Problems solved by technology

At present, most consumer electronic products use the 2.4GHz and / or 5GHz frequency bands to access WLAN, but the 2.4GHz and / or 5GHz frequency bands are not suitable for transmitting the currently popular high-definition or ultra-high-definition media data that may be popular in the future
The theoretical bandwidth of the 60GHz frequency band or similar higher frequency bands can reach 7Gbit / s, which is suitable for the transmission of high-definition audio and video data, but its penetration is weak, so if consumer electronics products use the 60GHz frequency band to access WLAN, their power consumption the amount will be large

Abstract

The embodiment of the invention provides a media data transmission method and equipment. The method comprises the steps of controlling media source equipment to establish connection with media presentation equipment on a first frequency band when media data suitable for being transmitted on the first frequency band exists and carrying out transmission of the media data based on the established connection, so that the transmission performance of the media data can be guaranteed and power consumption can be lowered.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a media data transmission method and device. Background technique [0002] With the development of the digital home and the general digitalization of consumer electronic products, more and more digital entertainment devices and home appliances are appearing in the home network. At present, various consumer electronic products begin to support wireless local area network (Wireless Local Area Network, referred to as WLAN) communication capabilities, such as supporting the 802.11 series of standards formulated by the Institute of Electrical and Electronics Engineers (referred to as IEEE), Including 802.11a, 802.11b, 802.11g, 802.11n, and standards such as 802.11ac and 802.11ad that are entering the market. [0003] Among the above-mentioned 802.11 standards, except 802.11ad which uses a 60 GHz frequency band, other standards all use a 2.4 GHz and / or 5 GHz freq...
