Described interactive optical disc apparatus also comprises the DVD video playback engine 200 operation associated with described ENAV engine 100.Content providing server 300 links to each other with the network manager 10 of described ENAV engine 100, thereby various content informations are provided.Various ENAV content-datas comprise and the video data associated audio data file that reads from interactive DVD 400.For example, voice data may be a foreign language track of following the video data that is stored in the interactive DVD 400.
ENAV impact damper 11 can logically be divided into first impact damper (impact damper 1) and second impact damper (impact damper 2).As shown in Figure 2, the main A/V stream and ENAV content information reproduced in synchronization, for example audio content data that from described content providing server 300, provides or the audio content data that replaces that from described interactive DVD 400, read.
Therefore, the owner of described interactive DVD player can watch the A/V stream that reads and/or watch the ENAV audio content data of the video content data that ENAV audio content data and described content providing server 300 provide from described interactive DVD 400.
When because the loss of network connectivity of the Internet or be included in the limited memory space of the memory buffer 11 in the interactive DVD player, when temporary transient interruption of audio content data generation that content providing server 300 provides or delay, ENAV engine 100 is provided by the voice data that sequence of operations come again synchronous video data that reads from interactive DVD 400 and content providing server 300 to provide.In other words, when producing synchronization failure during video data that reads and the audio content data synchronized playback from described interactive DVD 400, a series of synchronous again operations will be performed, and will describe in detail it below.
Fig. 3 and 4 is illustrated in according to data transmission/receiving course between the interactive optical disc apparatus of the first embodiment of the present invention and the content providing server 300 and data reproduction process.For example, when producing user's request by the script appointment or incident during the video data playback at interactive DVD 400, the interactive DVD player is carried out the initialization operation (S10) to the Internet.Therefore, described content providing server 300 is carried out a series of corresponding operations (S11).
Subsequently, described interactive DVD player produces the order of request transmission corresponding to the ENAV content information of current video data.For example, ask and current video data associated content video data file (S12) by sending a command to described content providing server 300.
The audio content data of content providing server 300 searching request transmission in the database (not shown).Subsequently, content providing server 300 transmits (S13) with audio content data as the ENAV content information.The interactive DVD player downloads is provided as the video data of ENAV content information form, and it temporarily is stored in as preceding with reference in the described ENAV impact damper 11 of Fig. 1.Then, the interactive DVD player is by reappearing this audio content data synchronously with audio content data and the video data that reads from interactive DVD 400.
When the transmission owing to the ENAV content information is cancelled, during the synchronization failure of described video data and audio content data, the interactive DVD player is by the reproduction time (T1) of this instantaneous video data of sign, predetermined amount of time (A) is added to the reproduction time of the video data of described sign, then the result be multiply by the bit stream of audio content data, calculate the off-set value (S15) of audio content data that can be synchronous again.Because the bit rate of described audio content data is constant bit rate (CBR), off-set value will be simply calculated according to " off-set value=(T1+A) * CBR ".
Predetermined amount of time (A) can be set to and the playback speed of video data and the proportional arbitrary value of message transmission rate of network.The order of the ENAV content information that the off-set value that interactive DVD player generation request transmission and described method calculate is corresponding sends to order content providing server 300 (S16) then.
As described in Figure 4, the main A/V stream that the common playback of interactive DVD player is read and play from interactive DVD 400 wherein keeps synchronously with the audio content data that content providing server 300 provides.
When with the operation of the reproduced in synchronization of described method when unsuccessful, can be after the interactive DVD player be provided at from described content providing server transmission again can synchronous again audio content data, be used for and sequence of operations that video data synchronously reappears again thereby carry out.
In the second embodiment of the present invention; when the request of the user by the script appointment or incident take place; in the middle of the sequence of operations of the normal playback that is recorded in the main A/V stream in the interactive DVD 400 is read and is play in execution; the interactive DVD player is carried out a series of being used for and is kept synchronously reappearing the operation of ENAV audio content data with described main A/V stream such as video data, and these data are downloaded and temporarily are stored in the impact damper 11 of described interactive DVD from IDVD dish 400.
