China's high-definition wireless audio standard released, Huawei FreebudsPro obtained the first certification

Recently, China Electronic Audio Industry Association, China Electronics Technology Standardization Institute, and more than 30 companies including Huawei, Xiaomi, OPPO, Vivo, Hengxuan, and Jerry jointly released the "High-Definition Wireless Audio Technology and Equipment Specifications and Test Methods". Referred to as HWA standard. Huawei executive director Yu Chengdong said that Huawei FreebudsPro2 is the world's first TWS headset to receive HWA certification.

Leland Reviews: The release of the HWA standard sets a specification for the definition of domestic high-definition wireless audio. The HWA standard is different from the previous HWA protocol, which is a Bluetooth codec protocol, mainly targeting Sony's LDAC. The HWA standard released this time can be regarded as a certification standard, and the target is the gold standard Hi-ResAudioWireless formulated by Japan's JAS.

This standard does not restrict which wireless audio codec protocols are used by certified devices, but the parameters must be up to standard. For example, it is proposed in the standard that the high-definition audio codec technology requires that the highest sampling rate is greater than or equal to 96kHz, the bit width supports 24bit, and the highest supported bit rate is above 600kbps.

It can be seen from the official website of the HWA Alliance that the standard audio Codec solutions include LC3+, LHDC, LDAC and aptXAdaptive. The first two need to pay the authorization fee to the corresponding company, such as Taiwan Shengwei Advanced Technology, and the codec authorization of the latter two It is controlled by Sony and Qualcomm. In terms of chip solutions that meet the specifications, HWA has not yet listed the product list, but with the official opening of certification, it is believed that chips supporting the above decoding solutions will soon be certified by HWA.

The display panel dragged down TCL Technology's net profit in the first half of the year, and the new energy photovoltaic business doubled

On the evening of July 14, TCL Technology released the 2022 semi-annual performance forecast. It is expected that the operating income of H1 in 2022 will be 84 billion yuan to 85.5 billion yuan, an increase of 13% to 15% over the same period of the previous year; it is expected to achieve net profit attributable to the parent in the same period It was 650 million to 750 million yuan, down 89% to 90% over the same period last year.

Even if the revenue and performance contribution of H1TCL Technology's new energy photovoltaic and semiconductor materials increase significantly in 2022, it will be difficult to make up for the gap caused by the rapid decline in revenue from the semiconductor display device business. Under the low tide of consumer electronics, TCL Technology, like most display panel manufacturers, cleared inventory by reducing prices to reduce losses caused by declining demand.

But TCL Technology's forecast revealed a more important point that the new energy photovoltaic business revenue showed strong performance. It can be seen that, with the heavy hit of consumer electronics, new energy photovoltaics will become one of the few confident industries in 2022, supporting the sustained and rapid growth of the performance of upstream and downstream enterprises in the industry chain. The reason why new energy photovoltaics can continue the high prosperity of last year this year is the support of national policies. According to the statistics of the policies of the central ministries and commissions, the PV policy intensity index in 2021 is 201, and the policy intensity in the first quarter of 2022 has reached 70% of the whole year of 2021. The rapid growth of photovoltaic industry policies will accelerate the commercialization of photovoltaics and accelerate the growth of corporate performance.

In order to cope with the declining consumer electronics market, some manufacturers have cut prices to destock and launched new products to stimulate consumer purchases and increase sales. More manufacturers choose to explore new fields and join the high-boom track, such as new energy vehicles, photovoltaics, lithium batteries, Industrial software, etc., seek new opportunities to ensure continuous growth of performance.
