Description

EPG page play control method and set-top box
Technical Field
The invention belongs to the technical field of media playing terminals, and particularly relates to an EPG page playing control method and a set top box.
Background
Various service indexes and navigation provided by the IPTV set-top box are accomplished through an EPG (Electrical Program Guide) system. The EPG is actually a portal system of IPTV (Interactive personal television), and the interface of the EPG system is similar to a WEB page: the EPG interface provides various menus, buttons, links and other components which can be directly clicked by a user when the user selects different programs, wherein the components comprise various dynamic or static multimedia contents. Currently, the EPG mainly adopts a B/S (Browser/Server) architecture, a Server terminal deploys various resources, and a terminal requests various EPG resources of the Server terminal through HTTP. The set top box renders and displays the EPG interface through the built-in browser, and finally provides a two-dimensional interface display effect for a user.
However, the display resolution of the current EPG interface is mainly focused on 720P and 1080P systems, and the ultra-high definition systems such as 4K are not commercially available for a while. For an EPG with rich rendering effects, such as waterfall flow, a set-top box terminal is often required to have higher CPU processing capability. Aiming at showing multiple ultra-high definition bitmaps on some EPG interfaces, the set-top box terminal is supposed to consume more memory resources in the processes of decoding the multiple bitmaps and switching the whole EPG interface screen. The tension of terminal memory allocation and scheduling often directly causes the user to pause the remote key operation. In addition, if the EPG server has an abnormal operation load, a TCP link requested by a terminal HTTP (HyperText Transfer Protocol) is overtime or fails, and at this time, the set-top box cannot normally display the EPG interface. The service index and navigation provided by the IPTV have no way to be presented to the user, and the user experience is necessarily reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The streaming media playing data in the current IPTV system is basically in a package format based on the TS code stream. Service Information (SI) data in these streams may help a user select information of a desired service or event from the TS stream, so that the set-top terminal can automatically set the selected service by parsing the SI data. The service information in GB/T17975.1-2000 is called Program Specific Information (PSI) and is divided into one or several segments to be represented and then inserted into TS packets. The PID value and table identifier (table _ id) of TS packet for transmitting service information segment are defined in turn in the specification, and the reserved PID:0x 0016-0x001D was used as an extension. Table _ id 0x80-0xFE is defined for the user to extend. By the method, a PID (proportion integration differentiation) in PSI/SI (program specific information/service information) information, namely 0x0016 is a navigation information table of an EPG interface, and each TS stream is attached with the navigation information table with the PID of 0x0016 (it is to be noted that the PID value of the navigation information table can be arbitrarily selected from 0x0016-0x001D, and the table _ id value can be arbitrarily selected from 0x80-0 xFE). When the TS stream is played to show the EPG interface, the navigation information table can assist a built-in browser module of the set-top box to perform focus drawing, OSD effect superposition and the like in a set area.
The navigation information table of the EPG interface corresponds to PID 0x0016, and table _ id is: 0x 80. The table mainly functions to generate a two-dimensional navigation information table according to all component contents of the EPG interface. And when the set top box plays and displays the EPG interface, the two-dimensional navigation information table is analyzed to obtain the coordinate values of all the components of the EPG interface, the sizes of the components and the playing addresses of the components needing to be subjected to link jumping. The set-top box browser module can realize focus movement navigation, OSD layer effect superposition, EPG personalized theme setting and the like according to the parameter information.
And when the browser receives the confirmation key, skipping and refreshing display of the EPG interface are required. And the set-top box performs video playing switching by using the playing address of the link jump in the navigation information table, and plays another TS code stream to display the content of the EPG interface after the jump. And then repeating the playing and displaying of the EPG page: and performing content drawing such as focus display, navigation, OSD effect superposition and the like on the EPG interface.
All the link jumps of different EPG interfaces can be regarded as media stream playing of different addresses.
The media stream may support 4K playback. The set-top box can realize the display of the 4K resolution EPG interface by playing the 4K video stream, and can automatically zoom and adjust according to the difference of the HDMI output resolutions of the television.
Example 1
As shown in fig. 1, the present invention provides a method for controlling EPG page playing, including:
s1, making TS streams according to the component typesetting layout of each EPG page, wherein each EPG page displayed on a screen needs to correspond to a single TS stream, and each TS stream contains a navigation information table;
the EPG system needs to make TS code streams of the image-text channels in advance according to the component layout of each interface. These separate TS streams may contain only video information and no audio information, or the content of the video information may contain only all the component elements of the corresponding EPG interface. The video information resolution, coding format, code rate, frame rate and other characteristic values in the code stream and the number of bytes of the finally generated code stream can be flexibly configured in the background of the server according to actual needs.
