Definitions
- the invention relates to a method and to an apparatus for timestamping a bitstream to be recorded or for using time- stamps when replaying from a stream recorder, e.g. an optical disc recorder.
- Stream recording assumes an 'application device', e.g. a settop box, connected to a DVD Streamer. Both devices are connected via e.g. an IEEE1394 (IEC 611883) interface which in its transmitting and receiving firmware contains means to timestamp data and to strip off these timestamps again, using them for timing regeneration.
- IEEE1394 IEEE 1394
- EP-A-0 701 374 describes the recording of superpackets each including a timestamp.
- a stream recorder must re-generate the timing of data packets as it was upon recording, when these packets are played back, so that between recording and playback this system also behaves like a constant delay system.
- the stream recorder adds its own timestamps to the data packets when recording and evaluates them when replaying in order to assign to the data packets the correct temporal position. Thereby the original data packet burst characteristic is reconstructed for a data stream having in principle non-equidistant data packets.
- there is an in-series connection between two time- stamping and time regeneration mechanisms which can introduce jitter accumulation.
- the application device itself before sending the data through the IEEE1394 interface, adds time stamps to the data packets.
- These timestamps may have the meaning of 'departure time' rather than 'arrival time' and pass the IEEE1394 interface 'unnoticed', i.e. from a IEEE1394 interface point of view they are part of the payload.
- these timestamps are used when the stream recorder plays back a stream.
- the advantage is that there is only one timing/regeneration process involved which has influence on the temporal position of the replayed data packets, and that therefore no jitter is accumulated.
- the stream recorder does not make use of the IEEE1394 timestamps.
- the stream recorder records the IEEE1394 timestamps and evaluates them when replaying in or- der to assign to the data packets the correct temporal position.
- the inventive method is suited for: timestamping a bitstream to be recorded or for using time- stamps when replaying from a stream recorder, wherein a device or signal source outputting said bitstream to be re- corded adds said timestamps to data packets of said bit- stream and wherein the data packets of said bitstream pass to said stream recorder through a network which causes network jitter and for which network said timestamps belong to the payload of said data packets, and wherein said time- stamps are used when replaying said data packets from said stream recorder in order to relocate the replayed data packets to the corresponding original temporal position in said bitstream,
- timestamping an MPEG bitstream to be recorded or for using timestamps when replaying from a stream recorder wherein MPEG timestamps are included in data packets of said MPEG bitstream to be recorded and for the recording additional timestamps generated by said stream recorder become attached to the data packets of said MPEG bitstream to be recorded, and wherein said additional timestamps are used when replaying said data packets from said stream recorder in order to relocate the replayed data packets to the corresponding original temporal position in said MPEG bitstream,
- the inventive apparatus is suited for time- stamping a bitstream to be recorded and includes:
- - program selection means which provide data packets from said bitstream, the data packets belonging to a specific program; - a network interface which provides data of said data packets to a stream recorder or which receives data of said data packets from said stream recorder, wherein the related network causes network jitter and for which network said time- stamps belong to the payload of said data packets and wherein said timestamps are used to relocate the replayed data packets to the corresponding original temporal position in said bitstream;
- a Stream recorder for a bitstream, including: - a network interface which provides data of data packets of said bitstream including timestamps, having been inserted outside said network interface, for recording or which receives replayed recorded data, wherein the related network causes network jitter and for which network said timestamps belong to the payload of said data packets;
- - stream recording means which record data of said data packets including said timestamps or which replay data of said data packets, wherein during replay said timestamps are used in order to relocate the replayed data packets to the corresponding original temporal position in said bitstream before the replayed data packets enter said network interface
- a Stream recorder for a bitstream, including: - a network interface which provides data of data packets of said bitstream, said data packets including MPEG timestamps, for recording or which receives replayed recorded data for data packets including said MPEG timestamps; - stream recording means which record data of said data packets, including said MPEG timestamps, and additional timestamps generated by said stream recording means which become attached to the data packets of said MPEG bitstream to be recorded, or which replay data of said data packets, wherein during said replay said additional timestamps are used in order to relocate the replayed data packets to the corresponding original temporal position in said MPEG bit- stream,
- - a network interface which provides data of data packets of said bitstream for recording or which receives replayed recorded data, wherein the related network causes network jit- ter and which network internally adds network timestamps to data packets of said bitstream in order to reduce said jitter when outputting said data packets;
- - stream recording means which record data of said data packets including said network timestamps, or which replay data of said data packets, wherein during replay said network recorded timestamps are used in order to relocate the replayed data packets to the corresponding original temporal position in said bitstream before the replayed data packets enter said network interface.

- Fig. 1 transport streams are received by an antenna ANT and pass through a tuner TU selecting one of the transport streams, and through a demultiplexer DEM.
- time stamps can be inserted in a time stamp inserter TSI which receives the time stamps from a time stamp generator TS.
