Description
Technical field
The present invention relates to the communications field, particularly the recording technology of Media Stream.
Background technology
Growing along with computer network, based on network multimedia transmission is more and more universal, and people increase day by day to the requirement of multimedia communication content, people no longer are satisfied with single, passive traditional media entertainment way, and real needs is personalized, interactive broadband streaming media amusement, particularly along with the further developing of mobile communication network technology, mobile multimedia has more and more shown user's cognition and the acceptance that it is extensively following and reach its maturity.
Multimedia technology is multiple media collection all-in-one-piece technology such as literal, sound and images.The development of mobile communication makes multimedia technology also more and more closer with combining of mobile communication, along with 3G (Third Generation) Moblie (The Third Generation, abbreviation " 3G ") commercialization worldwide, and the 2.5th third-generation mobile communication (2.5G) in the preview of China, people recognize day by day, are the core application that the multimedia service of characteristic will become future mobile communications with audio frequency and video.The multimedia that combines with mobile communication is that mobile multimedia has been brought a kind of brand-new AC mode, and user terminal changes a kind of brand-new medium that content and service can be provided into whenever and wherever possible also from simple means of communication.
Mobile multi-media service can be divided into three classes such as Streaming Media (streaming media), Multimedia Message, video communication.Wherein, stream media technology is a kind of multimedia application technology that grows up from the Internet.So-called stream media technology is that data transmit with continual stream mode to client from server end, just begins to play when first packet arrives.Stream media technology does not need to download multimedia file, so the user does not need to wait as long for.Corresponding with it traditional approach is multimedia file to be downloaded to user terminal could play afterwards.Streaming Media be one will communicate by letter, Internet etc. is fused to new technology together, can audio plays and content of multimedia such as video by streaming media service, also can carry out program request to it, has interactivity, for example based on the professional employing mobile flow medium video traffic that stream media technology realized of mobile video.The flexibility of mobile flow medium service, and characteristic such as the Streaming Media time-delay of start playing is very short make the user can watch uppick mobile video and audio frequency immediately.Therefore Streaming Media will become the basic communication form on the next generation network (Next Generation Network is called for short " NGN ").
Streaming Media (streaming media) has derived numerous multimedia communication service forms as a kind of basic multimedia communication form: video conferencing/video telephone, Web TV, VOD (program request), instant messaging or the like.Especially in recent years, the rapid rising of domestic and international network TV business, the application of Streaming Media on network is also in development rapidly.
Countries in the world, especially North America and Europe, and developed country such as Japan and Korea S have all begun to actively promote carrying out of the relevant standardization activity of Web TV.International Telecommunications Union's (InternationalTelecommunication Union is called for short " ITU ") has set up the standard formulation work that so-called Web TV ad hoc working group (IPTVFocus Group) lead the whole world at present.Domestic in China, also have with CCSA (Chinese Communications Standardization Association, be called for short " CCSA ") and formulate domestic relevant industries standard for leader's ad hoc working group.And (the Alliance of TelecommunicationIndustrial solutions IPTV Interoperation Forum of the Web TV interoperability forum of the communication standard TIA of North America, be called for short " ATIS IIF "), the digital television broadcasting in Europe provincialism normal structures such as (Digital Video Broadcasting are called for short " DVB ") has also all been carried out relevant standard operation.
In the research and standardisation process of Web TV, some typical services in the Web TV are paid much attention to.Wherein a typical services is so-called " personal video recording " (Personal VideoRecording is called for short " PVR ").Exactly from the video/audio content of Web TV on the local memory device that the network television user terminal is connected (such as hard disk), perhaps store in network storage space (need to pay and use), for watching or serve other purposes later on.The network television user terminal can be STB (network machine top box), also can be PC (personal computer).
Its basic functional principle as shown in Figure 1, the professional user of permission of PVR is when watching network TV program to broadcast, select certain segment in the program recording by users such as remote controller input and control appliance as required, under the control of user instruction, the network television user terminal video/audio stream of automatic network TV network in the future is written to local memory device, preserves, and the form of preserving is a multimedia file usually, such as AVI, mpg etc.