Each EPG page presented on the television screen needs to correspond to a separate TS stream. And one or several navigation information tables in the present invention need to be inserted into these separate TS streams. In systems that consider random access, it is proposed to repeat the transmission of the navigation information table several times, even if the structure does not change. For the navigation information table marked with the same PID and table _ id values, the minimum time interval between the last byte of the segment and the first byte of the next segment is 25 milliseconds.
Specifically, the navigation information table at least includes:
component element X coordinate: marking the offset pixel of the abscissa of the component in the EPG interface, and corresponding to the offset value of the vertex at the upper left corner of the current EPG interface;
component element Y coordinate: marking the offset pixel of the vertical coordinate of the component in the EPG interface, and corresponding to the offset value of the vertex at the upper left corner of the EPG interface;
width of the assembly: marking the width pixel values that the component needs to display to occupy;
height of the assembly: marking the height pixel value that the component needs to display to occupy;
labeling of each component of the EPG interface: marking the serial number of the current component;
EPG interface jump descriptor: marking a streaming media address which needs to be switched when the set top box carries out full-screen skipping of an EPG page;
the navigation information table is further described in detail in embodiment 2.
S2, the set-top box plays the TS stream and displays the EPG interface, and the navigation information table contained in the TS stream is analyzed to obtain the coordinate value of each component in the EPG interface, the size of the component and the playing address of the component needing to be linked and jumped;
s3, the set top box draws a highlight focus icon of the default component on the OSD layer according to the parameter information obtained by analyzing the navigation information table;
specifically, after the streaming media video is successfully played, the set top box draws a highlight focus icon of the default component on the OSD layer according to the first component element description information in the parsed navigation information table.
S4, the set top box receives control operation of a user, and dynamic drawing of the EPG interface focus icon is realized according to parameter information obtained by analyzing the navigation information table;
specifically, when the set top box receives that a user performs focus movement on a current EPG interface through a remote controller key, the set top box firstly destroys a highlight focus icon currently displayed on an OSD layer, and then obtains a current _ index of a current component according to the offset number of focus movement of an abscissa and an ordinate;
the set top box describes and matches information corresponding to the lower label according to the information obtained by the lower label of the current component from the navigation information table, so that the coordinate position and the area size of the highlight focus to be drawn can be obtained, and a highlight focus icon is drawn on an OSD layer;
and S5, the set-top box receives the page switching operation of the user to jump the EPG page.
Specifically, when the set-top box receives a jump instruction, jumping and refreshing display of the EPG interface are needed, video playing switching is performed by using a playing address of link jump in the navigation information table segment, and another TS code stream is played to display the content of the jumped EPG interface.
Example 2
The embodiment of the invention describes the navigation information table in detail, and the EPG interface navigation information table provides the coordinate, the size and the link configuration information of each component element in the EPG page displayed currently. "navigation information" is defined as a set of descriptions of page components and may span across different networks. Table 1 is a semantic description of one implementation of the navigation information table of the present invention. Of course, for those skilled in the art, there are semantic descriptions of other implementations based on the heuristic of this table, which are not described herein again.
TABLE 1 semantic description of navigation information tables
Figure BDA0002576951710000091
Figure BDA0002576951710000101
Specifically, the definition of each field in the navigation information table is described as follows:
table identifier table _ id 0x80, and table _ id of all navigation information table segments is 0x 80.
The segment syntax indicator section syntax indicator 1 bit field, shall be set to "1".
Segment length 12 bit field, first two locations "00". It indicates the byte length of the segment starting from the next byte of the field and contains the CRC. Since the link jump address of a certain component element will be described in the navigation information table, the length of the navigation information table segment needs to be extended from 1024 bytes to 4096 bytes.
Version _ number 5 bit field. The version number of the sub-table is identified. When the information contained in the sub-table changes, version _ number is incremented by 1. When the value increases to 31, it is reset to 0.
Current next indicator 1 bit indicator is the current subsequent indicator. When set to "1," this indicates that the current sub-table is being used. When it is set to "0", it indicates that the passed sub-table has not been used, and it is the next sub-table to be used.
Segment number 8-bit field. The section _ number of the first section in the sub-table is denoted as "0 x 00". 1 is added every section _ number added with the same table _ id.
Last segment number 8-bit field, which indicates the segment number of the last segment (i.e., the segment with the largest segment number) of the sub-table to which it belongs.
Component element X coordinate pixel _ left 16 bit field marking the offset pixel of the abscissa of the component in the EPG interface. Offset value relative to the top left vertex of the current EPG interface.
