  The AV server apparatus is an AV server apparatus that uses a conventional remote controller as it is, and can reproduce the AV content being viewed among a plurality of television receivers connected to the network while inheriting the reproduction. The command indicating the stop request transmitted from one receiving terminal after the command indicating the reproduction request transmitted from one receiving terminal among the plurality of receiving terminals is received by the command communication unit is the command communication. A content distribution unit that reads a playback AV content that is an AV content requested to be played from one receiving terminal from the storage unit and distributes the playback AV content to the playback receiving terminal that is one receiving terminal; When a command indicating a stop request from the playback receiving terminal is received by the A storage unit that stores a distribution stop position of the playback AV content being distributed, a timer unit that measures an elapsed time from the stop of distribution of the playback AV content, and other receiving terminals other than the playback receiving terminal among the plurality of receiving terminals When a playback request for the same AV content as the playback AV content requested to be stopped from is made, if the elapsed time being measured by the timer unit is within a predetermined time, the playback AV content stored in the storage unit is distributed. When the stop position is set as the distribution start position of the same AV content, and the elapsed time being measured by the timer unit exceeds the predetermined time, the distribution of the same AV content is started at the first position of the reproduced AV content. The seek position control unit sets the seek position control unit to be set as the position and the distribution start position of the same AV content to be distributed to other receiving terminals. It was implemented as a control unit for controlling the content delivery unit to the delivery start position.

The configuration of the AV server system will be described.
An AV (Audio visual) server system 10 shown in FIG. 1 includes a network interface (I / F) unit 11, a server command communication unit 12, a command control unit 13, a content information data unit 14, a content information generation unit 15, and a content storage unit. 16, the server content communication unit 21, the content acquisition unit 22, the seek position control unit 23, the timer unit 24, and the AV server device 1 including the control unit 29, the network 3, the remote controller (remote controller) 41a, and the television 42. The receiving device unit 4 includes a receiving device unit 5 including a remote controller 51 a and a television 52. The timer unit 24 includes timers 24a and 24b.
The seek position control unit 23, which is the main part of the AV server apparatus shown in FIG. 4, is composed of an AV packet detector 231, an AV playback time difference detector 232, a re-start start position determiner 233, and a time code storage unit 234. .
The network 3 includes a LAN (Local Area Network), a WAN (Wide Area Network), and the like. This includes wired, wireless, and even PLC (using power lines).
The remote controllers 41 and 42 use a conventionally used infrared communication system.

The operation of the AV server device will be described.
First, a control command related to viewing of AV content stored in the content storage unit 16 of the AV server device 1 issued by operating the remote controller 41 of the reception device unit 4 is received by a remote control interface unit (not shown) of the television 42, The received control command is supplied to the command control unit 13 via the network 3, the network interface unit 11, and the server command communication unit 12. The content information data unit 14 holds content information related to a list of AV contents stored in the content storage unit 16 generated by the content information generation unit 15 in advance as content information data. The command control unit 13 supplies the content information data held by the content information data unit 14 to the television 42 via the server command communication unit 12, the network interface unit 11, and the network 3, and displays it there. The user requests the playback of a bit stream of AV content desired to be viewed (hereinafter sometimes referred to as streaming) based on the content information relating to the list of AV content displayed on the television 42 by a control command. The command control unit 13 instructs each circuit unit of the AV server device 1 to reproduce the AV content stored in the content storage unit 16 according to the requested control command. The content acquisition unit 22 acquires a bit stream of desired AV content stored in the content storage unit 16. The server content communication unit 21 supplies the acquired AV content to the television 42 via the network interface unit 11 and the network 3. The supplied AV content is displayed on the television 42 and viewed by the user.

When the user operates the stop button of the remote controller 41, a control command for stopping playback is supplied to the command control unit 13. The command control unit 13 causes the timer 24a of the timer unit 24 to start counting. The content acquisition unit 22 executes a cutting sequence for safely ending acquisition of AV content stored in the content storage unit 16. The seek position control unit 23 checks the state of the video packet and audio packet of the bit stream read from the content storage unit 16 for about 5 seconds before the stop button is operated (past), and then starts playback again. Immediately after, the playback position is designated at the position where the synchronization of the video and audio signals is maintained, and the system waits in that state.
The command control unit 13 causes the timer 24b to start counting, for example, for 1 minute after the timer 24a of the timer unit 24 finishes counting, for example, 10 seconds. Here, the timer 24a functions as a function start delay setting timer, and the timer 24b functions as a function end setting timer.

