Block generation method and apparatus, and block receiving method and apparatus

A block generation method, wherein the method comprises:

• generating a first block and a second block, wherein the first block comprises a first block unit, the second block comprises a second block unit, a first indicator is configured in the first block unit, and the first indicator is used to indicate whether the second block unit is a control code;
• sending the first block and the second, wherein
• the generating of the first block and the second block comprises:
• obtaining a first bitstream, wherein the first bitstream comprises a first control code;
• and
• compressing the first control code in the first bitstream, configuring the first indicator in remaining block space after the compression, and generating the first block and the second block.

A block receiving method, wherein the method comprises:

• receiving a first block and a second block, wherein the first block comprises a first block unit, the second block comprises a second block unit, and a first indicator is configured in the first block unit;
• and
• determining, based on an indication of thefirst indicator, whether the second block unit is a control code, wherein
• the first block further comprises a third block unit, the third block unit is before the first block unit, and a second indicator is further configured in the first block unit;
• and
• the method further comprises:
• determining, based on an indication of the second indicator, whether the third block unit before the first block unit is a control code.

A block receiving method, wherein the method comprises:

• receiving a first block and a second block, wherein the first block comprises a first block unit, the second block comprises a second block unit, and a first indicator is configured in the first block unit;
• and
• determining, based on an indication of the first indicator, whether the second block unit is a control code;
• wherein the second block further comprises another block unit, the another block unit is after the second block unit, and at least one indicator is configured in the second block unit;
• and
• the method further comprises:
• determining, based on the at least one indicator in the second block unit, whether the another block unit is a control code and whether the first block unit is a control code.

A block generation apparatus, wherein the apparatus comprises:

• a processor, configured to generate a first block and a second block, wherein the first block comprises a first block unit, the second block comprises a second block unit, a first indicator is configured in the first block unit, and the first indicator is used to indicate whether the second block unit is a control code;
• and
• a sender, configured to send the first block and the second block, wherein
• the first block further comprises a third block unit, and the third block unit is before the first block unit;
• and
• a second indicator is further configured in the first block unit, and the second indicator is used to indicate whether the third block unit before the first block unit is a control code.

A block generation apparatus, wherein the apparatus comprises:

• a processor, configured to generate a first block and a second block, wherein the first block comprises a first block unit, the second block comprises a second block unit, a first indicator is configured in the first block unit, and the first indicator is used to indicate whether the second block unit is a control code;
• a sender, configured to send the first block and the second block;
• and
• an obtaining unit, wherein the obtaining unit is configured to obtain a first bitstream, wherein the first bitstream comprises a first control code;
• and
• the processor is specifically configured to:
• compress the first control code in the first bitstream, configure a first indicator in remaining block space after the compression, and generate the first block and the second block.
