The embodiment of the invention two provides a kind of control method of playing programs.In this method, the digitized representation program number on the user remote controller, what the user selected is program number.The program of this program number correspondence is in which concrete cannel broadcast, then by can dynamically determining according to the situation of channel resource by CMTS, and with the result notification STB (such as comprising information such as channel identication in the result who determines) that determines, STB can see selected program in the channel received signal of appointment.This embodiment is provided with a program channel table on CMTS, what write down in this program channel table is mapping relations between program number and the channel identication.Need to prove that program number wherein is used for programme content of unique identification.The specific implementation step of this embodiment is as shown in Figure 2:
After the step 201:STB start, with being connected and authenticating of CMTS.Authentication obtains the IP address by back STB.
Step 202: the user selects the required program of watching, and STB sends play instruction according to the CMTS sign that the user belonged to the CMTS of correspondence; Comprise user selected program number in this play instruction.
In this embodiment, the program channel table among each CMTS is the program resource pool of a logic, can be made up of two parts: a part is current in progress program, and another part is the current program of not playing.For in progress program, can from the program channel table, inquire the channel identication of this program number mapping; For the current program that does not have broadcast, then there is not the channel identication of mapping.
Step 203:CMTS receives play instruction, obtains program number wherein, carries out playback process.Specifically comprise: judge whether it is in progress program, if then CMTS obtains the channel identication of program number correspondence according to program number and program channel table, the channel identication of correspondence is handed down to STB, STB is then at the channel section program receiving signal of appointment;
Otherwise what the user selected is the current program of not playing of CMTS, if CMTS has not had available channel resource, CMTS is the playing request of refusing user's directly; If CMTS also has idle channel resource, then can be by CMTS to this programme content of content server requests.CMTS is as follows to the concrete steps of this programme content of content server requests:
A) the content server channel of inquiring about this CMTS takies situation, when this CMTS has the idle channels resource, then content server pushes to this CMTS with the programme content of user selected program correspondence, or is added the program place multicast group of program number correspondence to the content server application by this CMTS;
B) CMTS selects one idle channels to be used to play the programme content of this program number correspondence, and the channel identication of this idle channels is related with program number, upgrades current program channel table simultaneously;
C) CMTS is handed down to STB with selected channel identication and program source, by STB program receiving content on the channel of appointment.
In the present embodiment, can also carry out following setting on CMTS: if the CMTS channel at user place takies at full capacity, the user can only select in the current channel list that is broadcasting so; If certain broadcast channel has above certain hour (such as 5 minutes) watch without any the user, CMTS can reclaim this channel, is about to this channel and is set to idle condition.
In the present embodiment, under CMTS channel quantity full load situation, in order to expand increased number of available channels results, can also be the program that can play in the local P2P network, be fused in the DVB channel, when not having idle channels again, can switch to the program that IP tunnel is watched selection in case the user has selected program.
The foregoing description dynamically provides the program channel table by the DVB broadcast channel for fixed amount, search corresponding programme content by this program channel table, by the corresponding relation between CMTS control program channel and the program, this corresponding relation can dynamically be adjusted according to demand, make on limited hfc plant bandwidth, increase the number of programs that the user can watch.
In the foregoing description two, can also store some programme contents at STB and CMTS, select to watch for the user.When the user watches program, program fragment is buffered in STB; Utilize the storage capacity of CMTS to constitute program shared network (such as the P2P network that can be localization) jointly like this between each STB and the STB; And, upgrade the program channel table of corresponding CMTS according to the program source situation of each STB buffer memory.In this case, the program channel table of CMTS is made of three parts: the one, and current in progress program, the 2nd, the program of current cache in the P2P network, the 3rd, the current program of not playing; Wherein the current cache program has utilized the bandwidth ability of local P2P network, does not influence the broadcasting channel quantity of CMTS.In order to realize the differentiation of above-mentioned three partial programmes, can use special mark or other modes to realize at the program channel table.
The required program channel of watching of user terminal selecting if selection is the program of current cache, is then directly play in the P2P network; If what select is the current program of not playing of current in progress program or CMTS, similar with embodiment two.