Component element Y coordinate pixel _ top 16 bit field marking the offset pixel of the vertical coordinate of the component in the EPG interface. Offset value relative to the top left corner vertex of the EPG interface.
The component width pixel width is a 16-bit field that marks the width pixel value that the component needs to display to occupy.
Component height pixel height a 16-bit field marks the height pixel value that the component needs to display to occupy.
Each element mark index label focus _ index of EPG interface is 8 bit field, marking the serial number of current element. The labels are counted by default starting with "0".
An EPG interface jump descriptor link _ url _ descriptor is a 128-bit field, and marks the streaming media address which needs to be switched when the set top box performs full-screen jump of an EPG page.
CRC _32:32 bit field: the CRC value is included and after processing the entire segment, the register output of the defined CRC decoder is zero.
Example 3
The embodiment of the invention provides an EPG page playing control method, which comprises the following steps:
and powering on the terminal, and starting the IPTV platform authentication.
After the set-top box passes the platform authentication, the authentication platform issues the streaming media address of the EPG home page.
The set-top box attempts video playing using the streaming media address and parses the component element description information in the navigation information table in the TS stream.
And after the set top box successfully plays the streaming media video, drawing a highlight focus icon of a default component on an OSD layer according to the first component element description information in the analyzed navigation information table.
When the set top box receives that a user carries out focus movement on the current EPG interface through a remote controller key, the set top box firstly destroys a highlighted focus icon currently displayed on an OSD layer. Then the current component current _ index is obtained according to the shift number of the focus movement of the abscissa and the ordinate.
The set top box describes and matches the focus _ index according to the information obtained from the navigation information table by the current _ index, so that the coordinate position and the area size (component width and height pixels) of the highlight focus to be drawn can be obtained, and the highlight focus icon is drawn on the OSD layer by self.
When a user determines that the key needs to perform EPG interface skip or full screen switching through a remote controller, the set top box matches a new streaming media URL described in a link _ URL _ descriptor according to the focus _ index, and tries video playing by using a new streaming media address. And because the set top box switches the TS code stream, the default drawing of the highlight focus is repeated at the moment.
Example 4
As shown in fig. 2, an embodiment of the present invention provides a method for displaying a broadcast from start-up to an EPG home page, including:
s101, the set-top box is powered on and started to carry out IPTV platform authentication;
s102, after the set-top box is successfully authenticated, the set-top box does not actively request the EPG home page any more, and the authentication platform issues the streaming media address of the EPG home page;

Example 5
As shown in fig. 3, an embodiment of the present invention provides a method for a user to perform focus movement navigation switching on an EPG interface through a remote controller, when the user performs focus movement navigation on the EPG interface through a direction key of the remote controller, playing of a video stream is not affected by any key, and a set-top box browser module re-acquires coordinate values and a display area, where a highlight focus needs to be drawn, according to a horizontal and vertical coordinate offset of a two-dimensional table corresponding to the EPG interface. When a user determines that the EPG interface skip occurs when a key is selected by a user through a remote controller or the EPG interface is switched on a full screen, the set top box player module needs to play the corresponding TS streaming media again, and informs the browser module to redraw the default highlight focus icon.
The specific processing steps are illustrated as follows:
s201, a user presses a key to trigger the highlight focus of an EPG interface to move, and a browser module automatically destroys a highlight icon displayed on an OSD layer at first;
s202, the browser recalculates the subscript number current _ index of the component needing to display the highlight focus according to the information of the up, down, left and right direction keys. For example, when the user presses the right key h times and the lower key j times in succession, for the initial state of the first component element of the current EPG interface with the default highlight focus at the upper left corner, current _ index is 0+ j (m-1) + h (n-1);
s203, the browser describes the information matched with the corresponding lower label according to the information obtained from the navigation information table by the current _ index value of the current component lower label (specifically, finding the matched focus _ index in the structMap structure);
s204, the browser redraws the highlight focus icon on the OSD layer according to the member parameter of the structMap [ current _ index ].
If the user presses the decision key to perform jumping or full-screen switching of the EPG page, the set-top box immediately executes the step S201 first, and destroys the highlight focus icon of the OSD layer. And then re-executes steps S103-S108 in the flow of fig. 1. The difference with the EPG home page displayed by the set-top box starting process is that: and the streaming media address of the EPG page required to be displayed in the starting process is automatically issued by the authentication platform. The browser module does not make any comparison. The address causing EPG page jump selected by the user service is obtained by the set-top box browser module from the link _ url _ descriptor field in the structMap structure information according to the current _ index of the current component.
