The set-top box is an IPTV terminal device placed in the home of the user. The set-top box is accessed to the network by ADSL or LAN mode, the user side is connected with the TV set, and it has standardized general input and output interface. Bidirectional symmetric or asymmetric communication traffic is supported. It undertakes the functions of forwarding information from network to user or from user to network, and media format conversion to transmit media format to display device. The user can obtain related services from the operator IPTV system through the set-top box. The program recording of the live channel is used as a basic function of the IPTV service, is also an advantage function compared with the traditional television, is favored by a large number of users, and is also valued by operators and equipment vendors.

step 202: after IPTV terminal equipment receives a first bandwidth updating notification sent by other IPTV terminal equipment in the home network, updating a local bandwidth use list according to the first bandwidth updating notification;
step 203: before an IPTV terminal device starts an IPTV service needing to occupy bandwidth, acquiring the bandwidth needed by the IPTV service;
step 204: the IPTV terminal equipment obtains the current residual bandwidth of the home network according to the local bandwidth use list;
step 205: the IPTV terminal device determines whether the current remaining bandwidth of the home network meets the bandwidth required by the IPTV service, and if yes, goes to step 206; otherwise, go to step 207;
step 206: the bandwidth application of the IPTV service is successful, and the IPTV terminal equipment updates a bandwidth use list; and transmits a first bandwidth update notification for notifying that the same update operation is performed to other IPTV terminal devices in the home network.
Step 207: the IPTV service bandwidth application fails and is not started.
As can be seen, in this embodiment, all IPTV terminal devices in the home network may locally maintain a bandwidth usage list including the usage conditions of the home network bandwidth; and then when the IPTV service occupying bandwidth resources needs to be started on the IPTV terminal equipment, obtaining the current residual bandwidth of the home network according to a locally maintained bandwidth use list, and then judging whether the residual bandwidth meets the bandwidth required by the TPTV service, if so, the application is successful, otherwise, the application is failed, and the service is not started. Therefore, the bandwidth control method in the embodiment has at least the following advantages:
1. the bandwidth use list of the home network is dynamically maintained on each IPTV terminal device in the home network, so that the application of IPTV service bandwidth can be realized locally on each IPTV terminal device without information interaction among the devices, the efficiency of bandwidth resource management and control can be improved, and the time delay of the information interaction among the devices can be avoided.
2. The IPTV terminal in this embodiment may be an STB set-top box, a DVR set-top box, or a mobile phone, a PAD, or other mobile terminals, so that when the mobile terminal accesses the home network, the above bandwidth resource control process may also be locally implemented, so that no bandwidth resource conflict occurs when playing a video on the mobile terminal, and a user may directly play a video on the mobile terminal, which may greatly improve the satisfaction degree of user experience;
3. the bandwidth control in this embodiment is controlled by taking an IPTV service as a unit, that is, based on the bandwidth control of the service, and when the service is turned on or turned off, the current bandwidth resource condition is correspondingly updated, so that the bandwidth resource of the home network can be maximally utilized.
Of course, in this embodiment, one of the IPTV terminal devices in the home network may be selected as the master device, and the others may be all used as the slave devices; then, only a bandwidth use list is dynamically maintained on the master device, and when the IPTV service occupying the bandwidth needs to be started on other slave devices, a bandwidth application request can be sent to the master device, wherein the request comprises the bandwidth required by the IPTV service; after receiving the request, the master device locally judges whether the residual bandwidth resources are met, and feeds back an application result to the slave device. For example, the master DVR set top box in fig. 1 may be provided as a master device, and the STB set top box 1, the STB set top box 2, the master DVR set top box, other independent DVR set top boxes n, and a mobile phone may be used as a slave device.
Referring to fig. 3, based on fig. 2, the bandwidth control method in this embodiment further includes:
step 208: when the IPTV service is closed, the IPTV terminal equipment releases the bandwidth occupied by the IPTV service and updates a bandwidth use list;
step 209: the IPTV terminal equipment sends a second bandwidth updating notice for notifying the same updating to other IPTV terminal equipment in the home network;
step 210: and the IPTV terminal receiving the second bandwidth updating notice updates the local bandwidth use list.