When the limited capacity of memory buffer 11 causes synchronization failure during with the reproduced in synchronization of described method, as previously mentioned, the interactive DVD player is by the reproduction time (T1) of the instantaneous video data of sign, a predetermined time quantum (A) is added to the reproduction time of the video data of described sign, then the result be multiply by the bit rate of described audio content data, calculate one can be synchronous again the off-set value of audio content data.
Because the bit stream of described audio content data is a constant bit rate (CBR), off-set value will be simply calculated according to " off-set value=(T1+A) * CBR ".In this case, predetermined amount of time (A) can be set to and the proportional arbitrary value of the playback speed of video data.
The interactive DVD player will reappear and the synchronous audio content data of described video data after the described off-set value corresponding audio content-data of searching for and reading and calculate with described method usually.
In the 3rd embodiment of the present invention, with reference to as described in the Figure 4 and 5, audio content data stream transmission or that read from interactive DVD can comprise and is used in described audio content data and synchronous again out of Memory between such as the described main A/V stream of video data from described content providing server 300 as preceding.
For example, as shown in Figure 6, calculate the off-set value synchronous again for faster more accurately, will be included in about the more than one information in the total byte size information of per second bytes of audio data number, every frame bytes of audio data number, audio content data on the more than one header of head zone of described audio content data stream with video data.
In addition, other information both can be included in described audio content data stream head zone and/or the service load region header on, also can be included in off and on the whole zone of described audio content data stream.
At initial return period transmission or that be recorded in the audio content data stream in the described interactive DVD 400 from described content providing server 300, the interactive DVD player searches is also quoted, and for example comprises the total byte size of the per second bytes of audio data number in the header zone in the head zone of described audio content data stream, every frame bytes of audio data number, audio content data.
When the video data that from described interactive DVD 400, reads with the synchronous playback of described audio content data during synchronization failure when taking place, go out again synchronous off-set value with reference to described other information calculations.Lift a numerical example, if per second bytes of audio data amount is 1KB/ second, every frame bytes of audio data number is the 9KB/ frame; Instantaneous when needing again synchronously owing to synchronization failure is 100 seconds, and then the off-set value of calculating synchronously again is second 100KB=100 second * 1KB/.
In fact, because voice data is to be that unit reappears with the frame and every frame bytes of audio data number is 9KB, wherein the off-set value that calculates according to described method is that the actual of audio frame of 100KB will be in 99KB.Therefore, in this specific situation, the request of producing of interactive DVD player begins the order of transmission of audio content-data again from position 99KB, and this order is sent to content providing server 300.
Described content providing server 300 is quoted the order that receives by described process, and carries out sequence of operations and search for and read frame start position corresponding to the audio content data of described off-set value, thereby transmits corresponding voice data.This interactive DVD player can be carried out the normal reproduction of the audio content data that receives by described process by synchronous again with the video data that reads from described interactive DVD 400 then.
On the other hand, when read and play from interactive DVD 400 described audio content data during synchronization failure when taking place, the interactive DVD player searches also reads the frame start position corresponding to the audio content data of the off-set value that calculates with described method from described interactive DVD, and by carrying out normal reproduction again synchronously with described video data.
When the frame start position of the off-set value that calculates with described method surpasses the total byte size of described audio content data, the interactive DVD player determines that this off-set value is incorrect, and carry out the operation of calculating off-set value once more, perhaps determine to be impossible again synchronously and to carry out a series of corresponding operations, announcement information for example is shown to report synchronization failure again.
The present invention can provide a kind of because the situation of having a mind to the synchronization failure that interrupts of the connection of the Voice ﹠ Video that the selection of trick play functions is caused by the user, comprises because the device of normal reproduction under the situation of the synchronization failure that external cause causes.For example, if the user deliberately jumps section or changes the non-video of in turn watching of broadcasting speed on the direction of advancing or retreating, with will losing synchronously of content providing server 300.Therefore, the logical time marking that stops that skill is play of the present invention calculates off-set value for the synchronous again time, and carries out again the frame start position and the video data of audio content data synchronous.
Reproduction is very useful invention according to the method for the content information of interactive optical disc apparatus of the present invention, can make the owner of interactive optical disc apparatus hear all audio content data of following the video data in the interactive DVD 400, not be stored in the interactive DVD 400 for these audio content data of consideration to the space.
