4. The TES9 family is comprised of two models One model supports a single video stream The other model supports two video streams The TES9 can be used to add the data to the digital video stream or extract it or both Figure 1 shows the flow of video and data through the TES9 This shows that each channel is equipped with a VANC VBI decoder that provides extracted data to the CPU and a VANC VBI encoder that accepts data from the CPU for insertion into the video The CPU also has access to a variety of standard data ports RS 232 LAN and modem These facilities allow the TES9 to perform a number of functions Inserting data received from one or more of the data ports into the video This is normally 9 ce called encoding inserting or embedding e Extracting data from the video and forwarding it to one or more data ports This is 29 ce normally called decoding extracting or disembedding Inserting data extracted from one video signal into the other This is called bridging PGM PTT Serial POM 1In Vl VANC VBI LIT DL4 Encode ize 1 Out Decode RS 232 LAN modem VANC VBI Decode VANC VBI Encode ialize Video X Data Legend Figure 1 1 Simplified Block Diagram Figure 1 2 shows the pieces of equipment involved in a simple data distribution system Each of the pieces in this system is described briefly in the followin

Note A port must be assigned to the primary captioning port for the captioning Normally a caption server connected to an encoder has total control over the captioning behavior of the encoder This is true when only the primary captioning port is in use When the secondary captioning port is in use it controls the streams that it encodes into The same is true for the XDS port When you turn on a captioning port the operation of the TES9 automatically adapts to which ports control which caption streams Primary Captioning Port The settings for the Primary Captioning port are shown in the figure for the captioning module above To enable the use of the port you must select a port other than None The choices are LAN ports serial ports or modem Selecting None disables the use of the port If you selected a serial port a button appears showing the current settings for the serial port The serial port parameters may be changed by pressing the button Note The default settings for most caption servers to talk serially to a caption encoder is 9600 N 8 1 with software XON XOFF flow control Primary Port Stream Mapping Use Primary Port for applying second language from a server which is providing first language captions TES will do the mapping x Primary Port Stream Mapping Menu When you first enable the Primary Captioning Port a dialog is presented asking you how you intend to use the port shown above Select

14. Interface for LAN 9 1 Overview The LAN encoder makes use of the TCP IP protocol to transfer data Better error free data transmission is ensured since the encoder uses TCP packets as opposed to UDP packets This eliminates the possibility of lost data during transmission The basic steps to establish a connection and send data to the encoder using the winsock static library are 1 2 3 4 a 11 Initialize winsock using the WSAStartup command Get the name of the sending computer using gethostname command Get the IP address of the sending computer using gethostbyname command Copy the IP address part of the HOSTENT structure to another structure of type IN_ADDR Create a socket for making a connection using socket command In order to improve efficiency and make it possible to run multiple copies at once it is necessary to use the non blocking commands available in the winsock static library This makes use of the Windows message processing loop Do this by issuing the WSAAsyncSelect command Bind the socket created in the step above to the TCP IP protocol and accept connections for any port number using the bind command Fill structure SOCKADDR IN with the destination information Establish a connection using the connect command When connection has been established the WM_USER 100 message is sent to the Windows message loop After all data transmission is finished the sockets must be shut down usin
15. LAN can supply data as needed This is defined by the following equation T FV x DC bytes second Where e FV is the field rate for interlaced formats or the frame rate for progressive formats DC is the Data Count set for the Transparent module in TES9Set When encoding a transparent stream using data supplied through a serial port the throughput depends on the Data Count and also on the serial port baud rate The maximum throughput is the lesser of the baud rate and the data rate value resulting from the following equation DR FV x 10 x DC bits second Where e FV is the field rate for interlaced formats or the frame rate for progressive formats DC is the Data Count set for the Transparent module in TES9Set e The factor 10 in the equation reflects the fact that each 8 bit value is carried on the serial link with one start and one stop bit This is expressed in bits second to allow comparison with the serial port baud rate For example if FV 59 94 and DC 100 DR 59 940 bits second If the serial port speed is set to 57 600 bits sec the TES9 cannot fully use the capacity that has been reserved for this stream and the throughput will be 57 600 bits second If the port speed is 115 200 bits sec the TES9 will use flow control to maintain an average rate of 59 940 bits sec However if the transmit computer does not respect flow control data will be lost This points out the importance of flow control If you are not c

Paramter Descriptions Parameter Description the baud rate to set the serial port to 1200 2400 4800 9600 or baud rate 192 NOTE Since the baud rate parameter must be 4 digits or less a baud rate of 19200 is specified by the 3 digit value 192 In the above commands the space immediately after the lt CTRL A gt and immediately before the lt CR gt is not required For the lt CTRL A gt P and lt CTRL A gt N_U commands however there must be no spaces between the command type i e P or N_U and the packet type Also there is no space between the two lt CTRL F gt characters in the Reset Encoder command and there are no spaces on either side of the equal sign in commands with parameters using this format When the encoder is ready to accept a command from the transmit computer it sends the 3 character prompt sequence lt CR gt lt LF gt out the serial or LAN port being used for Captioning The hexadecimal values for the bytes in this sequence are 0D 0A 2A In order to ensure that no data is lost the transmit computer should wait until it receives the prompt from the encoder before sending each new command Note that some terminal emulators may strip lt LF gt characters from the stream The encoder handles most of the commands in the same way as Captioning Encoders designed by other manufacturers However the commands which begin with the letter N followed by an underscore are specific to the Ross Video Caption Encod