- An application device which can be a DVD stream recorder including stream recording means STRREC, receives output data from DEM or TSI, respectively, via an IEEE1394 interface transmitter 1394TR and an IEEE1394 interface receiver 1394RECS.
- the data replayed from STRREC pass through an IEEE1394 interface transmitter 1394TRS and an IEEE1394 interface receiver 1394REC to decoder means DEC which deliver the final output signal or signals 0.
- DEC may include a video decoder, one or more audio decoders and one or more additional data decoders.
- any other network causing network jitter like the Ethernet or the Internet can be used.
- TU, DEM, TS, TSI, 1394TR, 1394REC and DEC can be parts of a settop box.
- 1394RECS, STRREC and 1394TRS can be parts of a DVD stream recorder.
- any other data stream source can be used, e.g. a DVD player or a PC or Internet receiver.
- ANT and TU is replaced by e.g. an optical disc and a pickup.
- Fig. 2 depicts the temporal behaviour of certain items of the received PES stream with respect to the functional blocks in Fig. 1.
- Fig. 2a shows a transport stream with multiplex of packets of programs A, B, C and D, and SI information at the output of TU in Fig. 1.
- Fig. 2b depicts source packets of the selected program A with its relevant SI information at the output of DEM in Fig. 1.
- the black parts of the packets are the packet head- ers which include transmitted time stamps represented by the arrows .
- Fig. 2c shows source packets at the output of the smoothing buffer inside IEEE1394 transmitter 1394TR which causes such a delay that the packets are now essentially equidistant.
- Fig. 2d shows the source packets at the input of the
- FIG. 2e depicts the reconstructed timing for the source packets at the output of 1394REC which again introduces an additional delay.
- time differences ⁇ t]_ and ⁇ t2 of Fig. 2e finally correspond to that of Fig. 2b.
- the arrival time is the departure time plus the overall delay ODEL which is represented by a timestamp offset.
- the clock frequency for transferring the bytes of a transport stream may be different in different applications.
- An IEEE1394 system uses segments having a length of 125 ⁇ s, called cycle master packet. Within such cycle a data packet has a non-defined temporal position, i.e. a jitter range of maximum nearly 125 ⁇ s is introduced. Therefore the IEEE1394 system makes use of its own 'timestamps' which serve to temporally correctly relocate the packets within the 125 ⁇ s seg- ments at the output of an IEEE1394 receiver.
- An IEEE1394 transmitter includes a buffer at its input and an IEEE1394 receiver includes a buffer at its output, which smooth the average data rate. Additionally, in the IEEE1394 system a temporal compression of the data packets takes place which is apparent from the comparison of Fig. 2c and 2d. This compression also increases the maximum jitter at the demultiplexer output. In addition to the limited temporal resolution in the IEEE1394 system described above a fur- ther portion of jitter is added by the non-perfect 25MHz clock.
- a proposed stream recorder specification offers the possibility to record stream-recorder generated timestamps which are derived from e.g. a 27MHz clock.
- the stream recorder records the IEEE1394 time- stamps instead and evaluates them when replaying in order to assign to the data packets the correct temporal position.
- the length of the data packets is programmable in the
- the original 188 byte length of the transport stream packets is increased by e.g. 4 bytes to a total length of 192 bytes in order to add timestamps supplied from the ap- plication device, e.g. a settop box.
- the DVD Stream Recording system is designed to use rewritable DVD discs for recording existing digital bitstreams, editing them and playing them back as bitstreams.
- This sys- tern is designed to satisfy the following requirements:
- a timing mechanism i.e. a time stamp is added to every broadcast packet to enable proper packet delivery during playback.
- the system is designed to enable real-time recording of digital streams. It allows the user to concatenate recordings, even if those recordings consist of different stream formats. If recordings are concatenated, a seamless or close-to-seamless playback feature can be achieved, but is not required.
- An 'original' version of a play list contains quite low level information, e.g. time map or (broadcast) packet order of the recording. This list is accessible by the STB and the content is understood by the DVD streamer as well as by the STB. In its original version the playlist enables the playback of a complete recording. The playlist may be accessed and extended after recording by the STB to allow more sophisticated playback sequences.
- the second piece of information, a mapping list is generated to support the stream recorder to retrieve packet stream chunks (cells) , that are described in terms of the application domain, e.g. 'broadcast packets' or 'time'. This list is owned and understood by the DVD streamer only.
- the system can reserve space which can be used by the STB to store high-level TOC and Service Information. This information is provided for the user to navigate through the content stored on disc and may contain sophisticated EPG information. The content needs not to be understood by the stream recorder. However a common subset of the TOC information, e.g. based on a character string, may be useful to be shared between STB and DVD, in order to enable the stream recorder to provide a basic menu by itself.
- Playback of individual recording and playing all recordings sequentially is possible via a play list.
