Method of transmitting video data, video data transmitting apparatus, and video data reproducing apparatus

A method of transmitting video data in which plural pieces of video data of plural broadcast programs are divided into packets, and the plural packets of the video data and packets including information about the broadcast programs are multiplexed and transmitted,

• wherein the packet including information about the broadcast programs is an event information table which shows the content of the video data of a broadcast program, and further wherein both video data whose reproduction mode is a non-interlace scanning mode and video data whose reproduction mode is an interlaced scanning mode are transmitted as the pieces of video data of plural broadcast programs, and information for judging whether video data of a broadcast program is of a non-interlaced scanning type or of an interlaced scanning type being described in a packet including information about the broadcast programs is described in a component identifier indicating the attribute of a video in the event information table and is transmitted in a respective scanning mode, whereby conversion between non-interlace and interlaced scanning modes is avoided.

A method of transmitting video data in which plural pieces of video data of plural broadcast programs are divided into packets, and the plural packets of the video data and packets including information about the broadcast programs are multiplexed and transmitted,

• wherein the packet including information about the broadcast programs is a network information table which shows through which channel a broadcast program is transmitted, and further wherein both video data whose reproduction mode is a non-interlace scanning mode and video data whose reproduction mode is an interlaced scanning mode are transmitted as the pieces of video data of plural broadcast programs, and information for judging whether video data of a broadcast program is of a non-interlaced scanning type or of an interlaced scanning type being described in a packet including information about the broadcast programs is transmitted in a respective scanning mode and is described in a network identifier in the program information table which identifies a network through which video data is transmitted, whereby conversion between non-interlace and interlaced scanning modes is avoided.

A video data reproducing apparatus for selecting and reproducing one of plural broadcast programs transmitted by a method of transmitting video data wherein plural pieces of video data of plural broadcast programs including interlaced scanning type video data and non-interlace scanning type video data are multiplexed with an event information table indicating the contents of the video data of each broadcast program in each time period and the information for judging whether the video data of each broadcast program included in the event information table is of a non-interlace scanning type or of an interlaced scanning type to be transmitted,

• said apparatus including a program guide forming means for forming a program guide showing the contents of each broadcast program in each time period and the scan method of the video data based on the event information table and the identification information and outputting the program guide on a display screen of a video display unit as visible information, the program guide forming means outputting only a program guide about broadcast programs whose video data is of an interlaced scanning type;
• and
• scanning method memory means for storing each program.
