Embodiment 1

[0057] Such as figure 2 As shown, it is a schematic diagram of the steps of the output method of multimedia data in Embodiment 1 of the present invention, and the method includes:

[0058] Step 101: The STB receives multimedia data sent by the first display device.

[0059] If the first display device is connected to the set-top box in a wireless manner, then in step 101, the first display device may send multimedia data to the set-top box through a wireless multimedia protocol message (such as a UDP message). If the first display device is connected to the set-top box through HDMI, the first display device can directly send multimedia data to the set-top box through the HDMI interface

[0060] The multimedia data may be video data, or other types of multimedia data.

[0061] Step 102: According to the display capability information of the second display device to receive the multimedia data, the set-top box adjusts the multimedia data sent by the first display device to mu...

Embodiment 2

[0075] Embodiment 2 of the present invention describes the scheme of Embodiment 1 of the present invention in detail through a specific example.

[0076] Assumption: A smart phone and a tablet are respectively connected to the set-top box, and the video data sent by the tablet to the set-top box is expected to be displayed on the smart phone, such as image 3 As shown, the output method of multimedia data mainly includes the following three processes:

[0077] The first process: the process of establishing a wireless connection between a smartphone and a tablet computer and a set-top box. The following takes the establishment of a wireless connection between a smartphone and a set-top box as an example. The process of establishing a connection between a tablet computer and a set-top box is the same and will not be repeated.

[0078] Step 201: The smartphone broadcasts a discovery request (discovery_Request) message.

[0079] Step 202: After receiving the discovery_Request mes...

Embodiment 3

[0106] Embodiment 3 of the present invention describes a multimedia data output device under the same idea as Embodiment 1, such as Figure 6 As shown, the device includes a data receiving module 11, a processing module 12, a storage module 13 and a data sending module 14, wherein:

[0107] The data receiving module 11 is used for receiving the multimedia data sent by the first display device;

[0108] The processing module 12 is configured to adjust the multimedia data sent by the first display device to multimedia data whose display state is adapted to the display capability information of the second display device according to the display capability information of the second display device to receive the multimedia data;

[0109] The storage module 13 is used for storing the multimedia data adjusted by the processing module;

[0110] The data sending module 14 is used for sending the multimedia data stored in the storage module to the second display device.

[0111] The d...

Abstract

The invention discloses a multimedia data output method and equipment. In multi-screen interactive business, conventional set top box is optimized. According to display capacity information of other display devices, the set top box caches the multimedia data as multimedia data of different display statuses rather than transmitting multimedia data sent by a display device to other display devices directly (for example, the set top box caches the original high resolution multimedia data as low resolution multimedia data). According to the display statuses of the cached various multimedia data, the set top box transmits the multimedia data to the display device with suitable display capacity information, so that the display devices of different display capacity can display the received multimedia data correctly after receiving the multimedia data transmitted by the set top box.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a multimedia data output method and device. Background technique [0002] The Internet TV set-top box is a commonly used entertainment device in the home. An Internet TV set-top box can be connected to multiple display devices. It can also be connected to display devices such as projectors or projectors, and can also be connected to display devices such as mobile phones and tablet computers with WiFi functions through wireless methods (such as a set-top box as a WiFi access point). [0003] The multi-screen interactive function between multiple display devices connected to the same set-top box has gradually become mainstream. Take the situation where the set-top box is connected to a TV through HDMI and a mobile phone through WiFi as an example. The stored multimedia data is displayed on the mobile phone. The specific method is as follows: [0004] First, the television trans...
