Abstract
Description
The present invention relates, for example, to an apparatus and method for controlling content trick play in a digital device that downloads and reproduces various types of content data provided by a content providing server in real time.
A commonly used video on demand (VOD) service, also known as an on-demand video service, for example, allows a large number of users from a central Contents Provider Server via a television or computer screen. It is a network content providing service for selecting a VOD title such as a provided movie and allowing viewing in real time.
The V-audio service may be used for various network services such as ordering a movie transmitted digitally, watching educational video, and video conferencing, and pausing a user while watching a video. It provides various functions such as slow speed or repeated viewing.
For example, when a user selects a VOD title such as a movie and watches in real time, when a user requests a forward jump operation or a backward jump operation, the content providing server downloads in real time. The transmission of the content data is paused.
Then, after jumping for a predetermined time interval or jumping to a recording position set as a search point in advance, content data is read and transmitted from the position. When the same jump operation occurs, a problem arises in that the user must temporarily wait.
The present invention, for example, in a variety of types of digital devices, such as a network BD-Player, if a certain amount of content data downloaded from the content providing server is buffered, while performing a decoding operation, during the content An apparatus and method for controlling content trick play for receiving a search point data through an interface with a providing server to more quickly process a trick play of a jump action requested by a user. It is to provide.
The content trick play control method according to the present invention performs a decoding operation when a predetermined amount of content data downloaded from a content providing server is buffered, and while performing the decoding operation, performs an interface with the content providing server. Requesting and receiving search point data at a predetermined time interval; Storing and storing the received search point data in storage, and generating and recording search table information for accessing the search point data; And retrieving the search table information and immediately reproducing any one search point data stored in the storage when a jump operation is requested while reproducing the content data.
In the search table information, any one or more of each search point number, a reproduction time, and address information in the storage in which the search point data is recorded are stored and managed in the form of a lookup table.
In addition, in the
In the third step, if a backward jump operation is requested while the content data is being played back, after confirming the playback time of the content data at the time, the search point data of the nearest previous playback time is immediately played. ,
In addition, in
In addition, the content trick play control apparatus according to the present invention, communication means for communication with the content providing server; Buffering means for temporarily storing content data downloaded from said content providing server; Decoding means for decoding if a predetermined amount of content data is temporarily stored in the buffering means; And while performing the decoding operation, request and receive search point data at a predetermined time interval through an interface with the content providing server, store the search point data in storage, and access search table information for accessing the search point data. And a control means for retrieving the search table information and immediately reproducing any one search point data stored in the storage when a jump operation is requested while generating, recording and managing the content data. Features,
In the search table information, any one or more of each search point number, a reproduction time, and address information in the storage in which the search point data is recorded are stored and managed in the form of a lookup table.
In addition, the control means, if the forward jump operation is requested while playing the content data, after confirming the playback time of the content data at that time, characterized in that for immediately reproducing the search point data of the next subsequent playback time,
In addition, when the backward jump operation is requested while the content data is being reproduced, the control means checks the reproduction time of the content data at that time, and immediately reproduces the search point data of the nearest previous reproduction time. ,
Further, the control means immediately reproduces the search point data, and during the reproducing operation, requests and receives and buffers content data thereafter based on the playback time of the search point data, and then The playback function is characterized in that the playback is performed following the search point data.
The apparatus and method for controlling content trick play according to the present invention is, for example, decoding various amounts of content data downloaded from a content providing server in various types of digital devices such as a network BD-Player, and the like. In the meantime, a search table for receiving and retrieving search point data at a predetermined time interval through an interface with a content providing server, storing the data in storage, and accessing the search point data In addition to generating and recording information, when a jump operation is requested while reproducing the content data, the search table information is searched to immediately reproduce any search point data stored in the storage, and By requesting and receiving subsequent content data and connecting and playing it, It is possible to process a trick play of a jump operation requested by a user who receives and watches contents such as an audio title in real time, thereby minimizing user waiting time.
Hereinafter, exemplary embodiments of a content trick play control device and method according to the present invention will be described in detail with reference to the accompanying drawings.
First, the apparatus and method for controlling content trick play according to the present invention can be applied to various types of digital devices equipped with a network function. For example, the
Meanwhile, the
In addition, the
The
For example, as shown in FIG. 2, the content data stream provided by the
In the
In the
Meanwhile, a buffering flag indicating whether the corresponding search point data is stored in the storage may be additionally recorded in the search table information, and the search point data may be, for example, 1 minute each. Content data corresponding to 5 seconds on the basis of the interval, and associated with the address information in the search table information.
In the
3 is a flowchart illustrating an embodiment of a method for controlling a content trick play according to the present invention. For example, the
On the other hand, when the predetermined amount of content data is buffered in the
Then, as described above with reference to FIG. 2, the search point data received from the content providing server is stored in the
For example, while receiving the first to third search point data P1 to P3 and storing the same in the storage, a predetermined ratio (eg, 50%) of content data buffered in the
If it is determined that the buffering of the content data is necessary as described above (S14), the interface with the
On the other hand, in the
For example, as shown in FIG. 4, when a forward jump operation is requested while reproducing content data corresponding to a middle portion of the first search point P1 and the second search point P2, In the
The second search point data stored in the
In addition, the content data after the second search point received through the above process is buffered in the
On the other hand, in the
The third search point data stored in the
In addition, the content data after the third search point received through the above process is buffered in the
And, until the end of playback is requested (S20), the above-described trick play (Trick Play) of the jump operation is performed, so that the user who received and watched the content such as the V-audio title in real time request of the jump operation The trick play can be processed more quickly, without user waiting time.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. , Alteration, substitution, addition, or the like.
