Embodiment Construction

[0060] The BB part of the existing intelligent mobile terminal, the wireless Internet access data card part of PC and tablet computer are all presented in the form of data during data transmission, and the interface methods are mostly USB, PCIe, SDIO or dual-port RAM. Data transmission needs to encapsulate the data to be transmitted in a corresponding format according to the data transmission protocol of the above interface. Moreover, when the network protocol in the prior art transmits data, the data needs to be encapsulated through a 7-layer protocol standard and transmitted through a specific interface. When data transmission is implemented through the above data transmission methods, a lot of redundant data will be added to the transmission data during each layer of encapsulation, resulting in low data transmission efficiency. In addition, because there are multiple transmission interfaces, it is necessary to use a relatively complex interface transmission protocol, result...

Abstract

The invention discloses a method for transmitting multimedia data and an electronic device. The method comprises the steps that when a first electronic device and a second electronic device need to execute multimedia data transmission, the first electronic device establishes a multimedia data transmission link for transmitting the multimedia data between the first electronic device and the second electronic device; data to be transmitted are acquired, and whether the data to be transmitted are first multimedia data transmitted through the multimedia data transmission link is judged to obtain a first judgment result; if the first judgment result is that the data to be transmitted are the first multimedia data transmitted through the multimedia data transmission link, the first multimedia data are loaded to a physical layer through a first multimedia data interface connected with the physical layer directly and transmitted to the second electric device through the multimedia data transmission link. By means of the method and the electronic device, data of the physical layer can be acquired and transmitted directly, and the multimedia data can be acquired and inserted more quickly.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multimedia data transmission method and electronic equipment. Background technique [0002] At present, with the increasingly mature mobile 3G communication technology, the mobile Internet business has also achieved unprecedented development. For this reason, operators are constantly upgrading and optimizing the network to meet various needs. China Unicom recently announced that it will use HSPA+ with a bandwidth of 21.6Mbps to cover the whole country. Key cities try to meet users' all-round needs for mobile data. [0003] However, these still cannot fully meet the needs of users for high-end mobile Internet services, especially online high-quality video services, such as online video transmission, video conferencing, video surveillance, etc.; [0004] The LTE (Long Term Evolution, long-term evolution) project is the evolution of 3G and the global standard of 3.9G. It i...
