Embodiment
For allow purpose of the present invention, feature, and advantage can become apparent, preferred embodiment cited below particularly, and cooperate appended Fig. 1 to Fig. 4 is described in detail.Wherein, the configuration of each assembly among the embodiment is the usefulness for explanation, is not in order to limit the present invention.And the part of drawing reference numeral repeats among the embodiment, is for the purpose of simplifying the description, is not the relevance that means between the different embodiment.
Fig. 1 is the structural representation of system of the play multimedia crossfire of one embodiment of the invention.
As shown in Figure 1, multimedia series flow system comprises plural interconnection device (Network-connected Devices) 110～150 and one display unit (figure does not indicate).Wherein plural interconnection device 110～150 communicates with one another by network, and display unit is in order to show a multimedia series flow.In this embodiment, display unit can one of them be arranged in the electronic installation with plural interconnection device 110～150, for example, and devices such as intelligent mobile phone or panel computer.In another embodiment, display unit also can be on the interconnection device in the system of being connected in.The user can be by the interconnection device of various forms, for example, desktop computer (Desktop PC), notebook computer (Notebook), kneetop computer (Laptop PC), panel computer (Tablet PC), mobile phone devices such as (Mobile Phone) are as the carrier of multimedia series flow rating.Must be noted that restrictions such as above-described plural interconnection device quantity, specification, be not limited to shown in the content of accompanying drawing of the present invention and specification.
In another embodiment, interconnection device is arranged at but is not limited in this locality or the home network, and transmission means can wired or wireless mode connect, and for example, bluetooth (Blue-tooth), Wifi, transmission meanss such as Wifi Direct, Zigbee are connected to each other.
When user's 160 desires are play a multimedia series flow by the display unit in the interconnection device 150, in this embodiment, plural interconnection device 110～150 exchanges disposal ability information separately mutually and assigns the interconnection device 110 with optimization process ability information is a main interconnection device.Main interconnection device 110 carries out content decoding according to this multimedia series flow of disposal ability information distribution to all interconnection devices 110～150 of all interconnection devices 110～150, and transmits one and distribute and field data of scheduling information (as shown in Figure 2) to interconnection device 150.Wherein, disposal ability information can be information such as the performance of the central processing unit of all interconnection devices, the acceleration performance of graphic process unit (Graphic Processing Unit acceleration), storage speed and connection frequency range.
Specifically but do not limit to ground for instance, main interconnection device 110 can be according to the frequency range size of decoding capability and the output tape sorting of each interconnection device 110～150, is that unit is dispensed to each interconnection device 110～150 and decodes with multimedia series flow with picture (frame).The state of network was suitably adjusted and is distributed when in addition, main interconnection device 110 also can be according to the ruuning situation of system at that time and transfer of data.
In another embodiment, this distribution and field data of scheduling information can record the assigned multimedia series flow of interconnection device 110～150 and the timestamp sequential scheduling information of multimedia series flow picture (frame).
Then, after all assigned multimedia series flows of interconnection device 110～150 decodings are decoded multimedia series flow, and transmit these decoded multimedia series flows separately to interconnection device 150.In another embodiment, after each interconnection device 110～150 receives separately multimedia series flow, will send interconnection device 150 in real time or simultaneously to after the multimedia series flow decoding separately.At last, as shown in Figure 3, the decoded multimedia series flow that this interconnection device 150 transmits from each interconnection device according to this distribution and field data of scheduling information adjustment, and play this decoded multimedia series flow by display unit and watch to user 160.
In certain embodiments, the multimedia series flow that the user desired to watch can be stored in all interconnection devices in one of them.In other embodiment, multimedia series flow then can be the audio-visual crossfire that is stored in the network (for example, youtube).
Fig. 4 is the flow chart of steps of method of the play multimedia crossfire of one embodiment of the invention.
Please in the lump with reference to figure 1～Fig. 3, when user's desire was play a multimedia series flow by a display unit, at first, in step S201, all interconnection devices exchanged disposal ability information separately mutually.In step S202, judged whether to have an interconnection device of optimization process ability information by display unit.If during an interconnection device that does not have the optimization process ability information as yet ("No" among the step S202), then get back to step S201, all interconnection devices continue exchange disposal ability information separately mutually.If when this display unit is judged the interconnection device with optimization process ability information ("Yes" among the step S202), in step S203, then assigning this interconnection device is a main interconnection device.And this main interconnection device carries out content decoding according to this multimedia series flow of disposal ability information distribution to all interconnection devices of each interconnection device.In step S204, main interconnection device transmission one distribution and field data of scheduling information are to display unit.Then, in step S205, the assigned multimedia series flow of each self-demarking code of all interconnection devices is decoded multimedia series flow, and decoded multimedia series flow is sent to display unit.At last, in step S206, display unit is by this distribution and field data of scheduling information adjustment and play the decoded multimedia series flow that transmits from each interconnection device.
Therefore, by the method and system of play multimedia crossfire of the present invention, the user can be by connecting or being arranged at a display unit of interconnection device and decoding and play the video film of some high density and high compression by the disposal ability of each interconnection device in the system of being combined in.Reduce the user and only utilize All-China Federation of Taiwan Compatriots's net arrangement itself to go the required stand-by period of video film of high density and high compression of decoding, even the video film of high density and high compression and steadily and successfully playing of can decoding rapidly.
Though the present invention discloses as above with preferred embodiment; but it is not in order to limiting the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing various modifications and variation, so protection scope of the present invention is when being as the criterion with defining of claims.
