Abstract

A media processing method, device, and system where one or more media receiving clients that have a media processing capability of one or more media playback devices are separately constructed for multiple communications protocols, to-be-played media data that is sent by a media source device and that is to be played by a media receiving client specified by the media source device is received, and the to-be-played media data is sent to a media playback device that is corresponding to the specified media receiving client, for the media playback device to play. Therefore multiple media playback devices may be connected flexibly and simultaneously and a media playback device may be switched as desired during media playback.

First claim

1 . A media processing method, comprising:
determining, by a media processing device, at least one first communications protocol; acquiring a media processing capability and a supported second communications protocol of at least one media playback device; constructing, by the media processing device for each of the at least one first communications protocol, at least one media receiving client that has the media processing capability of the at least one media playback device; sending information about the at least one media receiving client to a media source device using a network interface corresponding to the first communications protocol; receiving, by the media processing device, to-be-played media data that is sent by the media source device and that is to be played by the media receiving client specified by the media source device; and sending, by the media processing device using the second communications protocol corresponding to the specified media receiving client, the to-be-played media data to the media playback device that corresponds to the specified media receiving client, for the media playback device to play.

2 . The method according to claim 1 , wherein acquiring the media processing capability and the supported second communications protocol of at least one media playback device comprises:
finding, by the media processing device, the at least one media playback device by connection to a communications interface of the at least one media playback device; and acquiring the media processing capability and the supported second communications protocol of the at least one media playback device.

3 . The method according to claim 1 , wherein acquiring the media processing capability and the supported second communications protocol of at least one media playback device comprises:
reading, by the media processing device, a port information table of a local area network router that is connected to the media processing device; and acquiring, from the port information table of the local area network router, the media processing capability and the supported second communications protocol of the at least one media playback device that is connected to the router.

4 . The method according to claim 1 , wherein constructing, by the media processing device for each of the at least one first communications protocol, at least one media receiving client that has the media processing capability of the at least one media playback device comprises constructing, by the media processing device with respect to each of the at least one first communications protocol, the media receiving client that has the media processing capability of each media playback device.

5 . The method according to claim 1 , wherein constructing, by the media processing device for each of the at least one first communications protocol, at least one media receiving client that has the media processing capability of the at least one media playback device comprises:
combining, by the media processing device, the media processing capability of the at least one media playback device into at least one type of media processing capability; and constructing, by the media processing device with respect to each of the at least one first communications protocol, a media client that has each type of combined media processing capability.

6 . The method according to claim 1 , wherein constructing, by the media processing device for each of the at least one first communications protocol, at least one media receiving client that has the media processing capability of the at least one media playback device comprises:
determining, by the media processing device, the media receiving client corresponding to the at least one first communications protocol supported by the at least one media playback device; constructing, by the media processing device with respect to each first communications protocol that is not supported by the at least one media playback device, at least one media receiving client that has the media processing capability of the at least one media playback device; and/or constructing, by the media processing device with respect to each first communications protocol that is supported by the at least one media playback device, at least one media receiving client that has the media processing capability that is not supported by the media playback device yet is supported by the media processing device.

7 . The method according to claim 1 , wherein receiving, by the media processing device, the to-be-played media data that is sent by the media source device and that is to be played by the media receiving client specified by the media source device comprises:
receiving, by the media processing device, a network address that is of the to-be-played media data and that is sent by the media source device; and acquiring, by the media processing device, the to-be-played media data according to the network address.

8 . The method according to claim 1 , wherein after receiving, by the media processing device, the to-be-played media data that is sent by the media source device and that is to be played by the media receiving client specified by the media source device, and wherein before sending, by the media processing device using the second communications protocol corresponding to the specified media receiving client, the to-be-played media data to the media playback device that corresponds to the specified media receiving client, for the media playback device to play, further comprises:
unpacking and/or decoding, by the media processing device, the received to-be-played media data according to a first communications protocol corresponding to the specified media receiving client; and encoding and/or packing, by the media processing device according to the second communications protocol corresponding to the specified media receiving client, the to-be-played media data that is unpacked and/or decoded.

9 . The method according to claim 5 , wherein sending, by the media processing device using the second communications protocol corresponding to the specified media receiving client, the to-be-played media data to the media playback device that corresponds to the specified media receiving client, for the media playback device to play comprises synchronously sending, by the media processing device using the second communications protocol separately corresponding to the specified media receiving client that has the combined media processing capability, audio and/or video of the to-be-played media data separately to at least two media playback devices that correspond to the specified media receiving client, for the media playback devices to play.

10 . The method according to claim 1 , wherein the first communications protocol comprises any one of a BLUETOOTH protocol, a universal plug and play protocol, a digital living network alliance (DLNA) protocol, an intelligent grouping and resource sharing (IGRS) protocol, an AIRPLAY protocol, and a Wi-Fi display protocol, and wherein the second communications protocol comprises any one of a high-definition multimedia interface (HDMI) protocol, a displayport protocol, a digital interactive interface for video and audio (DIIVA) protocol, an HDBASET protocol, a mobile high-definition link (MHL) protocol, a THUNDERBOLT protocol, a wireless gigabit (WIGIG) protocol, a wireless home digital interface (WHDI) protocol, and a WIRELESSHD protocol.

11 .- 21 . (canceled)

22 . A media processing device, comprising:
a memory configured to store instructions; and a processor coupled to the memory and configured to execute the instructions to:
determine at least one first communications p