It should be noted that the content format of the bandwidth usage list storage in the present embodiment may include any one of the following formats:
1. directly storing the currently occupied total bandwidth value of the home network or the currently remaining total bandwidth value of the home network;
2. storing currently-started IPTV service information (e.g. URL (Uniform resource Locator) of each IPTV service) on each IPTV terminal device in the home network, wherein the IPTV service information comprises bandwidth occupied by each IPTV service;
3. in addition to the above-mentioned form 2, IPTV terminal device information (e.g., terminal ID) where each IPTV service is located is further stored; so as to facilitate the subsequent regulation and control management of the IPTV service.
In this embodiment, the IPTV terminal device may specifically obtain the bandwidth occupied by the IPTV service through the URL of the IPTV service.
In this embodiment, when the IPTV terminal device sends a bandwidth update notification to other interrupt devices in the home network, the bandwidth update notification may include a bandwidth usage list updated by the IPTV terminal device, and the other IPTV terminal devices receive the notification and then directly replace the local bandwidth usage list; the bandwidth update notification may also include bandwidth change information (e.g., how much bandwidth is occupied by which IPTV service is turned on, or how much bandwidth is released by which IPTV service is turned off), and after receiving the notification, the other IPTV terminal devices correspondingly update the local bandwidth usage list according to the change information.
In this embodiment, when the bandwidth usage of the home network reaches a critical upper limit, and at this time, when a plurality of IPTV terminals (e.g., mobile phones and DVR set top boxes) simultaneously apply for the bandwidth, the situation that the respective IPTV terminals apply for the bandwidth successfully, but the actual total bandwidth exceeds the limit may occur. Therefore, in this embodiment, in order to further realize effective regulation and control after the situation occurs, one of the IPTV terminal devices in the home network may be selected as a master terminal device, and the other IPTV terminal devices may be used as slave terminal devices; at this time, the bandwidth usage list stores currently-started IPTV service information, the bandwidth occupied by each IPTV service, and IPTV terminal device information where each IPTV service is located. After receiving the update notification of other slave terminal devices, the master terminal device correspondingly updates the local bandwidth utilization list, and then sends an instruction for closing the IPTV service to the IPTV terminal device where at least one IPTV service in the bandwidth utilization list is located according to a preset principle when the total bandwidth occupied by the IPTV service in the bandwidth utilization list is greater than or equal to the total bandwidth of the home network is counted, so that the IPTV service releases the occupied bandwidth.
The preset principle in this embodiment may be to close the newly opened IPTV service according to a time sequence; or randomly selecting at least one from the currently opened IPTV service to close; or selecting the service with the lowest priority to close according to the priority of each IPTV service; or directly closing the service occupying the largest or the smallest bandwidth in the IPTV service which is opened currently, and the like.
In this embodiment, when the IPTV terminal device serving as the master terminal device fails (e.g., is powered off), one IPTV terminal device may be additionally selected as the master terminal device from the remaining slave interrupt devices. The selection mode can be that one of the rest slave devices is directly selected randomly as the main terminal device; or selecting one with the longest online time as the main terminal device according to the online time of each slave terminal device; or different types of IPTV terminal equipment are set to have different priorities, and then one terminal equipment with the highest priority is selected as a main terminal equipment, and the like.

Meanwhile, the DVR set top box can adopt the same resource usage table when the capacity of the DVR set top box is processed and the bandwidth conflict is managed, and one table does not need to be maintained in each process, so that the abnormal situation caused by the inconsistency of a plurality of tables is avoided.
Example three:
for a better understanding of the present invention, the present application is further described below with reference to a specific home network as an example.