Certainly can also use online memory space by paying, this memory space is generally also provided by Web TV operator.If use the online storage space, video/audio stream can directly be sent memory device to the Web from content source (being streaming media server) and preserves so.Certainly the user also can such as timed recording, perhaps record some specified channel etc. by setting some condition, realizes automatic personal video recording.
Because no matter the network storage is from the technology or angle of telecommunications/Internet value-added service, developing all is very rapidly.The network storage has enlarged individual memory space, make the network television user terminal to download more contents and needn't worry to need the constantly own hard disk of upgrading, this consumer behavior can cause operator to obtain the service income of more bringing by content download and flow increase.
But, present network TV business still reckons without many potential application scenarioss, as efficiently and personalized record, automated intelligent is recorded and according to user's use habit and other parameter selectively, network study and the service of making to measure etc. is provided automatically automatically.
Specifically, the program that Web TV broadcasts in order to guarantee viewing quality and user experience, often adopts higher bit rate to encode and send; The compressed encoding form may also be limited several in addition, such as MPEG-2/MPEG-4/H.264 etc.For the user, just there are two problems:
A. can't save the storage spending: high bit rate means the program of recording same length, needs memory space bigger, thereby spending is bigger.
B. can't realize that personalization records: the purpose that the user records is used on certain media player often, such as MP3, and the MP4 player, the limited storage space on it, and the codec format of supporting also is limited.According to the present mode of recording, can't be according to the ability recorded video program of subscriber equipment.
In addition, some user not necessarily will record the whole of a slice, thin piece, just need record some excellent camera lenses wherein, such as the goal scene in the ball, and the last item in the action movie etc., perhaps scene relevant in the news etc. with certain very important person/star.And, can't realize this difference hobby according to the user according to the present mode of recording, the final playing environment of program recording, and the attribute of program (physical culture, action movie are taught, news) carry out the intellectuality of content choice and record to video frequency program.

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In embodiments of the present invention, by the PVR control subsystem to the network side entity sending controling instruction that is used for recording medium stream, this network side entity judges according to the control command of receiving whether Media Stream and user configured recording attributes to be recorded mates, if, then directly this Media Stream is recorded to network storage space, otherwise, be recorded to network storage space after by recording attributes this Media Stream being changed.Wherein, for video media stream to be recorded, it is one of following that the mode of Media Stream being changed by recording attributes comprises at least: conversion between media formats, media formats internal conversion, selection are also extracted the intelligent conversion of part Media Stream; For audio medium stream to be recorded, the mode of Media Stream being changed by recording attributes comprises: conversion and/or media formats internal conversion between media formats.
Below first execution mode of the present invention is elaborated, present embodiment relates to the method for recording of Media Stream, and the Media Stream in the present embodiment is the Web TV Media Stream, and idiographic flow as shown in Figure 2.
In step 210, the PVR control subsystem is to the network side entity that is used for recording medium stream, PVR support function entity just, and sending controling instruction is notified the recording attributes of this entity user configuration.Wherein, the PVR control subsystem is supported following function:
A. fully control and manage for the PVR business.
B. receive request, and handle from the network television user terminal.The request of user terminal comprises following aspect:
B1. user terminal requests is recorded according to input parameter for current play content;
B2. user terminal requests begins to record and end is recorded;
Select one one configuration set item to record in the service configuration of B3 user terminal from database Already in as recording attributes;
C. the user imports new recording attributes, joins in this user's the service configuration to go.
D. from user's input, study analysis user's use habit is liked etc. automatically, replenishes the service configuration of improving this user.
E. from customer data base, extract user's service configuration data, become control command and control PVR support function entity.
Because the PVR control subsystem need notify PVR support function entity this user configured recording attributes by control command, so the PVR control subsystem at first needs to obtain earlier this user configured recording attributes.
