It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a channel playing method according to an embodiment of the present invention, which is applicable to a situation during channel playing or channel switching. The method may be applied to control a playback server, and is executed by a channel playback apparatus, which may be implemented in software and/or hardware, for example, the channel playback apparatus may be configured in a computer device. As shown in fig. 1, the method includes:
s110, receiving a channel playing request initiated by the mobile terminal, and determining a device identifier corresponding to the channel playing request according to the channel playing request.
At present, the mode of broadcasting program data to a set-top box generally is as follows: the main server of the broadcast and television transmits program data to each cell through optical fibers, the sub-servers of each cell modulate television programs through the modems and then broadcast the television programs to the cell, and the set-top box locks frequency points of channels to be played through adjusting the tuner and receives the program data corresponding to the frequency points of the channels to be played. In this embodiment, a method for broadcasting program data according to an application is provided, which considers that a large number of unidirectional set-top boxes exist in the existing set-top box equipment, and therefore direct communication cannot be achieved, and other technical means, such as a mobile terminal, are required to achieve the purpose. In this embodiment, when a channel playing request sent by a set-top box through a mobile terminal is received, program data corresponding to the channel playing request is played in a preset frequency point.
Optionally, a play control server may be set in the cell server, and receive a channel play request initiated by the user through the mobile terminal through the play control server, and play the program according to the received channel play request.
In this embodiment, the channel playing request sent by the mobile terminal and received by the playing control server includes the device identifier corresponding to the set-top box, and the device identifier and the channel identifier included in the channel playing request are obtained by analyzing the channel playing request.
Illustratively, when a user needs to switch a channel, the user may browse an Electronic Program Guide (EPG) through the mobile terminal and select a Program to be played, after the user selects the Program, the mobile terminal generates a channel playing request according to a Program identifier selected by the user and an equipment identifier of the set-top box, and sends the generated channel playing request to the control playing server, and after the control playing server receives the channel playing request initiated by the mobile terminal, the control playing server obtains the equipment identifier and the channel identifier of the set-top box included in the channel playing request by analyzing the received channel playing request.
And S120, matching the equipment identifier with a preset frequency point distribution list, and determining a broadcast channel corresponding to the equipment identifier.
In this embodiment, a frequency point allocation list is preset, fixed frequency points are allocated to each set top box device, and corresponding program data is broadcast to each set top box through the fixed frequency points. After obtaining the device identifier of the set-top box corresponding to the channel playing request, matching the obtained device identifier with a preset frequency point distribution list, searching whether the device identifier matched with the obtained device identifier exists in a device identifier area in the preset frequency point distribution list, if so, obtaining a broadcast channel corresponding to the device identifier, and taking the broadcast channel as a broadcast channel for issuing program data corresponding to the channel playing request.
Illustratively, if the device identifier included in the channel playing request is 2, a preset frequency point allocation list is searched, and a broadcast channel corresponding to the device identifier 2 in the frequency point allocation list is used as a broadcast channel for issuing program data corresponding to the channel playing request.
S130, program data corresponding to the channel playing request is obtained, and the program data are broadcasted through the broadcasting channel, so that the set top box corresponding to the equipment identifier receives the program data through the broadcasting channel.
In this embodiment, after obtaining the channel identifier included in the channel playing request, the program data corresponding to the channel identifier may be determined by searching the program list, and the determined program data is played through the broadcast channel.
Optionally, when the broadcast control server broadcasts the program data corresponding to the channel identifier, the broadcast channel is changed but the broadcast frequency point is not changed with respect to the set-top box corresponding to the channel broadcast request, so that the scrambling manner of the program data is not changed, and when the broadcast control server completes the program switching of the corresponding channel, the set-top box device also completes the program switching of the corresponding channel at the same time. Therefore, no matter what programs are switched, the frequency point switching, the control word resetting, the descrambler resetting and the audio and video decoder resetting are not needed any more relative to the set-top box equipment side. Therefore, the switching speed of the channel provided by the embodiment of the invention completely depends on the communication time and the time for controlling the playing server to switch the program. Optionally, a high-performance server may be selected as the control playing server, and the processing speed of the high-performance server is much faster than that of the set-top box device, so that the channel switching speed of the high-performance server is much faster than the conventional channel switching speed.

It should be noted that, in consideration of the limitation of the whole frequency point resource, the channel playing method provided by the embodiment of the present invention may be used in combination with a conventional channel playing method, that is, part of the set-top box devices may use the channel playing method provided by the embodiment of the present invention, and part of the set-top box devices may use a conventional broadcasting mode to broadcast programs. The channel playing method provided by the embodiment of the invention is also suitable for the on-demand system, and when the on-demand request initiated by the mobile terminal is received, the corresponding program data is issued to the set top box equipment corresponding to the equipment identifier contained in the on-demand request through the method.
