Abstract
Abstract A digital data error block detection and display device which prevents incorrect operations in a receiving section due to data errors, displays block numbers containing errors, and thereby allows the operator to easily identify error-containing blocks. It is first checked whetehr a device bebug mode has been selected, and data errors are detected in digital data while transmitting the same. Digital data transmission is terminated when a data error has been detected. Digital data blocks containing data error are identified. A decision is made whether digital data including the digital block in which data error has been detected is to be transmitted. Transmission is continued of the digital data including the digital data block in which data error was detected.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
A method for transmitting blocks of digital data between a transmitting section and a receiving section, comprising the steps of: (a) determining at said transmitting section whether a device debut mode has been selected; (b) if said device debut mode has been selected, checking at said transmitting section each block of digital data to be transmitted for the presence of error; (c) transmitting to said receiving section blocks of data for which no error has been detected; (d) if an error is detected, indicating to an operator an identification of the block containing the error; (e) making a determination as to whether the block containing the error should be transmitted despite the error; (f) if it is determined in step (e) to transmit said block containing the error, transmitting said block containing the error to said receiving section and then proceeding to step (g), otherwise proceeding to step (e) without transmitting said block of data containing the error; (g) repeating steps (a) through (f); and (h) if in step (a) it is determined that said device debut mode has not been selected, then transmitting said each block of digital data.
Claim 2
Independent Claim
190 words
A method for transmitting blocks of digital data between a transmitting section and a receiving section, comprising the steps of: (a) determining at said transmitting section whether a device debut mode has been selected; (b) if said device debut mode has been selected, checking at said transmitting section each block of digital data to be transmitted for the presence of error; (c) transmitting to said receiving section blocks of data for which no error has been detected; (d) if an error is detected, indicating to an operator an identification of the block containing the error; (e) making a determination as to whether the block containing the error should be transmitted despite the error; (f) if it is determined in step (e) to transmit said block containing the error, transmitting said block containing the error to said receiving section and then proceeding to step (g), otherwise proceeding to step (e) without transmitting said block of data containing the error; (g) repeating steps (a) through (f); and (h) if in step (a) it is determined that said device debut mode has not been selected, then transmitting said each block of digital data.
Claim 3
Dependent Claim
30 words
The data transmitting method of claim 1, wherein step (e) comprises inquiring from said transmitting section to said receiving section as to the acceptability of said block containing the error.
Claim 4
Dependent Claim
23 words
The data transmitting method of claim 1, wherein step (d) comprises displaying to said operator a number of said block containing the error.
Claim 5
Dependent Claim
18 words
The data transmitting method of claim 1, wherein said blocks of data contain still-with-sound video and audio information.