The user who was viewing the AV content on the receiving device unit 4 moves from the room where the receiving device unit 4 is installed to the room where the receiving device unit 5 is installed. After the movement, the remote controller 51 is operated after turning on the power of the television 52 or canceling the standby state of the television 52. A control command for playing back AV content in a state where viewing is interrupted is sent to the command control unit 13. For example, when the operation button of the remote controller 51 is operated within 70 seconds (10 seconds + 60 seconds) after the stop button of the remote controller 41 is operated, playback is started from the stop position of the AV content that has been stopped. Whether to do so is displayed on the television 52. When the user performs an operation of continuously viewing the AV content, viewing from the stop position is resumed. The control unit 29 controls the operation of each circuit unit so that the above operation is performed.
In the case of a conventional home server device, viewing that inherits the viewing state of AV content between different television monitors is not possible. If you want to continue watching AV content on a different TV monitor, it is cumbersome because it is necessary to start playback of the AV content from the beginning of the TV monitor that is inherited and watch it, and send it to the stop position by fast-forwarding etc. It was. In the case of the AV server system 10, the AV server device 1 stores the position where viewing is interrupted in the seek position control unit 23, and viewing inherited by a different TV monitor until the count of the timer 24b exceeds a predetermined time. it can.

  Furthermore, the reproduction start time in the case of inherited viewing is compared between the reproduction time of the audio packet of the AV content and the reproduction time of the video packet of the AV content from the stop position to the past position. A position where the playback times of both the audio packet and the video packet are substantially equal is set in the seek position control unit as a transmission start position. When resuming the reproduction of AV content from the set transmission start position, the reproduction of the AV content being viewed between the plurality of television receivers is performed between the video signal and the audio accompanying the video signal. AV content can be inherited and reproduced while ensuring AV synchronization related to the lip sync.

The synchronized playback of AV content will be further described.
When the AV content stored in the content storage unit 16 is content obtained by broadcast reception, the playback time of the audio signal packet and the playback time of the video signal packet are received as signals at close times. Consideration is made to prevent the occurrence of AV synchronization disturbance when switching channels. On the other hand, in the case of AV content recorded and supplied on a medium, audio packets and video packets may be unevenly arranged. Although video packets and audio packets of a bit stream are not always configured at a predetermined ratio, there are cases where a certain number of video packets are configured in a certain time zone and a number of audio packets are configured in another time zone. For example, in the unit of 10 seconds, even if the playback time of the video packet and the playback time of the audio packet are substantially the same time, the playback time of the video packet and the playback time of the audio packet in units of 1 second are different from each other. May be. When playback of an AV bitstream is paused and playback is resumed from a different time position, playback is performed at a position where the playback time of the video packet and the playback time of the audio packet from the resumed playback position are approximately the same time. It is necessary to set and play as the start position. As a result, it is possible to perform playback while preventing AV synchronization disturbances such as a lack of playback time for video packets resulting in frame drop playback or an excessive playback time of video packets resulting in fast-forward playback. This prevents the lip sync of AV content played back from the middle from being shifted at the beginning.

Next, this will be described in detail.
The operation sequence of the AV server system 10 will be described with reference to FIG.
First, the remote controller 41 in the room where the television 42 is installed is operated to request transmission of content information stored in the content storage unit 16 of the AV server device 1. The command control unit 13 transmits the content information stored in the content information data unit 14 to the television 42. The user makes a reproduction request for desired AV content based on the accumulation of content information displayed on the television 42. The reproduction request is from the position where the reproduction start position is 0 (the first part of the content). The AV server device 1 distributes a bit stream (streaming) of desired AV content stored in the content storage unit 16 to the television 42 via the server content communication unit 21 and the network 3. Displayed on the television 42. The above operation is the operation of phase 1.

  When the user operates the stop button of the remote controller 41, a distribution stop command is transmitted from the television 42 to the command control unit 13 of the AV server device 1. The command control unit 13 causes the AV content disconnection sequence to be executed. When the content acquisition unit 22 has finished reading the content storage unit 16 and retransmits the content, the playback start position is set so as not to cause excess or deficiency in the playback time of each of the audio packet and video packet. The counting of the unit 24 is started. This operation is a phase 2 operation.

