Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
Example 1
A digital television program comment and bullet screen system comprises a bullet screen generator, a multiplexer, a program comment server and a digital television network terminal (such as a set top box); and a digital television user internet terminal (such as a mobile phone, a tablet computer, etc.), and a system working principle diagram is shown in fig. 1.
The program comment server runs at the Internet cloud, creates program comment groups for specified digital television programs under the control of the front-end bullet screen generator, generates different entry websites for each program comment group, sends the entry websites to the bullet screen generator after a comment group of a certain program is created, and transmits the entry websites to the set top box through a multiplexed stream to be displayed in a two-dimensional code mode. And the program comment server also obtains program description information from the bullet screen generator, and packages and transmits the program description information and the entrance website to the program comment client. The program comment server receives and stores comments of programs from different comment clients (running on the user intelligent terminal), dynamically counts and sorts the comments of the programs according to factors such as hot degree, interaction quantity, updating time and the like, sends the hot comments to the bullet screen generator according to a certain rule, and transmits the hot comments to the set top box through a multiplexing stream to be displayed in a scroll bar mode.
And the bullet screen generator is responsible for encoding to generate a program bullet screen information stream. It obtains program description, program schedule (broadcast time, broadcast channel), and information whether to open the barrage from the outside (e.g., electronic program guide system). If a bullet screen is opened for a certain program, the bullet screen generator informs a program comment server to create a comment group for the program within a certain time before the program is played, acquires an entrance website of the program comment group and a bullet screen text containing popular comments from the program comment server, and converts the entrance website and the bullet screen text into a bullet screen information stream of the program; at a certain moment before each program supporting the bullet screen starts, until the program is broadcast, the bullet screen generator will continuously insert bullet screen information into the code stream of the program. Wherein the entrance address of the program comment group is fixed; the popular comments are dynamically updated.
After the bullet screen information stream and the digital television program code stream generated by the bullet screen generator are multiplexed together by the multiplexer, the bullet screen information stream and the digital television program code stream are transmitted to a digital television terminal (set top box) through a digital television broadcasting network.
The set top box receives the digital television broadcast signals, can synchronously display barrage information containing program popular comments while broadcasting the digital television programs, and directly superimposes the contained information on the video for rolling display. The entrance address of the program comment group can be displayed in a two-dimensional code form after a user presses a special key of the remote controller according to the requirement.
The user uses a program comment client (an APP on a mobile phone or a tablet computer) to participate in program comment. The program comment client can participate in a certain program comment group through two ways: 1) after creating a comment group of a certain program, the program comment server pushes a message notification to the mobile phone, and a user clicks a link in the notification to start a program comment client to enter a comment website to directly participate in the program discussion; 2) and using the program comment client, generating and displaying a two-dimensional code on the television by the code scanning set top box, and participating in the comment of the program according to a certain program discussion group entry website contained in the two-dimensional code. Through the program comment client, a user can make a comment for a certain program, or perform operations such as follow-up comment and praise on comments of other users; the information is sent to the program review service end for processing and storage.
Example 2
The operator deploys a bullet screen generator at the front end of the digital tv, which may be part of the operator's Business Operations Support System (BOSS) or Conditional Access System (CAS). The BOSS or CAS system including the function of the bullet screen generator may receive the bullet screen text and the website information of the program review group entry from the video forum website (program review server), generate the bullet screen text message and the program review website information accordingly, and send the bullet screen text message and the program review website information to the set top box through the digital television broadcast network for display. The system deployment architecture is shown in fig. 2. The bullet screen message aiming at a certain program can only be inserted into the bullet screen code stream of the digital television channel where the program is located. The program comment server is located at the high in the clouds, and it realizes the communication with barrage generator through the internet. The set-top box software is upgraded in advance to support the bullet screen receiving and displaying functions. The set-top box user also needs to download the APP containing the program comment client function module. The bullet screen information processing flow comprises the following steps:
the operator decides to open the barrage for a certain program of a certain channel, and the operation and maintenance personnel thereof perform program comment opening operation for the program on the management interface of the barrage generator. The bullet screen generator sends the program information and the broadcasting time to a program comment server, the program comment server creates a discussion group for the program and transmits the entrance website to the bullet screen generator; when a user has comments about a program, the program comment server sends the comments about the program (including the text, the author, the occurrence time, the interactive heat and the like of each comment) to the bullet screen generator in real time.
At a certain time before the program starts to be broadcast, the bullet screen generator starts to insert bullet screen information flow into the channel of the program; as previously mentioned, including the program discussion group entry web address and the real-time barrage message.
The set-top box receives the real-time barrage message and displays the barrage message On a television Screen in an On-Screen Display (OSD) mode according to the requirement; the real-time bullet screen message contains a comment text, a comment author, release time and necessary control parameters (such as bullet screen rolling direction, speed, proportion of the bullet screen and the like), and the set top box displays all the bullet screen texts in a rolling mode according to the requirements of the control parameters.
And after the set top box receives and detects the program comment entrance website information, reminding the user in a certain mode on a television screen. For example, a special prompt icon is displayed, and "a program being broadcast is being commented, and you can participate in the discussion by pressing a remote control button". At this time, if the user presses the remote control key, the set top box converts the website of the program comment group entry into a two-dimensional code and displays the two-dimensional code on the screen, and prompts 'turn on your mobile phone APP to scan the two-dimensional code to participate in discussion'.
The set top box user opens the APP to scan the two-dimensional code, then the APP automatically starts the program comment client function and enters the comment group of the program; through the APP of the program comment client, a user can perform operations such as program comment, review of other users or comment on a net friend. The subscriber can also actively start the APP of the program comment client, and then select any program comment group with opened comments to add comments; but the two-dimensional code can be scanned to directly enter the comment group of the program currently watched.
If the user makes a new comment, or a comment that has been made is highly reviewed by a net friend, the comment he (she) made will be displayed on the television screen in a pop-up manner together with comments of others.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included therein.
