摘要： Method and apparatus to prevent hacking of encrypted audio or video content during playback. Hackers, using a debugging attachment or other tools, can illicitly access encrypted data in memory in a playback device when the data is decrypted during playback and momentarily stored in digital form. This hacking is defeated here by methodically “poisoning” the encrypted data so that it is no longer playable by a standard decoder. The poisoning involves deliberate alteration of certain bit values. On playback, the player invokes a special secure routine that provides correction of the poisoned bit values, for successful playback.

摘要： A digital electronic device includes a time shifter/tone adapter that eliminates unwanted audio effects at recipient device, that includes stutter and loss of audio synchronization, as a result of video quality adaptation (the video quality adapter varies frame rate, pixel and color resolutions without having a discernable difference in picture quality, that is, drops many frames in every frame set). The tone adaptation involves gradual frequency shifting, that is, gradual up shifting until synchronization with video is obtained (time shifting), then gradual down shifting. The recipient device (or a set top box) may contain a time shifter/tone adapter that eliminates unwanted audio effects at the recipient devices that may include stutter and loss of audio synchronization, as a result of loss of packets in channel.
摘要翻译：数字电子设备包括时移器/音调适配器，由于视频质量调整（视频质量适配器改变帧速率，像素和颜色分辨率而不改变视频质量适配器，消除了收件人设备处的不必要的音频效果，包括音频同步的声音和丢失）具有图像质量的可辨别的差异，即，在每个帧集合中丢弃多个帧）。音调适应涉及逐渐的频移，即逐渐向上移动，直到获得与视频同步（时移），然后逐渐向下移动。收件人设备（或机顶盒）可以包含时移器/音调适配器，其可以在收件人设备上消除不必要的音频效果，这些音频效果可能包括音频同步的频率和丢失，这是由于通道中的数据包丢失的结果。

摘要： An encrypted content and its encryption key under a copy right use condition of prohibiting a copy by the device having received a content are stored, and the encrypted content is copy-transferred with another device through the network, and at the same time, the encryption key is transferred through the network, so that it is stored in either one of the devices.Even when a high definition television broadcast signal received with a copy-once taken as a copy right use condition is recorded, an access flag that controls the presence or absence of the reproduction of the broadcast content for each broadcast content is provided. When an original broadcast content is transcoded into a low resolution, and is transfer to another device, its access flag is turned on, thereby making the reproduction possible.

摘要： In a home theater system having a source apparatus, a repeater apparatus and a sink apparatus connected in the recited order, when connected to a sink apparatus, whatever type it is, the repeater apparatus provides the source apparatus with video and audio signal format information that allows correct transmission. A control part 210 of the repeater apparatus 200 reads EDID information from memory 321 of the connected sink apparatus 300, and analyzes video and audio signal formats that can be processed by the sink apparatus 300, and when any format that cannot be handled by the repeater apparatus 200 itself is included, the repeater apparatus deletes information concerning that format to reconstruct the EDID information, and stores the reconstructed information into memory 221 in order to cause the source apparatus 100 to reference the stored information as EDID information of the repeater apparatus itself.