Next, the remote controller 51 is operated by the user who has moved to the room where the television 52 is installed, and the generated content information request command is received by the command control unit 13 via the network 3. The command control unit 13 checks whether the time being counted by the timer unit 24 exceeds, for example, 70 seconds. If not exceeded, the AV content information stored in the content storage unit 16 and the content information for which the user stop operation has been performed are sent to the television 52 to display the AV content information. When the remote controller 51 is operated by the user and the AV content information for which the stop operation has been performed is selected, the command control unit 13 starts transmission of the AV content for which the stop operation has been performed from the set playback position. . The selected AV content is reproduced and displayed on the television 52 as an AV content in which synchronization is ensured from the position where the stop operation has been performed, for example, several seconds in the past. This operation is a phase 3 operation.
Between phase 2 and phase 3, the phase of the operation of fast-forwarding AV content reproduced from the first part to the position where the user stopped is omitted.

The content information generated by the content information data unit 14 will be described with reference to FIG.
Here, AV contents of C1, C2, and C3 are stored in the content storage unit 16. The content information data portion 14 is C1. mpg, C2. mpg, and C3. Create a folder for mpg. When the content information data unit 14 outputs the folder information via the network 3, it is described and transmitted in accordance with a description command defined by DLNA (Digital Living Network Alliance) guidelines. It is described having a DMS (Digital Media Server) function and a DMP (Digital Media Player) function defined by the DLNA guidelines. C1. The HTTP command for mpg is, for example, http://192.168.100.200:30001/video/C1. It is described as mpg. The AV content C1_w. mpg is, for example, http://192.168.100.200:300001/video/C1_w. It is described as mpg. These described HTTP commands are described in XML (eXtensible Markup Language) and transmitted together with the GET command and the POST command.

The seek position controller 23 will be described with reference to FIG.
In the figure, the AV content bit stream acquired from the content storage unit 16 by the content acquisition unit 22 is input to the AV packet detector 231. The AV packet detector 231 detects whether a packet constituting the bit stream is an audio packet or a video packet. The AV playback time difference detector 232 detects the time played by each of the audio packet and the video packet. The re-reproduction start position determiner 233 reproduces audio packets that are in the past for a few seconds with respect to the position of the AV content where the stop operation has been performed by the user and between the position where the stop operation has been performed from the past position. A past position where the time and the playback time of the video packet are substantially the same time is determined as the re-start position, that is, the transmission start position. The time code storage unit 234 stores a time code related to the transmission start position.

The re-start start position (transmission start position) will be described with reference to FIG.
FIG. 6A shows C1. This shows a state where the reproduction of the content of mpg is started from the reproduction start position and is reproduced up to the stop position. (B) shows a portion of the AV content displayed on the television 42 by the reproduction start and stop of (A). (C) shows a time portion displayed on the television 52 with a halftone dot when reproduction of the content of (A) is restarted. The reproduction restart position in (C) is restarted ahead of a stop time indicated by (B) for a predetermined time. Here, since the playback time of the audio packet and the playback time of the video packet existing between the playback restart position and the stop position of the AV content are set to be substantially the same time, the AV content shown in (C) In spite of the playback from the middle, the AV synchronization is accurately performed, and the latter half of the AV content is played back without causing any troubles such as a lip sync shift or a video frame shift.

The operation of the AV server device 1 when the remote controller 51 is operated will be described with reference to FIGS.
First, when the remote controller 51 on the TV 52 side is operated and the command control unit 13 receives a control command, the timer 24b of the timer unit 24 is in a counting state in S (step) 61, and the count value is, for example, 60 seconds. It is detected whether it is within a predetermined time. If it is within the predetermined value, the timer 24b is stopped in S81, the seek value is set to 0 in S82, and the process returns to S61. Whether the timer 24b does not count in S61, or if the coefficient value exceeds the predetermined value, the timer 24a counts in S62 and the counting time is within a predetermined time (for example, 10 seconds) Is detected. If detected, the timer 24a is stopped in S83, and the operation from S61 is repeated. If not detected, it is detected in S63 whether a control command related to the reproduction operation has been issued. If detected, the timers 24a and 24b are stopped in S64. In S65, the control command of the specified URL (Uniform Resource Locator) described from HTTP attached to the reproduction control command is analyzed. In S66, a seek position is set. When a designated URL is designated from each of a plurality of televisions, a seek position table is created for each television. In S67, the AV content portion designated from the content storage unit 16 is read.

