Claim 8

A VTR with a TSC according to claim 6, wherein said order switch (29) is composed of a print film (A) on which names of countries and/or television standards are exhibited, a touch switch (B) provided with transparent electrodes which is arranged below said print film, and a light emission device (C) which is locally arranged below said touch switch so as to cause a desired portion to emit light, whereby the desired name of the country or the television standards are displayed by light emission of the light emission device through the operation of said touch switch.

Claim 9

A VTR with a TSC according to claim 6, wherein said order switch (29) displays all the names of countries adopting the same television standards as those in the designated country or the designated television standards.

Claim 10

A VTR with a TSC according to claim 1, wherein said convert control means (10) comprises a television signal standard detector (35) for detecting the television standards of an input television signal, an order switch (29) for designating a desired country name or desired television standards, and a convert mode detector (30) for detecting a conversion mode whereby said convert mode detector decides the convert mode of converting the television standards detected by the television standards detector (35) as a conver­sion source to the those designated by the order switch (29) as a conversion destination, thereby controlling the television standards converter (5) so that it converts a television signal from the signal of the conversion source to that of the conversion destina­tion.

Claim 11

A VTR with a TSC according to claim 9, wherein said convert control means (10) further comprises a light emitting displayer (41) for displaying names of countries and television standards, and said light emitting display part is driven to display the name of the television standards and country of the conversion source and those of the conversion destination.

Claim 12

A VTR with a TSC according to claim 10, wherein said convert control means (10) further comprises a display selector (39) selects either one of the name of the country or the television standards obtained by said television standards detector (35) and that designated by said order switch (29) thereby to drive said displayer (41).

Claim 13

A VTR with a TSC according to claim 11, wherein said display selector (39) is operated, in a recording mode, to select the television standards or country name designated by said order switch (29), and in playback mode, to select the television standards or country name automatically detected by said television standards detector (35) from the signal played back from a tape.

Claim 14

A VTR with a TSC according to claim 1, wherein said convert control means (10) comprises a television signal standard detector (35) for detecting the television standards of an input television signal, a first order switch (43) and a second switch (44) for designating a desired country name or desired television standards, and a convert mode detector (30) for detect­ing a conversion mode whereby said convert mode detector decides the convert mode of converting the television standards detected by the television standards detector (35) or that designated by said first order switch (43) as a conversion source to the those designated by said first order switch (42) or said second order switch (44) as a conversion destination, thereby controlling the television standards converter (5) so that it converts a television signal from the signal of the conversion source to that of the conversion destination.

Claim 15

A VTR with a TSC according to claim 13, wherein said convert mode detector (30) is operated, in a playback mode, to set the television standards detected by said television standards detector (35) as a conver­sion source and that designated by said first order switch as a conversion destination, and in the other mode, set the television standards designated by said first order switch (43) as a conversion source and that designated by said second order switch (44) as a conversion destination.

Claim 16

A VTR with a TSC according to claim 1, wherein said television standards converter (5) comprises an A/D converter (14, 16) for converting an input analog video signal into a digital signal, a memory (20) for the video signal corresponding to at least one field, a memory control circuit (21) for controlling said memory, a sync separator (18) for separating a synchroni­zation signal from said input video signal, a write clock generator from a write clock from an output from said sync separator, a read clock generator (22) for generating a read clock for reading out the data stored in said memory, and a D/A converter (23, 24) for restoring the digital signal into an analog signal.
