Definitions
- zapping time or time of change of channel
- chain we mean conventionally what users call a television channel, for example a channel broadcasting during the day successive programs to each other.
- the field of the invention is, in general, that of digital television decoders that broadcast ultra-high definition UHD (Ultra High Definition) or / and High Definition HD or / and SD of English Standard-Definition.
- UHD Ultra High Definition
- HD High Definition
- SD Standard-Definition
- D digital television decoders are used, in particular to access a set of television channels that are transmitted encrypted and decrypted within the decoder.
- D television decoders are interface organs, associated in the case of channels via the Internet to modem-type devices, between television signal transmission systems, in particular digital television signals in UHDTV format, and monitors.
- display comprising a display member E.
- the monitor may include the decoding member D and the display member E comprising a screen.
- the decoding device D can also be connected to the monitor.
- the signals exchanged are most often digital signals, but a decoder D can also have faculties of analog signal processing.
- the transmission means that transmit the television broadcasts to these decoders / receivers are either transmission means by "Broadcasting” ie via satellite or TNT, or by the Internet network also called “Broadbanding” is at say via internet box or live via website.
- decoders D receiving a signal flow via the Internet network, therefore by transmission by "Broadbanding", but the implementation of the method according to the invention is not limited to this type of decoders D but to any channel decoder D via the Internet.
- the formatting is carried out respecting for each of the images to represent tables of parameters.
- tables There are different types of tables: the SI (System Information) tables, the PSI (Program Specific Information) tables, the NIT (Network Information Tables) tables, the EIT tables (Event Information Tables), the PAT tables (Table of Associated Programs), the CAT (Access Control Table) table or the PMT (Program Component Table) tables ...
- SI System Information
- PSI Program Specific Information
- NIT Network Information Tables
- EIT tables Event Information Tables
- PAT tables Tablet of Associated Programs
- CAT Access Control Table
- PMT Program Component Table
- the data packets of a channel are transmitted to the decoder by download also called downloaded string.
- the broadcast channel is thus downloaded to the decoder to allow the decoder to decode and transmit signals applicable directly to the control elements of the display device E to display on a screen the chain M.
- a whole table architecture is distributed and the purpose of the decoder is to rebuild all the tables to have adjustment information as well as information to show in visualization for users.
- Figure 1 shows a packet transmission diagram between an IPTV provider and a user.
- the IPTV provider F transmits data packets 1 of an N chain, these packets 1 pass in routers R on a public network and then arrive at the user by an Internet Box B also called modem, which retransmits to the decoder D the packets 1.
- the packets 1 are then decoded so that the display E which may be a television, a video projector, etc. displays the string N.
- the bit rate of uncompressed video in UHD is for example 2388 Mb / s to 71663 Mkb / s depending on whether it is LIHD-1 (4K) or UHD-2 (8k). It is therefore known to compress the image to reduce the bit rate.
- bit rate required can vary between 1 Mbps and 3 Mbps
- the bit rate can vary from 4Mbps to 15Mbps
- the bit rate can vary from 10Mbits / s to 30Mbits / s (see above).
- a zapping action 100 causing a chain change signal 101 to the decoder D will cause a succession of steps described below in connection with Figure 1.
- Such action is for example a support on one or more keys appropriate a remote control associated with the decoder, for example pressing a "P +" or "CH +" key on the remote control.
- a first step then resides in the consideration by the operating software of the decoder D, the action of the user.
- IGMP join command in this case the string M
- IGMP leave command in this case the string N.
- the duration of this step corresponds to a connection time of the decoder , time required, from the execution of the IGMP join command, to receive first appropriate data packets extracted from one or more signal streams.
- the provider then goes on to a third step sending the data packets 2 concerning the channel M to the user U, that is to say to the internet box B which will transmit these data to the decoder D.
- the decoder comprises all the data necessary for the display of the channel
- a decoding and buffering step follows, in which the decoder D decodes and buffers data 2 to synchronize itself with a signal. image display of the stream and accumulate data 2 to be resistant to fluctuations in the network and finally a step of sending applicable signals directly to the control members of the display device E to display on a screen the chain M.
- LCC chain change latency is defined between the instant of the first packets 2 of the M string received in the decoder D and the sending of applicable signals on the control members of the display device E.
- the TZ zapping time is therefore the LCC chain change latency and the LT download latency.
- a zapping action 100 of a chain N to a chain M is performed by the user.
- the TZ zapping time corresponds to the sum of the LT download latency which is depending on the case approximately 1 to 2 seconds in the case of a UHDTV string and the LCC string change latency which is less than 0.5. seconds.
- This TZ zapping time can be problematic for the user, especially if it exceeds the 2 seconds recommended by the DSL Forum in terms of the quality of the required QoE user experience (Quality of Experience).
- At least one other string is downloaded (hence 2-d packets).
- at least one string is transmitted to the decoder), in this case two other chains: the chain N + 1 corresponding in our example to the chain M and the chain N-1, called in the following chain O.
- the zapping time corresponds only to the LCC change of channel latency since the M channel is already downloaded. It follows that the decoder D sends the applicable signals to the control members of the display device and the user waits less than 0.5 seconds to see the chain M on the display member E.
- the chain N continues in this example to be downloaded and a chain L corresponding to the chain M + 1 or N + 2 is downloaded at the same time as the chain M.
- the total bit rate can therefore vary between 30Mbits / s and 90Mbits / s (see below). of the).
- the ZT zapping time is an important parameter in the assessment of the quality of the services provided by an operator. This quality is evaluated regularly by an important body. It is therefore necessary to take care of this characteristic of the decoders, a characteristic which is directly appreciable by the end user.
- the method according to the invention proposes a solution to the problems and disadvantages which have just been exposed.
- a solution allowing an optimization between the reduction of the bandwidth used by the decoder to allow another use of the bandwidth between the portal of their operator and their reception means when a channel is watched from a certain time and the reduction of zapping time when the user shows precursors of a possible zapping action.
- the invention therefore essentially relates to a method of downloading channels for zapping a digital channel to another digital channel in a decoding device configured to decode a channel and transmit it to a screen
- the decoding device comprising a module downloading method comprising a state of activity, wherein the method comprises, in the activity state, a step of downloading a first display chain in an activity quality and at least one other chain in parallel the first channel, the download being performed according to a bit rate of activity, the download module further comprising a state of inactivity having a download inactivity bit rate lower than the activity bit rate in which the method comprises the steps of: downloading the first channel in the activity quality; receiving a signal of a chain change warning signal, changing the state of the download module from the idle state to the activity state when the signal of a warning sign chain change was received.
- the download module downloads strings, for example in the example of FIG. 2b.
- the bit rate is lower than the idle state than in the state of activity allows that in case of saturation of the bandwidth in the state of activity, the bandwidth may not be saturated. in idle state.
- the idle state of other products can download at a higher bit rate than in the state of activity. This avoids a degradation of another use with another product on the internet. Switching from idle state to activity state before potentially a chain change request decreases the zapping time.
- the invention optimizes the use of the downloading of a chain to the state of inactivity to reduce the band passing while reducing the average zapping time by returning to the state of activity before a request for change of channel .
- the zapping time is not reduced if the string requested by the user is not the at least one string downloaded in parallel.
- the decoder is not in sleep but is in a state of use using less bit rate than in the state of activity.
- the step of downloading at least one other chain in parallel than that transmitted in the activity quality is performed during decoding and transmission steps of the first channel that is decoded. These decoding and transmission steps are described later.
- the determining step may comprise various operations consisting of:
- the reference threshold value can be stored in a memory of the decoder, for example in the download module.
- the determining step may further comprise an operation of: receiving an activity signal, resetting the dwell time measurement at each activity signal reception.
- the measuring action of a rest period is a countdown having a reference threshold value for example of 15 minutes.
- the warning sign signal may comprise a signal sent by a remote control member to the decoder, in particular a signal from a displacement sensor of the remote control member.
- the displacement sensor may for example be an accelerometer or a gyroscope.
- the method may comprise a step of detecting a warning sign signal when a received acceleration signal is greater than or equal to a threshold signal representative of an acceleration of 0.3 g, preferably greater than 0.5 g. 1 g equals 9.81 meters per second or 0.3g is equal to 0.3 * 9.81 m / s or 2.94 m / s.
- the method may comprise a step of comparing an acceleration signal received with at least one threshold signal representative of an acceleration of 0.5 g and that if the acceleration signal is greater, a sign signal fore-runner of a sign change is considered detected.
- the warning sign signal comprises a signal from a measurement of the remote control sensor indicating at least an acceleration of 0.5g or at least i g-
- the decoder may determine that a signal from the remote control member indicating at least one 1 g acceleration is a warning signal of a sign change.
- an activity signal is a signal from a remote control sensor measurement indicating at least 0.5g acceleration and a warning sign signal to transition from idle state to Activity state includes a signal from a remote control sensor measurement indicating at least 1 g of acceleration.
- the decoder can disassociate a signal from the remote control from the accelerometer representing an acceleration lower than for example 0.3g can be a displacement of the support of the remote control.
- the warning sign signal sent by the remote control member may comprise a signal of a pressing on a request button of the remote control member.
- this is not a change of channel because it would not be a harbinger of chain change.
- the remote control member comprises channel change keys on the one hand and request keys on the other, such as increasing or lowering the sound volume, information, direct recording, etc.