If the reproduction operation is not detected in S63, the process is executed from B in FIG. In S71, it is detected whether an operation for the next reproduction has been performed. If detected, the operation data of the remote controller 51 is read in S72. After execution of S72 and after execution of S67, EOF (End of File) of the AV content is detected. If detected, the seek value of the URL is set to 0 in S74. If not detected, the reading position of the AV content read from the content storage unit 16 is updated to the position of the next reading unit. The AV content data acquired by the content acquisition unit 22 in S76 is sent to the television 52 via the server content communication unit 21, and the process returns to S61.
If the next reproduction operation is not detected in S71, it is detected in S85 whether a disconnection request has been made. When a disconnection request is made, the timer 24a starts counting in S86, and when the timer 24a counts a predetermined number, the timer 24b starts counting. The progress data generated by the disconnection request process is transferred to the server content communication unit 21 in S87, and the operation from S61 is repeated. If no disconnection request operation is detected in S85, it is detected in S88 whether a playback end operation has been performed. If not, the operation from S61 is repeated. If it is detected, the operation is terminated.

  Here, the timer unit 24 is provided with the timers 24a and 24b, and the time from when the user stops the operation until another television is operated and the content information is requested is described as 70 seconds, for example. The set time is a design matter, and a longer time may be set in the timer 24b. Further, especially when the number of users using the AV server system 10 is small, the counting control by the timer 24b may not be performed.

In the above, the AV server apparatus 1 that performs control for performing viewing of the AV content stored in the content storage unit 16 from the television 42 side to the middle and using the DLNA to perform the subsequent viewing from the television 52 side has been described. . Here, if the televisions 42 and 43 are connected to a network and can be controlled by, for example, DLNA, the AV server system 10 can be configured using televisions on the market.
Then, the AV server device 1 can be accessed from the televisions 42 and 43, and the content confirmation of the AV content stored in the content storage unit 16 and the update confirmation of the stored AV content can be performed. When the user connects from the television 42 or 43 to the AV server device 1, the user operates the remote controller 41 or 42 to perform a control command for confirming reception of the content replacement notification. If there is new AV content software, a holder for displaying the new software is newly provided in the AV content holder shown in FIG. 3, and for example, the AV content accumulated within two days is displayed as new content. You may do it.

As described above, according to the AV server device 1 shown in the present embodiment, a command indicating a reproduction request transmitted from one receiving terminal among the plurality of receiving terminals 42 and 52 is received by the command communication unit 12. During the period from when the command communication unit receives a command indicating a stop request transmitted from one receiving terminal, the playback AV content, which is AV content requested to be played from one receiving terminal, is read from the storage unit 16 and 1 Content distribution unit 21 that distributes to a reproduction receiving terminal that is one receiving terminal, and when a command indicating a stop request from the reproduction receiving terminal is received by the command communication unit, the reproduction AV content distributed from the content distribution unit A storage unit for storing a distribution stop position, a timer unit 24 for measuring an elapsed time since the distribution of the playback AV content is stopped, and a plurality of receiving terminals When a playback request for the same AV content as the playback AV content requested to be stopped from other receiving terminals other than the playback receiving terminal is made, the elapsed time being measured by the timer unit is within a predetermined time When the distribution stop position of the reproduction AV content stored in the storage unit 16 is set as the distribution start position of the same AV content, and the elapsed time being measured by the timer unit exceeds the predetermined time, the reproduction AV content is The seek position control unit 23 that sets the first position as the distribution start position of the same AV content and the distribution start position that is set by the seek position control unit as the distribution start position of the same AV content to be distributed to other receiving terminals And a control unit that controls the content distribution unit so that it is positioned, so that the conventional remote controller can be used as it is and the network The AV server device capable of reproducing while inheriting the reproduction of the AV content being watched among the plurality of television receivers to be continued can be realized.
Also, when a distribution request for the same AV content as the reproduction AV content requested to be stopped from another receiving terminal is made, if the elapsed time being measured by the timer unit is within a predetermined time, the same AV content In the case of having a seek position control unit that sets a distribution start position as a position a predetermined time before the distribution stop position of the playback AV content stored in the storage unit, viewing is performed among a plurality of television receivers. It is possible to realize an AV server apparatus that can ensure the AV synchronization from the time when the reproduction is resumed and can reproduce the AV content by inheriting the AV content.