Specifically, the PVR control subsystem is obtained one of in the following manner earlier the current user configured recording attributes that is used for recording medium stream:
According to the request that this user's user terminal sends, from the PVR service configuration of customer data base, obtain the recording attributes of this user's appointment, as this user configured recording attributes;
From the request that this user's user terminal sends, obtain the recording attributes of the up-to-date appointment of this user, as this user configured recording attributes;
From the PVR service configuration of customer data base, obtain the attribute that similar program was recorded in the past, as this user configured recording attributes;
Adopting default recording attributes is user configured recording attributes.
Briefly, the user can have three kinds of possibilities when recording for certain specific program:
A. the user specifies which data item that adopts in its service configuration as recording attributes to the PVR control subsystem, and at this moment, the PVR control subsystem is taken out corresponding data from customer data base, records by control command control PVR support function entity.
B. the user specifies new recording attributes to the PVR control system, and in this case, PVR records according to the new recording attributes of user's appointment by control command control PVR support function entity.
C. the user does not specify any recording attributes, at this moment, the PVR control subsystem at first go to find in the customer data base one with need program recording attribute matched data item (attribute of recording in the past as similar program) the most, as recording attributes; If new user, its user's service configuration is empty, and then the PVR control subsystem adopts one group of default recording attributes, and the PVR control subsystem is recorded according to this recording attributes by control command control PVR support function entity.
In the PVR of customer data base service configuration, one of can be in the following manner or its combination in any preserve recording attributes:
A. preserve recording attributes according to program category: different program category corresponding recording attributes, this part data is organized according to different program categories, has one group to record parameter such as news program, and film has other one group to record parameter, as:
Program category is recorded parameter for 1 one groups
Program category is recorded parameter for 2 one groups
Program category N records parameter for one group
B. preserve recording attributes according to specific program: different specific program corresponding recording attributes, this part data is organized according to different specific programs.Here will specify recording attributes according to particular program name, record parameter for corresponding one group such as " news hookup " this specific program, " Animal World " corresponding one group of other parameter of recording, as:
Specific program is recorded parameter for 1 one groups
Specific program is recorded parameter for 1 one groups
Specific program M records parameter for one group
C. select to preserve recording attributes according to condition: this part data is organized different parameters according to the various combination condition, combination condition can define arbitrarily, adopt logic connective such as AND, OR, NOT wait and make up (such as, combination condition 1=action movie AND foreign films AND length of a film was less than 150 minutes), as:
Combination condition is recorded parameter for 1 one groups
Combination condition is recorded parameter for 2 one groups
Combination condition P records parameter for one group
Then, enter step 220, PVR support function entity judges whether Media Stream and user configured recording attributes to be recorded mates.
Specifically, after PVR support function entity obtains user configured recording attributes according to the control command from the PVR control subsystem, judge whether the attribute of broadcasting Media Stream from the network TV content source to be recorded is complementary with user configured recording attributes, if coupling, then enter step 230, directly this Media Stream is recorded to network storage space, just this Media Stream is recorded to network storage space; If do not match, then enter step 240, PVR support function entity is changed this Media Stream by user configured recording attributes.The trend of Media Stream each inter-entity in system as shown in Figure 3.
Specifically, in step 240, the mode that PVR support function entity is changed the Media Stream of video by user configured recording attributes comprises one of following or its combination in any: conversion between media formats, media formats internal conversion, selection are also extracted the intelligent conversion of part Media Stream; The mode that the Media Stream of audio frequency is changed comprises conversion and/or media formats internal conversion between media formats.That is to say that PVR support function entity duplicates this Media Stream earlier, obtains a replication stream, again this replication stream is transformed into user configured recording attributes is complementary and records stream.Following elder generation is elaborated to the conversion of video flowing and audio stream.
PVR support function entity is used to carry out change between media formats and the basic functions of media formats internal conversion comprises:
A. for video flowing, comprise the conversion of following attribute:
