Description of drawings
Fig. 1 is the structural representation of embodiment of the invention system;
Fig. 2 is the workflow diagram of the embodiment of the invention.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as the structural representation of the invention process system.
The CPU0(central processing unit): be application processor, be responsible for carrying out starting guiding, operating system loading, application program motion;
Playing module comprises: tuner (TUNER), demodulation (QAM), demultiplexing (DEMUX), audio frequency (AUDIO decoding and output, video (VEDIO) decoding and output;
The CPU1(auxiliary processor): the processor of other purposes, very low to the requirement of this processor, can be the simplest 8 single-chip microcomputers, also can be in the symmetric double core processor another;
What be different from prior art is that the design of this hardware circuit has broken through dual processor and replaces the relevant equipment of controls playing, and the state of the good equipment of management that can work in coordination with.
Be illustrated in figure 2 as the workflow diagram of the embodiment of the invention:
Phase I.Bootloader starts guiding: will play non-scrambling string routine by CPU0 and be loaded into CPU1 and go up and activate its operation, this process has comprised and has read and transmitted the parameter that FLASH deposits in advance: frequency, symbol rate, modulation system, video PID, audio frequency PID, volume.This moment set-top box power on 1 second less than time in begun broadcast program.Followed by be that CPU0 continues to carry out conventional initial work on the backstage, the pilot operationp system, bootloader gives operating system (Operating System) CPU0 operation power.Bootloader tells by the start-up parameter that setting passes to operating system operating system and follow-up driver are play relevant equipment (tuner, demodulation, demultiplexing, audio/video decoding and output) with which type of mode initialization.
In general, the video flowing of TV is the scrambling video flowing, by video flowing is carried out scrambling, can prevent the bootlegging to data, and the fail safe of video is provided.But adopt the scrambling video flowing to provide the source to finish formalities such as checking, therefore must wait for after set-top box is finished complete initialization and could play by set-top box and video flowing.
But not the scrambling video flowing does not then need to carry out scrambling such as encrypted authentication operation, and its fail safe is lower, but can play-over, and only need carry out demodulation, demultiplexing, audio/video decoding to the non-scrambling video flowing that obtains from tuner is exportable broadcast.
Second stage.CPU0 proceeds the initialization of operating system, hardware drive program, application program.Wherein hardware driving initialization section need of work is worked in coordination with the equipment that CPU1 is used simultaneously, manage dual processor to playing the State Control of relevant equipment, caused audio frequency and video marked halt or unusual when avoiding CPU0 on the operating system level level, to reinitialize equipment.Because play relevant equipment has been finished the related hardware register in the startup vectoring phase setting, therefore initial work concentrates on to the operating system device registration herein, the needed software resource of the equipment that creates, but and the HAL hardware abstraction layer of such equipment of inoperation, i.e. device register.The application initialization aspect comprises: equipment is opened, and the CA(condition receives) initialization, menu demonstration etc.And this moment, CPU1 continued controlling the non-broadcast that adds flow-disturbing, and interruption, the equipment state control of relevant equipment is play in management, in this stage, plays relevant equipment and is in fact still being administered by CPU1.
Phase III.After treating that the whole system initialization finishes, stop CPU1 to playing the control of relevant device, then Play Control power is returned CPU0, the scrambled program that CPU0 is play when then switching to last the shutdown fast, from then on, upper level applications begins by driver operational hardware equipment, and whole handoff procedure is keeping taking over seamlessly.After this CPU1 makes his usefulness in addition.