- the off key or "off" to put the decoder on standby can not of course be interpreted as a warning sign of change of channel.
- the warning sign signal may also include a signal received from a microphone corresponding to a keyword.
- keyword is meant one or more words of a key phrase.
- the keyword can be the beginning of a sentence to open an application in the decoding device.
- the signal may be a key word or phrase to trigger the decoder.
- the warning sign signal comes from an action on the decoder or a decoder accessory that can come only from the user.
- a remote control movement comprising a motion sensor or an enumerated keyword picked up by a microphone of the decoder or a request button pressed on the remote control or the decoder member.
- the query key can not be a program change key.
- the warning sign signal may also be the opening of an application of a remote control member.
- a remote control member for controlling the decoder which sends an application opening signal to the decoder and which is taken into account as a warning sign signal .
- Switching from a sleep state to an activity state of the application can also be a warning sign signal.
- the decoder D1 is further configured to perform a method of broadcasting the downloaded N channel.
- the broadcasting method comprises a step of decoding the downloaded N string.
- the N chain is decoded by a decoding block D16.
- the broadcasting method further comprises a step of transforming the decoded channel into signals directly transmittable to control members of the television E1.
- the decoded channel is transformed by a display interface D17 of the decoder D1.
- the television E1 can therefore display on a screen the chain N.
- the decoder D1 is therefore configured to transmit these signals through its output D10 to the display member E.
- the download module is set to idle state to continue downloading the first displayed M channel.
- the quality can be the same or can be improved.
- the id id download of a single N string can be performed in a unicast stream.
- the downloading of the chains N, N + 1 and N-1 can be carried out in by downloading several streams in parallel.
- the loading method further comprises steps in the idle state of: ⁇ receiving a signal of a chain change warning sign 103 by the user
- the method may comprise a step of detecting a warning sign signal 103 when a received acceleration signal is greater than or equal to a threshold signal representative of an acceleration of 0.3 g, preferably greater than 0.5 g. or 1 g.
- the remote control is configured to perform the comparison step, the method further comprises a step of sending a warning sign signal to the decoder only if the measured acceleration signal by the sensor is greater than a threshold value for example 0.5g or at least 1 g. This makes it possible to determine a decision of the remote control by the user.
- the warning sign signal can also be an advertisement detection in the chain.
- the detection can be carried out by increasing the volume in the decoding of the packets.
- FIG. 5b shows the case of a warning sign signal of a chain change 103 without the user having changed channels.
- the download module switches to the activity state from this warning sign signal of a received channel change 103 and after a download latency, the N + 1 and N-1 strings are downloaded.
- the countdown thus measures a rest period and if the user does not perform any action, especially on the remote control, no activity signal is sent.
- the idle time in this case fifteen minutes, the download module goes back to the idle state.
- FIG. 5c represents such a case, for example, the user catches his remote control TC and therefore the displacement sensor identifies a change of orientation of the remote control by the user representative of a warning sign signal of a change of channel 103 and then presses a button "P +" or also called “CH +" of the TC command to zap to the next chain M (N + 1).
- FIG. 5c shows that after detecting the warning sign signal of a channel change 103, a zapping action 100 during the activity state E1 causes a channel change signal 101.
- the M channel being downloaded, the TZ zapping time corresponds to the LCC channel change latency.
- a zapping process is then described explaining how the channel change is performed
- the parallel downloaded channels become the M + 1 chain corresponding to N + 2 chain and the N (M-1) chain continues to be downloaded.
- the download module is configured so that the method further comprises in the downloading step of the chain M the download of a single other chain in parallel, for example N + 1.
- the number of chain downloads in the activity state is greater, in this case three, than the number of idle state strings, in this case two strings.
- the bit rate is therefore lower than the state of inactivity than in the state of activity.
- the decoder D1 comprises a channel zapping method comprising the downloading method according to one of the embodiments described as well as the broadcasting method described above and a step of receiving the signal for changing a requested channel 101 and then a step changing the decoded channel N to the requested channel M according to the channel change signal 101.
- the channel change is made by interrupting the decoding and transmission of the decoded channel N and then performing the steps of decoding and transmission of the requested string M.
- the decoder D therefore executes a so-called "IGMP join command” in this case the M chain and a so-called “IGMP leave command” in this case the N-channel to the internet provider.
- the chain change is possible in the two states of the decoder D1 (activity or inactivity).
- state of activity EA the chain change will be done with a zapping time TZ corresponding to the LCC string change latency if the requested string M by the user corresponds to the or one of the channels downloaded in parallel with the decoded channel N before the reception of the channel change signal 101.
- the channels downloaded in parallel to the decoded channel are the following string N + 1 and the preceding string N-1.
- the channels downloaded in parallel are other channels than the next and previous channels of the channel displayed.