- Player menus for entry point sel ection are possible.
- the STB can generate a sophisticated menu based on the TOC information stored on the disc.
- a simple menu is generated by the streamer itself, e.g. via some 'character' informa- tion which is shared by STB and DVD.
- the STB can steer trick play via the 'play list'. Due to the nature of the broadcast stream, the trick play features may be limited to basic ones, e.g. Time Search and Title Jump. User defined playback sequence features like programming or parental control can be supported via the play list.
- the DVD streamer creates the 'original version' of the play list. It can allow extensions and modifications of the play list by the STB for more sophisticated playback features.
- the DVD streamer is not responsible for the content of those sophisticated playlist (s).
- the system supports the deletion of single recordings on user's request. Preferably the system allows this feature under the control of the STB.
- the system may support insert editing. Concerning the directory and file structure, the organisation of Stream Data and Navigation Data of DVD Stream Recording is done in a specific way such as to take into account the following: - Any DVD Streamer device has certain requirements to store its own housekeeping data or Streamer-specific navigation data on the disc. These data are solely for helping the retrieval of recorded data; they need not be understood or even be visible to any outside application device AD.
- Any DVD Streamer device needs to communicate with the application device AD it is connected to. This communication is as universal as possible so that the maximum possible range of applications can be connected to the Streamer.
- the Navigation Data to support such communication are called Common navigation data and must be understandable by the Streamer as well as by the application device.
- the Streamer device offers to the connected application device AD a means for storing its own private data of any desired kind.
- the Streamer needs not to understand any of the content, internal structure, or meaning of this application-specific navigation data.
- STRREC directory shall not contain any other files or directories.
- Stream Data include one or more 'Stream Objects' (SOBs) which each can be stored as a 'Program stream' as described in ISO/IEC 13818-1, Systems.
- SOBs 'Stream Objects'
- a SOB can be terminated by a program_end_code .
- the value of the SCR field in the first pack of each SOB may be non-zero.
- a SOB contains the Stream Data packed into a sequence of 'Stream Packs' (S_PCKs) .
- Stream data can be organised as one elementary stream and are carried in PES packets with a stream_id.
- the application performs its own padding so that the pack length adjustment methods of DVD-ROM Video or RTRW need not to be used. In Stream recording it is safe to assume, that the Stream packets will always have the necessary length.
- a Stream Pack has 2048 bytes and includes a pack header followed by a Stream PES Packet.
- a sys- tem header may be included in those S_PCKs which are the first S_PCK of a SOB.
- S_PCKs which are the first S_PCK of a SOB.
- the length of the remaining Stream PES Packet content may be 2010 bytes, and when not included, 2034 bytes.
- a pack is recorded in one LB.
- the pack header may include the following items of data:
- the stream PES packet header content is identical to that defined in the DVD standard, with the following limitations and additional rules:
- the 'stream_id' field is set to OxBD (private_stream_l )
- Each stream PES packet header carries a PTS timestamp. DTS timestamps are not encoded. Therefore the 'PTS_DTS_flags ' is set to '10b' .
- the ' PES_packet_length' includes any reserved bytes behind the last Application transport packet up to the end of the streamer DVD pack. Therefore the ' PES_packet_length' is always 2028 bytes.
- the Stream PES packet header may include the following items of data:
- Fig. 3 also shows that the Stream Data Area inside a Stream PES Packet includes an application header, an application header extension and a sequence of application packets, each prefixed by an application packet timestamp.
- the Application Header may include the following items of data:
- VERSION describes the version number of the application header format.
- APPLICATION_ID describes the application that generated the stream. If the application is unknown, 0x0000 is encoded.
- MAX_BITRATE describes the output bitrate parameter of the leaky bucket flow control model in Mbps.
- SM00TH_BUF_SIZ describes the buffer size parameter of the leaky bucket flow control model.
- TS_REF_CL_FREQ describes the reference clock frequency of the packet arrival/delivery timestamp.
- AP_PKT_LEN describes the length of the application packet, excluding the timestamp, in bytes.
- TS_LEN describes the length of the timestamp field in bytes and is set to the value '4'.
- AP_PKT_Ns is the number of application packets in this Stream PES Packet DVD pack:
- AP_PKT_Ns 1, 2, ..., 487 div AP_PKT_LEN
- the application header extension includes a list of entries, where there is exactly one entry of 1 byte for each Applica- tiontransport layer Packet. These bytes are used to store information that may differ from application packet to application packet.
- the total length of the application header extension is 46 bytes.
- the first 'AP_PKT_Ns' entries of these carry valid data. Unused list entries may carry undefined values.
- the total length of 'application header' and 'application header extension' is 71 bytes.
- ATS_base/90kHz + ATS_exten/27MHz cover a range of more than 93 seconds.
- the application timestamp describing format is depicted in Fig. 4.