Referring to fig. 7, the home network in this embodiment includes a master DVR set top box (DVR HUB), a standalone DVR set top box (Non DVR, referred to herein as a slave DVR set top box), and a mobile terminal, such as a mobile phone. Wherein the main DVR set-top box is a main terminal device in the home network; the slave DVR set-top box and the mobile terminal are slave devices. The main DVR set-top box and the secondary DVR set-top box are both provided with an IPTV component and a DVR component, and the DVR component is provided with various functional modules (generally called as bandwidth conflict management modules) for recording management and realizing bandwidth resource management in the second embodiment; meanwhile, the system is also provided with a UI playing/recording module; the mobile terminal has a UI browsing program information/push/video playing module, and also has various functional modules (collectively referred to as bandwidth conflict management modules) for implementing bandwidth resource management as shown in the second embodiment. Based on the home network structure, the bandwidth resource management process is as follows:
the bandwidth conflict management module in the main DVR set top box is responsible for uniformly managing resource usage of the whole family bandwidth and processing the capacity and bandwidth application request of the local machine, the bandwidth conflict management module in the slave DVR set top box is responsible for updating a family bandwidth usage list and processing the bandwidth request of the local machine, the bandwidth conflict management module on the mobile terminal is used as a dynamic lib library and is provided for a UI module of the mobile terminal and is responsible for updating the bandwidth usage list and processing the local bandwidth application request, and the specific details are as follows:
when TPTV service needs to apply for bandwidth in a main DVR set-top box, a bandwidth conflict management module in the main DVR set-top box judges whether conflict exists according to a locally maintained bandwidth use list, namely whether the residual bandwidth of the current home network meets the requirement of the IPTV service or not is judged, if the residual bandwidth meets the requirement, the bandwidth application is successful, the local bandwidth list is updated, and new bandwidth information is multicast in the home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
When IPTV service needs to apply for bandwidth from a DVR set top box, judging whether the bandwidth conflicts according to a locally maintained bandwidth use list from a bandwidth conflict management module in the DVR set top box, namely judging whether the residual bandwidth of the current home network meets the requirement of the IPTV service, if so, successfully applying the bandwidth, updating the local bandwidth list, and multicasting new bandwidth information in the home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
When the IPTV service needs to apply for the bandwidth on the mobile terminal, a bandwidth conflict management module on the mobile terminal judges whether the bandwidth conflicts or not according to a locally maintained bandwidth use list, namely whether the residual bandwidth of the current home network meets the requirement of the IPTV service or not is judged, if the residual bandwidth meets the requirement, the bandwidth application is successful, the local bandwidth list is updated, and new bandwidth information is multicast in the home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
Correspondingly, when the IPTV service is closed and the bandwidth resource is released on the main DVR set top box, the bandwidth conflict management module on the main DVR set top box updates a local bandwidth use list and multicasts the released bandwidth in the home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
When the IPTV service is closed and the bandwidth resource is released from the DVR set top box, updating a local bandwidth use list from a bandwidth conflict management module on the DVR set top box, and multicasting the released bandwidth in a home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
When the IPTV service is closed and the bandwidth resource is released on the mobile terminal, the bandwidth conflict management module on the mobile terminal updates a local bandwidth use list and multicasts the released bandwidth in the home network; and after receiving the bandwidth information, the other terminals update the local bandwidth list.
In this embodiment, when multicasting the bandwidth information, the sequence of resource application/release can be distinguished according to the timestamp in the UTC format.
In this embodiment, the updated bandwidth information and the key information recorded in the bandwidth usage list may include a URL of a service resource, so as to manage the home bandwidth;
when the use of the household bandwidth reaches the critical upper limit, and the master DVR set-top box, the slave DVR set-top box or the mobile terminal respectively simultaneously apply for the bandwidth resources, the situation that the respective applications are successful but the actual total bandwidth exceeds the limit may occur, after the master DVR set-top box receives the update notification of the newly added bandwidth from the DVR set-top box or the mobile terminal, the local bandwidth use list is correspondingly updated, and when the actual use is counted and found to exceed the limit, the occupation of the TPTV service resources with low priority can be cancelled according to the priority used by the current IPTV services, and the corresponding terminal is notified to release the bandwidth resources, so that the IPTV services are stopped (for example, the playing of videos is stopped); when the terminal stops the service because the resource is seized, the terminal can report an event notification UI to prompt a user to stop playing in a confliction manner.
As can be seen, in the present embodiment, the bandwidth control of the master terminal device and the bandwidth control of the slave terminal device are the same in status when the application and release of the home bandwidth are processed, and there is no master control end. Only when the bandwidth exceeds the limit, the bandwidth is uniformly processed by the bandwidth control module of the main terminal equipment;
the process is based on the bandwidth control of the service in the home network, and the home bandwidth control is carried out according to the URL of the service resource; when a service is applied or released, the bandwidth lists of all terminal devices in a family are updated in real time, so that the family bandwidth is ensured to be utilized to the maximum extent, and the problems that certain device is idle and the bandwidth utilization rate is low when the terminal is controlled are solved;
