Definitions
- the invention relates to a transcription system and method.
- the invention has particular utility in the generation of captions for broadcasts and will be described hereunder in this context.
- Captions represent in text form the dialogue of a TV program, TV commercial, video, DVD or other cinema screening, including other features of the soundtrack such as sound effects and music.
- Foreign language subtitles are a translation of the dialogue only.
- Captions have certain style characteristics, such as colouring and positioning, (or placement on screen), to assist viewers to follow who is speaking. Captions are commonly displayed at the bottom of a TV or cinema screen but can be placed elsewhere within the screen, such as the top, to avoid covering important onscreen information or people's mouths.
- Offline captions are used for programs that are produced well in advance of airti e and that are unlikely to change once they've been produced, such as a drama series, or telemovie. These offline captions are embedded into the soundtrack of the program.
- broadcasts are transmitted from a central broadcasting point to a national network. From time to time, it may be necessary or desired to break into that national network broadcast (or feed) in order to insert local programming. This may include, for example, television stations in different States or Territories producing and broadcasting their own local news bulletins. While each State or Territory station produces a number of local stories of particular interest to their demographic, they may wish to file-share these stories with each other in order to gain sufficient content to fill their respective bulletins.
- captioning facility In addition to the point of broadcast requirement, traditional captioning methods and software have also meant that it is necessary for a captioning facility to be located onsite at the station in order to integrate or link captioning software with newsroom computer systems, which contain vital programming information, and to gain access to the local edit booths where the local stories are produced. Therefore, in order to caption each station's news bulletin or other locally produced program content, captioning personnel and equipment must be located onsite in each respective State or Territory.
- a common method is to employ a device that requires two telephone lines - one to receive audio, the other to send data.
- the quality of the audio is analogue, and neither the audio nor the data are handled in real-time leaving it subject to lengthy delays in transference.
- codec coder/decoder
- POTS Pul Old Telephone System
- Tieline® “Commander” a coder/decoder
- the Tieline codec device allows for data to be sent and audio received at the same time on one standard telephone line. It also provides for the transference of the audio and data in effectively real-time with no delay, thus emulating the transference rate of audio/data send/receive as if at the point of broadcast. This improved transference overcomes any significant time delays that are experienced by other 'remote' methodologies.
- the present invention provides a transcription method and system which addresses the above drawbacks and/or provides enhanced functionality, particularly for remote captioning.
- the method and system includes connecting a remote transcription site to a broadcast site utilising a secure channel established in a virtual private network, provided in a packet-switched digital communications network, such as the Internet.
- a virtual private network provided in a packet-switched digital communications network, such as the Internet.
- FIG 1 is an overview of the transcription system according to a first embodiment of the present invention.
- FIG. 2 is a flowchart showing the transcription method of the first embodiment.
- a transcription system 10 that may be separated into two main functional areas; namely remote captioning and point of broadcast.
- the system includes a number of captioning sites 12, 14 that are remotely located from a plurality of broadcast sites 22, 24, 26 transmitting a program or event.
- Each broadcast site 22, 24, 26 includes a server 22.2, 24.2, 26.2 and a codec device 22.4, 24.4, 26.4, such as the Tieline product.
- the codec device may be bidirectional and is conventionally configured to enable up to 15kHz bandwidth of high quality audio to be transported (at bit rates as low as 24,000bps) over a common telephone line (POTS) which typically has a bandwidth of only 3kHz.
- POTS common telephone line
- Each codec for example device 12.4, may conventionally be configured to accept analogue audio at two balanced inputs from a program or event soundtrack, which inputs are combined and amplitude limited prior to being digitised, preferably by a high quality 20-bit analogue-to-digital converter.
- the serial data bit stream is then fed to a 32-bit digital signal processor (DSP) that encodes the audio data using a digital audio compression algorithm, not dissimilar to that of the proprietary compression algorithm supplied by Tieline Technologies. After compression, the DSP then produces a low bit rate serial data stream that is fed to a V.34 data modem.
- DSP digital signal processor
- compressed audio data is uploaded onto a secure channel of a virtual private network (VPN) 16 for transmission.
- the codec devices 12.4, 22.4 are configured to implement TCP/IP to allow a gateway to the VPN and provide a path to the network. This ensures that the compressed audio data is routed and delivered to a receiving application at a captioning site in the correct sequence.
- the audio data is transported over the Internet 18 to be received at a remote codec device 22.4 located at captioning site 22.
- the received audio data is decompressed, fed to the digital-to-analogue converter, then amplified to line level and fed to a balanced output connector.
- the amplified analogue audio data is then transcribed into text and the text is re- transmitted to a desired broadcast site incorporating the text data according to TCP/IP onto a VPN channel 16.
- this process may be continuous and desirably occurs in real-time for the duration of the program or event requiring captions.
- browse-capable captioning software allows for the integration and remote access to the relevant broadcast server 22.2 to enable viewing of broadcast edit booths to coordinate with any program or event change. It should be appreciated, that this process of remote server access occurs in substantially real-time, and minimises the delay associated with transmission time.
- Audio stream from broadcast site 22 is sent through VPN 16 in compressed form and received at remote captioning site 12 at step 31 ;
- Server 12.2 output then routed to the remote codec device 12.4 which sends caption data via the VPN 16 to the point of broadcast 22 at step 35 (while simultaneously receiving audio from the point of broadcast codec device 22.4 via the VPN 16);
- Point of broadcast VPN 16 receives caption data and sends it on to the point of broadcast codec device 22.4, and caption data is then output by the point of broadcast codec device 22.4 to an inserter (not shown in FIG. 1) at step 36;
- Inserter encodes and inserts the caption data into the vertical blanking line of the video signal which is then broadcast to the viewer at step 37;
- the data received at the point of broadcast codec 22.4 suitably includes a flag indicating that no further audio data is required to be captioned for testing at step 38, thereby allowing termination of the captioning session at step 39 or in the absence of an end flag, allowing return of control to step 32 (above), as required.
- this transcription transmission process can function on a local, national, and international basis, and may be applied to other real-time events requiring transcription or captioning, such as CART (Communication Access Real-time Translation), court or parliamentary proceedings.
