Method and equipment for multimedia data transmission

Abstract

The invention discloses a method and equipment for multimedia data transmission. A universal mobile terminal and video equipment are matched, multimedia data is collected by utilizing the mobile terminal, and an appropriate coding scheme is selected through combining the hardware specification of the mobile terminal and a connection manner between the mobile terminal and the video equipment, so that the video equipment is capable of implementing optimal multimedia transmission according to the network condition. The performance of a transmission channel and the performance of the terminal are combined and utilized to the greatest extent, and the multimedia data transmission at high quality is implemented. The performance requirements on a set-top box are reduced, the equipment cost for service development is saved and the utilization rate of the equipment is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a multimedia data transmission method. The present invention also relates to a video device. Background technique [0002] Existing set-top boxes are generally connected to TVs for watching TV programs or on-demand videos, and mainly realize audio and video decoding and playback functions. There are no audio and video acquisition modules such as cameras and microphones, and ordinary set-top box chips do not support real-time encoding. In order for the set-top box to support video calls, an external or integrated camera and microphone are required to capture local audio and video. At the same time, the set-top box chip or external camera needs to support real-time encoding with high compression rates such as H.264. At present, a common set-top box can be connected with a dedicated camera and a microphone through a USB interface, or a dedicated all-in-one set-top box integr...

AI Technical Summary

Problems solved by technology

[0004] (1) Ordinary set-top boxes are externally connected with special cameras and microphones. The main disadvantages are: special cameras and microphones need to be purchased additionally, and users need to bear certain equipment costs

Moreover, users mainly use set-top boxes to watch TV, and when the video call service is not used, the utilization rate of dedicated external devices is low

At the same time, the set-top box also needs to choose a chip that supports high-compression rate video encoding such as H.264, or a camera that supports high-compression rate real-time encoding such as H.264, and the cost is relatively high.

In addition, the external device is connected to the set-top box by USB cable. The position of the camera and the microphone is relatively fixed and limited around the set-top box, and it is impossible to move and change the shooting and radio range at will.

[0005] (2) The main disadvantage of customizing a dedicated all-in-one set-top box with an integrated camera and microphone is: customizing an all-in-one integrated camera and microphone requires redesign and mold opening, and the cost is high

When users mainly watch TV and do not use video calling services, the utilization rate of cameras and microphones on all-in-one devices is low

At the same time, set-top boxes need to use chips that support high-compression video encoding such as H.264, and the cost is relatively high

In addition, the camera and microphone of the all-in-one machine are integrated inside the set-top box and cannot be moved. They can only be fixed around the TV and cannot be moved at will or change the range of shooting and radio reception.

[0006] It can be seen that in the prior art, there is no technical solution for using mobile terminals to realize camera and microphone functions for set-top boxes, which cannot make full use of the equipment, thereby increasing the cost and threshold for users to use set-top boxes
