of the four building blocks defined in Generic Audio Framework of LE Audio, other building blocks related specifications to be released by Bluetooth SIG in 2021 and we will introduce them in timely manner, just stay tuned!

  • Introduction for the new generation Bluetooth Audio (LE Audio) - New audio codec LC3
    LE Audio  Bluetooth SIG introduced and demonstrated new generation Bluetooth Audio – LE Audio in CES 2020.  Classic Audio operates on the Bluetooth Classic radio while LE Audio operates on the Bluetooth Low Energy radio. LE Audio will not only support development of the same audio products and use cases as Classic Audio, it will introduce exciting new features that promise to improve their performance as well as enable the creation of new products and use cases. New Audio Codec LC3 LC3 means Low Complexity Communications Codec. Bluetooth SIG organized members including world class audio codec R&D companies to develop the new codec by using state of art audio codec algorithms and finally LC3 codec was adopted and released by Bluetooth SIG on 15 Spec 2020.  All LE Audio Profiles will be required to implement the advanced LC3 codec.  LC3 is an efficient Bluetooth® audio codec for use in LE Audio profiles. It is capable of encoding speech and music at various bitrates and can be incorporated in any Bluetooth audio profile. To increase the audio quality, it is strongly recommended to implement PLC (Packet Loss Concealment) at receiving ends of audio connections. The role of PLC is to conceal the effect of unavailable or corrupted frame data for decoding (an example of PLC is provided in the LC3 codec specification). Some of the technical properties of LC3 include: ●It is a block-based transform audio codec ●It provides a wide range of usable bitrates ●It supports a frame interval of 10 ms and 7.5 ms ●It supports the following bit depths: 16, 24, and 32 bits per audio sample ●It supports an unlimited number of audio channels ●It supports the following sampling rates: 8 kHz, 16 kHz, 24 kHz, 32 kHz, 44.1 kHz, and 48 kHz The new LC3 provides higher quality at the same rates as SBC, or even better quality at a much lower data rate. LC3 supported codec parameters are listed in following table: Providing high quality even at low data rates, LC3 will bring tremendous flexibility to developers, allowing them to make better design tradeoffs between key product attributes, such as audio quality and power consumption. There are different ways to judge the quality of a codec. The most common way is live listening comparison for people to listen and compare the audio after it has been compressed and decompressed. Other ways include standard quantitative methods for measuring performance of audio codecs, such as the one shown in the graph below that compares the performance of LC3 to SBC.  A few notes about the above graph: ●The X-axis represents various bitrates for each SBC and LC3 ●The Y-axis represents a grading scale (0 ~ 5) as defined in ITU-R BS.1116-3 (PDF), which presents Methods for the subjective assessment of small impairments in audio systems If you look at the 345-kbps bit rate for example, you’ll see that SBC scores a value just above 4.0, whereas LC3 scores an even higher amount with less than half the bit rate (160 kbps) The release of LC3 represents the completion of the second of the three key building blocks. The Bluetooth SIG member community is currently hard at work developing new profile specifications that define interoperable support for existing and new audio products and use cases, including hearing aids and Audio Sharing. As we’ve learned in this article, the new LE Audio standard, including LC3, marks a very exciting and important milestone in the development of the Bluetooth® technology standard, one that will enable the advancement and innovations in wireless audio for years to come! It is notable that according to Bluetooth® Patent/Copyright License Agreement use of LC3 does not need to pay patent royalty if products using LC3 coded passed through the Qualification Process.  As leader of Bluetooth Qualification Service provider AGC always follows development of Bluetooth technologies and committed to provide excellent services to Bluetooth SIG members.  Reference: https://www.bluetooth.com/specifications/le-audio/

  • PSE
    Summary Japan PSE is mandatory safety certification, evidence of the electronic electrical products has passed the Japanese electrical product safety act (DENAN Law) or international IEC standard safety standard test. Japan DENAN electrical and electronics products can be divided into two categories: A specific electrical products (specified products), including 116 kinds of products; B non - specified products, including 341 kinds of products. Specific electrical product must be authorized by the Japanese ministry of economy of the third party certification body products and factory test equipment inspection, issuance of PSE certification, certification valid between 3 to 7 years, and labeled with PSE diamond in products. Non specific electrical products is proved by means of self-examination and declare conformity of the product, and labeled with PSE circle on the product. Japan's benchmark electrical product safety technology has two kinds: (1)The province to item 1 benchmark, refers to the domestic technical standards; (2)The province to item 1 benchmark, that is coordinated with the IEC standards. Need to pay attention to, the province has standard item 1 and 2 benchmark is the province that established according to the standard system of independently, to pay attention to not be able to mix these two standards. In the enforcement of rules don't watch the first 2 specifies the name of "electrical appliances", and as stipulated in the electrical products of the "type to distinguish". "Type" refers to the structure, material, or performance, "type to distinguish between" refers to the product safety aspects we confirmed by the structure of the scope of the same nature, material or performance, or a combination of all three. In a wide variety of products type, according to the nature of roughly the same elements and divided into different groups, this is the "type". Therefore, it is important to note that its varieties division and model may not be consistent with enterprise. AGC can be done directly in the domestic circle PSE test and issue a report issued the certificates and the type of table, the test results have been obtained METI's approval. lithium battery PSE On January 18, 2008, the Japanese economy, trade and industry (METI) released the cabinet according to the electrical appliance and material safety law enacted law, a specific range of lithium ion battery has been included in the directory for electrical appliance and material safety products, since November 20, 2008, exports to Japan of the particular range of lithium ion battery, must conform to the requirements of the law about supplier compliance declarations, and listed on the relevant PSE marks must be paste Specific range is: limited to the energy density of not less than 400 wh/L of secondary batteries, batteries, but does not include car with secondary lithium ion batteries, not including electric bike, medical equipment, industrial equipment used in secondary lithium ion battery, also does not include welding way or the battery in the similar way to fix battery installed on the equipment (cannot be easily shift), or those with special structure of the battery.
